About this calculator

Use the Baseboard Length Calculator to get 2 linked results (Plus 10% waste, 2.4 m lengths) from a single number. It is built for home & construction jobs where a quick, repeatable answer beats guesswork. Skirting runs around doors and openings, so subtract door widths from the perimeter.

How it works

The calculator multiplies your input by a fixed coefficient for each line. For example, every 1 m gives 1.1 m for plus 10% waste.

Worked example

If you enter 30 (Room perimeter (m)), Plus 10% waste comes to 33 m and 2.4 m lengths comes to 13.75 pieces.

Common mistakes

• Skirting runs around doors and openings, so subtract door widths from the perimeter.
• Skipping the check against local building code or manufacturer data.
