Crown molding different ceiling heights.
According to houzz this tip can come in handy for ceilings 10 feet tall or higher consider a rule of thumb allowing 1 of width for each foot of ceiling height.
There are of course more variations but these three examples cover the basic design aspects that you need to consider during the planning stages.
These larger crowns are often built up using 2 or more moulding profiles and are also referred to as a cornice.
For 9 foot ceilings 3 to 7 inches and for 10 foot ceilings 3 to 8 inches.
The continuous header idea is an additional bridge the same height as the moulding on the 42 unit which is attached to the ceiling with the same continuous crown on it spanning across the lower 30 unit.
This scenario includes both ways to end a lower level crown on adjacent cabinets.
Ceilings that are 9 feet tall can sustain a larger crown typically 3 7 1 2 plus the addition of a picture mold in formal public spaces.
The crown moulding does not have to be at a 45 degree angle.
Some suggested crown mouldings for 9 foot ceilings.
The height of the room as you can probably imagine the height of the ceilings in a room really play a role in whether or not crown molding is good choice.
Adjust upward for larger rooms.
You can alter the angle to get a lesser projection with good looking results.
Nine to 10 feet estimate crown molding width by permitting 1 2 inch of rise for each foot of ceiling height in a room with ceilings measuring 9 to 10 feet.
