iMessage Image Size Cheat Sheet 2026

Q: What size are iMessage stickers?

iMessage stickers come in three sizes: Small (300x300), Medium (408x408), and Large (618x618). All stickers in a pack must use the same size class. PNG, APNG, and GIF formats are supported.

Q: What is the best iMessage sticker size?

Medium (408x408) is the most popular choice for iMessage sticker packs. It provides a good balance between detail and grid visibility. Use Large (618x618) only if your stickers have fine detail that needs the extra resolution.

Q: Can iMessage stickers be animated?

Yes. iMessage supports animated stickers in APNG and GIF formats. APNG is preferred because it supports better color depth and smaller file sizes than GIF. Keep animations under 500 KB per sticker.

Q: How do I create an iMessage sticker pack?

Prepare your sticker images at the correct size using FastEdit, then use Xcode to create a Sticker Pack Application. Add your exported images to the Sticker Pack folder in Xcode and submit to the App Store.

iMessage stickers come in three size classes: Small (300x300), Medium (408x408), and Large (618x618), defined by Apple for the Messages app. Each sticker in a pack must use the same size class. FastEdit helps you resize and export images at the exact dimensions Apple requires so your stickers render perfectly on every device.
