Plywood sheet cut list: ripping a 4×8 sheet into 12-inch strips
Ripping 12-inch strips with a 0.125 inch kerf gives 3 strips per 48-inch-wide sheet, because 4 strips need 48.375 inches. The parts pack onto 4 strips, so buy 2 sheets (4 strips / 3 per sheet, rounded up).
Layout assumptions
KerfCount packs lengths, so plywood is planned in two steps. First rip the 4×8 sheet into 12-inch-wide strips 96 inches long. Then pack the part lengths onto those strips. Every part in this example is 12 inches wide: four shelves and two back cleats at 30 inches, and two sides at 60 inches (the same lengths as the 32-inch bookshelf example).
This is a one-direction plan. It does not nest parts of different widths on the sheet, and it ignores edge trim, grain direction, and sheet defects.
Strips needed: cut assignments
| Board | Parts | Cut lengths | Remaining offcut |
|---|---|---|---|
| 1 | Side panel, Shelf | 60 + 30 in | 5.25 in |
| 2 | Side panel, Shelf | 60 + 30 in | 5.25 in |
| 3 | Shelf, Shelf, Back cleat | 30 + 30 + 30 in | 5.125 in |
| 4 | Back cleat | 30 in | 65.375 in |
4 boards, 78.1% of the wood used, 81 in of offcut.
