Flooring quantity calculator
Work out how many packs of laminate, engineered or vinyl click flooring to buy for a room, using the area and each pack's stated coverage.
Result
Packs required
How to use this tool
- Measure the floor area.
- Check the coverage per pack printed on your chosen flooring and enter it.
- Read the number of packs to order.
Assumptions
- Room area × (1 + waste%) is divided by the product's pack coverage and rounded up to whole packs. The editable 2.2m² default is illustrative, not a standard pack size; use the chosen product's packaging or manufacturer data.
- The area calculation does not determine offcuts. Room shape, laying direction, pattern and fitting instructions affect the required allowance.
Technical details: what the fields mean
- Floor area
floorAreaM2 - Total floor area, in square metres.
- Pack coverage (check the pack)
packCoverageM2 - Area one pack covers — this varies a lot by product, so check the pack itself.
- Waste allowance
wastePercent - Editable allowance for cuts and offcuts. The default is illustrative; select an amount for the room shape and laying pattern, using product or installer guidance.
Methodology
Packs = (area × (1 + waste%)) ÷ pack coverage, rounded up to a whole pack.
Worked example
18m² room, 2.2m² packs, 10% waste
Inputs: Floor area: 18 m², Pack coverage (check the pack): 2.2 m², Waste allowance: 10%
Result: 9 packs required
Practical guidance
- Buy all packs from the same batch — colour/finish can vary between production runs.
- Leave flooring to acclimatise in the room for 48 hours before fitting, as most manufacturers recommend.
Common mistakes
- Using a generic pack-coverage figure instead of the one on your actual product.
- Not adding extra waste for a room with alcoves or an irregular shape.
FAQs
How many packs of laminate flooring do I need for 18m²?
Using the illustrative 2.2m² per pack and 10% allowance gives 9 packs. Replace both assumptions with your product's stated coverage and an allowance appropriate to the room and laying pattern.
