Crown cuts depend on spring angle and saw setup

This calculator estimates material and a simple square-corner miter note. Compound miter and bevel settings vary by spring angle, corner angle, saw orientation, cope strategy, and product profile. Test cuts before installing.

Crown molding formula

Room perimeter = 2 × (length + width) × rooms

Net crown = perimeter - opening deductions

Order length = net crown × (1 + waste %)

Sticks = order length ÷ stock stick length

Sample takeoff

A 12 ft by 14 ft room with no deductions, 12 ft sticks, and 15% waste needs about five sticks and 59.8 linear ft of crown.A 3.6 m by 4.2 m room with no deductions, 3.6 m sticks, and 15% waste needs about five sticks and 17.9 m of crown.

Crown Molding Calculator FAQ

How does this crown molding calculator work?+

It multiplies measured job dimensions by the coverage, spacing, or package yield you enter, adds waste, then rounds the buy quantity up. For cut settings, use the crown profile spring angle, corner angle, and saw method recommended by the product or installer.It multiplies measured job dimensions by the coverage, spacing, or package yield you enter, adds waste, then rounds the buy quantity up.
