Multiply room length × width in feet for square footage. Add 10% waste for standard straight installation; add 15% for diagonal patterns. Divide by the coverage per bundle shown on the product label and round up to the nearest full bundle.
Strip hardwood (2-1/4 in wide) typically packages 18–22 sq ft per bundle. Wider plank products (3–5 in) may package 20–25 sq ft per bundle. The exact coverage is always printed on the bundle label — use that number.
Use 10% for straight installation running parallel to the longest wall. Use 15% for diagonal (45°) installation. Add an extra 5% (total 15–20%) for very small rooms where proportionally more perimeter cuts are required.
Most hardwood manufacturers recommend acclimating flooring in the installation space for 3–5 days at normal living conditions (60–80°F, 30–50% relative humidity). Check the specific product's installation guide for the manufacturer's acclimation requirement.
Some engineered hardwood products are approved for radiant heat; most solid hardwood is not due to expansion concerns. Check the manufacturer's installation guide — it will specify if radiant heat is compatible and any maximum temperature limits for the subfloor.
