How many 400 × 600 mm pieces can you cut from a 2440 × 1220 mm sheet?

You can cut 12 pieces of 400 × 600 mm from one 2440 × 1220 mm sheet with a 3 mm saw kerf and rotation allowed — 97% of the sheet ends up in parts.

The layout is a straight grid, 2 across and 6 along the length, every part turned across the sheet. At 97% this is an efficient size for the sheet — under 4% goes to kerf and offcut.

Kerf and grain

The 3 mm kerf doesn't cost a part here: 12 fit with or without it.

Grain direction costs nothing here: with every part's 600 mm side running along the sheet's 2440 mm length you still get 12, so you can keep the grain consistent for free.

FAQ

How many 400x600 mm pieces can you cut from a 2440 × 1220 mm sheet?

How many 2440 × 1220 mm sheets do I need for 25 pieces at 400 × 600 mm?

3 sheets. At 12 per sheet, the last one carries 1 part, 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 400 × 600 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: 12), 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.
