  2. The simplified aspect ratio and decimal ratio are shown automatically.
  3. Enter a "new width" to automatically calculate the height at the same ratio.

FAQ

How is the aspect ratio simplified?

It's reduced to the simplest whole-number ratio by dividing both the width and height by their greatest common divisor (only when both are whole numbers).

Can I enter decimal widths and heights?

Yes, decimals work for the calculation, but the simplified ratio display only appears when both are whole numbers.

Can I work backward from a new height to find the width?

The current version only supports calculating height from a new width.
