Miter saw settings for polygons, arbitrary corners, and segmented work.
Each piece gets the miter saw angle on both ends. Two pieces join to form the interior corner.
Common settings:
A six-sided frame needs 30° miters, an eight-segment bowl ring 22.5° — and a "square" room corner is rarely 90°. Enter the segment count or the measured corner angle and get the exact miter (and bevel, for compound cuts) to set on the saw.
Save your numbers, not just crunch them
Members save cut lists and estimates to projects, feed them into the cost estimator, and track real spend against the plan.
Each miter is 360° ÷ (2 × 6) = 30°. In general, divide 360 by twice the number of sides.
Measure the actual corner with a protractor or bevel gauge and cut each piece at half that angle — two 44° miters close a 88° corner cleanly.
