Trim count is an order estimate

Inside corners, outside corners, scarf joints, stain-grade matching, returns, stairs, cabinets, and damaged cuts can change the final stick count.

Quarter round formula

Perimeter = 2 × (room length + room width) × rooms

Measured trim = perimeter - opening deductions

Order length = measured trim × (1 + waste %)

Sticks to buy = order length ÷ stock length

Sample takeoff

One 12 × 14 ft room with 6 ft of doorway deductions needs about 51.5 linear ft after 12% waste. With 12 ft sticks, buy 5 sticks.One 3.6 × 4.2 m room with 1.8 m of doorway deductions needs about 15.5 m after 12% waste. With 3.6 m sticks, buy 5 sticks.
