About this tool
A 1080 by 1080 square post takes up more of a phone screen in the Facebook feed than a landscape image does, which is why many pages switch to square for mobile audiences. It is also the size to use when you cross-post the same graphic to Instagram. The page crops to that square, which takes up more vertical space in a phone feed than the 1200 x 630 landscape post.
How to use this tool
- Drop in the imageAdd a product photo, quote or announcement; the square preset is set.

- Post to Facebook and InstagramDownload once and use the same file on both platforms.
Square for mobile feeds and cross-posting
Most Facebook browsing happens on phones, where a square image is roughly 50% taller on screen than a 1.91:1 landscape one. If you publish the same creative to Instagram and Facebook, a square master avoids two separate crops. Keep a consistent margin so the image still works if Facebook shows it in a multi-photo layout.
