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:

- First, determine the number of frets.
- The number of frets is given as: 12.

- Next, determine the fret to fret distance (in).
- The fret to fret distance (in) is provided as: 1.5.

- 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

Test your knowledge using the equation and check your answer with the calculator..

SCL = #F * FTFD** = ?**
