Honest material calculator

How much laminate you actually need

Laminate is a floating floor: it is not fixed down, and it expands and contracts with the room. Almost every laminate failure comes from that one fact being ignored — the gap around the edge, the underlay, or a floor run too far without a break.

Enter the room and the coverage printed on the pack. Then read the expansion gap section, which matters more than the pack count.

It is a floating floor, and that explains everything

Laminate is not fixed down. It expands and contracts with the room as a single sheet, and almost every laminate failure comes from that one fact being ignored. The gap around the edge is not optional trim detail — it is what stops the floor buckling in the first warm spell. Get the perimeter right and the rest of the job is straightforward.

The two mistakes that pin a floating floor

Beading fixes to the skirting or the wall, never to the floor. Pin it through into the laminate and you have clamped the floating floor to the wall. Nothing heavy sits on top of it — laminate should not be trapped under a fixed kitchen unit or a heavy appliance, because that pins it just as effectively. Decide where the floor stops before you start, rather than discovering the problem at the units.

Fitting details worth getting right

Acclimatise for 48 hours, packs laid flat in the room they will be fitted in — not stood on edge, not in a cold hallway. Undercut the doorframes rather than cutting boards around them: lay a scrap board flat, use it to set the height of a flush-cut saw, and slide the board under afterwards. Stagger end joints by 300 mm or more, using the offcut from the end of one row to start the next — it staggers naturally and wastes almost nothing, which is why the waste allowance can stay modest.

Questions people actually ask

Why does laminate flooring need an expansion gap?

Because it is a floating floor: it is not fixed down and it expands and contracts with the room as a single sheet. Without a gap at the perimeter it has nowhere to go and buckles. This is the cause of most laminate failures.

Can I fix beading through the laminate?

No. Beading pins to the skirting or the wall only. Fixing it through into the laminate clamps the floating floor in place, which defeats the whole system.

Should laminate go under kitchen units?

Generally not. A fixed unit or heavy appliance sitting on the floor pins it and stops it moving. Decide where the floor stops before you start laying, not when you reach the units.

How much should I stagger the end joints?

300 mm or more. Using the offcut from the end of one row to start the next staggers the joints naturally and wastes almost nothing.
