Miter angle chart
Saw settings for shapes with 3 to 12 equal sides.
Set your miter saw to the angle in the third column, measured from a square cut, and cut the same angle on both ends of every piece. The corner angle is the angle where two pieces meet. For other numbers of sides, use the miter angle calculator.
