How many 48" × 48" pieces can you cut from a 4×8 sheet?

You can cut 1 piece of 48" × 48" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 50% of the sheet ends up in parts. Sizes like this are typical for half-sheet panels.

The layout is a single part, with the rest of the sheet left as offcut. Only 50% 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

On paper the sheet holds 2, but that is the no-kerf answer. Two 48" parts add up to exactly the sheet's 96", so there is no room left for even one 1/8" saw cut between them. Cut the parts at 47-15/16" × 47-15/16" instead and you get all 2 back.

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 1.

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 48x48 pieces can you cut from a 4×8 sheet?

You can cut 1 piece of 48" × 48" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 50% of the sheet ends up in parts. The layout is a single part, with the rest of the sheet left as offcut.

Why only 1 and not 2?

On paper the sheet holds 2, but that is the no-kerf answer. Two 48" parts add up to exactly the sheet's 96", so there is no room left for even one 1/8" saw cut between them. Cut the parts at 47-15/16" × 47-15/16" instead and you get all 2 back.

How many 4×8 sheets do I need for 25 pieces at 48" × 48"?

25 sheets. At 1 per sheet, the last one carries 1 part 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 48" × 48" 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: 1), 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.
