Baseboard runs around the room except at doorways. The calculator takes the perimeter, subtracts the door openings, adds waste for the miter cuts and counts the pieces.
If you're cutting tile baseboard from your floor tiles, it also tells you how many strips you get per tile and how many tiles that takes.
How to use
- Enter the room size, several rooms, or type the perimeter.
- Set the number of doorways and their width.
- Choose the piece length sold in your store.
- For tile baseboard, tick "Cut from floor tiles" and enter the tile size and baseboard height.
Waste for corners
Each inside and outside corner needs a miter or coped cut, and short leftovers rarely fit anywhere else. 10% extra covers a normal room; add more for rooms with many short walls.
Tile baseboard
A 24 in tile cut into 3 in strips gives 7 strips 24 in long. The calculator leaves about 1/8 in for each saw cut.
