How to Use

1. Resize Dimensions: Enter a known width or height in the bottom inputs. As long as the ratio is set, the other dimension will calculate automatically.
2. Find an Aspect Ratio: Enter your exact pixel Width and Height, then click "Calculate Ratio from Width/Height" to find its simplified aspect ratio.
3. Use Presets: Click on any of the common presets (like 16:9 or 1:1) to quickly set the ratio and re-calculate your dimensions based on your current width.
4. The visual preview area shows a scaled representation of the current aspect ratio box.
