What you need to know
- Measure the actual floor area.
- Add a waste allowance based on layout and room complexity.
- Divide by pack coverage and round up to complete boxes.
Use your own measurements
BricoDato tools help turn the guide into quantities, kWh, cost or a project plan.
Start with net floor area
Multiply length by width for simple rooms and split irregular spaces into smaller rectangles. Exclude only areas where flooring definitely will not be installed.
Add waste before converting to boxes
Offcuts, damaged boards and layout choices mean you need more than the geometric floor area. The correct margin depends on room shape and installation direction.
Use pack coverage
Manufacturers state the square metres per pack. Divide the required area including waste by that figure and round up.
Think beyond the boards
Underlay, vapour control, skirting, profiles and subfloor preparation can add meaningful cost to the project.
Final check
Before buying material or doing the work, review the assumptions and technical limits that matter for your specific product, room or installation.
- Confirm net floor area.
- Set a waste margin for the real layout.
- Use the exact pack coverage.
- Keep one or more boards for future repairs when practical.
Keep a small job sheet
Record the measurements, product reference, technical values you used, date and final result. For maintenance or diagnostics, also note the conditions at the time. A short written record makes future comparisons much more reliable.
Turn the guide into a decision
Use your measurements and the manufacturer’s technical data. If the decision affects fixed electrical work, structure, hidden leaks, refrigerant systems or another safety-critical installation, consult a qualified professional.
