Fret Position Precision Calculator
Sauce Position Precision Calculator
When building a guitar from scratch, precise fret placement is critical. This calculator uses the standard 12th root of 2 formula to generate exact fret-to-nut distances for any scale length — accurate to fractions of a millimeter, with CSV export for your build plans.

Harmonic Node Positions
Where natural harmonics fall on the string for the same scale length — useful for intonation reference, fret placement sanity checks, and finding sweet spots. The first node of each harmonic is at scale ÷ n from the nut; nodes repeat at every multiple of that distance.
