The following calculator is to be used to determining the table and blade angle in degrees and are based on the use of a power miter saw. All mouldings should be cut face up. Alternatively, you can click here for a table of common angles.
The table and blade angles represented on this website are meant as a guide and/or starting point only. Minor adjustments are required.
The wall angle of any crown moulding can be easily calculated by taking a cut-off of your moulding and place inside a framing square as illustrated in the diagram below. Take the ceiling and wall measurements and enter them into the calculator below.
The formula used below is as follows:
Wall Angle = atan(Ceiling / Wall) * 180 / 3.1415
