About this Tool
Reduce dimensions to a ratio and calculate a matching width or height for a new size.
How it works
Reduces width and height by their greatest common divisor and preserves that ratio while scaling.

Convert a 1920×1080 source into the matching height for a 1280-pixel export.
Use results as a practical aid, and verify important decisions against your own source data and qualified guidance.
