Quick answer
Compound miter angles for crown molding depend on the wall corner angle and the molding's spring angle off the wall.
derived from spring angle using standard crown molding miter/bevel tables
How to use the Crown Molding Miter Calculator
- 1Identify the wall corner angle — 90° for a standard inside or outside corner.
- 2Check the spring angle stamped or measured on your crown profile, usually 38° or 45°.
- 3Set your compound miter saw to the miter and bevel angles shown and always test-cut scrap first.

Frequently asked questions
Why does spring angle matter?
Crown sits at an angle off the wall and ceiling, so the cut angles differ from flat trim.
Can I cut crown flat on the saw table instead?
Yes, using a crown-stop jig and different, saw-specific angles, but the compound method shown works on any miter saw.
