Calculate miter saw protractor angles
Miter saw angles - typical in corners and similar - can be hard to measure.
By measuring the three lengths a, b and c as indicated in the drawing below - the miter saw cutting angle can easily be calculated with the angle calculator:
length a (mm, in)
length b (mm, in)
length c (mm, in)
Angle A (degrees):
Angle B (degrees):
Angle C (degrees):
Miter Saw Angle (degrees):
Tip! - Distance c can be difficult to measure in corners. It may be helpful to use a stick or something similar with a known length for c. Position the stick somewhere in the corner as indicated in the drawings below. Measure the lengths a and b from the bottom of the corner to the ends of the stick.
Examples - Miter Saw Angle Calculator
The first example below with the default values used in the calculator above calculates the miter saw angle to 26.4 degrees for length a = 33.5, b = 40 and c = 39.1.
The second example calculates the miter saw angle to -26.5 degrees (miter saw opposite side compared to the first example) for lengths a = 33.5, b = 4 and c = 62.6.
