Enter your room sizes and get your square footage, how many boxes to buy, the right waste amount, and an estimated total material and installation cost — in seconds.
Follow these steps so you buy the right amount and avoid the mistakes that cost DIYers money. Tap "Learn" if a term is new.
For general guidance only. Always follow the flooring manufacturer's instructions and check your product's box label for exact coverage.
Flooring is sold by the box, not the square foot, and boxes can't be split. Rounding up guarantees you have enough material to finish the room — buying short means a second trip and the risk the store is out of your exact dye lot.
It covers cuts, trimming around edges, doorways, and closets, and pieces ruined during install. A straight-lay install typically needs about 5–10% extra; diagonal or herringbone patterns need more — often 15% or higher — because more cuts are wasted.
For an L-shaped or irregular room, measure it as two or more separate rectangles and add the totals together before entering the number here. Entering one rough estimate for an odd-shaped room is the most common way people under-order material.
This calculates the flooring material and box count only. Underlayment, transition strips, adhesive, and trim are separate purchases — check your specific product's install instructions for what else it requires.
Coverage per box depends on the plank size and how many planks are packed in, which differs by manufacturer and product line. Always check the actual "sq ft per box" printed on your specific product's packaging rather than assuming it matches another brand.
