Standard flooring plank sizes: laminate, LVT and wood board dimensions

The standard laminate plank is 1,280 to 1,380 mm (about 50 to 54 in) long by 190 to 245 mm (about 7.5 to 9.5 in) wide; LVT runs a little shorter and narrower, and engineered wood stretches past 2 m (about 6.5 ft). Plank size looks like an aesthetic choice, but it's the third input, alongside your room and your pattern, that determines every row, cut and offcut in the layout. Two ranges at the same price per m² can produce visibly and financially different floors in the same room, purely through their dimensions.

What's on the shelves

Pack coverage follows size: standard laminate packs cover about 1.6 to 2.5 m² (about 15 to 25 sq ft) (usually 7 to 9 boards); wide engineered packs sometimes barely 1.5 m². The number matters for the pack maths, so never assume it, read it off the pack.

How length changes the layout

Row arithmetic: room length ÷ board length. The remainder is the end-cut, and the end-cut is the offcut that starts later rows:

• Good multiples produce offcuts near half a board, which make ideal starters.
• Bad multiples (room length just over a whole number of boards) produce stubs under the minimum piece length every single row, which are un-reusable, so waste climbs quietly by several percent.
• Longer boards make longer offcuts on average, but also lose more per discarded piece. The effect depends on your room, which is exactly the kind of arithmetic worth checking in a layout before buying.

Length also gates the stagger: the minimum joint offset (200 to 300 mm, about 8 to 12 in) is a bigger fraction of a short board, so short-board ranges support fewer bond fractions.

How width changes the layout

Room width ÷ board width sets the row count and the remainder that becomes the last-row rip:

• Narrow boards (≤200 mm, about 8 in): more rows, finer granularity, so the remainder is easier to split into two healthy edge rows.
• Wide boards (≥240 mm, about 9.5 in): fewer rows, calmer floor, but the remainder swings bigger, and a bad split costs a wide, expensive rip. In narrow rooms wide boards can end up as two rips and one full row, which looks exactly as unplanned as it is. Whether that trade is worth making room by room is the subject of the wide vs narrow decision guide.

Pattern formats are stricter

Herringbone, basketweave and windmill require the length to be an exact multiple of the width: 5× for a 600 × 120 mm (about 24 x 4.75 in) herringbone board, 2 to 5× for the block patterns. A range that's a few millimetres off doesn't close. The pattern pages list the requirement per pattern; check it before falling for a decor.

Try the size before you buy the size

We measured exactly that spread: laying 250 rooms in six plank widths put a 94 mm (about 3.7 in) strip at 5.7% waste and a 305 mm (about 12 in) plank at 10.2%, with the penalty concentrated in small rooms and hallways. Since the same room can waste 5% with one format and 10% with another, the cheapest hour of the project is testing your shortlisted ranges against your actual room: enter each board size in the designer and compare pack counts and last-row widths side by side. The cost guide shows what those few percent are worth in money.
