Standard Kitchen Cabinet Dimensions for Shops and Specs
Cutlistor Team4 min read
Introduction
Standard kitchen cabinet dimensions keep manufacturers, custom shops, appliance brands, and installers on the same grid. Even fully custom shops quote against these norms because dishwashers, sinks, and countertops assume them. Knowing the standards speeds takeoffs and prevents cut lists built to one-off sizes that fight the rest of the kitchen.
This reference is written for cabinet makers and estimators. It covers common North American sizes with metric approximations, notes where custom work should deviate, and links into cut list and nesting practice.
For depth and height focus only, see standard cabinet depths and heights. For how to turn these into panels, see the calculation guide.
Base Cabinet Standards
| Dimension | Common standard | Metric approx. | Notes |
|---|---|---|---|
| Carcase height | 34.5 in | 876 mm | Before countertop |
| Finished counter height | ~36 in | ~914 mm | Depends on top thickness |
| Carcase depth | 24 in | 610 mm | Doors add in front |
| Toe kick height | ~3 in | ~76 mm | Shop variance OK |
| Toe kick depth | ~3 in | ~76 mm | Recess from face |
| Width modules | 9–48 in (3 in steps) | 230–1220 mm | Stock cabinetry heritage |
Wall Cabinet Standards
| Dimension | Common standard | Metric approx. | Notes |
|---|---|---|---|
| Depth | 12 in | 305 mm | Plus door |
| Height (common) | 30 or 42 in | 762 or 1067 mm | 42 in for taller ceilings |
| Width modules | 9–48 in typical | 230–1220 mm | Match base rhythm when possible |
| Above counter gap | ~18 in | ~457 mm | Job-specific |
Tall and Pantry Standards
Tall cabinets and pantries commonly finish at 84, 90, or 96 in (2134, 2286, or 2438 mm) to align with door tops and ceiling treatments. Depth may match bases (24 in) or sit shallower for pantry pullouts.
Sheet stock length becomes a nesting constraint: a 96 in gable on 96 in sheet leaves no margin for kerf or square-up. Plan splits or orientation before you promise a seamless tall gable.
Appliance-Related Clearances
Standards exist so appliances fit. Always verify the specific unit.
- Dishwasher: typically fits a 24 in wide opening; check actual unit and adjacent fillers
- Range: 30 in nominal common; measure freestanding vs slide-in counter requirements
- Fridge: panels and depths vary widely; do not assume 24 in base depth
- Microwave / wall oven cabinets: follow manufacturer cutout sheets, not kitchen folklore
- Sink base: bowl and faucet geometry drive width more than door style
Custom Shops vs Stock Grids
Custom does not mean ignore standards. It means you can leave the 3 in grid when the room demands it, while still targeting 36 in counters and 24 in bases so stone templates and appliances behave.
When you leave the grid, update the cut list and nest immediately. Odd widths are fine; undocumented odd widths are how drawers get built twice.
Metric Markets and Import Specs
European frameless work often uses 720 mm carcase heights for bases (with legs/plinths making finished height), 600 mm depths, and 350 mm or 300+ mm wall depths depending on the market. If you build to an import drawing, do not silently convert to 34.5 / 24 / 12 without checking appliance and counter assumptions.
Nesting stock may be 2800 x 2070 mm boards. Recalculate yield; do not reuse a 4x8 nest habit.
From Standards to Cut List
Use standards to set overall W x D x H on the elevation. Calculate finished panels with your joinery rules. Nest with kerf for sheet count. Fillers absorb wall-to-wall remainder.
Cutlistor does not replace your standards library; it nests the rectangles those standards produce. Free browser nesting supports quoting before you buy melamine or plywood.
FAQ
Is a 36 in counter height mandatory?
It is the common NA target, not a law. Accessibility and client preference may call for other heights. Changing finished height means recalculating base carcase height and kick details, then regenerating the cut list.
When do shops use 21 in base depth?
Hallways, tight galley kitchens, and some vanity-adjacent runs. Shallower bases change every gable and bottom on the nest and may affect appliance choice. Treat as a deliberate exception.
Do frameless cabinets use the same outside standards?
Yes for room fit. Interior clear openings differ because there is no face frame. Overall depth and height targets remain aligned with counters and appliances.
