A hallway with 30 feet of total wall trim area and no door breaks needs about 2 sticks of 16-foot baseboard.
How to use this tool
- Measure each wall and add the lengths for the room perimeter.
- Total the width of doorways and openings that get no baseboard, and enter it.
- Set a waste factor (10% for a simple room, more for many corners).
- Enter the length of the trim boards you'll buy.
- Read the linear feet needed and the number of sticks to purchase.
Find the trim sticks needed for a straight hallway or corridor with no door openings to subtract.
Frequently asked questions
- How much baseboard do I need?
- Add up the room perimeter, subtract the width of doorways, then add about 10% for waste. Divide by your board length and round up. A room with a 40 ft perimeter and 6 ft of doors needs roughly 37 ft, or three 16 ft sticks.
- How much waste should I add for trim?
- About 10% for a simple rectangular room. Rooms with many corners, bays, or short walls generate more off-cuts, so use 15% or more.
- What length of trim boards should I buy?
- Longer boards (12-16 ft) reduce visible joints on long walls but are harder to handle and transport. Match the stick length to your longest walls when possible.
