Facebook Post Image Size
For a link you share, Facebook pulls a 1200×630 px (1.91:1) preview image. For a plain photo post, upload 1200×1200 px (square) for the sharpest feed display. Facebook caps display width around 2048 px.

Link shares: 1200×630 (1.91:1)
When you paste a URL, Facebook shows the page's Open Graph image at 1200×630 px. Below 600×315 it falls back to a tiny thumbnail, so always set a full-size OG image. Keep text away from the edges — Facebook overlays the link title and domain along the bottom.
Photo posts: go square or portrait
A single uploaded photo displays largest at 1200×1200 (1:1) or 1200×1500 (4:5). Portrait grabs more vertical space on mobile feeds. Facebook downscales anything wider than about 2048 px, so there's no benefit to uploading larger.
