Designing social posts and carousels

The job of a social post

A feed post must do three things in order: stop the scroll, deliver the message, and prompt a next step (save, share, comment, tap, visit). Your design choices should serve those jobs in that order.

Single-image posts

Structure most single posts around one idea:

Hook (primary):     big statement, question, number or striking image
Support (secondary): one line of context or proof
Signature (tertiary): handle/logo, consistent position
Action (optional):  "Save this", "Comment 'guide'", etc. — often better in the caption

Patterns that work well for creators and small brands:

  • Big statement: one bold sentence on a clean background.
  • Quote card: a quote with attribution and optional headshot.
  • Before/after or comparison: two-column layout with clear labels.
  • Single statistic: one large number with a source (never invent statistics — cite real sources or mark numbers as illustrative).
  • Product hero: product photo, benefit headline, price or offer.

Carousels: the mini-presentation

Carousels reward saves and deep engagement when they teach or tell a story. Plan them like a short deck.

| Slide | Purpose | Design notes | |---|---|---| | 1 — Cover | Hook: promise a clear benefit or curiosity | Largest type, strongest contrast, a visual cue to swipe | | 2 | Context or problem | Keep it short; build tension | | 3–8 | One point per slide | Consistent layout, numbered steps | | Second-to-last | Summary or recap | Useful for saves | | Last | Call to action | Follow, save, share, comment keyword, visit link |

Design system for a carousel:

  • Same grid, margins and type styles on every slide.
  • A progress cue (slide numbers such as "3/8", or a subtle progress bar).
  • A visual element that continues across slides can encourage swiping — for example a line or shape that crosses the edge.
  • One idea per slide; if the text needs to shrink to fit, split the slide.

Stories and vertical posts

  • Design in 9:16 with generous safe areas at top and bottom.
  • Use interactive features (polls, questions, links) as part of the design, leaving space for them.
  • Keep text short; people tap through quickly.

Captions complement design

The caption can carry details, context, hashtags and disclosures, while the image carries the hook. However:

  • Advertising disclosures (for example "#ad", "Paid partnership" labels, or the platform's branded-content tool) must be clear and prominent. Many regulators — including the FTC in the US, the ASA/CAP in the UK, and authorities in the UAE and Saudi Arabia that regulate influencer advertising — expect disclosure to be obvious before people engage, not hidden in a hashtag pile or "see more". Consider putting disclosure on the image itself for paid content.
  • Anything essential for understanding the offer (price conditions, key limitations) should not be buried.

Worked example: a "5 mistakes" carousel for a freelance designer

  • Cover: "5 portfolio mistakes that cost you clients" in huge type; a small red "✕" motif; "Swipe →".
  • Slide 2: "Clients decide in seconds. Here's what makes them leave."
  • Slides 3–7: each mistake numbered, headline plus one sentence of fix; the red ✕ motif in the same corner; slide number bottom-right.
  • Slide 8: recap list of all five.
  • Slide 9: "Want a portfolio review? Comment 'REVIEW'." with the designer's photo and handle.

Writing on-image copy

Design and copywriting work together. Keep on-image text short and concrete: use numbers, specific outcomes and plain words rather than jargon. Front-load the key words so the phrase still works if someone only reads the first three words. Read every slide aloud; if it sounds like a paragraph, it is too long for a graphic. Finally, match the tone of the copy to the visual style — a playful illustration with formal corporate text feels disjointed.

Post and carousel QA checklist

[ ] Cover passes the one-second test at feed size
[ ] One idea per slide/post
[ ] Consistent grid, type and colors across slides
[ ] Progress cue and swipe cue present (carousels)
[ ] Numbers and claims are real and sourced, or labeled illustrative
[ ] Paid/affiliate content disclosed clearly and early
[ ] Alt text written

Common mistakes

  • A weak cover that does not promise anything.
  • Walls of text on slides.
  • Inconsistent layouts between slides.
  • Hiding sponsorship disclosure.

Hands-on: a carousel build sheet and QA

CAROUSEL PLAN — topic: __________  format: 4:5 (1080×1350)  slides: 7-10
Promise (cover):  ______________________ (benefit or curiosity, ≤ 8 words)
Slide 2 (context): _____________________
Slides 3-8: one point each → headline (≤ 6 words) + one supporting line
Recap slide: ___________________  CTA slide: ___________________
Constants: grid ___  type styles ___  accent ___  progress cue ___  handle position ___
Disclosure needed? (#ad / paid partnership / AI label) ___  where: cover + caption
Alt text per slide (where the platform supports it): yes/no

Post and carousel QA checklist

  • Cover readable at grid-thumbnail size, with a clear reason to swipe.
  • Same grid, margins and styles on every slide; slide numbers in the same place.
  • One idea per slide; nothing shrinks to fit.
  • All statistics sourced (or clearly labeled illustrative).
  • Contrast passes (4.5:1 normal text, 3:1 large) on every slide.
  • Disclosures visible on the image for paid content, not only in hashtags.
  • Profile-grid crop checked: Instagram now previews posts in the profile grid at a taller 3:4 shape, so keep the cover's key content central.

Figma tip: build a carousel as one wide frame

Create one long frame (for example 1080 × 1350 per slide × 8 slides = 8640 × 1350) with a column layout grid of 1080-wide columns, or eight separate frames inside an auto-layout row. A continuous line or shape crossing slide edges then lines up perfectly; export each slide by slicing (separate frames export individually).

Before/after: a "5 mistakes" carousel cover

| | Before | After | |---|---|---| | Headline | "Some thoughts on portfolio design and common issues I see" | "5 portfolio mistakes that cost you clients" | | Visual cue | None | Red ✕ motif + "Swipe →" | | Type | 40 px regular | 96 px heavy, two lines | | Grid preview | Headline cut at the top in the profile grid | Headline centered inside the 3:4 preview area |

Summary

Design posts to stop, deliver and prompt; plan carousels like short decks with a strong cover and one idea per slide; and keep disclosures and claims honest and visible.

Lecture transcript

Posts and carousels

Let's say you've got something genuinely useful to share. Five mistakes people make with their portfolios. You write it all on one image, in small text, and post it. It gets a few likes. Then another creator posts the same idea as a nine-slide carousel, with a bold cover, one mistake per slide, and a recap at the end. It gets saved and shared hundreds of times. Same content. Different design. In this lecture, you'll learn the three jobs of a social post, how to structure single-image posts, how to plan carousels like mini presentations, how to design stories, and how captions and disclosures work alongside the design. By the end, you'll have a carousel build sheet and a QA checklist you can use every week.

Three jobs of a post

Why does structure matter so much on social? Because every post has three jobs, in order. Stop the scroll. Deliver the message. Prompt a next step, like save, share, comment or tap. If the design fails job one, nothing else matters. If it nails job one but fails job two, people feel tricked. And if it skips job three, you lose the moment. Think of a good shop window. It catches your eye from across the street. Up close, it shows you something specific. And the door is right there. Your post is the shop window, and the design decides whether people walk in.

Single-image posts

Let's start with single-image posts. Structure them around one idea. The hook, your primary element: a big statement, a question, a number or a striking image. The support, secondary: one line of context or proof. The signature, tertiary: your handle or logo, always in the same position. And the action, which is often better in the caption: save this, or comment guide. Patterns that work well include a big statement on a clean background, a quote card, a before and after comparison with clear labels, a single statistic with its source, and a product hero with a benefit headline. Here's the key idea. One post, one idea. If you have five ideas, you have a carousel.

Carousel structure

Now carousels, which are really mini presentations. Slide one is the cover: a clear promise or curiosity hook, the largest type, the strongest contrast and a visual cue to swipe. Slide two gives context or the problem. Slides three to eight each make one point, with a consistent layout and numbered steps. The second-to-last slide is a recap, which people love to save. And the last slide is the call to action: follow, save, share, comment a keyword or visit a link. The design system stays constant: same grid, margins, type styles, a progress cue like three of eight, and maybe a shape that crosses slide edges to encourage swiping.

Stories, captions, disclosures

Stories and vertical posts have their own rules. Design in nine by sixteen with generous safe areas at the top and bottom, because the app puts your profile, reply bar and buttons there. Leave space for interactive features like polls, questions and link stickers, and design them in. Keep text short, because people tap through quickly. And the caption. It complements the design. It can carry details, context and hashtags. But anything essential, like price conditions, and any advertising disclosure, must be clear. Regulators such as the FTC in the US and the ASA in the UK, and authorities in the UAE and Saudi Arabia, expect paid content to be obvious before people engage. For paid posts, put the disclosure on the image too.

Worked example 1: '5 mistakes' carousel

Worked example one, simple. A freelance designer's five portfolio mistakes carousel. The original cover said: some thoughts on portfolio design and common issues I see, in forty pixel regular type. The new cover: five portfolio mistakes that cost you clients, at ninety-six pixels heavy, on two lines, with a small red cross motif and swipe with an arrow. Slide two: clients decide in seconds, here's what makes them leave. Slides three to seven: one mistake each, a short headline plus one sentence with the fix, the red cross in the same corner, and the slide number bottom right. Slide eight: a recap. Slide nine: want a portfolio review, comment review, with the designer's photo and handle.

Worked example 2: a paid skincare carousel

Worked example two, a business scenario with illustrative details. A skincare brand in Dubai runs a paid partnership with a creator, delivered as a carousel. The first draft hid the disclosure in a pile of hashtags at the end of the caption, and the cover's headline was cut off in the profile grid. The fix. The paid partnership label is switched on in the app. Ad appears at the start of the caption, and a small ad label sits on the cover itself. Every before and after image uses real, unedited results with consent, and the claims were checked against evidence. And because the profile grid now previews posts at a taller three by four shape, the headline is moved to the center of the cover, so it survives the crop.

Watch me do it: a carousel in Figma

Watch me do it in Figma. I create eight frames at ten eighty by thirteen fifty, inside a horizontal auto layout row with no gap, so they sit edge to edge. I apply my grid, type styles and colors to the first frame, then duplicate it. On the cover, I set the headline at ninety-six pixels heavy and add a swipe cue. I draw a thin accent line that starts on slide one and crosses into slide two, because the frames touch, so it lines up perfectly. I add slide numbers bottom right on every slide. Then I fill in the build sheet: one point per slide, recap and call to action. I run the QA list, check contrast, and export each frame as its own image.

On-image copy

A few words about on-image copy, because design and writing work together. Keep it short and concrete. Use numbers, specific outcomes and plain words instead of jargon. Front-load the key words, so the phrase still works if someone reads only the first three words. Read every slide aloud. If it sounds like a paragraph, it's too long for a graphic. And if you use statistics, cite real sources or clearly mark numbers as illustrative. Made-up stats are one of the fastest ways to lose trust, and in ads, they can break advertising rules.

Common mistakes

Common mistakes. Covers that don't promise anything. Cramming several ideas into one slide and shrinking the text. Changing layouts between slides, so the carousel feels messy. No progress cue. No recap. A call to action on the first slide instead of the last. Disclosures buried in hashtags. Ignoring the profile grid crop. And posting without checking contrast on every slide. Use the post and carousel QA checklist from the lesson before every publish. It takes three minutes and catches almost all of these.

Recap and try this now

Let's recap. Every post has three jobs: stop the scroll, deliver the message, and prompt a next step. Single-image posts carry one idea. Carousels are mini presentations: a cover with a promise, one point per slide, a recap and a call to action, all on a constant system. Stories need safe areas and space for stickers. Captions complement the design, and disclosures must be clear, early and, for paid content, on the image too. Try this now. Plan a seven to nine slide carousel using the build sheet from the lesson. Sketch each slide on the same grid, run the QA checklist before you design it fully, and check the cover at grid-thumbnail size.

Key takeaways

  • Every post has three jobs in order: stop the scroll, deliver the message, prompt a next step.
  • Single-image posts carry one idea: hook, support, signature and (often in the caption) action.
  • Carousels are mini presentations: promise on the cover, one point per slide, recap, CTA — on a constant system with a progress cue.
  • Design stories in 9:16 with safe areas and space for interactive stickers.
  • Paid content needs clear, early disclosure — use the platform tool, the caption start and the image itself.

Try it

Plan a 7–9 slide carousel using the slide table, sketch each slide on the same grid, and run the QA checklist before designing it fully.
