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)
How to Calculate Digit Ratio?
The following example problems outline how to calculate Digit Ratio.
Example Problem #1:
- First, determine the length of your index finger (in).
- The length of your index finger (in) is given as: 2.125.
- Next, determine the length of your ring finger (in).
- The length of your ring finger (in) is provided as: 2.35.
- 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
Test your knowledge using the equation and check your answer with the calculator above.
DR = 2D / 4D = ?
