Dovetail Angle Calculator
The free Dovetail Angle Calculator answers one question: Convert dovetail ratios to degrees. Enter your numbers in inches or millimeters and the result updates instantly in your browser, with no sign-up and no app to install. Use it on your phone at the bench, then copy or print the result for your cut list.
Common rule: 1:6 for softwood, 1:8 for hardwood. Steeper ratios look bolder, shallower ones are stronger in short grain.
