Flooring calculator
A solid start, from the floor up. Plan your flooring, with room for the offcuts.
Your measurements
How this calculation works
A worked example
A 4 × 3 m floor is 12 m². With 10% allowance, plan for 13.2 m². At 2.2 m² per box, buy exactly 6 boxes.
Before you buy
Use effective coverage from the box label, not nominal plank size. Pattern presets are editable planning assumptions. This calculator counts boxes; it does not optimize individual plank cuts. Underlay, trims, expansion gaps and subfloor preparation must be planned separately.
A few useful answers
Can I combine rooms?
Use the Room Area calculator to measure them first. Add separate flooring entries to your project for rooms or products with different requirements.
Are my results saved?
Use Add to project to keep material estimates in your browser. You can copy results or print them at any time. No account or remote project storage is used.
Are the defaults product recommendations?
No. They are transparent example assumptions. Replace coverage, sizes, prices and allowances with your actual product details.
