How to use Golden Ratio Calculator

Type in one known measurement and the calculator returns the corresponding golden-ratio larger and smaller values using phi.

Frequently asked questions

What is the golden ratio?

Phi (φ) ≈ 1.618, the ratio where a+b is to a as a is to b. It appears in art, design and nature.

How is it calculated from one number?

Enter one length and the calculator multiplies or divides by 1.618 to give the longer and shorter golden segments.

Where is the golden ratio used?

In layout design, typography, logo proportions, photography composition and architecture for visually pleasing balance.
