# Miter Saw Angle Calculator

## Calculate miter saw protractor angles

A miter saw cutting angle can be calculated by measuring the length a, b and c as indicated below.

*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 length a and b from the end of the stick to the bottom of the corner.

### Examples - Miter Saw Angle Calculator

The first example below with 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.
