21mm Plywood — Area Coverage & Sheets Needed
A standard 1220×2440mm (4'×8') sheet of 21mm plywood covers 2.9768 square meters (32.04 sq ft). To cover 10 m², you need 4 sheets. For 50 m², you need 17 sheets. For 100 m², you need 34 sheets. Coverage is the same regardless of plywood thickness — only panel dimensions matter.
21mm Plywood — Area Coverage & Sheets Needed
How many sheets you need to cover a given area. Add 5–10% for cuts and wastage.
| Panel Size (mm) | m²/Sheet | For 10 m² | For 50 m² | For 100 m² |
|---|---|---|---|---|
| 1220 × 2440 | 2.9768 | 4 sheets | 17 sheets | 34 sheets |
| 1250 × 2500 | 3.1250 | 4 sheets | 16 sheets | 32 sheets |
| 610 × 2440 | 1.4884 | 7 sheets | 34 sheets | 68 sheets |
| 625 × 2500 | 1.5625 | 7 sheets | 32 sheets | 64 sheets |

▶How many square meters does one sheet of 21mm plywood cover?
One 1220×2440mm (4'×8') sheet covers 2.9768 m² (32.04 sq ft). For Euro-size 1250×2500mm panels, coverage is 3.1250 m².
▶How many 21mm plywood sheets do I need for 100 square meters?
You need 34 sheets of 1220×2440mm plywood to cover 100 m². For 50 m²: 17 sheets. For 10 m²: 4 sheets. Always add 5-10% waste factor for cuts and offcuts.
▶How many square feet does a sheet of plywood cover?
A standard 1220×2440mm (4'×8') plywood sheet covers 32.04 square feet (2.9768 m²). This applies to all plywood thicknesses including 21mm — coverage depends only on panel width and length.
▶Does plywood thickness affect area coverage?
No. Area coverage depends only on panel width and length, not thickness. A 21mm sheet and an 18mm sheet of the same 1220×2440mm size both cover 2.9768 m². However, thickness affects volume (CBM), weight, and cost.
