Enter the scale length (in) into the Fret Distance Calculator. The calculator will evaluate and display the Fret Distance. 

Fret Distance Formula

The following formula is used to calculate the Fret Distance. 

Dfret = SL / 17.817

  • Where Dfret is the Fret Distance (in)
  • SL is the scale length (in) 

How to Calculate Fret Distance?

The following example problems outline how to calculate Fret Distance.

Example Problem #1:

  1. First, determine the scale length (in). 
    • The scale length (in) is given as: 30.5.
  2. Finally, calculate the Fret Distance using the equation above: 

Dfret = SL / 17.817

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

Dfret = 30.5 / 17.817 = 1.712 (in)

Example Problem #2: 

For this problem, the variables needed are provided below:

scale length (in) = 70.2

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Dfret = SL / 17.817 = ?
