Calculated result

15.4375 × 29 in per door

2 doors · overlay fit

Center gap: 0.125 in

Shaker stiles: 2 × 29 in per door

Shaker rails: 2 × 11.6875 in per door

Visible panel opening reference: 10.9375 × 24.5 in

1. Overlay finished height = 28 + 2 × 0.5 = 29 in.
2. Pair width = (31 − 0.125) ÷ 2 = 15.4375 in per door.
3. Rail cut reference = 15.4375 − 2 × 2.25 + 2 × 0.375 = 11.6875 in.

Door sizing and Shaker part lengths are planning dimensions. Verify hinge overlays/reveals, actual joinery geometry, groove depth and panel expansion against the hardware and tooling before cutting production parts.
