How to Calculate Aspect Ratio Calc
What is Aspect Ratio Calc?
An aspect ratio calculator determines the proportional relationship between width and height, expressed as W:H. It lets you scale dimensions while preserving the original ratio to prevent distortion.
Formula
Step-by-Step Guide
- 1Aspect Ratio = Width : Height, simplified by dividing both by their GCD
- 2GCD (Greatest Common Divisor) found using the Euclidean algorithm
- 3Scale by width: New Height = Original Height × (New Width ÷ Original Width)
- 4Scale by height: New Width = Original Width × (New Height ÷ Original Height)
