Flooring Calculator
Calculates floor area, adds a waste factor appropriate to your install pattern and converts it into whole boxes plus an estimated material cost.
- Floor area
- 192 sq ft
- Material cost
- $648
- Spare coverage
- 20 sq ft
- · Order all boxes in one run so the batch and shade match.
- · Keep one spare box sealed — repairs years later are near-impossible to colour match.

Frequently asked questions
Does the result include waste?
Yes. It applies the waste percentage you enter before rounding up to complete boxes.
How do I measure an irregular room?
Split it into rectangles, calculate each area, add them together, then enter equivalent overall dimensions or use the total when ordering.
Should I keep spare flooring?
Yes. Keep at least one sealed box for repairs because matching the same finish years later can be difficult.
