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.

Calkulon makes complex calculations simple — built for students and everyday problem-solvers.

Pormula

▾

f(x)Scale by width: New Height = Original Height × (New Width ÷ Original Width)

Paano Aspect Ratio Calculator

▾

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)
