The Crown Molding Miter Angle and Bevel Angle calculator will print out the Miter Angle and Saw Blade Bevel Angles for corner angles 0-360 and spring angles 0-90.

Spring Angle
Degrees input: use any crown spring angle in degrees like 38.00°

Wall Angle
This is the corner angle of the building. Most crown corners are at 90°. For Octagons and 45° BayWindows use an Wall Angle of 135°. For Hexagons use an Wall Angle of 120°.

Calculate Spring Angle.
Use the Spring Angle Calculator to enter the rise and run of the crown molding to calculate the spring angle for the crown molding your using.
