Standard Sheet Sizes by Country: Plywood, MDF, Chipboard and More

"A standard sheet" means 48 × 96 in in Ohio, 2440 × 1220 mm in Leeds, 2400 × 1200 mm in Brisbane, 2800 × 2070 mm for chipboard in Germany, and 2750 × 1850 mm in São Paulo. This table lists common sheet sizes by material, region and maker, in millimetres and inches. Every row links to the maker or retailer page that states it, checked on 2026-10-03. Each size has a button that opens the free nesting optimizer with that sheet loaded.

The bold column is the unit the source uses; the other is converted at 25.4 mm per inch. Sizes are width × length. Makers change ranges, so confirm with your supplier before ordering. Know a size we are missing? It goes in once there is a maker or retailer page that states it.

Nominal vs actual thickness

US plywood is sold by names that do not match a ruler. A sheet called "3/4 inch" usually measures 23/32" (0.719") after sanding (WoodWiki). APA treats 23/32 and 3/4, and 15/32 and 1/2, as separate performance categories (APA). Real sheets vary too: one CDX panel sold as 23/32" is listed at 0.688" (Supply On Time).

It matters for joinery, not layout. Sheet layout only cares about face size, but every part that fits between two sides is cut to the outside width minus two actual thicknesses. With 23/32" ply that is 1-7/16", not 1-1/2". Metric boards (UK MDF, Baltic birch, European chipboard) are sold by metric thickness (18 mm, 16 mm and so on), so measure those too, but the label is much closer to the board. The project plans on this site size every part from the actual thickness for this reason.

Why 2440 × 1220, not 2438 × 1219?

An exact 8 × 4 ft is 2438.4 × 1219.2 mm. Mills producing for metric markets round up to 2440 × 1220 mm and sell it as 4×8 / 8×4 (Liyuan Plywood, Plywoodetc). The difference is 1.6 mm in length and 0.8 mm in width. That is too little to matter for most cutting lists, but it explains why a US plan "fits exactly" with a little to spare on a UK sheet.

Baltic birch works the same way: an exact 60" is 1524 mm, and you will see both 1524 and 1525 mm quoted for "5×5" sheets.

Metric vs imperial sheets: what changes on a cutting list

  • "8×4" is not one size. Wood boards in the UK are 2440 × 1220 mm, Australian MDF is 2400 × 1200 mm, and UK sheet metal sold as "8ft × 4ft" is 2500 × 1250 mm. A layout made for one can fail on another: 40 mm of length is a whole part on a tight nest.
  • Big formats change the maths. A 2800 × 2070 mm chipboard sheet has almost twice the area of an 8×4, so a cutting list planned on 2440 × 1220 nests very differently on it. Re-run the layout at the real size.
  • Kerf is the same everywhere. Two equal rips from 1220 mm with a 3 mm blade give 608.5 mm each, and from 48" with a 1/8" blade, 23-15/16". The 8x4 sheet cutting calculator walks through a metric example.

FAQ

What is the standard size of a sheet of plywood?

In the US and Canada, 4 × 8 ft (48 × 96 in). In the UK and Ireland, plywood and MDF are sold as 2440 × 1220 mm, the metric "8×4". Europe also uses 2500 × 1250 mm for plywood and OSB, and Baltic birch commonly comes 5 × 5 ft (1525 × 1525 mm).

What size are MDF sheets?

It depends on the country. US MDF is 4 × 8 ft, often supplied oversized at 49 × 97 in. UK MDF is 2440 × 1220 mm (and 3050 × 1220 mm). Australian MDF is commonly 2400 × 1200 mm, and South African and Kenyan MDF is commonly 2750 × 1830 mm. Brazilian MDF is 2750 × 1850 mm.

Is 2440 × 1220 the same as 8 × 4 feet?

Nearly. An exact 8 × 4 ft is 2438.4 × 1219.2 mm. Boards sold in metric markets as "8×4" are made to the round figure of 2440 × 1220 mm, so they are about 1.6 mm longer and 0.8 mm wider than an exact 96 × 48 in.

How thick is 3/4 inch plywood really?

Usually 23/32" (about 0.72", or 18.3 mm). US structural panels are labelled by performance category, and measured thickness varies by product: one CDX "23/32" sheet is listed at 0.688". Baltic birch sold as "3/4"" is 18 mm. Measure before you cut dadoes.

What size is a chipboard or melamine (MFC) sheet in Europe?

Commonly 2800 × 2070 mm for melamine-faced chipboard from makers like Egger and Kronospan, in 15, 18 and 25 mm. That is almost twice the area of an 8×4, so re-run any layout planned for 2440 × 1220 at the real sheet size before ordering.
