Type the angle of your corner in degrees. For a standard 90° corner, enter 90 — Mitre will return 45°. For any other angle, enter the value and the correct miter is calculated instantly.
Select the number of sides for a regular polygon — triangle through dodecagon. The corner angle is calculated automatically, and the miter angle updates as you adjust the sides. Use the quick-select row for the most common shapes.
The large number is the miter angle to set on your saw. Below it, the complementary angle (90° minus the miter) is shown for saws that label their bevel the other way. Tap either number to copy it to your clipboard.
