Crown Molding Calculator

Getting perfect crown molding joints shouldn't require guesswork or complicated math. Crown Molding Calculator gives you precise miter and bevel angles instantly — right on your job site.

Whether you're a professional trim carpenter, contractor, or a dedicated DIYer tackling your first crown molding project, this app eliminates the frustration of figuring out compound miter saw settings. Enter your wall corner angle and spring angle, and get exact cut settings in seconds.

WHAT YOU GET:

• Instant miter and bevel angle calculations for any wall corner (60°–145°) or roof pitch (1°–45°) • 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 • Complete reference table covering the entire angle range at a glance • Real-time updates as you adjust values with sliders or direct input • PDF export — save and share your saw settings, take them to the job • Clean, intuitive interface designed for quick use on site

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.
