Stop guessing at the saw. Crown Molding Angle Calc turns your spring angle and wall corner into the exact miter and bevel numbers to dial into a compound miter saw — with a diagram that shows how to lay the molding down and cut it right the first time. Type the corner angle and pick a spring angle (38°, 45°, 52° presets or your own), choose an inside or outside corner, and read the settings instantly. ▶ COMPOUND MITER + BEVEL — exact miter and bevel angles for any wall corner and spring angle, so a compound saw is set once and cut clean. ▶ FLAT VS NESTED CUTS — switch between cutting the molding lying flat on the saw table or nested against the fence, whichever matches your setup. ▶ SAW SETUP DIAGRAM — a clear visual of how the molding sits and where the blade goes, so the numbers actually make sense. ▶ FRAMES & N-SIDED BOXES — a plain miter mode for picture frames, boxes and any polygon, from a triangle to a many-sided ring. ▶ INCHES OR CENTIMETERS, OFFLINE — works fully offline on the job site, with your choice of units. Built for finish carpenters, trim installers, remodelers and serious DIYers who want the corner to close tight. All math is standard compound-miter trigonometry computed on your device. Always confirm on a test scrap before cutting your final piece.
