Flooring Material Calculator
Estimate how many flooring units you’ll need. Enter your total floor area, select a flooring type (or enter a custom coverage), and set a waste allowance.
How It Works
We first calculate your effective area by adding waste:
effective area = area × (1 + waste / 100).
Then we divide by your chosen coverage per unit and round up:
units needed = ceil(effective area / coverage).
This gives the number of boxes or rolls you must order to cover your project.
Choosing Your Floor
Laminate is budget-friendly and easy to fit; engineered wood offers stability; solid wood grants authenticity. Compare in our Best Flooring Reviews 2025.
Preparing Subfloors
Ensure your subfloor is clean, level and dry to avoid squeaks or warping. Follow our Subfloor Preparation Guide.
Waste Tips
10% waste covers small cuts—if your room has many angles or a complex layout, consider 15% waste.

Frequently Asked Questions
How do I measure the area?
Measure each room’s length × width, subtract permanent fixtures, then sum all areas.
Why include waste allowance?
Waste accounts for cuts and mistakes—typically 5–10%, more for complex layouts.
Can I use for carpet or vinyl?
Yes—select the appropriate unit or use “Custom” to enter your own coverage per roll or box.
What coverage values should I use?
Use the manufacturer’s m²-per-box or m²-per-roll. If unknown, choose “Custom” and enter the value.
