Text Overlay Best Practices for App Screenshots

Why This Matters

Font sizes, contrast ratios, positioning, and readability rules for screenshot text overlays. What works at thumbnail size.

App Store screenshots are the single highest-leverage conversion element on your listing page. While your icon gets people to notice you, and your title/subtitle get the click, screenshots are what close the download. Getting this right can mean the difference between 100 and 10,000 daily downloads.

Key Takeaways

• Design for the thumbnail first. Most users see your screenshots at ~150px wide in search results and browse views. If your message isn't readable at that size, it doesn't exist.
• Lead with your strongest value prop. Screenshot #1 gets 5x the attention of screenshot #5. Don't waste it on a splash screen or logo.
• Use all available screenshot slots. Apps that use all 10 App Store slots (or 8 on Google Play) consistently outperform those using fewer.
• Update every major release. Stale screenshots signal an abandoned app. Fresh screenshots boost both conversion and editorial pick chances.
• Test, don't guess. Apple's Product Page Optimization and Google's Store Listing Experiments are free. Use them.
