Crown moulding is a stylish addition to any home. When installing crown moulding, you will have to cut the lengths of moulding at an angle to fit around corners. Whether you cut crown moulding at a 45-degree or 22.5-degree angle, the process is essentially the same. A mitre saw makes cutting crown moulding a lot easier. A mitre box can also be used to cut the crown moulding.

Skill level:

Things you need

  • Measuring tape
  • Crown moulding
  • Pencil
  • Mitre saw

  1. 1

    Measure the width of the wall where the crown moulding will be installed with a measuring tape. Use the measuring tape and a pencil to mark the same measurement on the length of crown moulding.

  2. 2

    Lay the crown moulding face down on the mitre saw. The bottom of the moulding should touch the fence of the mitre saw and the top of the moulding should rest on the mitre saw table. Hold the moulding in this position whenever you make a cut to the crown moulding.

  3. 3

    Set the mitre saw to a 45-degree angle. Hold the crown moulding firmly in place and cut the 45-degree mitre.

  4. 4

    Follow the same process, but with the mitre saw set to a 22.5 degree angle, to make a 22.5-degree mitre cut.

Tips and warnings

  • As a low-tech alternative to the mitre saw, you can use a mitre box and hand saw to accomplish the same cut.
