How to Calculate How Much Hardwood Flooring I Need

Calculating the amount of hardwood flooring needed for a project ensures you have enough material to complete the installation without running short. By following these steps, you can determine the necessary square footage of flooring accurately.

1. Measure the Room

Measure the length and width of the room in feet. For irregular-shaped rooms, divide it into smaller rectangles or triangles and calculate the area of each section separately.

2. Calculate the Area

Multiply the length by the width of the room to determine the area in square feet. For example, a room that is 12 feet long and 10 feet wide would have an area of 12 x 10 = 120 square feet.

3. Add Waste Allowance

Account for cutting and waste by adding 10-15% to the calculated area. This ensures you have enough material to cover irregular cuts and potential mistakes.

4. Determine Plank Coverage

Check the manufacturer's specifications to find the square footage covered by each plank. For example, a plank that is 5 inches wide and 36 inches long would cover 5/12 x 36/12 = 1.5 square feet.

5. Divide Total Area by Plank Coverage

Divide the total area, including the waste allowance, by the plank coverage to calculate the number of planks needed. Round up to the nearest whole number to ensure you have sufficient material.

Additional Considerations

Consider the direction of the planks. Diagonal or herringbone patterns require more material than straight installations.
Measure the installed area before purchasing to ensure accuracy.
Purchase extra planks for repairs or future replacements. A minimum of 10% is recommended.
Consult with a flooring professional for more precise calculations and professional advice.
