Golden Ratio Calculator

Create larger and smaller proportional companions from any positive measurement.

What this tool does

Explore one proportional relationship without treating it as a rule.

The calculator multiplies and divides a positive value by the golden ratio, approximately 1.618.

The outputs are optional design references rather than evidence that a composition will be inherently better.

Use the tool

Calculate golden-ratio companions
