Guitar Fret Distance Calculator
Calculate precise fret positions and distances for guitar construction and setup
About this calculator
The Guitar Fret Distance Calculator determines the precise positioning of frets on a guitar neck using mathematical formulas based on the 12-tone equal temperament system. This tool is essential for luthiers, guitar builders, and repair technicians who need accurate measurements for constructing or setting up guitar necks. By calculating the exact distance from the nut to each fret, it ensures proper intonation and playability across all frets and strings.
How to use
Enter your guitar's scale length (distance from nut to bridge saddle) into the calculator. The tool will automatically calculate and display the precise distance from the nut to each fret position. Use these measurements when marking fret positions during guitar construction or when checking existing fret placement during setup and repair work.
Frequently asked questions
What is scale length and how do I measure it?
Scale length is the vibrating length of the string, measured from the nut to the bridge saddle. Common lengths are 24.75" (Gibson) and 25.5" (Fender).
Why are fret distances not evenly spaced?
Frets follow a logarithmic pattern based on the 12th root of 2, creating progressively smaller intervals as you move up the neck for proper pitch relationships.
Can I use this calculator for bass guitars or other instruments?
Yes, this calculator works for any fretted string instrument. Simply input the correct scale length for your specific instrument to get accurate fret positions.
