The Crown Moulding Calculator.

Use the calculator below to determine the correct Miter and Bevel angle to set your CMS or SCMS to cut any angle crown moulding at any wall angle by laying it flat on the saw table. For a complete overview of how to cut and install Crown Moulding Click Here.

If you need help determining your wall and crown moulding angles click on the links below.

If you want the equations for use with any Scientific Calculator they are:

miter = tan^-1(( sin(crown angle) / tan( wall angle / 2 ))) for any angle of crown or wall.
bevel = sin^-1(cos(crown angle) * cos( wall angle / 2)) for any angle of crown or wall.
