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
Plywood is not the thickness it claims. '3/4-inch' sheet is usually about 23/32, and that missing 1/32 will throw off every joint if you build to the nominal number. Measure your actual sheet and use that.
Cut all the same-size parts at one time, from one saw setting. Re-setting the fence between two identical pieces is how you end up with a cabinet that is 1/16 out of square.
Label every panel the moment you cut it. Plywood rectangles look identical on the floor, and sorting them out later costs more time than labeling cost.
Check the diagonals when you assemble. If the two diagonal measurements match, the box is square — and a square box is the difference between doors that close and doors that fight you forever.
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.
