How does the flooring calculator work?
Multiply room length × width to get square footage, add a 10% waste allowance, and divide by the box coverage printed on the manufacturer label.
What else do people ask about this calculator?
How many boxes of flooring for 1,500 sq ft?
About 75 boxes at 22 sq ft per box, including a 10% waste allowance. Diagonal or herringbone layouts add 5% more waste.
Should I always order extra flooring?
Yes — keep 3–5 leftover boards for repairs. Manufacturers change dye lots frequently, so a matching replacement in two years may be impossible.
How much waste for hardwood flooring?
10% is standard for straight installs; add 5% more for diagonal, complex patterns, or rooms with many angles.
How many square feet in a box of laminate?
Typically 20–30 ft² per box. Check the box — it's the most reliable number for your specific product.
