• Support for all standard spring angles (38°, 45°, 52°) and custom values
• Interactive visual diagrams: corner angle, miter gauge, bevel gauge, and spring angle cross-section

TWO CUTTING METHODS EXPLAINED:

1. Non-Compound (Vertically Nested) — molding positioned in the saw as it sits on the wall
2. Compound (Flat Down) — molding flat on the saw table with calculated miter and bevel angles

WHY PROFESSIONALS TRUST THIS APP:

Crown molding is one of the trickiest finish carpentry tasks. Walls are rarely perfectly square, and standard 45° cuts only work on perfect 90° corners. This calculator handles real-world angles — saving you time, material, and frustration on every job.
