TikTok carousel design tips: hooks, readability and accessibility
By Harmony Crafted · · 5 min read
Carousels are read, not just watched: viewers swipe at their own pace (TikTok Newsroom). That makes clarity and readability the main design job. These tips focus on what you control.
1. Make slide 1 a promise
The first slide decides whether anyone swipes. State the payoff ("5 mistakes that…", "Before / after"), keep it to a few words, and make it legible at thumbnail size. Use CarouselStats' OCR-based analytics to see the opening text of a creator's best-performing carousels.
2. One idea per slide
Each swipe should deliver one point. If a slide needs a paragraph, split it into two. Number list-style slides so readers know how far they are through.
3. Text contrast you can measure
The W3C's accessibility guidelines (WCAG 2.1, criterion 1.4.3) set a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text (W3C). Text over photos usually fails this unless you add a solid or semi-opaque band behind it. Check your colors with any contrast checker.
4. Keep text away from the edges
TikTok overlays the caption, creator name and action buttons on the post. Keep key text toward the center so it isn't covered, and preview the post on a phone before publishing.
5. Add alt text
TikTok rolled out alt text for photo posts in April 2025 so creators can describe images for people using screen readers (TechCrunch). It takes seconds and makes your carousel usable by more people.
6. Use the caption for context
TikTok allows descriptions of up to 2,200 characters on Photo Mode posts (TikTok Newsroom). Use it to summarize the carousel, add sources, and say what to do next.
7. Design for likes and saves, test for shares
In Fanpage Karma's 2025 study, TikTok carousels had higher like and engagement rates than videos but about a third fewer shares (source; see our breakdown). If shares matter, give people a reason to send it — a checklist, a relatable punchline, a "send this to…" final slide.
8. Study what works
Save carousels you admire with the downloader (for reference, not reposting) and compare their structure: slide count, hook wording, where the call to action sits.
