How to Use This Calculator

Measure wall corner angle with protractor (usually 90°). Check crown molding packaging for spring angle (38° or 45°). Calculator provides compound miter saw settings.

Why Accurate Crown Molding Angle Matters

Crown molding requires compound cuts (miter + bevel). Spring angle affects the bevel needed. Non-90° corners need angle adjustments. Proper calculations eliminate gaps and ensure tight joints.

Common Mistakes to Avoid

Not checking crown spring angle, measuring incorrectly (inside vs outside corner), forgetting left vs right cuts, and not testing on scrap first.
