Calculate Fret Distance Zero Fret
Calculating fret distance, especially for a zero fret, is crucial for setting up and maintaining your guitar or bass. It ensures accurate intonation and playability.
- Enter the string scale length in millimeters.
- Select the fret number.
- Click ‘Calculate’.
The formula for calculating fret distance is:
Fret Distance = (String Scale Length * (Fret Number / 12)) - (String Scale Length / 12)
The calculation is done in millimeters.
| String Scale Length (mm) | Fret Number | Fret Distance (mm) |
|---|---|---|
| 650 | 5 | 54.17 |
| 650 | 12 | 108.33 |
| 650 | 20 | 183.33 |
| Fret Number | Fret Distance (mm) for 650mm scale | Fret Distance (mm) for 628mm scale |
|---|---|---|
| 0 | 0 | 0 |
| 1 | 54.17 | 52.33 |
| 2 | 108.33 | 104.67 |
- Always measure from the nut to the fret, not the center of the fret.
- Use a precision ruler or calipers for accurate measurements.
- Regularly check and adjust your fret distances for optimal performance.
What is a zero fret?
A zero fret is a fret located at the nut on some guitars and basses. It helps to improve intonation and playability.
Why is fret distance important?
Accurate fret distance ensures that each fret is properly intonated, allowing for clear and in-tune playing.
