Dovetail Joint Calculator
Calculate perfect dovetail joint dimensions. Determine angles, spacing, pin/tail proportions for woodworking projects with precision.
Step 1: Board Dimensions
Understanding Board Thickness
Board thickness affects dovetail proportions. Thicker boards allow for larger tails, while thinner boards require smaller, more delicate joints.
Step 2: Dovetail Specifications

About Dovetail Angles
Softer woods need steeper angles (1:6) for strength. Hardwoods can use shallower angles (1:8) for a more delicate appearance. Traditional joinery often uses 1:8 ratio.

Joint Proportion Analysis
Dovetail Formula
Tail Width = (Board Width – (Pins × Pin Width)) / Number of Tails
The dovetail joint proportions are calculated based on board width, number of tails, and desired pin-to-tail ratio for optimal strength and aesthetics.
