Calculator
Baseboard length calculator
Length plus width, twice, minus the doorways. Add your rooms and see how far you walk.
| Room | Length, ft | Width, ft | Doorways | Baseboard, ft |
|---|---|---|---|---|
Total baseboard ft
A doorway is counted as 3 feet. Cabinets and built-ins that cover the wall shorten the run further.

What the total means
Four rooms with nine doorways add up to 169 feet of baseboard. Dusting it by hand means kneeling for every one of those feet. With Baseboard Buddy you walk them.
