Vinyl Plank Flooring Calculator

Cartons = floor area plus extra ÷ the coverage on the carton, rounded up: a 12 × 10 ft room in 48 × 6 in planks is 120 sq ft, or 7 cartons of 20 sq ft with 10% extra.

Your measurements

Example

Use the unit shown for each box, or type another one: 12 ft 6 in, 150 in, 3.8 m and 600 mm all work, as do the marks on a tape measure.

Room 1

Room length (ft) Room width (ft) Area left uncovered (sq ft) Surface shape An L-shaped room is a rectangle with one corner missing. Measure the overall length and width, then the missing corner.

Extra for cuts (%) Extra is added to both the area order and the separate cut-layout allowance. Check the direction, alternating offset and carton coverage first. Adhesive is counted separately when you choose a glued installation. Installation method

First room, rotated so planks run across the drawing. Rows show the entered widths and alternate start offset. Large layouts draw the first 1,800 positions. Cuts consume one plank each; no offcut reuse is assumed.

Area cartons and the conservative cut allowance answer different questions. L-shaped corners are removed from the cutting layout. Other exclusions affect area only; split rooms around obstacles for a cutting layout.

The calculation

120 × (1 + 10/100) ÷ 20, rounded up = 7
Cut allowance: 70 plank positions with 20 sq ft offcut; no reuse assumed.

Common questions

Should vinyl plank be floating or glued down?

The product and the floor under it decide; the maker’s instructions say which methods are allowed. Choose the method in the calculator: adhesive is counted only for glue-down.

How much adhesive do I need?

Divide the floor area by the coverage on the adhesive label. That coverage depends on the trowel the label names.

How many boxes of vinyl plank do I need?

Add the rooms, add your extra for cuts and divide by the square feet on the carton, rounding up. The cut layout gives a second figure that counts each cut plank as whole.

How to plan the quantity

A floating floor and a glue-down floor can use the same room dimensions but require different supplies. Adhesive is calculated only in glue-down mode and only from the coverage you provide.

The drawing uses your plank direction and alternating row offset. A cut piece consumes a full plank in the conservative cut allowance; do not assume an end offcut has the right locking edge for another position.

Cartons round after rooms are combined. Keep different products or colors on separate receipts.

For an L-shaped floor, enter the widest length and width, then the size of the missing top-right corner. The plank layout removes that corner in either plank direction and allows the perimeter gap at its inner edges. Other excluded areas affect the area order only.

Before you order

No adhesive, substrate, moisture limit or expansion gap is selected by this tool.
The area-only exclusion changes cartons, not the drawing: split around a large obstacle when you need a cutting plan.

Before ordering, read the guide: How much flooring do I need? Square feet, boxes and waste. Or choose another calculator.
