Post the wrong size image to social media and you'll often see it awkwardly cropped, stretched, or compressed into mush by the platform itself. Here are the dimensions that actually work well on the three biggest platforms right now.
- Square post: 1080 x 1080 px
- Portrait post: 1080 x 1350 px (this gets more screen space in the feed)
- Landscape post: 1080 x 566 px
- Story / Reel: 1080 x 1920 px
- Profile picture: 320 x 320 px
- Shared image post: 1200 x 630 px
- Cover photo: 820 x 312 px (desktop) — Facebook crops differently on mobile, so keep key content centered
- Profile picture: 170 x 170 px
- Event image: 1920 x 1005 px
- Shared image post: 1200 x 627 px
- Cover banner: 1584 x 396 px
- Profile picture: 400 x 400 px
- Company logo: 300 x 300 px
Why Getting This Right Matters
When you upload an image at the wrong dimensions, most platforms will auto-crop or auto-compress it — often cutting off important parts of the image or degrading quality in ways you didn't intend. Resizing to the platform's actual dimensions before uploading gives you full control over composition and keeps quality sharp.
A Simple Rule of Thumb
When in doubt, square (1:1) and portrait (4:5) formats tend to perform well across most platforms and take up more visual space in feeds compared to landscape images. If you're posting the same image across multiple platforms, resizing individually for each one — rather than using one size everywhere — will always look sharper.
