How to find your box coverage

The coverage is printed on the box. Look for:

“Coverage: X sq ft per carton”
“X sq ft per box”
Or calculate: (board length × board width × boards per box) ÷ 144

Use the Flooring Calculator and enter your product’s exact box coverage for a precise count.

How do I find the box coverage for my flooring?

The box coverage (or "carton coverage") is printed on the box label, usually in the format "covers X sq ft per carton" or "X sq ft per box." It varies by product, brand, and board width.

How many extra boxes of flooring should I buy?

Always buy at least 10% extra for waste cuts. Additionally, keep 1 unopened box for future repairs — flooring dye lots change between production runs, making it difficult to match later.

Can I use leftover flooring in another room?

Yes, if the rooms use the same product. This is another reason to overbuy slightly — extra flooring from a first room can be used in a closet or small area later.
