How it works

## How it works

The golden ratio, phi, is **(1 + square root of 5) / 2, about 1.618**. If a length is the shorter side, the longer side is that length times 1.618. If it is the longer side, the shorter side is that length divided by 1.618.

Example: a card 10 inches wide on its shorter side would be 10 x 1.618 = 16.18 inches long. A 1,200-pixel page split into golden parts gives a 741.6 pixel main column and a 458.4 pixel sidebar.

FAQ

## About this calculator

**What is the golden ratio?**

About 1.618. Two lengths are in the golden ratio when the longer divided by the shorter equals the total divided by the longer.

**Where is it used?**

Layouts, logos, photo crops and furniture proportions. A 1.618 rectangle is a common starting point in design.

**Does the unit matter?**

No. Inches, pixels or centimeters all work, and the answer is in the same unit.

**Is anything saved?**

No. The math runs in your browser and nothing you enter is sent to us.
