How many 12" × 24" pieces can you cut from a 4×8 sheet?
You can cut 10 pieces of 12" × 24" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 62% of the sheet ends up in parts. Sizes like this are typical for shelves and drawer parts.
The layout is 3 parts run lengthwise and 7 are turned across to use the strip that's left. 62% is middling — 38% of the sheet is left over, so it pays to nest these together with other parts.
Kerf and grain
On paper the sheet holds 16, but that is the no-kerf answer. Two 24" parts add up to exactly the sheet's 48", so there is no room left for even one 1/8" saw cut between them. Cut the parts at 11-7/8" × 23-15/16" instead and you get all 16 back.
Rotation is doing real work. With the grain locked, so every part's 24" side runs along the sheet's 96" length, only 9 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 9 per sheet.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 1/8" | 10 · 62% | 9 · 56% |
| None (theoretical) | 16 · 100% | 16 · 100% |
How many sheets for a batch?
| Pieces needed | 4×8 sheets | Last sheet |
|---|---|---|
| 10 | 1 | full |
| 25 | 3 | 5 of 10 — room for 5 more |
| 50 | 5 | full |
Same 1/8" 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 12x24 pieces can you cut from a 4×8 sheet?
You can cut 10 pieces of 12" × 24" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 62% of the sheet ends up in parts. The layout is 3 parts run lengthwise and 7 are turned across to use the strip that's left.
Why only 10 and not 16?
On paper the sheet holds 16, but that is the no-kerf answer. Two 24" parts add up to exactly the sheet's 48", so there is no room left for even one 1/8" saw cut between them. Cut the parts at 11-7/8" × 23-15/16" instead and you get all 16 back.
Does grain direction change how many 12" × 24" pieces fit?
Rotation is doing real work. With the grain locked, so every part's 24" side runs along the sheet's 96" length, only 9 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 9 per sheet.
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 12" × 24" parts than could possibly fit on one 48" × 96" sheet, with a 1/8" 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: 10), so the page never shows less than a straight grid would give. No edge trim is assumed; if you skim 1/4" off a factory edge, re-run it in the optimizer with trim set.
