Net floor area.
Measure each room separately and add — an L-shaped space wastes more than its area suggests because the run has to break.
Area covered per pack, from the label.
From the label, because it changes with the plank size and it is the only figure that turns an area into packs. It is a NOMINAL coverage and does not allow for the offcut at the end of each row — in a narrow room, where few planks fit across, that offcut can amount to most of a plank per row and the waste allowance has to carry it. Rooms with many doorways and returns waste more again.
Complexity drives the offcut you cannot reuse.
In a click floor the end offcut from one row usually starts the next, which keeps a simple room efficient. Every alcove, angle and doorway breaks that chain — and a diagonal lay breaks it on every row.
Packs required
13 packs
Keep a full pack spare. A damaged plank in a click floor is replaced by lifting back to it, and a batch-matched board is the only invisible repair.

How this was calculated
Formula source(s)
- Manufacturers typically specify 5-10% waste for a straight lay, and 15% or more for a diagonal lay or a room with many angles
- Expansion gap of 8-12 mm at every perimeter and fixed obstruction — standard click-system installation instruction

What this calculation does not cover
- Nothing caps the size of the floating field. Click systems carry a manufacturer maximum for one continuous run — commonly around 10 to 12 m (33 to 40 ft) in either direction, and a break at every doorway regardless — past which an expansion joint and a T-profile are required. An open-plan floor entered as a single area returns the packs for it and shows none of the profiles, none of the doorway breaks, and none of the extra part-rows that start again on the far side of each one.
- Plank length never enters the arithmetic, and it is what decides whether the offcut chain the waste bands assume actually closes. The tail cut off one row starts the next only if it beats the manufacturer's minimum starting piece — commonly 300 mm — and only if it holds the end-joint stagger from the row below, usually 300 mm or a third of a plank. A room whose width in the plank direction lands just past a whole number of planks throws that tail away on every single row, and 7% will not cover it.

Tools and safety for this job
To lay click-lock flooring. Generic types, no brands, no prices.
Protection this work requires
- Hardwood dust is a recognised carcinogen: extract at the tool and wear a P2/N95 respirator when cutting or sanding indoors.
- Saws, grinders and breakers run above 85 dB, where hearing damage accumulates and does not recover: defenders or plugs for every cut, not just the long ones.
- Knives cause more site injuries than any power tool: cut away from your body, change blades often, and wear cut-resistant gloves to EN 388 level C for repeated cutting.
