Miter Angle Calculator
Polygon Miter Angle
Calculate miter angle for regular polygons
Formula
Miter Angle = 180 / N | Interior Angle = (N-2) x 180 / N | where N = number of sides
Frequently Asked Questions
What angle do I set my miter saw to?
For a regular polygon, divide 180 by the number of sides. For a 4-sided frame, 180/4 = 45 degrees. For a hexagon, 180/6 = 30 degrees.
How do I cut a perfect picture frame?
A picture frame is a 4-sided polygon, so set your miter saw to 45 degrees. Ensure your material is flat and consistently sized for best results.
