Miter Angle Calculator
Result
Miter Angle Calculator Calculate miter angle for polygon frames, corner joints, and compound miters. — free online calculator.
Formula
- Miter Angle Calculator calculates its result from Periods, Angle, Slope, Turn. It uses the formula Polygon: miter = 90 − 180/n; Corner: miter = angle/2; Compound: tan(miter) = tan(slope) × cos(turn). Change any input to recalculate the result instantly.
- The main inputs are Type, Number of Sides, Corner Angle, Slope Angle, Turn Angle. Enter them in the units and format shown in the calculator.
- Keep measurements and project assumptions consistent before comparing or combining values.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Miter Angle
- Type: polygon
- Number of Sides: 6
- Corner Angle: 90
- Slope Angle: 45
- Turn Angle: 45
Using Periods = 2, Angle = 3, Slope = 4, Turn = 5, the calculated result is 0.3284301153.
