Calculate floor area and the number of flooring cartons needed, including a configurable allowance for cuts and defects.
Rectangular rooms using laminate, vinyl plank, engineered wood, or other boxed flooring products.
An 18 ft × 14 ft room with cartons covering 22.5 ft² shows how room area becomes a carton count.
Default example result: 277.2 ft² with 10% allowance.
The calculator uses the displayed formula, applies your waste allowance, and rounds purchase quantities up. Review the assumptions before ordering and confirm product coverage with your supplier.
Formula used: length × width × (1 + waste)
Ten percent is a common starting point for a straightforward room. Increase it for diagonal layouts, irregular rooms, or inexperienced installation.
Carton sizes vary by product, so the box coverage printed on the product is more reliable than a generic carton assumption.
