The online Golden Rectangle Calculator is used to calculate the golden rectangle based on the length of a single side.

In geometry, a golden rectangle is one whose side lengths are in the golden ratio (approximately 1:1.618).

A golden rectangle (interior golden rectangle) with longer side *a* and shorter side *b*, when placed adjacent to a square with sides of length *a*, will result in a new golden rectangle (outer golden rectangle) with longer side *a + b* and shorter side *a* (see image above).
