Free printable chart." canonical: https://klmlabs.app/construction-calculator/crown-molding-angles/ updated: 2026-11-07 --- # Crown molding angles chart: miter and bevel settings For a 90° corner, 52/38 crown cut flat needs a 31.6° miter and a 33.9° bevel; 45/45 crown needs a 35.3° miter and a 30° bevel. The chart covers corners from 60° to 150°. Download the printable chart (PDF, US Letter, 1 page, 28 KB): https://klmlabs.app/construction-calculator/charts/crown-molding-angles.pdf. Every number is worked out by Construction Calculator 1.1.1's own formulas. ## Crown molding miter and bevel settings, flat on the saw table | Wall corner | 52/38 crown: miter | 52/38 crown: bevel | 45/45 crown: miter | 45/45 crown: bevel | |---|---:|---:|---:|---:| | 60° | 46.8° | 43° | 50.8° | 37.8° | | 65° | 44° | 41.7° | 48° | 36.6° | | 70° | 41.3° | 40.2° | 45.3° | 35.4° | | 75° | 38.7° | 38.7° | 42.7° | 34.1° | | 80° | 36.3° | 37.1° | 40.1° | 32.8° | | 85° | 33.9° | 35.5° | 37.7° | 31.4° | | 90° | 31.6° | 33.9° | 35.3° | 30° | | 95° | 29.4° | 32.2° | 32.9° | 28.5° | | 100° | 27.3° | 30.4° | 30.7° | 27° | | 105° | 25.3° | 28.7° | 28.5° | 25.5° | | 110° | 23.3° | 26.9° | 26.3° | 23.9° | | 115° | 21.4° | 25° | 24.3° | 22.3° | | 120° | 19.6° | 23.2° | 22.2° | 20.7° | | 125° | 17.8° | 21.3° | 20.2° | 19.1° | | 130° | 16° | 19.5° | 18.2° | 17.4° | | 135° | 14.3° | 17.6° | 16.3° | 15.7° | | 140° | 12.6° | 15.6° | 14.4° | 14° | | 145° | 11° | 13.7° | 12.6° | 12.3° | | 150° | 9.4° | 11.8° | 10.7° | 10.5° | To the nearest 0.1°. Outside corners take the same numbers; only the cut direction changes. ## Why 31.6 degrees for crown molding? 31.6° is the miter setting for 52/38 crown in a 90° corner, cut flat. ## What is 33.9 on a miter saw? 33.9° is the matching bevel setting for 52/38 crown in a 90° corner. ## What do 52/38 and 45/45 mean? The two angles the crown makes with the wall and the ceiling. The chart has columns for each. ## Do outside corners need different settings? No. Same two numbers; only the direction of each cut changes. Your saw's crown guide shows which way. ## What if the corner isn't 90°? Measure it with an angle finder and use its row. For 52/38 crown, a 95° corner takes a 29.4° miter and 32.2° bevel; an 85° corner takes 33.9° and 35.5°; a 135° corner takes 14.3° and 17.6°. ## Work out your own with Construction Calculator - Miter and bevel for any crown, not only 52/38 and 45/45 - Enter the wall corner, or the number of sides of a shape - Flat miters for trim and frames, too Download Construction Calculator on the App Store: https://apps.apple.com/us/app/fraction-feet-inch-calculator/id6816445977 Free to download, with in-app purchases.
