How it's calculated

  • Flooring and underlayment = floor area, + waste.
  • Boxes = flooring ÷ coverage of one box, rounded up.
  • Baseboards = room perimeter, + waste. Pieces = baseboards ÷ length of one piece, rounded up.

Measure once. The rest follows.

In KOR, this calculation happens on its own from your plans: trace each room on the plan, and the area, waste and prices follow into the estimate.
