Enter the length of your index finger (in) and the length of your ring finger (in) into the Digit Ratio Calculator. The calculator will evaluate and display the Digit Ratio.

## Digit Ratio Formula

The following formula is used to calculate the Digit Ratio.

DR = 2D / 4D
• Where DR is the Digit Ratio ( )
• 2D is the length of your index finger (in)
• 4D is the length of your ring finger (in)

To calculate the digit ratio, divide the length of your index finger by the length of your ring finger.

## How to Calculate Digit Ratio?

The following example problems outline how to calculate Digit Ratio.

Example Problem #1:

1. First, determine the length of your index finger (in).
• The length of your index finger (in) is given as: 2.125.
2. Next, determine the length of your ring finger (in).
• The length of your ring finger (in) is provided as: 2.35.
3. Finally, calculate the Digit Ratio using the equation above:

DR = 2D / 4D

The values given above are inserted into the equation below and the solution is calculated:

DR = 2.125 / 2.35 = .904

Example Problem #2:

For this problem, the variables required are provided below:

length of your index finger (in) = 2.5

length of your ring finger (in) = 3
