Formula: distance = scale − scale ÷ 2^(fret ÷ 12)

Step-by-step with your numbers:

1. Values used:

2. Scale length = 25.5

3. Fret number = 12

5. Distance from nut = 12.75

Find where to place a fret along a guitar's scale length.

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.
