Aspect ratio calculator

Enter one dimension and get the other for common video ratios: widescreen, vertical, square, and ultrawide. Useful when sizing canvases, exports, or thumbnails.

Pick a preset like 16:9 or 9:16, or type a custom ratio. The preview box updates so you can see the shape before you open your editor.

Glisio exports widescreen, vertical, and square from one Mac recording when you are ready to publish.
