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

You can cut 55 pieces of 8" × 8" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 76% of the sheet ends up in parts. Sizes like this are typical for small boxes and trivets.

The layout is a straight grid, 5 across and 11 along the length. 76% is a solid yield for a single part size; 24% goes to kerf and offcut.

55 × 8" × 8" on a 4×8 sheet (48" × 96"), 1/8" kerf, rotation allowed. Dashed: largest offcut, a full-length 7-3/8"-wide rip (7-3/8" × 96").

Kerf and grain

On paper the sheet holds 72, but that is the no-kerf answer. Six 8" 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 7-7/8" × 7-7/8" instead and you get all 72 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 55.

FAQ

How many 8x8 pieces can you cut from a 4×8 sheet?

You can cut 55 pieces of 8" × 8" from one 4×8 sheet (48" × 96") with a 1/8" saw kerf and rotation allowed — 76% of the sheet ends up in parts. The layout is a straight grid, 5 across and 11 along the length.

Why only 55 and not 72?

On paper the sheet holds 72, but that is the no-kerf answer. Six 8" 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 7-7/8" × 7-7/8" instead and you get all 72 back.

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

1 sheet. At 55 per sheet, the last one carries 25 parts, leaving room for 30 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 8" × 8" 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: 55), 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.
