This cheatsheet collects every official Facebook image and video dimension in one filterable table so you never have to guess a canvas size again. It covers feed posts, Stories, Reels, profile and cover art, and the full range of ad placements, each with the recommended pixel size, aspect ratio and any format caveat.
How it works
Facebook publishes recommended dimensions per surface, and uploading at those exact sizes prevents the platform’s automatic re-cropping and re-encoding from softening your image. The tool groups each placement by category and lists the width × height in pixels alongside the simplified aspect ratio. Aspect ratio is derived by dividing both sides by their greatest common divisor — for example 1080×1920 reduces to 9:16.
Vertical surfaces (Stories, Reels) use 9:16, square feed media uses 1:1, and link previews use roughly 1.91:1. Matching these means Facebook displays your full frame rather than centre-cropping it.
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; Facebook accepts up to 4K but transcodes everything, so a clean 1080p master is usually the best quality-to-size trade-off.
- Keep text and logos away from the outer 14% of Stories and Reels frames, where Facebook overlays its own UI.
