How to Use This Calculator

Enter Scale Length, Fret Number, and Temperament.
Set String Compensation.
Review the Distance from Nut (mm) result.
Use Distance from Bridge (mm) and Fret Spacing (mm) to inform your decision.
Use the chart to visualize the results and explore different scenarios by adjusting inputs.

How the result changes with Scale Length

Scale Length: Scale length in mm (e.g., 648mm = 25.5in Fender, 629mm = 24.75in Gibson).
Fret Number: Which fret to calculate the position for (1-24).
Temperament: 1=Equal temperament (standard), 2=True temperament (micro-adjusted).
String Compensation: Additional saddle compensation in mm for string stiffness.
