How to calculate how much flooring you need
The formula
Flooring to buy = Floor area × (1 + waste %)
Always round up to the nearest pack or roll. The waste allowance covers cuts, offcuts and mistakes.
Which waste % should I use?
5% — LVP in a simple rectangular room. 10% — laminate, engineered hardwood or carpet, standard rooms. 15% — solid hardwood or diagonal lay. 20% — herringbone or complex patterns.
Do I need to add extra?
If the room has lots of alcoves, bay windows or angles, add an extra 5–10% on top of the type default. Better to have offcuts left over than run short mid-job.
Pro tip: Order all your flooring from the same production batch. Batches can vary slightly in colour and texture — mismatched batches are visible and hard to fix.
