Which plywood, and how many sheets
Plywood is graded by what its glue and its face can survive, not by how it looks. The four types here are genuinely different products and substituting down is how a pour goes wrong or a fit-out warps.
| Sheet | Area | Sheets per 100 m² | Common thicknesses |
|---|---|---|---|
| 1220 × 2440 mm | 2.98 m² | 34 | 3, 4, 6, 9, 12, 15, 18, 25 mm |
One standard sheet covers 2.98 m². Divide your area by that and round up — allow extra for cuts and waste on anything but a simple rectangle. Film-faced is also stocked in 21 mm; flexible runs 3, 5, 8 and 12 mm.
- Commercial — general joinery, boxing, partitions and site carpentry. The everyday board.
- Film-faced (shuttering) — a phenolic film on both faces so the board releases from concrete and can be struck and reused. For formwork.
- Marine — bonded to survive damp and repeated wetting, for boats, wet areas and anywhere exposure is real.
- Flexible (bendy) — cut so it will curve, for curved joinery and column casings.
The arithmetic most enquiries need
4,000 m² of boarding is 4,000 ÷ 2.98 = 1,343 sheets before waste. Working the other way, 3,000 sheets covers about 8,930 m². Send us the area and we will do it with you rather than quoting a per-sheet price against a number you had to guess.
