Laminate floats, so the gap at the walls matters as much as the area. This also checks your last row width.
How it works
Area plus 10% ÷ carton coverage. Rows are room width less gaps ÷ plank width, and the leftover is your last row.
Before you order
- Rip the first row if the last row would be under about 2 in.
- Lay underlayment if the planks do not come with it attached.
- Keep the gap clear at door frames, so undercut the casings.
Common questions
Does laminate need an expansion gap?
Yes. Floating floors expand and contract, so leave the gap the maker specifies at walls and fixed objects.
Do I need underlayment?
Most laminate does unless the planks have a pad attached. Concrete floors also often need a moisture barrier.
