Baseboard Calculator
Estimate baseboard linear feet and sticks to buy.
Baseboard is sold by the linear foot. Measure the room perimeter, subtract door openings, and add 10% for miter cuts and scarf joints. A 12 × 14 ft room has a 52 ft perimeter; after subtracting openings, about 46 ft of trim, plus waste, means five 10-ft sticks. Enter your room dimensions to estimate linear feet, sticks, and inside and outside corner counts.

How does the baseboard calculator work?
Baseboard covers the room perimeter minus door openings (~3 ft each). Add 10% for cut waste and divide by stick length.
What else do people ask about this calculator?
How is baseboard sold?
Typically in 8, 12, or 16 ft sticks. Longer sticks reduce joints on long walls but ship poorly.
Do I subtract windows?
No — baseboard runs under windows. Only subtract doorways and openings that reach the floor.
