I have heard this question many times.  How do I cut crown molding?

Quick note for everyone. Buy more crown molding than you think you will need.  The extra 10′ of molding will be a lot less money than the time and money you will spend on gas.

I still remember the time I asked a worker to put crown molding up in a room only to come back 2 hours later with 1 single piece of molding up in the room.  I asked what was taking so long.  He told me it took him over an hour to adjust the 2 angles on the saw.  Unfortunately, I assumed he know the “simple crown molding trick“.  Crown molding can be incredibly tricky unless you know the trick.

The simple trick to cut crown molding:

  1. Angle your mitre saw at 45 degrees
  2. Place your crown molding on the saw upside down at the angle that it would be placed against the wall/ceiling
  3. Make your cut
  4. Place and adjust
The key is STEP 2.  Place your crown molding upside down on the saw at the angle that it would be placed against the wall/ceiling
