Which ratio should you deliver?
Facebook rows on this page come from https://www.facebook.com/business/ads-guide. Last verified 2026-10-06. If a placement is missing, we did not have an official URL we were willing to cite.

Feed image (square): 1080×1080 (1:1). Meta Ads Guide lists 1:1 as a primary feed image ratio. Stories: 1080×1920 (9:16). Meta Ads Guide lists 9:16 for Stories placements.
Convert from a 16:9 master
Most cameras and desktop editors still start at 16:9. To reach 9:16, crop 607×1080 or pad 1920×3414 from a 1920×1080 source.
Open any table row in the calculator to set the width or the height in pixels. That is faster than retyping a cheat sheet.
What this page will not claim
Safe-zone UI chrome, bitrate caps and file-type limits change often. We list ratio and pixel size only when the cited help page states them.
Ads placements can differ from organic placements. The Meta and TikTok rows used here are the public ads/help specs, labelled as such.
Notes that apply only to Facebook Aspect Ratio
Meta’s ads guide is the cited source for feed and Stories-style frames. Organic Facebook posts can still display 1:1 and 9:16 well; we do not list every historical feed width that vanished from the public guide.
A 1:1 feed still plus a 9:16 Story is two converts from one 16:9 master. Keep the landscape original; do not overwrite it with the square crop.
Choose the Facebook aspect ratio per placement. A square 1:1 still sits cleanly in the feed. A Story wants 9:16 and should be its own file. Keep the 16:9 original, crop the feed version from the centre, and cut the Story taller only after the face is in the middle of the frame.
Frequently asked questions
Where do these sizes come from?
Only official help or ads-spec URLs listed in Sources.
What is last verified?
The date we last checked that URL. It is not a promise the vendor will not change the spec tomorrow.
How do I convert my existing file?
Use crop or pad from the 16:9 example, or open the converter.
Why is a size missing?
We omitted it rather than invent a pixel pair.
