Laminate Flooring Calculator — How Many Packs Do I Need?
Enter your room dimensions and pack coverage to calculate exactly how many packs to order, including waste allowance and leftover from the final pack.
How many packs of laminate flooring do I need?
Measure room length x width to get the area in m². Add your waste allowance, usually 10% for straight lay. Divide by the pack coverage in m² and round up to the nearest whole pack. Always round up - never down.
How much waste should I allow for laminate?
Use 10% for straight or parallel lay in a simple room. Use 15% for diagonal or 45° lay because angled cuts at walls waste significantly more material. Use 20% for herringbone or complex patterns. Add an extra 5% if your room has many obstacles like a fireplace, bay window or fitted units.
What does pack coverage mean?
Every pack of laminate states a coverage figure in m² or sq ft on the label. This is the total floor area one pack will cover when laid. Pack sizes vary by brand and plank size - always check the label rather than assuming.
How to measure a room for laminate flooring
Measure the longest length and the widest width, including any alcoves or bay windows. For L-shaped rooms, split into two rectangles and add the areas together before calculating packs. Always measure in the direction you plan to lay the planks.
What to do with leftover laminate
Always keep offcuts from the final pack. Store them flat in a dry place. They are invaluable for future repairs if a plank gets damaged - and replacement packs from the same batch are often impossible to match exactly years later.

Laminate calculator FAQ
Frequently Asked Questions
How do I calculate how many packs of laminate I need?
Measure your room area (length x width), add 10% for waste, then divide by the pack coverage in m² and round up. For example, a 4m x 5m room is 20m². With 10% waste that is 22m². At 2.47m² per pack you need 9 packs.
How much extra laminate should I buy?
Buy 10% extra for straight lay. Buy 15% extra for diagonal lay. Buy 20% extra for herringbone. Always round up to whole packs - never buy fewer packs than the calculator recommends.
What happens to leftover laminate?
Keep all offcuts and store them flat in a dry location. Use them for future repairs. Matching the exact same batch years later is often impossible, so leftover material is valuable.
How do I find the pack coverage for my laminate?
The coverage in m² or sq ft is printed on every pack label. It varies by brand and plank size. Always use the figure from your specific pack rather than a generic estimate.
