How many 700 × 900 mm pieces can you cut from a 2440 × 1220 mm sheet?
You can cut 3 pieces of 700 × 900 mm from one 2440 × 1220 mm sheet with a 3 mm saw kerf and rotation allowed — 63% of the sheet ends up in parts.
The layout is a straight grid, 1 across and 3 along the length, every part turned across the sheet. 63% is middling — 37% of the sheet is left over, so it pays to nest these together with other parts.
Kerf and grain
The 3 mm kerf doesn't cost a part here: 3 fit with or without it. There's still 1220 × 331 mm left over after the last cut.
Rotation is doing real work. With the grain locked, so every part's 900 mm side runs along the sheet's 2440 mm length, only 2 fit — the extra one comes from turning a part across the sheet. That's fine for paint-grade plywood, MDF or melamine; for show faces with visible grain, plan on 2 per sheet.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 3 mm | 3 · 63% | 2 · 42% |
| None (theoretical) | 3 · 63% | 2 · 42% |
How many sheets for a batch?
| Pieces needed | 2440 × 1220 mm sheets | Last sheet |
|---|---|---|
| 10 | 4 | 1 of 3 — room for 2 more |
| 25 | 9 | 1 of 3 — room for 2 more |
| 50 | 17 | 2 of 3 — room for 1 more |
Same 3 mm kerf, rotation allowed. A part-filled last sheet is the place to nest drawer bottoms, shelves or anything else from the same material.

Does grain direction change how many 700 × 900 mm pieces fit?
Rotation is doing real work. With the grain locked, so every part's 900 mm side runs along the sheet's 2440 mm length, only 2 fit — the extra one comes from turning a part across the sheet. That's fine for paint-grade plywood, MDF or melamine; for show faces with visible grain, plan on 2 per sheet.
How many 2440 × 1220 mm sheets do I need for 25 pieces at 700 × 900 mm?
9 sheets. At 3 per sheet, the last one carries 1 part, leaving room for 2 more.
How this was worked out
EZNESTING's nesting engine (the same one the optimizer runs, in its default least-waste guillotine mode) was given more 700 × 900 mm parts than could possibly fit on one 1220 × 2440 mm sheet, with a 3 mm kerf between parts and none at the factory edges. The parts it placed are the answer. That count is checked against simple grid layouts in both orientations (best of those: 3), so the page never shows less than a straight grid would give. No edge trim is assumed; if you skim 5 mm off a factory edge, re-run it in the optimizer with trim set.
