The calculation

  1. 120 × (1 + 10/100) = 132
  2. ceil(132 ÷ 20) = 7

Before ordering, use the flooring cartons, layout & waste planning guide to check the inputs and take the right questions to the supplier. Choose another calculator.

How to plan the quantity

Measure each room at its widest dimensions, then split an L-shape into non-overlapping rectangles. Subtract only areas that will actually stay uncovered.

Rooms using the same flooring share one combined allowance and box round-up. Different products, colors or batch requirements need separate lists.

Measure doorways and changes of flooring for transitions. Their length does not come from room area, and baseboards may need separate work.

Before you order

  • This does not lay out plank stagger, carpet seams or sheet-roll cuts. Confirm the layout before ordering a patterned or roll product.
  • Subfloor leveling, moisture control, underlayment, stairs and trim are outside the box count.
