Facebook Post Image Size

For photos in the Facebook feed, a 1080 × 1080 square or a 1080 × 1350 portrait (4:5) image is a safe choice; taller images are usually cropped in the feed. Link previews use a wide 1.91:1 image, typically 1200 × 630.

Format	Size (px)	Aspect ratio
Square	1080 × 1080	1:1
Portrait	1080 × 1350	4:5
Link preview	1200 × 630	≈ 1.9:1

Safe zone and tips

Upload at least 1080 px wide so the image stays sharp on high-density phone screens.
For shared links, the preview comes from the page’s og:image tag; 1200 × 630 is the usual size.
When you post several photos at once, Facebook arranges them in a collage and crops each one, so keep subjects centred.
Text-heavy images are hard to read on phones; keep text short and large.

Making a 1:1 image from a phone photo

A typical 12-megapixel phone photo is 4032 × 3024. The largest 1:1 area you can cut from it is 3024 × 3024 pixels: crop to that, then scale it down to 1080 × 1080. Cropping first and scaling second keeps everything in proportion.

Frequently asked questions

What is the best size for Facebook posts?

Use 1080 × 1080 (Square, 1:1), 1080 × 1350 (Portrait, 4:5), and 1200 × 630 (Link preview, ≈ 1.9:1). The first one is the safest default.

Which aspect ratio should Facebook posts use?

1:1, 4:5, and ≈ 1.9:1. Crop to the ratio first and then scale to the size in pixels, so nothing is stretched or cut off unexpectedly.

What size is a Facebook link preview image?

Use 1200 × 630 pixels, a 1.91:1 ratio, set in the page’s og:image tag. Much smaller images may be shown as a small thumbnail beside the link instead of a large preview.
