How We Analyzed 35 Social Media Post Designs
We collected 35 social creatives from product and software brands whose work performs, and coded every one against the same 25 attributes. The attributes are structural facts you can measure: where the headline sits, how large it is relative to the frame, how much of the canvas is empty, how the background is treated, whether a product or a device frame appears, how disciplined the color is, how the piece is composed, and whether there is a call to action and where.
Coding the whole set the same way is what makes patterns visible. Any single post can be explained after the fact. Thirty five of them, measured identically, show which design choices are habits and which ones carry the result.
Read the numbers as a description of what this group of creatives does. They are not a law. The sample is small and was chosen on purpose from product marketing, which is the context it is useful for. Performing, in this set, means engagement and visible traction. It does not mean revenue.
Each section below has two halves. First, what our 35 creatives do. Second, what platform guidance and published studies say on the same point, including where they disagree with us. Outside sources were opened and checked on October 11, 2026.
Social Media Post Design Findings at a Glance
Every number from the analysis in one table. The sections after it explain each row.
| Attribute | What the creatives do | Share of the set |
|---|---|---|
| Whitespace | High or extreme whitespace | 89 percent |
| Whitespace | Extreme whitespace, roughly 70 percent or more of the canvas with no content | 40 percent |
| Density | Moderately dense | 11 percent |
| Density | Crowded | None |
| Headline size | Oversized or large relative to the frame | 86 percent |
| Headline size | Oversized | 49 percent |
| Headline size | Small | 1 creative in 35 |
| Product | No product shown at all | 60 percent |
| Product | Shows a mobile app | 23 percent |
| Device frame | Uses any device frame | 37 percent |
| Format | Single image | 91 percent |
| Format | Carousel | 9 percent |
| Color | Minimal palette or strictly brand focused palette | 86 percent |
| Color | Multi color | 1 creative in 35 |
| Content type | Problem and solution framing or feature showcase, split almost evenly | 60 percent |
| Content type | Educational, announcement and social proof posts together | Less than a third |
| Hierarchy | Headline, then the problem, then the solution | 43 percent |
| Call to action | Carries a call to action | 71 percent |
| Call to action position | Of the 71 percent that carry one: bottom of the frame | 40 percent |
| Call to action position | Of the 71 percent that carry one: centered | 29 percent |
First party data from Spreadcast's own coding of 35 creatives. Almost none place the call to action at the top.
Whitespace and Headline Size: Very Large Text on a Mostly Empty Canvas
Almost nothing in the set is busy. 89 percent of the creatives sit at high or extreme whitespace, and 40 percent are at the extreme end. Only 11 percent are moderately dense and none are crowded. Restraint is the most consistent property in the whole set. It is also the property most often lost when a template gets filled with real copy.
The headline is very large. 86 percent use an oversized or large headline relative to the frame, and 49 percent are classed as oversized. Only one creative in 35 uses a small one. Put the two findings together and the dominant shape is one big statement with a lot of empty space around it.
Published design research agrees. Nielsen Norman Group's article on visual hierarchy explains that an element with more space around it gets more attention, and that attention is divided when a group holds many elements. The same article advises no more than 3 type sizes, with the most important element the biggest.
Meta's guidance points the same way. Its best practices for image ads note that people scan Feed quickly, particularly on phones, and ask for text overlays in a clean font, at a large enough size, in a contrasting hue, placed so they do not obstruct the visual. The same page states there is "no longer a limit on the amount of text" in an ad image. How much text to use is a design choice, and the answer in our set is few words, set very large.
Empty space also solves a legibility problem. Nielsen Norman Group's guideline on text over images asks for a contrast ratio of at least 4.5 to 1 between text and what is behind it, which is hard to hold over a busy photo and easy over a plain background.
Video: What Whitespace Does in a Layout
Whitespace is the finding most teams resist. Nielsen Norman Group's short explainer shows why empty space is a working part of a design and not wasted room.
Product Screenshots and Device Frames: Most Top Posts Do Not Show the Product
60 percent of the creatives contain no product at all. Only 23 percent show a mobile app and only 37 percent use any device frame. This contradicts the most repeated advice in software marketing. The likely reason is size: a screenshot at feed thumbnail scale communicates nothing, while a claim in large type does.
That does not mean the product is banned. When a product does appear in this set, it is usually in an accurate device frame at large scale, not a small screenshot floating on a gradient. Shown properly or not at all.
Meta's advice differs from our finding. Its best practices for image ads recommend showing your brand or logo, and showing people using your product or service so viewers can picture themselves doing the same. If you buy ads on Meta, weigh that guidance above a count from 35 posts.
Eyetracking research helps reconcile the two. In Jakob Nielsen's study of photos as web content, users looked closely at images that carried relevant information, such as product photos and pictures of real people, and ignored decorative filler such as generic stock photos. A product image the viewer can read is information. A tiny screenshot nobody can read works like decoration.
Faces are a separate question. A Georgia Tech and Yahoo Labs study of 1.1 million Instagram photos found that pictures with human faces were 38 percent more likely to receive likes and 32 percent more likely to receive comments. Faces are not among the attributes reported here, so this page can neither confirm nor contradict that for brand graphics.
Single Image vs Carousel: Where Our Set and the Benchmarks Disagree
91 percent of the creatives are single images. Only 9 percent are carousels, in a period when every channel guide recommends carousels. A single image carries one idea, and one idea is what survives a scroll.
Large benchmark studies point the other way on engagement rate. Socialinsider's Instagram benchmarks, based on 35 million posts from 2025, put carousels at 0.55 percent engagement by followers, Reels at 0.52 percent and static images at 0.37 percent. Buffer's 2026 analysis of content formats reports a median engagement rate, measured against reach, of 6.9 percent for Instagram carousels, 4.4 percent for single images and 3.3 percent for Reels. On LinkedIn, Buffer has carousels at 21.77 percent against 6.52 percent for images. Rival IQ's 2025 benchmark report also found carousels ahead of Reels on Instagram.
The two kinds of evidence measure different things. Ours counts which formats appear in a hand picked set of standout creatives. The benchmarks average the engagement of millions of ordinary posts per format. Both can be true: most standout single posts are single images, and the average carousel still collects more interactions than the average image.
So do not read 91 percent as an instruction to avoid carousels. They do a different job. Our set leans toward creatives that stop a scroll, which single images do well because they carry one idea. Carousels earn their place on depth, in education and tutorials, where the reader has already stopped. Buffer adds a third angle: Reels reach 2.25 times as many people as single images, so the right format depends on whether you want reach or interaction. For carousel structure, see our LinkedIn carousel examples.
Color: Two or Three Colors per Post
86 percent of the creatives use a minimal palette or a strictly brand focused one. Only one creative in 35 is multi color. The visual identity is carried by restraint and typography, not by range, and that is what makes a grid of posts read as one company.
Nielsen Norman Group gives nearly the same rule for interfaces. Its visual hierarchy guidance says to limit simple designs to 2 primary and 2 secondary colors, because too many colors of similar strength weaken the sense of what matters most.
Other sources are looser or look at a different question. Meta's image ad advice only asks for appealing colors that suit the content, such as bright tones for a summer sale. A peer reviewed study in PLOS ONE, the colors of diffusion on Pinterest, analyzed one million pins and found that red, purple and pink were linked to more repins while green, blue, black and yellow were linked to fewer. That result is about which hue spreads on one network. Our finding is about how many colors a post uses. Do not repaint a blue brand pink because of it.
Whatever the palette, check that text is readable on it. Our brand style guide template shows how to write down allowed color pairs with their contrast ratios.
Content Type and Call to Action: One Message, Button at the Bottom
Two content types dominate. 60 percent of the creatives are either problem and solution framing or a feature showcase, split almost evenly. 43 percent follow the same hierarchy: headline, then the problem, then the solution. Educational, announcement and social proof posts together account for less than a third.
71 percent carry a call to action. Of the 71 percent that carry one, 40 percent place it at the bottom of the frame and 29 percent center it. Almost none put it at the top, where it would compete with the headline for the same attention.
Meta's guidance on text overlays and safe zones supports the single message: it advises against communicating too many messages, because an ad usually has only one call to action. It also adds a practical limit to the word bottom. For Instagram Feed ads in 1:1 or 4:5, Meta asks you to keep the bottom and side edges free of key elements, text and logos, since the app interface can cover them. Place the call to action low in the frame, with a margin under it.
Where Published Research Agrees and Disagrees With Our Findings
| Our finding | Outside source | Verdict |
|---|---|---|
| 89 percent high or extreme whitespace | Nielsen Norman Group on visual hierarchy: more space around an element brings it more attention. | Agrees |
| 86 percent oversized or large headline | Meta's image ad best practices: large enough type, contrasting hue, people scan quickly on phones. | Agrees |
| 60 percent show no product | Meta's image ad best practices: show your brand or logo, show people using the product. | Disagrees |
| Product shown large and accurately when it appears | Nielsen's eyetracking on photos: informative product images get attention, decorative ones are ignored. | Agrees |
| 91 percent single images, 9 percent carousels | Socialinsider, Buffer and Rival IQ: carousels have the higher average engagement rate on Instagram. | Disagrees on engagement rate, measures a different thing |
| 86 percent minimal or brand focused palette | Nielsen Norman Group: limit simple designs to 2 primary and 2 secondary colors. | Agrees |
| One call to action, placed at the bottom | Meta on text overlays: one message per ad, and keep the bottom edge clear on Instagram Feed. | Agrees, with a margin |
Outside sources opened and read on October 11, 2026. Benchmark figures change every year.
The Composite: What a Typical High Performing Post Looks Like
Take the most common value of every attribute and a specific creative appears. It is a single image. The headline is oversized and centered, sits at the top of the visual hierarchy, and states a problem. Around 70 percent of the canvas is empty. The background is minimal or a restrained gradient. There is no photograph and no product screenshot. The palette is two or three colors. There is a call to action, and it sits at the bottom.
That composite is close to the opposite of what most teams make when handed a template library: a filled frame, a medium headline, a product shot, three accent colors and no clear hierarchy. The gap is not talent. A template rewards filling the space it gives you, and this set is defined by leaving space empty.
The composite also shows how few decisions are in play. Position, size, density, palette discipline, one content type, one call to action. Six decisions, made the same way every time, account for most of the difference, and six is few enough to write down as rules.
Six Social Media Design Tips Taken From the Data
These are the six decisions from the composite, written as steps. Use them as a starting point for social media post design ideas of your own, then test against your own results.
- Step 1
Put the Headline First
Give the headline the top of the visual hierarchy and center it. In the composite, it is the first thing the eye reaches and it states a problem the viewer has.
- Step 2
Make the Headline Oversized
86 percent of the set uses an oversized or large headline. If the headline still reads at thumbnail size on a phone, it is large enough. Cut words before you cut size.
- Step 3
Leave Most of the Canvas Empty
Aim for the level the set shows: high or extreme whitespace, which at the extreme end means roughly 70 percent or more of the canvas with no text, product or graphic on it.
- Step 4
Hold the Palette to Two or Three Colors
Use your brand colors and stop there. Only one creative in 35 is multi color. A plain or softly graded background keeps the text readable.
- Step 5
Pick One Content Type per Post
The two most common are problem and solution, and a single feature showcase. Do not combine a feature list, a quote and an announcement in one image.
- Step 6
Add One Call to Action at the Bottom
71 percent of the set carries a call to action, most often at the bottom. Keep it clear of the very edge, where the app interface can cover it.
Video: Five Visual Design Principles Used to Critique a Layout
Each of the six tips is an application of a few older principles. Nielsen Norman Group walks through them on real screens, which makes a useful checklist for reviewing a draft post.
How to Design Social Media Posts Step by Step, in Canva, Figma or Any Editor
The six tips say what a finished post looks like. This is the order of work that gets you there, and it is the same whether you design social media posts in Canva, in Figma, in Photoshop or in a slide app. The editor changes the buttons, not the steps.
- Step 1
Write the Post Before You Open the Editor
Write the headline, one supporting line and the call to action in a note. Count the headline words. If the headline is longer than about eight words, cut it now, because a long headline is the usual reason a post ends up with small type and no empty space.
- Step 2
Set the Canvas and the Margin
Start a 1080 by 1350 canvas for a feed post, then draw a margin on all four sides and treat it as a wall. Meta's safe zone advice, cited above, is the reason: the edges of a feed post are where the app's own buttons and crops land. For other networks, take the size from the social media image sizes reference.
- Step 3
Load the Brand Before the First Element
Set the background color, the headline font and the text color from your brand kit before you place anything. In Canva that is the Brand Kit panel, in Figma it is published styles. Choosing colors halfway through is how a fourth and fifth color sneak in.
- Step 4
Place the Headline, Then Stop and Look
Put the headline in the top half, at the largest size that fits inside the margin. Before you add anything else, look at the canvas at phone size. In the findings, most standout posts are close to finished at this point.
- Step 5
Add One Supporting Element or None
Add the screenshot, the number or the quote that proves the headline, large enough to read at feed size. If you are tempted to add a second element, that is usually a second post. Then place the call to action low in the frame, inside the margin.
- Step 6
Check, Export and Keep It as a Template
Run the one minute checks from the table above, export the file at the canvas size, and look at it on a real phone before you post. Then save the file as the template for that type of post, so the next one starts from a layout that already follows your rules.
What Each Finding Means in Practice: A One Minute Check for Your Own Post
The numbers are the ones from the table at the top of this page. The middle column turns each into a working habit, and the right column is a test you can run on a draft before you publish it.
| Finding in the set | What it means while you design | A check you can run in a minute |
|---|---|---|
| 89 percent high or extreme whitespace | Write the headline, place it, and stop adding. Every other element has to earn its place on the canvas | Blur the draft or squint at it. Nielsen Norman Group's visual hierarchy article describes this squint test: whatever still stands out when the design is blurred is the real hierarchy |
| 86 percent oversized or large headline | A headline can only be that large if it is short. When it wraps to four lines, cut words and keep the size | Shrink the draft to the size of a phone thumbnail. If the headline cannot be read there, it is too small or too long |
| 60 percent show no product | A post can be a claim and nothing else. If the product appears, give it most of the frame | Ask whether a stranger could tell what the screen shows without zooming. If the answer is no, enlarge it or remove it |
| 91 percent single images | One idea per post. A second idea is a second post | Say the point of the post in one sentence. If the sentence needs the word and, split the post |
| 86 percent minimal or brand focused palette | Background, text and one accent are enough | Count the colors, leaving out any screenshot. A fourth color is usually the one to drop |
| 60 percent problem and solution framing or feature showcase | Decide which of the two this post is before you open the editor | Name the content type out loud. A draft that is two types at once is the one to rework |
| 71 percent carry a call to action, most often at the bottom | One action, low in the frame, and much smaller than the headline | Look at the bottom edge of the export. The call to action should sit above it with a clear margin |
Reading research gives the short headline some background. In Jakob Nielsen's 1997 study of how users read on the web, 79 percent of test users scanned a new page and 16 percent read it word by word. The study is old and concerns web pages, so treat it as context for the finding and not as proof of it.
Before and After: Three App Posts Redesigned With the Findings
Three worked examples for an invented running app called Pacewise. None of this is a real post or a real result. Each pair describes a typical first draft and then the same post after the six decisions above are applied.
App Update Post: Before
A screenshot of the new screen sits in the middle at half size. Above it, New in Version 2.4 in medium type. Below it, five bullet points copied from the release notes, the app icon, a store badge and a web address, in four colors. Nothing in it is wrong, and nothing in it comes first.
App Update Post: After
The headline is oversized and sits at the top: Your Runs Now Sync Without Your Phone. Under it is one screen, large, cropped to the part that changed. At the bottom, in small type: Version 2.4, on the App Store. Two colors plus the screenshot. The other four changes move to the caption.
Review Post: Before
A phone mockup holds a screenshot of the review, with the reviewer's words at the size they have in the store. Around it: a row of stars, the app icon, the line What Our Users Say and a gradient. The review is the whole point of the post and it is the smallest thing on the canvas.
Review Post: After
The strongest sentence of the review becomes the headline, in quotation marks, very large on one plain brand color. Below it, small: five stars, the reviewer's name as the store shows it, and the app name. One call to action at the bottom. Ask the reviewer before you post it, since Apple requires permission.
Rating Milestone Post: Before
Thank You in a script typeface, confetti, the number of ratings, the average, a screenshot, a download button and three hashtags inside the image. Every element is cheerful and they all compete at the same size.
Rating Milestone Post: After
One number is the headline: 1,000 Ratings. One line sits under it: 4.8 average, thank you. Empty space surrounds both, the brand color is behind them, and the app icon is small at the bottom. Check the figure against the live listing on the day you post, because Apple's ratings and reviews rules allow a rating in marketing only while it reflects the current one.
Common Social Media Post Design Mistakes, Read Against the Data
Each mistake is the reverse of one row in the findings table. Where a platform or a research group has said the same thing, the source is linked. The sources added in this part of the page were opened on October 12, 2026.
Filling the Template
A template arrives with boxes, and boxes ask to be filled. None of the 35 creatives is crowded and only 11 percent are moderately dense. Delete the placeholder you have nothing to say in.
A Headline the Size of Body Text
Only one creative in 35 uses a small headline. Nielsen Norman Group's principles of visual design explain why size matters: larger elements signal more importance, and a pleasing design generally uses no more than 3 different sizes.
Three Small Screenshots in a Row
The set shows the product large and accurately, or leaves it out. Three screens side by side on a feed post are each about a third of the width of a phone, and the text inside them is too small to read.
A New Accent Color for Every Post
Only one creative in 35 is multi color. Changing the accent from post to post feels like variety from the inside. From the outside it stops the grid from reading as one company.
Two Messages in One Image
A feature, a discount and a quote in one frame give the viewer three things to weigh in the second they spend on it. Meta's guidance on text overlays, linked above, advises against communicating too many messages.
A Call to Action on the Very Edge
Bottom is where the set puts it. The bottom edge itself is where the app interface can cover it, according to Meta's safe zone guidance. Leave a margin under the button.
Light Text on a Light Background
An oversized headline can get by with less contrast than small type, and the small type is where posts fail. The W3C guidance on minimum contrast asks for 4.5 to 1 for text and 3 to 1 for large text, which it defines as 18 point or 14 point bold. The version number and the call to action are small text, so hold them to 4.5 to 1.
Social Media Post Design Ideas for an App: Ten Posts That Fit the Findings
Ideas are the easy part to search for and the hard part to keep consistent. Each idea below is one message that fits a single image with an oversized headline, which is the shape the findings favor. The examples use Streakly, an invented habit tracker.
The One Feature Post
One thing the app does, as a headline in the user's words, with one large screen. "See every habit on one calendar." This is the feature showcase, one of the two most common content types in the set.
The Problem Post
Name a problem your users have, then answer it in one line. "Forgot to log yesterday? Log it until noon." Problem and solution framing is the other dominant type, and it often needs no screenshot at all.
The One Number Post
A single true number as the headline: ratings, days, users, a streak record from your own data. "1,000 ratings." Keep everything else small. Never round up, and check the figure on the day you post.
The Review Post
The best sentence of a real review, very large, in quotation marks, with the reviewer's name small underneath. Ask the reviewer first. The before and after example above shows the layout.
The Update Post
The one change in a new version that users will feel, as the headline, with the version number at the bottom. The rest of the release notes go in the caption.
The Tip Post
One way to get more out of the app, written as an instruction. "Long press a habit to skip a day." A tip post is useful to people who already have the app, which keeps them following.
The Old Way, New Way Post
Two short lines, the first crossed out or set in a quieter color: the way people did it before, then the way the app does it. Keep it to two lines so it still reads as one idea.
The Question Post
One question as the headline, such as "What habit are you starting this month?" No product, lots of space. Questions invite comments, and the replies give you ideas for the next posts.
The Behind the Build Post
One sentence about why you made a decision in the app, with a sketch or an early screen. Founders posting about their work is a common way small apps build an audience, as our mobile app marketing examples show.
The Short Carousel for a How To
When a tip needs three steps, make a carousel: a cover with the headline, one step per slide, and a last slide with the call to action. The findings favor single images for stopping a scroll, and benchmarks favor carousels for teaching. Use each for its job.
Social Media Post Design Size: The Canvas These Findings Assume
The findings describe what goes on the canvas, and they assume a vertical feed post. Meta's image ad guidance, cited above, recommends a vertical 4:5 ratio for single image ads in Facebook Feed. LinkedIn's help page on photo posts recommends a width of 1080 pixels and accepts aspect ratios from 3:1 to 4:5, so an image of 1080 by 1350 pixels, which is 4:5, is as tall as LinkedIn will show in full.
Whitespace in our coding is a share of the canvas, so the finding scales with the format. A 1080 by 1350 canvas holds 1,458,000 pixels. Extreme whitespace, roughly 70 percent or more of the canvas with no content, means about a million of them carry nothing but the background. On a square 1080 by 1080 canvas the same share leaves the headline less room in absolute terms, which is one more argument for the taller format.
Dimensions for each network, with the platform pages they come from, are in our social media image sizes reference.
Limits of This Analysis: Where Not to Trust the Numbers
Thirty five is a small sample and it is not random. The creatives were chosen because they perform in product and software marketing. The findings describe that context and probably travel badly to a restaurant or a local service business, where photography does much more of the work.
Performance here means engagement and visible traction. Attributed revenue is a different thing, and the two differ most on calls to action. A creative can earn attention and sell nothing.
The codings are judgements. Whitespace level and composition style in particular involve a call at the margin. The large patterns (whitespace, headline size, single image dominance and palette discipline) are wide enough that reasonable disagreement at the edges does not move them. The narrower findings should be read as suggestive.
We publish the coded attributes and leave out the source images, because the images belong to the brands that made them. As of October 11, 2026 the sample is still 35.
Social Media Post Design With AI: How to Create Social Media Posts With Claude or ChatGPT
AI tools can now draft a whole post, and the findings on this page are a good brief to give them. The trouble is that most AI design output fails in the same direction as most templates: it fills the canvas. An image model asked for an app post can invent a phone with a screen that does not exist, add three colors you do not use, and set a headline at a modest size because it is balancing many elements. Every one of those choices runs against the composite above.
The fix is to split the job. Ask the assistant for the words and the decisions, and let a layout tool place your real assets. A prompt that works: "Write a headline of eight words or fewer for this update, one supporting line and one call to action. Tell me which one screen to show. The post is a single 1080 by 1350 image, mostly empty, with two brand colors." You get copy that fits the layout instead of a layout bent around long copy.
Never let a model draw your product. A screenshot an AI invented shows features your app does not have, and anyone who downloads the app will notice. Use your real screenshots, in an accurate frame or with no frame, which is the pattern the set follows when it shows a product at all.
Spreadcast gives Claude and ChatGPT a tool that works this way. Through its MCP server at spreadcast.app/api/mcp, the assistant can design a post or a carousel of 3 to 8 slides from your own brand kit: your colors, fonts, logo and real app screenshots in an iPhone frame, in 11 kinds of post such as feature, stat, tutorial and problem and solution. It lays out your assets and makes no AI photos. The post is saved as a draft for you to approve. Setup is on the MCP page and the social media MCP server page, and prompts to start from are in Claude prompts for social media.
How the Findings Apply to Social Posts for an App
Two kinds of post matter most for an app team: an update post when a version ships, and a review post when a user says something kind. If you came here for app ad creative examples, these are the two to start with.
An update post is a feature showcase, one of the two dominant content types in the set. Pick the one change users will care about, and write it as the headline in their words. If a screenshot appears, follow the pattern from the set: one screen, large, in an accurate frame or with no frame, never three small screens in a row. Put the version number and the App Store call to action at the bottom. Wording you can borrow is in our app update announcement examples.
A review post is social proof, which is a minority content type in this set, so the data gives less direct guidance. The structural findings still carry over: make the quote the headline, set it very large on a plain background, hold to two or three brand colors, and keep the star rating and app name small at the bottom. Before quoting, remember that Apple's ratings and reviews rules allow a review in marketing only with the reviewer's permission. Our summary of the App Store marketing guidelines covers that rule, and the testimonial graphic generator page covers the layout.
Spreadcast makes both kinds of post from your App Store listing. Each one is a single still image at 1080 by 1350 with typeset text and colors read from your app icon, which lines up with the single image and palette findings above. The automatic posts are single images. Carousels of 3 to 8 slides are made on request, through the MCP server described above. A post that shows only your rating can go out by itself, and a post that quotes a review waits for your approval. To try it, paste your App Store link, or read what makes a social creative convert for the longer argument.
Frequently Asked Questions
How do you design a social media post that gets attention?
In our set of 35 high performing creatives, the common pattern is one oversized headline, a mostly empty canvas, two or three brand colors, one message and one call to action at the bottom. 89 percent sit at high or extreme whitespace and 86 percent use an oversized or large headline.
Can I see the 35 creatives you analyzed?
We publish the coded attributes and leave out the source images, since those belong to the brands that made them. The value is in the distribution anyway. Any single creative can be explained after the fact, and only the set shows which choices repeat.
Should a social media post show the product?
Only when the product image can be read. 60 percent of our set shows no product, and when one appears it is usually in an accurate device frame at large scale. Meta takes a different view for ads: its image ad best practices recommend showing people using your product.
Are carousels better than single images?
It depends on what you measure. 91 percent of our standout creatives are single images. Across millions of ordinary posts, though, Socialinsider's benchmarks and Buffer's format study both show carousels with a higher average engagement rate on Instagram. Use single images to stop a scroll with one idea, and carousels for teaching.
How much text should a social media image have?
No platform rule sets a number for Meta anymore: its image ad guidance says the limit on text in ad images is gone. Our set suggests a short headline in very large type. If the text has to shrink to fit, there are too many words.
What does extreme whitespace mean in practice?
Roughly 70 percent or more of the canvas carrying no content: no text, no product, no graphic element. In the coded set, 40 percent of creatives sit at that level, which is considerably emptier than most teams are comfortable publishing.
Where should the call to action go on a social media post?
At the bottom. Of the 71 percent of creatives that carry one, 40 percent place it at the bottom of the frame and 29 percent center it. Almost none put it at the top. On Instagram Feed, Meta's safe zone guidance says to keep key elements off the bottom edge itself.
What size should a social media post design be?
For a single image in the feed, vertical 4:5 is the safe default. Meta's best practices recommend 4:5 for single image ads in Facebook Feed. Dimensions for every network are in our social media image sizes reference.
What are good social media post design ideas for an app?
Posts that carry one message each: one feature with one large screen, a problem and its answer, one true number, the best line of a review used with permission, the one change in an update, a tip, a question, or a short carousel for a how to. The ten ideas above show each one.
Can I design social media posts with Claude or ChatGPT?
