Assembly tip

Dry-fit before gluing. Pocket screws (Kreg jig) make assembly fast and strong. Measure both diagonals after assembly — they should match to confirm the box is square.

A full plywood cut list for a base, wall, or tall cabinet — every panel, sized and squared, so you can cut a whole carcass without stopping to do arithmetic.

How it works

The carcass is built from standard proportions: base cabinets are 34 1/2 inches tall (so the countertop lands at 36) and 24 inches deep; wall cabinets are typically 12 to 14 inches deep. From your overall dimensions the tool subtracts the material thickness where panels overlap, so the sides, top, bottom, and back come out to sizes that actually assemble square.

Example

A 30-inch-wide base cabinet from 3/4-inch plywood: two sides at 34 1/2 × 24 inches, with the bottom and stretchers cut to 28 1/2 inches — the full 30 minus the thickness of both sides.

Tips & common mistakes

Frequently asked questions

What are standard kitchen cabinet dimensions?

Base cabinets are 34 1/2 inches tall and 24 inches deep, which puts the finished countertop at 36 inches. Wall cabinets are usually 12 to 14 inches deep, hung 18 inches above the counter.

What plywood thickness for cabinets?

3/4-inch for the carcass sides, top, and bottom; 1/4 or 1/2-inch is plenty for the back. Remember that nominal 3/4-inch plywood actually measures about 23/32.

How much plywood do I need for one cabinet?

Roughly one 4×8 sheet for a typical 30-inch base cabinet, depending on how efficiently you lay out the cuts. The cut optimizer will tell you exactly.
