Story Image Sizes Across Platforms: Instagram, Facebook, Snapchat, and TikTok Compared
Vertical full-screen content has become the default format across social media, but not every platform handles it identically. While Instagram and Facebook stories share the same 1080×1920 base, Snapchat and TikTok have their own aspect ratio preferences and safe zones for UI overlays. If you repurpose vertical content across multiple platforms — which most creators and brands do — understanding these differences prevents the frustrating experience of text getting hidden behind usernames, buttons, or swipe-up prompts. This comparison shows you exactly where each platform places its UI chrome so you can design once and adapt efficiently.

Instagram Story
1080 × 1920px
Stories are full-screen vertical assets. Leave ~14% padding at top and bottom for Instagram's UI chrome (username, reply bar).
Facebook Story
1080 × 1920px
Full-screen vertical format shared with Instagram Stories. Same safe-area rules apply.
Snapchat Story
1080 × 1920px
Full-screen vertical stories. Same format as ads but for organic content.
TikTok Video Cover
1080 × 1920px
Video covers display full in the For You feed but get cropped to roughly 3:4 in profile grid view.
Frequently asked questions
Are Instagram and Snapchat story sizes the same?
Both use 1080×1920 (9:16), so the base dimensions match. However, Snapchat's UI overlays (username, time, temperature) sit in different positions than Instagram's. The safe zone for text is slightly smaller on Snapchat. If you design for the tighter constraints, your content works on both.
What size is a TikTok cover image?
TikTok video covers are 1080×1920 (9:16), the same base dimensions as Instagram and Facebook stories. The cover image is what appears on your profile grid and in search results, so it needs to be visually clear even at small thumbnail sizes.
Can I post the same vertical video to all four platforms?
Yes, if you shoot at 1080×1920 you have the right base dimensions for all four. The main differences are safe zones — each platform places its UI elements (username, like buttons, captions) in slightly different spots. Avoid placing critical text in the top 15% or bottom 20% of the frame and you will be safe across all platforms.
