- Save money – buy exactly what you need, no more, no less

Understanding Flooring Measurements
Laminate and wood flooring is typically sold by the square metre (m²) and comes in packs. Each pack covers a certain area — often around 2-3 m².
When calculating how much flooring you need, consider:
- Room dimensions – length and width
- Plank size – larger planks may have less wastage
- Wastage allowance – for cuts, fitting, and mistakes
Always add a wastage allowance of at least 10% for irregular room shapes and fitting errors.

- Living room (5m x 4m): 20 m² (requires 7 packs of 3m²)

These are estimates – always use the flooring calculator for an accurate measurement for your specific room.
