Frequently asked questions

What size is a 1:1 Instagram post?

The recommended size is 1080×1080 pixels. Instagram will accept larger squares and downscale them, but keep the sides equal to stay perfectly square.

Why do social platforms use 1:1?

Squares occupy screen space efficiently in a scrolling feed and work identically in portrait or landscape device orientations, so the format became the feed standard.

How do I convert a landscape photo to 1:1?

Crop the longest side down to match the shorter side. Use our calculator to preview what the resulting square covers before cropping.
