About these sizes
The aspect ratio is the width-to-height proportion reduced to its lowest whole numbers, so 1920×1080 becomes 16:9. Matching a platform's recommended ratio stops your image being cropped or letterboxed.
Upload at the largest listed size for crisp results; platforms downscale better than they upscale. Specs change from time to time, so confirm against the platform's own help pages for anything critical. The calculator runs in your browser.

How it works
1920×1080 reduces to 16:9. Matching a platform’s recommended ratio avoids cropping or letterboxing; platforms downscale better than they upscale.
ratio = width : height, reduced by the GCD
Understanding your result
Matching a platforms recommended size and ratio is what keeps your image from being cropped or letterboxed. Pick the ratio first, then the pixel dimensions, and remember platforms downscale cleanly but upscale poorly, so start larger than the target rather than smaller and let the platform shrink it.
Example
1080×1080 is a 1:1 square.

Frequently asked questions
How is the aspect ratio calculated?
The width and height are reduced to their lowest whole-number terms using the greatest common divisor — so 1920×1080 becomes 16:9.
Why does matching the ratio matter?
Uploading at a platform’s recommended ratio stops your image being cropped or letterboxed. Upload at the largest listed size, since platforms downscale better than they upscale.
Are these sizes always up to date?
Platforms change their specs from time to time. These are current, widely-used recommendations, but confirm against the platform’s own help pages for anything critical.
