For 9 foot ceilings 3 to 7 inches and for 10 foot ceilings 3 to 8 inches.
Crown molding different ceiling heights.
I m going to show three examples of ways to deal with crown moulding at different heights.
Webber this crown is paired with crisply milled dentil molding and beaded baseboard.

Adjust upward for larger rooms.
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 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.
There are of course more variations but these three examples cover the basic design aspects that you need to consider during the planning stages.
You can alter the angle to get a lesser projection with good looking results.
The crown moulding does not have to be at a 45 degree angle.
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.
Some suggested crown mouldings for 9 foot ceilings.
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.
