1:1 Aspect Ratio Calculator
Use this 1:1 aspect ratio calculator when you need a perfect square. A 1:1 image has the same width and height, making it simple to use for profile pictures, icons, product thumbnails, album art and square social posts. Enter either dimension and use the same value for the other side.

Best uses for square images
The 1:1 ratio is the easiest aspect ratio to calculate because both sides are equal. It remains useful because square images crop predictably and work well in grids, avatars and product listings.
A square image is not always the most attention-grabbing format in a feed, but it is reliable. It is also a good master crop when the same image must work across profile pictures, thumbnails and circular masks, because the subject can be centered with equal room on every side.
A square-ratio page earns its place by focusing on predictability. 1:1 images are easy to crop, easy to center and easy to reuse in grids. They work well for avatars, app icons, product thumbnails, album art and square social posts because the subject sits in the center with equal space around every edge.
Square canvases also suit circular masks. Many platforms display profile images as circles but ask for a square source, so keeping the face, logo or product centered stops it being clipped when the corners are rounded. That is a genuinely different job from 4:5 feed images or 9:16 vertical video.
