How much LVT do I need for a 15 m² room?

With a straight lay and 8% waste you need 16.2 m². At a pack coverage of 2.1 m² that is 16.2 ÷ 2.1 = 7.7, so 8 packs. For herringbone LVT allow 18% waste, which comes to 17.7 m², or 9 packs.

Do I need more waste for LVT tiles than planks?

Not usually. Tile layouts like stack bond or brick bond waste about the same as a straight plank lay. The pattern drives the waste, not the format, so herringbone planks waste far more than either.

LVT flooring calculator

Enter your room dimensions and this calculator turns them into m² and whole packs of LVT, with a waste allowance matched to your laying pattern. Luxury vinyl planks and tiles are sold by the pack like laminate, so the maths is the same. Only the typical pack coverage differs.

LVT packs usually cover between 1.8 and 2.5 m² for planks, and a little more for tiles. Check the label and enter the exact figure, because pack sizes vary more between LVT ranges than between laminate ranges.

Packs to buy

This is the estimate. The designer lays out every board in your actual room, so the pack count comes from real cuts, not a flat percentage.

Rigid vs glue-down changes the waste, not the maths

Click-fit rigid LVT wastes like laminate, because offcuts can start the next row. Glue-down ranges let you use offcuts almost anywhere, so you can sit at the lower end of each waste range.

Herringbone LVT is popular, so budget for it

Many LVT ranges sell dedicated herringbone planks. If that is your plan, switch the pattern selector: the waste allowance jumps to 15% to 20%, and skipping that adjustment is the most common LVT ordering mistake.

Door bars and trims are extra

The calculator covers the floor area only. Thresholds, edge trims and scotia come on top, so count doorways and exposed edges separately.
