2. Scale length = 25.5

3. Fret number = 12

5. Distance from nut = 12.75

Did this calculator solve your problem today?

The math behind it

distance from nut = scale length − scale length ÷ 2^(fret ÷ 12). The 12th fret is exactly halfway.

25.5" scale, fret 12 → 12.75" (halfway).

Why halfway at 12?

The 12th fret is one octave up — half the string length.
