Flooring quantity
Printed on the carton — it varies a lot by product.
Extra material for cuts, spillage and breakage.
Boxes needed

boxes
- Floor area
- 180ft²
- Area including waste
- 198.0ft²
- Underlay
- 180ft²
How this is calculated
boxes = (area + waste) ÷ coverage per box, rounded up
- Coverage per box is an input because it varies from about 15 to 30 ft² between products — always read the carton.
- 10% waste covers a straight layout; use 15% for diagonal installs and long narrow rooms.
- Underlay is quoted at the bare floor area — it is not cut to a pattern, so it needs no waste factor.
- Buy the whole job in one batch: dye lots differ between production runs.
Questions Fréquentes
How does the Flooring Calculator work?
It applies the formula boxes = (area + waste) ÷ coverage per box, rounded up. Enter your measurements and the result updates instantly in your browser — nothing is uploaded and no sign-up is needed.
Why should I include a waste allowance?
Offcuts, spillage, breakage and an uneven sub-base all consume material that the raw geometry does not account for. The default allowance is deliberately modest; increase it for complex layouts, and remember that running short usually costs more in a second delivery than the surplus did.
Are the results exact?
They are a close estimate, not a guarantee. Coverage per box is an input because it varies from about 15 to 30 ft² between products — always read the carton. Real materials vary by supplier, moisture content and compaction, so confirm the rate with your supplier before placing a large order.
Is this tool free?
Yes, completely free with no registration. All calculations happen client-side in your browser.
Does it work on mobile?
Yes. The calculator is fully responsive and works on phones and tablets in any modern browser — useful when you are measuring on site.

How the calculation works
boxes = (area + waste) ÷ coverage per box, rounded up
The result depends on a few standard constants, which are stated on the page rather than hidden:
- Coverage per box is an input because it varies from about 15 to 30 ft² between products — always read the carton.
- 10% waste covers a straight layout; use 15% for diagonal installs and long narrow rooms.
- Underlay is quoted at the bare floor area — it is not cut to a pattern, so it needs no waste factor.
- Buy the whole job in one batch: dye lots differ between production runs.
Getting an accurate estimate
Measure twice. Small errors in a linear dimension compound, because material volume scales with two or three of them at once — a 6-inch error across a 20-foot run is over a cubic foot of material on a 4-inch pour.
Keep the waste allowance. The default is deliberately conservative: offcuts, spillage, uneven sub-base and breakage are all real, and running short mid-job usually costs more in a second delivery than the surplus did.
Round up when you order. Suppliers sell in fixed increments — quarter yards, whole bags, full boxes — so treat the figure here as the minimum you need rather than the exact amount to buy.
