Crown runs the whole perimeter with no gaps for doors, and every corner eats material.
How it works
Perimeter × 1.15, divided by stick length, rounded up.
Before you order
- Cut crown upside down and backward on the saw, or use a jig.
- Cope inside corners; miter outside ones.
- Find ceiling joists with a stud finder before you nail through the top edge.
Common questions
How much extra crown should I buy?
About 15%, since cuts at corners waste more than with baseboard, and the first few are practice.
Does crown size change the amount?
Not the length you buy. A larger profile just takes a bigger cut and more wall above the door head.
