## Introduction: Golden Rectangle- How to Make One

Many of you will have absolutely no idea what a golden rectangle is- I aim to change that in this Instructable.

## Step 1: What Is a Golden Rectangle?

A golden rectangle is not made of gold. Sorry. It is called that because it is ‘perfect’. It is the ideal rectangle shape that is pleasing to look at. Multiple artworks were based around it; the Mona Lisa, the Parthenon, and the Sacrament of the last supper, to name a few. Why not incorporate the golden rectangle into your paintings or furniture designs?

Note: the golden rectangle is sometimes called the divine proportion or the golden ratio.

## Step 2: Calculating the Size of a Golden Rectangle

The ratio for the golden rectangle is 1:1.618. Where 1 is the shorter side and 1.618 is the longer side. If you were to do this with a short side that was 1cm in length than the long side would simply be 1.618cm in length. But if you wanted to have one where the short side was 10cm then you would, to find the long side, multiply 10 by 1.618, which gives you 16.18cm.

Note: The golden ratio is not exactly 1:1.618, in fact it is 1: (1+ square root of 5) divided by 2. This gives you ‘Phi’- a Greek letter - φ . This letter comes from a man called Phidias, who was one of the designers of the Parthenon in Athens.
