Neck Angle Calculator
Calculate the set-neck angle needed for a glued-neck build, from scale length, neck/body joint distance, fretboard thickness, action, and target bridge height.
| Neck angle | 1.48° |
|---|---|
| Rise per 100mm run | 2.58 mm |
| Rise per 4in run | 2.626 in |
This angle is measured from the neck/body joint position you entered above — not the nut, not the heel. Set your neck-angle jig or protractor reference to that same point, or the cut will be wrong.
First-order geometric estimate — a starting point for a check jig or dry-fit, not a final cutting instruction. Doesn’t account for fretboard radius/compound taper or truss-rod relief. Confirm with a straightedge and strung-up test fit before final routing.
