How many 36" × 36" pieces can you cut from a 4×8 sheet?
You can cut 2 pieces of 36" × 36" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 56% of the sheet ends up in parts. Sizes like this are typical for tabletops.
The layout is a straight grid, 1 across and 2 along the length. Only 56% of the sheet becomes parts. This size leaves a lot of sheet behind: nest it alongside other parts, or tweak the size if the design allows.
Kerf and grain
The 1/8" kerf doesn't cost a part here: 2 fit with or without it. There's still 48" × 23-3/4" left over after the last cut.
Squares don't care about rotation, so grain direction is free: lay every piece with the grain running the 96" length and the count stays at 2.
| Saw kerf | Rotation allowed | Grain-locked (no rotation) |
|---|---|---|
| 1/8" | 2 · 56% | 2 · 56% |
| None (theoretical) | 2 · 56% | 2 · 56% |
How many sheets for a batch?
| Pieces needed | 4×8 sheets | Last sheet |
|---|---|---|
| 10 | 5 | full |
| 25 | 13 | 1 of 2 — room for 1 more |
| 50 | 25 | 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.

How many 4×8 sheets do I need for 25 pieces at 36" × 36"?
13 sheets. At 2 per sheet, the last one carries 1 part, leaving room for 1 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 36" × 36" 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: 2), 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.
