How many 300 × 500 mm pieces can you cut from a 2440 × 1220 mm sheet?
You can cut 18 pieces of 300 × 500 mm from one 2440 × 1220 mm sheet with a 3 mm saw kerf and rotation allowed — 91% of the sheet ends up in parts.
The layout is 16 parts run lengthwise and 2 are turned across to use the strip that's left. At 91% this is an efficient size for the sheet — under 10% goes to kerf and offcut.
Kerf and grain
The 3 mm kerf doesn't cost a part here: 18 fit with or without it. There's still 1220 × 125 mm left over after the last cut.
Rotation is doing real work. With the grain locked, so every part's 500 mm side runs along the sheet's 2440 mm length, only 16 fit — the other 2 come from turning parts across the sheet. That's fine for paint-grade plywood, MDF or melamine; for show faces with visible grain, plan on 16 per sheet.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 3 mm | 18 · 91% | 16 · 81% |
| None (theoretical) | 18 · 91% | 16 · 81% |
How many sheets for a batch?
| Pieces needed | 2440 × 1220 mm sheets | Last sheet |
|---|---|---|
| 10 | 1 | 10 of 18 — room for 8 more |
| 25 | 2 | 7 of 18 — room for 11 more |
| 50 | 3 | 14 of 18 — room for 4 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.
FAQ
How many 300x500 mm pieces can you cut from a 2440 × 1220 mm sheet?
You can cut 18 pieces of 300 × 500 mm from one 2440 × 1220 mm sheet with a 3 mm saw kerf and rotation allowed — 91% of the sheet ends up in parts. The layout is 16 parts run lengthwise and 2 are turned across to use the strip that's left.
Does grain direction change how many 300 × 500 mm pieces fit?
Rotation is doing real work. With the grain locked, so every part's 500 mm side runs along the sheet's 2440 mm length, only 16 fit — the other 2 come from turning parts across the sheet. That's fine for paint-grade plywood, MDF or melamine; for show faces with visible grain, plan on 16 per sheet.
How many 2440 × 1220 mm sheets do I need for 25 pieces at 300 × 500 mm?
2 sheets. At 18 per sheet, the last one carries 7 parts, leaving room for 11 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 300 × 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: 18), 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.
