Note that crown molding is cut with the miter saw upside down using the saw s table as a guide to fit the molding to an angle equal to that needed to fit with the ceiling.
Cathedral ceiling crown molding vaulted ceiling angle calculator.
Estimate crown molding width by permitting slightly more than an inch.
The formula does work but you must adjust the crown angle.
If the angle is 18 degrees then you must tilt the straight wall crown half that amount backward 9 degrees and then tilt the vaulted wall crown forward 9 degrees.
Optionally you can tilt one the full 18 degrees.
With a cathedral style ceiling that angle is much more than 90 degrees.
The best way to do it is to make a small transition piece of crown molding that acts like the crown is being installed on a flat ceiling on one side of the piece but on the other edge it is making a transition as if the crown molding is climbing a stairway making the bend that happens as you transition from the sloped ceiling along the stairs to the flat ceiling below or at a flat landing.
The angle on cathedral ceilings poses a challenge.
Crown molding installation on vaulted ceilings.
Taller or vaulted ceilings require significantly wider crown moldings to make a visual impression even in smaller rooms.
Crown molding tools is an iphone app with functions to calculate complex crown miter and bevel angles that other calculators don t offer.
Cathedral or vaulted ceilings.
Crown molding also allows you to calculate the cutting angles for cathedral or vaulted ceilings.
This is easily figured by measuring the angle of the vault.
When in vaulted ceiling mode the input section of the display will change to look similar to the following.
But don t be put off.
Make sure your scrap piece fits squarely into the miter saw before cutting.
Crown molding is generally installed on a 90 degree angle between the ceiling and the wall.

The ceiling angle is the angle of change in the ceiling along the current wall.
Vaulted ceiling crown molding angles.
This usually requires an angle setting of either 32 or 45 degrees.
