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.
