What angle is a Mitre joint cut at?

A mitre joint (miter in American English, sometimes shortened to mitre) is a joint made by beveling each of two parts to be joined, usually at a 45° angle, to form a corner, usually a 90° angle. For woodworking, a disadvantage of a mitre joint is its weakness, but it can be strengthened with a spline.

How do I make my miter joints tighter?

To assure tight fitting corners, set your saw (or miter box) to the desired angle and cut a pair of sample pieces. Put the pieces together and check it with the largest, most accurate square or angle gauge you have. If your cuts are off by only a degree or two, the resulting corner will show a visible gap.
