Miter Angle Calculator
Calculate miter angles for polygonal frames and projects
About this calculator
The Miter Angle Calculator determines the precise cutting angles needed for joining pieces in polygonal frames and woodworking projects. Whether you're building picture frames, window trim, or decorative panels, this tool calculates the exact miter angles required for perfect joints. By inputting the number of sides in your polygon, the calculator provides the accurate angles needed for each cut, ensuring seamless connections and professional-looking results in your carpentry and crafting projects.
How to use
Enter the number of sides for your desired polygon shape into the calculator. The tool will automatically compute the miter angle needed for each cut. Use this angle setting on your miter saw or cutting tool to create precise joints that fit together perfectly when assembled.
Frequently asked questions
What is a miter angle in woodworking?
A miter angle is the cutting angle needed to join two pieces of material at a corner, typically half of the interior angle of the desired corner joint.
How do I calculate miter angles for odd-sided polygons?
The miter angle equals 90° minus (180° ÷ number of sides). For example, a pentagon requires 54° miter cuts for each joint.
Can this calculator work for any polygon shape?
Yes, the calculator works for any regular polygon from triangles to complex multi-sided shapes, providing accurate miter angles for perfect joints.
