How many 500 × 500 mm pieces can you cut from a 2440 × 1220 mm sheet?
You can cut 8 pieces of 500 × 500 mm from one 2440 × 1220 mm sheet with a 3 mm saw kerf and rotation allowed — 67% of the sheet ends up in parts.
The layout is a straight grid, 2 across and 4 along the length. 67% is middling — 33% 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: 8 fit with or without it. There's still 214 × 2440 mm left over after the last cut.
Squares don't care about rotation, so grain direction is free: lay every piece with the grain running the 2440 mm length and the count stays at 8.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 3 mm | 8 · 67% | 8 · 67% |
| None (theoretical) | 8 · 67% | 8 · 67% |
How many sheets for a batch?
| Pieces needed | 2440 × 1220 mm sheets | Last sheet |
|---|---|---|
| 10 | 2 | 2 of 8 — room for 6 more |
| 25 | 4 | 1 of 8 — room for 7 more |
| 50 | 7 | 2 of 8 — room for 6 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.

How many 2440 × 1220 mm sheets do I need for 25 pieces at 500 × 500 mm?
4 sheets. At 8 per sheet, the last one carries 1 part, leaving room for 7 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 500 × 500 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: 8), 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.
