Standard Kitchen Cabinet Dimensions & Clearances Cheat Sheet
Cabinet boxes are built to a small set of trade-standard dimensions. Knowing them lets you lay out a kitchen on the back of a cut list, confirm that a door overlay will clear a drawer front, and order the right box without waiting on a design revision. This guide collects the base, wall, and tall cabinet sizes — plus toe-kick and countertop overhang rules — in one place.
Standard base cabinet dimensions
The base cabinet is the anchor of every kitchen layout. The carcass height is 34-1/2"(876 mm), which becomes a 36" finished counter height (914 mm) once a 1-1/2" countertop is added on top. Depth is 24" (610 mm) for a standard full-depth base, with the countertop overhanging slightly at the front.
Base cabinets sit on a recessed toe kick rather than directly on the floor. The toe kick space is 4" high (102 mm) with a 2-1/2" to 3" recess (64–76 mm) from the face of the doors and drawer fronts.
Counter height = Carcass height (34-1/2") + Countertop thickness (1-1/2") = 36"
Standard wall (upper) cabinet dimensions
Wall cabinets are measured by depth and height far more than by width. The standard depths are 12" (305 mm) for everyday dishes and glassware, 13" (330 mm) as a common step-up, and 14" (356 mm) when you need to clear larger plates or a microwave shelf. The three standard heights are 30", 36", and 42"(762, 914, and 1067 mm) — the 42" box reaching all the way to a standard 96" (2438 mm) ceiling is the most common modern choice.
Leave an 18" (457 mm) clearance between the countertop and the bottom of the wall cabinets. That sets the bottom of the uppers at 54" (1372 mm) above the floor — high enough for a backsplash and a countertop appliance, low enough to reach.
Tall and pantry cabinets
Tall cabinets — pantry, oven, and utility towers — share the 24" (610 mm) depth of a base cabinet but run full height. Standard heights are 84",90", and 96" (2134, 2286, and 2438 mm). Widths range from a 12" (305 mm) pull-out spice tower up to 24"–36" (610–914 mm) pantry doors. Because they carry the full load of the room's vertical layout, measure the finished floor-to-ceiling height and subtract for crown and any flooring that has yet to go in.
Toe-kick dimensions
The toe kick is where finish carpentry and ergonomics meet. A 4" high toe kick with a 2-1/2"–3" recess lets you stand close enough to the counter to work without kicking the cabinet face. Toe kicks are usually built as a separate base frame set back from the carcass, then trimmed with a finished toe-kick skin or base molding.
Countertop overhang rules
The countertop should overhang the cabinet box to shed spills and protect the drawer fronts. Leave a 1-1/2" (38 mm) overhang at the front of the base cabinets, and 1/4" to 1/2" (6–13 mm) at exposed ends. A greater side overhang than that looks unsupported and invites chipping. Where a dishwasher or range interrupts the run, keep the counter continuous and support it on the adjacent cabinets.
Quick-reference table
| Element | Standard (imperial) | Metric | Notes |
|---|---|---|---|
| Base carcass height | 34-1/2" | 876 mm | Excludes countertop and toe kick / legs. |
| Finished counter height | 36" | 914 mm | 34-1/2" carcass + 1-1/2" counter. |
| Base depth | 24" | 610 mm | Full-depth base, counter overhangs at front. |
| Toe kick height / recess | 4" / 2-1/2"–3" | 102 mm / 64–76 mm | Recess measured from door face. |
| Upper depths | 12" / 13" / 14" | 305 / 330 / 356 mm | Deeper boxes reduce headroom at the counter. |
| Upper heights | 30" / 36" / 42" | 762 / 914 / 1067 mm | 42" reaches a 96" ceiling. |
| Counter-to-upper clearance | 18" | 457 mm | Bottom of uppers at 54" AFF. |
| Counter front overhang | 1-1/2" | 38 mm | Protects drawer fronts. |
| Counter end overhang | 1/4"–1/2" | 6–13 mm | Exposed ends only. |
Trap for the new builder: these are nominal standards. Farmhouse sinks, ADA-height counters, and custom islands all change the numbers — always build to the actual specification, not the catalog average.
Putting it to work
Once the boxes are set, the measurement work moves to the fronts. Use the cabinet door size calculator to turn each finished opening into an exact overlay and cut size, and the drawer slide calculator to size drawer boxes for undermount and side-mount slides.
