How to Estimate Baseboard
The calculator finds the perimeter of each rectangular room, subtracts the total width of openings that will not receive baseboard, and adds waste for cuts and joints.
Formula
Baseboard length = Room perimeter − Openings + Waste
Stock pieces are rounded up to the next whole piece. Confirm available lengths and plan joints before buying.
