The 1:1 aspect ratio is a perfect square – width and height are equal. It is widely used for social media profile pictures, Instagram posts, and product images.
Because it is symmetric, 1:1 works well in grid layouts and feeds, providing a consistent, balanced appearance.
If you're creating content for Instagram or an e‑commerce site, square images often perform best.
These are typical square pixel dimensions.

A 1:1 image has equal width and height. Common sizes are 1080x1080, 720x720, and 400x400 pixels.
Instagram, Facebook, Twitter, and many e‑commerce sites use 1:1 for profile pictures and grid layouts.
Since width equals height, you only need to decide one dimension. The calculator can scale it to any square size automatically.
