Dovetail Calculator
Lay out equal dovetail tails from board width, tail count and chosen pin widths.
Results
Equal tail width
—
Full pins
—
Edge half-pins
—
Dovetail slope angle
—
Use the result as a planning estimate and verify project-specific measurements, manufacturer information and local requirements where relevant.
How it works
The calculator subtracts the chosen edge and full-pin widths from the board width, divides the remainder equally among the tails, and converts the 1:n slope ratio to an angle.
tail width = remaining board width ÷ number of tails
