How this flooring calculator works
The calculator uses room dimensions or entered floor area, adds any extra fixed area, applies the waste allowance and rounds up to whole boxes using the coverage per box.
Assumptions
Waste allowance is included because cuts, damaged pieces, pattern matching and irregular rooms can change the amount of material needed. The cost estimate uses the price entered and is not a quote.
What this calculator does not include
This tool does not measure stairs, transitions, underlay, labour, installer requirements or local material prices. It is a general material estimate only.

FAQs
How do I calculate flooring needed?
Enter the room dimensions or known floor area, then add waste allowance and box coverage. The calculator rounds up to whole boxes.
What waste allowance should I enter?
The calculator lets you choose the allowance. Irregular rooms, angled cuts and patterned layouts may need a larger allowance than simple rectangular rooms.
Can I enter square metres?
Yes. Choose metric units to use metres and square metres. Unit changes alter labels and defaults only.
Does this include stairs?
No. This calculator focuses on flat floor areas and simple extra-area allowances.
Why are boxes rounded up?
Flooring is usually bought in whole boxes, so the calculator rounds the material area up to the next whole box.
Is this an installer measurement?
No. It is a general planning estimate and not a replacement for site measurement or installation advice.
