Enter the height of the flag and the width of the flag into the calculator to determine the flag aspect ratio.

## Flag Ratio Formula

The following equation is used to calculate the Flag Ratio.

FR = H/W
• Where FR is the flag ratio 1:X
• H is the height of the flag
• W is the width of the flag

To calculate the flag ratio, simply divide the height of the flag by it’s width.

## What is a Flag Ratio?

Definition:

A flag ratio measures the ratio of the dimensions of height to width of a flag.

## How to Calculate Flag Ratio?

Example Problem:

The following example outlines the steps and information needed to calculate a Flag Ratio.

First, determine the height of the flag. In this example, the height of the flag is 20 inches.

Next, determine the width of the flag. For this problem, the width is 40 inches.

Finally, calculate the flag ratio using the formula above:

FR = H/W

FR = 20/40

FR = .50 = 1:2
