Image Aspect Ratio Calculator

Simplify image dimensions and calculate matching widths or heights without uploading an image.

Enter valid positive values to calculate a result.

Private by design. This tool runs in your browser. Your input is not sent to FollowReach or stored.

Before you start

  • • Resize planned visual dimensions while preserving their ratio.
  • • Use the result as a planning reference and verify current platform requirements before publishing.

How to use it

  1. 1. Enter only the information you want to evaluate.
  2. 2. Review any validation guidance, then calculate or generate the result.
  3. 3. Copy the useful output or reset the tool when finished.

How it works

Width and height are divided by their greatest common divisor. Optional matching dimensions preserve the same decimal ratio.

Limitations

  • • The result does not certify platform-specific image approval.
  • • Results use only the values entered in this browser and do not include live platform data.
