Enter the number of frets and the fret to fret distance (in) into the Scale Length Calculator. The calculator will evaluate the Scale Length.

## Scale Length Formula

The following two example problems outline the steps and information needed to calculate the Scale Length.

SCL = #F * FTFD

• Where SCL is the Scale Length (inches)
• #F is the number of frets
• FTFD is the fret to fret distance (in)

## How to Calculate Scale Length?

The following example problems outline how to calculate Scale Length.

Example Problem #1:

1. First, determine the number of frets.
• The number of frets is given as: 12.
2. Next, determine the fret to fret distance (in).
• The fret to fret distance (in) is provided as: 1.5.
3. Finally, calculate the Scale Length using the equation above:

SCL = #F * FTFD

The values provided above are inserted into the equation below and computed.

SCL = 12 * 1.5 = 18 (inches)

Example Problem #2:

For this problem, the variables required are provided below:

number of frets = 6

fret to fret distance (in) = 3
