Facebook image size
Facebook favours square images because they fill the most space in the feed and in Marketplace listings on mobile. A 1,200 × 1,200 px square is a safe, high-quality choice that stays sharp everywhere. This preset outputs exactly that, so your listing or post looks crisp on every screen.
| Use | Value |
|---|---|
| Marketplace listing | 1,200 × 1,200 px (square) |
| Minimum shortest side | 500 px |
| Feed post | 1,200 × 1,200 or 1,080 × 1,080 px |
| Aspect ratio | 1:1 (square) |
| Format | JPG or PNG |
How to resize your image for Facebook
- Drop your photo onto the box above (or click to browse).
- Keep the Facebook 1200 × 1200 preset selected.
- Leave the format on JPG for the smallest file, or switch to PNG if you need transparency.
- Click Resize image and download the result.
Heads up: a square works across Marketplace and the feed, but Facebook Stories need a tall 9:16 image instead. If you're posting to Stories, resize with the Resize for Instagram tool, which includes a Stories preset.
Frequently asked questions
What size should a Facebook Marketplace image be?
A 1,200 × 1,200 px square displays well for Marketplace listings. The minimum recommended is 500 px on the shortest side, but a larger square keeps your product sharp on every device.
What size should a Facebook feed post be?
A 1,200 × 1,200 px square works well, and 1,080 × 1,080 px is also fine. A square fills more of the feed on mobile than a landscape or portrait image.
