Both calculators run independently — change the inputs on either side to compare results.
Dovetail Angle Calculator
Find the traditional dovetail joint angle for softwood or hardwood based on standard woodworking practice. Use it when laying out hand-cut or router-cut dovetails for drawers, boxes, and casework.
Dovetail Angle
8 degrees
At 14°, you have the steeper slope used for softwoods like pine, where longer fibers tolerate a 1:6-style angle that boosts mechanical grip in weaker grain.
Traditional dovetail slope ratios: softwood is cut at 1:6 (~9.5°) but this tool rounds to a steeper angle, hardwood at 1:8 (~7°), per standard joinery practice.
Mortise and Tenon Calculator
Calculates tenon thickness as two-thirds of the rail thickness, rounded to the nearest 1/16 inch — the classic rule for strong mortise-and-tenon joints. Use it when laying out frame-and-panel furniture or door construction.
