Most flooring is priced by the square foot but is sold by the box.
The square footage is the actual measurement of the area to be covered by flooring. A waste factor of 5% must be added to the amount of square footage of flooring needed to allow for cutting waste.
Example: 10′ x 15′ room
10’x 15’ = 150 sq. ft.
5% x 150 sq. ft. = 7.5 sq. ft. = 8 sq ft
Total sq. ft needed = 158 sq. ft.
Sq. ft. per box = 18 sq. ft.
158/18 = 8.8 = 9 boxes
Number of boxes purchased = 9 boxes
The cutting waste also allows for some minor defects if any in the wood to be cut out.
