This cheatsheet collects every official Snapchat image and video dimension in one filterable table so you never guess a canvas size again. It covers Snaps, Stories, Spotlight, Discover tiles, and the full range of ad placements — each with the recommended pixel size, aspect ratio and any format caveat.
How it works
Snapchat is a full-screen vertical platform, so almost every surface uses the 9:16 ratio at 1080×1920 px. Media that does not match gets letterboxed with black bars or centre-cropped. The tool groups each placement by category, lists the width × height in pixels, and derives the simplified aspect ratio by dividing both sides by their greatest common divisor — so 1080×1920 reduces to 9:16.
A few specialised assets break the 9:16 mould: Geofilters use a taller 1080×2340 transparent PNG with strict edge-only design rules and a small file-size cap, while Discover and tile previews have their own crops. The cheatsheet flags those exceptions so you do not apply the wrong template.
Tips
- Design at the largest listed size, then scale down — upscaling a small image always looks worse than downscaling a large one.
- For video, export H.264 MP4 with AAC audio; Snapchat transcodes everything, so a clean 1080p master is the best quality-to-size trade-off.
- Keep text and logos out of the top ~150 px and bottom ~150 px of full-screen Snaps, where Snapchat overlays its own UI.
- Geofilters must be a transparent PNG under 300 KB with the centre kept clear — design only along the top and bottom edges.
