Image Sizes

Facebook post size

1200 × 630 40:21

JPG or PNG

The Open Graph image. Also what X and LinkedIn use.

1200 × 630

Drop an image to check it Optional — the spec is above either way. Nothing is uploaded.

Cropped in your browser · your image is never uploaded

Local · link previews come from og:image, not an upload

A shared link uses 1200 × 630 — the Open Graph image. A photo you upload directly is better at 1080 × 1350, the same portrait ratio Instagram prefers, because it takes more vertical space in the feed.

How to use the facebook post size

1 Read the dimensions above. That is the whole answer if the spec is all you came for.

2 Drop your own image in to check it against the spec — size, aspect ratio and file weight are each checked separately.

3 Turn on the safe zone to see what gets cropped or covered, then download the cropped version at the exact size.

These are two different mechanisms and it is worth not confusing them. When you paste a link, Facebook fetches the page’s Open Graph image and shows it at roughly 1.91:1 — you control that by setting og:image on the page, not by uploading anything. When you upload a photo directly, you control the shape, and portrait works harder. The other thing to know is that Facebook caches Open Graph data aggressively, so changing a page’s image does not change the preview until the cache is refreshed through their Sharing Debugger.
