Facebook Post Image Sizes & Aspect Ratio Guidelines
Meta does not mandate a single universal pixel resolution for organic Facebook feed photos. Instead, three working aspect ratios are widely recognized across creators and digital marketers. Understanding how aspect ratios and resolutions interact helps ensure your photos appear sharp and unobstructed:
| Format Style | Recommended Dimensions | Aspect Ratio | Best Use Case |
|---|---|---|---|
| Portrait Post | 1080 x 1350 px | 4:5 | Mobile feed posts, portraits, infographics, and storytelling visuals. |
| Square Post | 1080 x 1080 px | 1:1 | Universal multi-platform sharing, product photos, and quote cards. |
| Landscape Post | 1200 x 630 px | 1.91:1 | Widescreen landscapes, event promotions, and article link previews. |
Aspect Ratio vs. Resolution: If your photo has the correct aspect ratio (e.g. 2160 x 2700 px is identical to 4:5), Facebook will scale it down cleanly without cropping. If your image requires cropping or framing adjustments, use our dedicated Facebook Post Image Resize Tool.

Frequently Asked Questions
What size should a Facebook post image be?
Facebook does not enforce one universal pixel size for organic feed posts, but creators and marketers commonly use three practical working formats: Portrait 1080 x 1350 px (4:5 aspect ratio, best for mobile feeds), Square 1080 x 1080 px (1:1 ratio, universal desktop and mobile display), and Landscape 1200 x 630 px (~1.91:1 ratio, standard for widescreen visuals and link previews).
Can I check if my Facebook post image is 1080 x 1350?
Yes. Upload your image or enter your pixel width and height into this tool. The checker immediately evaluates whether your image matches 1080 x 1350 px exactly, shares the same 4:5 aspect ratio at a different resolution, or requires cropping.
Can I check square and landscape Facebook post sizes too?
Yes. In addition to 4:5 portrait, the tool simultaneously evaluates your image against the 1080 x 1080 (1:1) square format and the 1200 x 630 (1.91:1) landscape format, showing exact status badges and crop previews for each.
Can this tool check the aspect ratio of my Facebook post image?
Yes. The checker calculates your exact aspect ratio from your image dimensions and compares it against common Facebook post formats within a tolerance margin to determine if your image will display naturally or require cropping.
What should I do if my Facebook post image does not match the recommended size?
If your image does not match the desired aspect ratio or pixel target, you can click the direct link to our Facebook Post Image Resize Tool. There you can crop, reposition, zoom, and export your picture in portrait, square, or landscape format.
