How it is worked out
Floor area is length times width for each room. The calculator adds your waste allowance for cuts and divides by the coverage printed on one box. Trim is the room perimeters less 0.8 m for each doorway, plus 10% for joins.
How our flooring takeoff service works →Common questions
How much extra flooring should I buy?
Add 5% for large, square rooms, 10% for most houses and 15% for diagonal or herringbone layouts. Buy all the boxes from one batch so the colour matches.
Can you measure flooring from my plans?
Yes. Send the PDF plans and Sigma Build measures every room by floor finish from the drawings and prices the job at your rates.
