Add a second room and closets for a single order, whichever material you are laying.

How it works

Each room area plus closets, raised by your extra percentage, then divided by carton coverage.

Before you order

  • Buy all cartons from the same lot so color runs true.
  • Run boards toward the main light source or the longest view.
  • Keep a spare carton for repairs.

Common questions

How much extra flooring should I buy?

About 10% for straight layouts, and 15% or more for diagonal or rooms with many cuts.

Do I include closets?

Yes, and the floor usually continues through them, so add them here.
