Standard coverage: a laminate / luxury-vinyl-plank box typically covers ~18–24 sq ft (NWFA-style carton yields); a case of ceramic/porcelain tile ~10–15 sq ft. Waste of 10% is standard for straight layouts (NWFA / installer guidance).

Frequently Asked Questions

Standard practice is to add 10% for straight layouts and 15–20% for diagonal, herringbone, or tile patterns with more cuts. We default to 10% and let you adjust.
Divide your total square footage (room area plus waste) by the square footage covered by one box, then round up. A typical laminate or vinyl-plank box covers about 18–24 sq ft; a case of ceramic tile about 10–15 sq ft.
Yes. The area math is the same for every material. Enter the box/case coverage for plank or tile products, or enter tile width and length to count individual tiles. Carpet is usually sold by the square yard or roll — the square-footage result maps directly.
