How Much Flooring Do I Need for a 10x12 Room?

Quick Answer

A 10x12 room is 120 square feet. With 10% waste, buy about 132 square feet of flooring, then divide by square feet per box.

Use the [Flooring Calculator](/flooring-calculator) to adjust the dimensions, waste factor, product coverage, and unit price for your exact project.

Formula

``

Boxes needed = length x width x waste factor / box coverage

``

Example Estimate

1. Area is 10 x 12 = 120 square feet.

2. Add 10% waste: 132 square feet.

3. If a box covers 23 square feet, 132 / 23 = 5.74.

4. Round up to 6 boxes.

Reference Table

| Material | Suggested waste |

|---|---:|

| Vinyl plank | 5% to 10% |

| Laminate | 8% to 10% |

| Hardwood | 10% to 15% |

| Carpet | 10% to 20% |

Practical Tips

- Check box coverage before buying.

- Keep one unopened box if the return policy allows.

- Acclimate flooring as the manufacturer recommends.

When to Round Up

Round up when the project has cuts, corners, fragile materials, uneven surfaces, delivery minimums, or any chance that matching the same product later will be difficult.
