How many 22-1/2" × 34-1/2" pieces can you cut from a 4×8 sheet?
You can cut 5 pieces of 22-1/2" × 34-1/2" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 84% of the sheet ends up in parts. Sizes like this are typical for face-frame base cabinet sides.
The layout is 4 parts run lengthwise and 1 is turned across to use the strip that's left. 84% is a solid yield for a single part size; 16% goes to kerf and offcut.
Kerf and grain
The 1/8" kerf doesn't cost a part here: 5 fit with or without it. There's still 13-3/8" × 22-1/2" left over after the last cut.
Rotation is doing real work. With the grain locked, so every part's 34-1/2" side runs along the sheet's 96" length, only 4 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 4 per sheet.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 1/8" | 5 · 84% | 4 · 67% |
| None (theoretical) | 5 · 84% | 4 · 67% |
How many sheets for a batch?
| Pieces needed | 4×8 sheets | Last sheet |
|---|---|---|
| 10 | 2 | full |
| 25 | 5 | full |
| 50 | 10 | 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.

Does grain direction change how many 22-1/2" × 34-1/2" pieces fit?

How many 4×8 sheets do I need for 25 pieces at 22-1/2" × 34-1/2"?
5 sheets. At 5 per sheet, the last one carries 5 parts and is full.
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 22-1/2" × 34-1/2" 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: 5), 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.
