The Skirting Saw Angle can be useful when cutting decorative mouldings, skirting boards and similar where the angle between the pieces are not 90 degrees and the cross cuts are not 45 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.
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.
