Aspect Ratio Calculator
Reduce width and height to a clean ratio and scale to a target width.
How it works
Ratio = width:height reduced by GCD.If target width is set, height = target width ÷ (width/height).
Worked example
4500 × 5400 → 5:6.At 12 in wide → height = 14.4 in.

| 2:1 / 2.5:1 | Mug and tumbler wraps (brand-specific) |
