Gibson Calculator
If you’re a guitar builder, luthier, or enthusiast, accurately placing frets is essential for proper intonation and playability. The Gibson Calculator helps you determine the exact distance of a fret from the nut, distance from the bridge, and fret spacing based on your guitar’s scale length.
This tool works for standard Gibson-style guitars or any guitar with a known scale length, making fretboard setup faster, easier, and precise.
What Is the Gibson Calculator?
The Gibson Calculator is an online tool that computes fret positions using the standard 12-tone equal temperament formula, which divides the scale length logarithmically to place frets accurately.
Key outputs include:
- Distance from Nut: How far the selected fret is from the nut.
- Distance from Bridge: How far the selected fret is from the bridge.
- Fret Spacing: The distance between the selected fret and the previous fret.
It supports frets 0–24 and any scale length in inches.
How to Use the Calculator
Step 1: Enter Scale Length
Input your guitar’s scale length in inches. For example:
- Gibson Les Paul: 24.75″
- Fender Stratocaster: 25.5″
Step 2: Enter Fret Number
Choose the fret number (0–24) you want to calculate.
- Fret 0 = open string
- Fret 12 = octave
Step 3: Click Calculate
The calculator will instantly display:
- Distance from nut
- Distance from bridge
- Spacing from previous fret
You can reset the inputs to calculate other frets quickly.
Example Calculation
Example 1: Gibson Les Paul
- Scale Length: 24.75″
- Fret Number: 5
Results:
- Distance from Nut: 5.514″
- Distance from Bridge: 19.236″
- Fret Spacing: 1.041″
Example 2: Fender Stratocaster
- Scale Length: 25.5″
- Fret Number: 12
Results:
- Distance from Nut: 12.750″
- Distance from Bridge: 12.750″
- Fret Spacing: 0.638″
These results ensure perfect intonation when placing frets or building your own guitar.

Frequently Asked Questions (FAQs)
- What is a scale length?
Scale length is the vibrating length of a string, measured from the nut to the bridge saddle. - Can I calculate all 24 frets?
Yes, the calculator supports frets 0 through 24. - Do I need to enter inches or centimeters?
This calculator uses inches. You can convert from cm if needed. - Is this tool only for Gibson guitars?
No, it works for any guitar using a known scale length. - Why is fret spacing smaller at higher frets?
Fret distances shrink as you move up the neck due to logarithmic division of the scale length. - Can I use this for bass guitars?
Yes, any stringed instrument with a fixed scale length works. - Do I need special knowledge to use it?
No, the calculator is beginner-friendly. Just enter scale length and fret number. - What is fret spacing?
Fret spacing is the distance between the selected fret and the previous fret. - Can I reset the inputs?
Yes, use the Reset button to start over. - Is this calculator suitable for custom guitars?
Absolutely. Any scale length and fret number can be calculated. - Does it account for intonation adjustments?
This calculates theoretical fret positions. Fine-tuning may be needed at the saddle. - Can I use it for multiple frets at once?
Currently, it calculates one fret at a time. - Does the calculator include fretboard radius?
No, it calculates only fret distances along the string. - How precise are the results?
Distances are calculated to three decimal places for high accuracy. - Is it mobile-friendly?
Yes, it works on desktops, tablets, and smartphones.
Conclusion
The Gibson Calculator is an essential tool for guitar enthusiasts and luthiers. It simplifies fret placement, ensures accurate intonation, and saves hours of manual calculation. Whether building a new guitar, refretting, or customizing a neck, this tool is precise, fast, and easy to use.
