Estimate linear length, pieces, waste and cost.
Enter the room perimeter, door openings and stock length to estimate pieces, purchased length and optional cost.
Includes your selected waste allowance.
Baseboard normally stops at door openings, but trim details vary. Adjust the average door width or set door count to zero if you prefer to purchase from the full perimeter.

Convert a room perimeter into the number of full baseboard or skirting lengths you should buy, including door deductions and waste.
PlanCalq starts with the room perimeter, subtracts the selected doorway width, and adds the waste allowance for mitres, joins and offcuts.
That recommended linear length is divided by the stock length and rounded up to a whole piece.
2 × (room length + room width) = perimeterPerimeter − doorway deductions = net trim lengthNet length × (1 + waste %) ÷ stock length = pieces to buy (rounded up)Normally no, so the calculator can deduct door widths from the room perimeter.
More corners, mitres, damaged ends and short offcuts usually increase waste. Adjust the percentage to match the room complexity.
The same perimeter logic can provide a rough quantity, but ceiling details, corners and profiles may require a different waste allowance.
