6 boxes
120 square feet of floor · 20 sq ft per box
A 10 by 12 ft room is 120 square feet of floor, which takes 6 boxes of laminate flooring at 20 square feet per box. Use the square feet printed on your box, and add a waste allowance for cuts.
A worked example
A 14 by 11 1/2 ft bedroom, from boxes of 23.4 sq ft with a 7% waste allowance, needs 8 boxes. 161 square feet of floor plus 7% is 172.3 square feet. At 23.4 square feet a box that is 7.36 boxes, and a part box still has to be bought, so 8.
How do I measure a room for laminate flooring?
Measure the length and width of the floor in feet, wall to wall, and multiply. For an L-shaped room or a room with a closet, split it into rectangles and add them: a 12 by 10 ft room with a 3 by 5 ft closet is 120 plus 15, 135 square feet. Enter the total as the length with a width of 1, or enter each rectangle in turn and add the boxes.
What else it is called
Laminate flooring is sold by the box, also called a carton or case, and every box prints the square feet it covers. Floating vinyl plank and engineered wood are sold the same way, so the same count works for them with the coverage from their box.

Square feet to buy. Divide by the square feet printed on your box and round up to whole boxes.
Where the numbers come from
- Boxes are the floor area plus your waste allowance, divided by the square feet per box, rounded up to whole boxes.
- Coverage per box is the figure printed on the box you are buying. It changes with the brand and the plank size, so the page takes yours instead of assuming one.
Measure the floor wall to wall, including closets and the space under appliances you will floor under. The count is for the planks only: underlayment, transition strips and baseboard or quarter round are sold by their own coverage and length.
