2440 × 1220 mm sheet at a glance
| Size | 2440 × 1220 mm |

| Area | 2.98 m² (32.0 sq ft) |

2440 × 1220 mm is 96.06 × 48.03 inches, so it is almost identical to a North American 4×8, and imperial project plans transfer directly. Work in millimeters for metric hardware and drawer runners: switch Units in the optimizer and every size converts.
A typical table saw blade removes about 3 mm, a track saw about 2.2–2.5 mm. Over a full board this adds up: four rips across 1220 mm cost 12 mm with a 3 mm blade, so four 300 mm strips fit but four 303 mm strips do not. The tables below include a 3 mm kerf.
Merchants and timber yards often offer a cut-to-size service on a panel saw. Export your layout as CSV, or print the cut diagrams, and the cutter has the exact sequence of rips and crosscuts.

How many parts fit on one sheet?
Calculated with the optimizer for a single sheet, 3 mm kerf and straight through-cuts. "Grain locked" keeps the part length along the sheet length; "rotation allowed" applies to MDF, melamine and hidden parts.
| Part | Size | Grain locked | Rotation allowed |
|---|---|---|---|
| Base cabinet side | 720 mm × 560 mm | 6 | 6 |
| Wall cabinet side | 720 mm × 300 mm | 12 | 12 |
| Shelf | 800 mm × 300 mm | 12 | 12 |
| Cabinet door | 715 mm × 397 mm | 9 | 9 |
| Drawer side | 500 mm × 150 mm | 28 | 34 |
| 600 × 600 panel | 600 mm × 600 mm | 8 | 8 |
