Hardwood flooring is a beautiful and durable investment for your home. But before you start your project, you need to know how much flooring to buy. Purchasing the correct amount is crucial; too little and you'll face delays and extra costs, too much and you'll waste money. This guide will help you determine the exact amount of hardwood flooring to purchase.

Calculating Your Hardwood Flooring Needs

The first step is accurately calculating your square footage. This involves measuring the length and width of each room, then multiplying to find the area. Don't forget to account for all areas to be floored, including hallways and closets.

Measuring Your Space

Measure the length and width of each room in feet. Use a measuring tape for accurate readings. Note any irregularities in the room shape; you might need to break it down into smaller, easier-to-measure sections.
Calculate the area of each room. Multiply the length by the width of each room to get the square footage. For example: a 10ft x 12ft room is 120 square feet (10 x 12 = 120).
Add up the total square footage. Once you have calculated the area of all rooms you intend to floor, add them together to get the total area.

Accounting for Waste

This is where many DIYers make mistakes. Hardwood flooring installation inevitably results in waste due to cuts, mistakes, and unusable pieces. The amount of waste varies depending on factors like:

Floor plan complexity: Rooms with many corners, obstacles, or odd shapes will produce more waste.
Wood type and size: Larger planks generally result in less waste than smaller ones.
Installation method: Certain installation methods (e.g., using intricate patterns) may lead to higher waste.

How much extra should you buy? A general rule of thumb is to add 10% to your total square footage for standard rectangular rooms and straightforward installations. For more complex layouts or intricate patterns, add 15-20%, even more for highly irregular spaces.

Example: If you need 500 square feet of flooring, add 50 square feet (10% of 500) for a total of 550 square feet. For a complex layout, add 75-100 square feet (15-20%).

Specific Scenarios and Considerations

What if I'm using multiple types of wood?

If you're using multiple types of wood in different rooms, calculate each area separately. Follow the same waste calculation process for each type.

Irregular Spaces and Obstacles

Dealing with unusual spaces like arches, columns, or built-in features requires careful planning and potentially more waste. Consider carefully how you will cut the boards around these areas. Adding up to 20% extra is recommended here.

What about damaged or flawed boards?

Always account for the possibility of damaged or flawed boards. Reputable suppliers usually have a damage allowance, but it's better to be safe than sorry and add a few extra square feet.

Beyond Square Footage: Other Important Factors

Box Quantity: Hardwood flooring is often sold in boxes, each covering a specific square footage. Check the square footage per box to determine the number of boxes you'll need. Always round up to the nearest whole box.
Supplier Recommendations: Your flooring supplier is a valuable resource. Consult with them about your project, including the complexity of your floor plan and the type of wood you've chosen. They can provide tailored advice on how much extra to order.
Future Needs: Consider any future expansions or renovations. Buying a little extra can save you money and hassle down the line.

Conclusion: Avoiding Costly Mistakes

Buying the right amount of hardwood flooring is essential for a successful project. By carefully measuring your space, accounting for waste, and considering additional factors, you can avoid costly delays and ensure you have enough flooring to complete your project without excessive leftover materials. Remember to always consult with your supplier for expert advice, tailoring your extra purchase to your specific situation. Your beautiful new hardwood floors will be worth the careful planning!
