How many 11-1/4" × 30" pieces can you cut from a 4×8 sheet?
You can cut 12 pieces of 11-1/4" × 30" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 88% of the sheet ends up in parts. Sizes like this are typical for 12"-deep, 30"-tall wall cabinet sides.
The layout is a straight grid, 4 across and 3 along the length, long sides running with the sheet. 88% is a solid yield for a single part size; 12% goes to kerf and offcut.
Kerf and grain
The 1/8" kerf doesn't cost a part here: 12 fit with or without it. There's still 48" × 5-5/8" left over after the last cut.
Grain direction costs nothing here: with every part's 30" side running along the sheet's 96" length you still get 12, so you can keep the grain consistent for free.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 1/8" | 12 · 88% | 12 · 88% |
| None (theoretical) | 12 · 88% | 12 · 88% |
How many sheets for a batch?
| Pieces needed | 4×8 sheets | Last sheet |
|---|---|---|
| 10 | 1 | 10 of 12 — room for 2 more |
| 25 | 3 | 1 of 12 — room for 11 more |
| 50 | 5 | 2 of 12 — room for 10 more |
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 11-1/4x30 pieces can you cut from a 4×8 sheet?

How many 4×8 sheets do I need for 25 pieces at 11-1/4" × 30"?
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 11-1/4" × 30" 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: 12), 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.
