Standard kitchen cabinet sizes come down to a short list. A base cabinet is 34 1/2 inches high and 24 inches deep, a wall cabinet is 12 inches deep, and a tall cabinet runs 84 to 96 inches high. Widths step up in 3-inch increments. Those numbers hold across manufacturers, retailers and dealers, though the edges of the charts do not agree, and this guide shows where.
The part nobody prints is what the grid does to your wall. A 3-inch grid seldom fits a real wall exactly, so the leftover inches become fillers or custom widths, and that is where the budget moves. If you want the style side of cabinets first, our smart kitchen design tips are a good place to start.
Standard kitchen cabinet sizes at a glance
The table below gives the consensus numbers for kitchen cabinet dimensions, drawn from KraftMaid, a cabinet manufacturer, Lily Ann Cabinets, a retailer, and a Cabinet Corp guide. All three sell cabinets, so treat them as trade norms, not building code. The base row matters most, because every other cabinet height hangs from it.
Common dimensions at a glance
| Cabinet | Height | Depth | Width |
|---|---|---|---|
| Base | 34 1/2 in., 36 in. with a 1 1/2 in. countertop | 24 in. box, 25 to 26 in. with doors and countertop | 3 in. steps, roughly 9 to 48 in. |
| Wall | 30, 36 or 42 in. standard; 12 to 24 in. short units | 12 in. | 3 in. steps, roughly 9 to 36 in. |
| Wall over a refrigerator | Short units, 12 to 24 in. | 24 in. | Varies by line |
| Tall pantry or utility | 84, 90 or 96 in. | 24 in. (12 in. also offered) | Roughly 18 to 36 in. |
Wall cabinets usually hang with their bottom edge 54 inches from the floor, which leaves 18 inches above a 36-inch counter. NKBA’s Kitchen Planning Guidelines ask for at least 15 inches of clearance above the counter, so the 18-inch norm clears it by 3 inches, a margin that leaves room for under-cabinet lighting. Our look at kitchen cabinet trends covers the door styles that sit on these boxes.
Kitchen cabinet depth from box to countertop
A base cabinet’s 24-inch depth describes the box only. KraftMaid says its measurement does not include doors and drawers, and Lily Ann puts the finished depth with a countertop at 25 to 26 inches. So the finished face of a run sits 1 to 2 inches proud of the box, which matters when you plan aisle widths from the cabinet face.
Why base cabinets are usually 24 inches deep
Why 24 inches and not more? KraftMaid says anything deeper makes it hard to reach items stored inside. It offers 12-inch shallow bases for pantry walls and 27-inch deep bases for larger cooktops and sinks. Lily Ann lists shallow bases at 12, 15 and 18 inches, and notes that a deeper cabinet can be cut down to the depth you need.
How cabinet depth affects aisle clearance
Depth changes your aisles by the inch. A 27-inch base steals 3 inches from the work aisle, which NKBA sets at 42 inches for one cook and 48 inches for more than one. Our guide to maximizing kitchen space and the list of layout mistakes designers avoid both start with tight aisles.
Disagreements between published size charts
Search a size chart and you will find the same numbers repeated, with small gaps. This table puts four published sources side by side, so you can see the spread at a glance. The Home Depot figures come from its buying guide.
Published size charts compared
| Item | KraftMaid | Lily Ann | Cabinet Corp | Home Depot |
|---|---|---|---|---|
| Base depth | 24 in. (12 and 27 also) | 24 in. (12, 15, 18 also) | 21 or 24 in. | 24 to 30 in. |
| Narrowest base | 6 in. | 12 in. | 9 in. | Not listed |
| Widest base | 48 in. | 42 in. | 48 in. | Not listed |
| Wall depth | 12 in. (24 over a fridge) | 12 in. (24 over a fridge) | 12 in. standard, up to 24 | 12 to 18 in. |
| Tall height | 84 to 96 in. | 84, 90, 96 in. | 84, 90, 96 in. | 84 to 94 in. |
Why published charts differ
Some of the gaps may trace to product lines. Lily Ann says its sizes come from its own listings and that other lines can offer fewer sizes. Even one chart disagrees with itself. Cabinet Corp’s table lists tall cabinets 18 to 33 inches wide, while its text says 12, 24 and 36 inches.
So read a size chart as a range, not a rule, and note that depth and width limits vary most. The only chart that governs your kitchen is the size sheet for the line you buy. Hayden Island Cabinets, the studio’s cabinet supplier, publishes a dimensions guide with no measurements in it, so ask for the size sheet of the line you choose before you draw the plan.
Wall and tall cabinets by ceiling height
Wall cabinets have no single standard height. KraftMaid offers 12 to 54 inches, and the right one depends on your ceiling height. The arithmetic is simple. Subtract the 54-inch hanging height from the ceiling, and the remainder is the space you must fill. The table below is this guide’s own sum from KraftMaid’s and Lily Ann’s numbers.
Wall cabinet height by ceiling height
| Ceiling | Space above 54 in. | Ways to fill it |
|---|---|---|
| 8 ft (96 in.) | 42 in. | A 42 in. wall cabinet reaches the ceiling, and a 36 in. one leaves 6 in. for crown molding |
| 9 ft (108 in.) | 54 in. | A 54 in. wall cabinet, or a 42 in. cabinet with a 12 in. unit stacked above |
| 10 ft (120 in.) | 66 in. | A 42 in. cabinet plus a 24 in. stacked unit, or taller uppers by special order |
Options for filling the space above cabinets
KraftMaid says a 42-inch wall cabinet fills the space to an 8-foot ceiling, while 36- and 39-inch units leave room for crown molding and accent lighting. Our guide to layered kitchen lighting explains why that gap can be worth keeping. For the tall cabinets, an 84-inch unit fills an 8-foot room with a 12-inch soffit, and a 90-inch pantry lines up with the top of a 36-inch wall cabinet hung at 54 inches.
Lily Ann notes the same alignment, since a 30-, 36- or 42-inch wall cabinet tops out at 84, 90 or 96 inches. Matching these top lines is cheap on paper and hard to fix once the cabinets arrive. Our guide to built-in shelving ideas shows how a tall run can double as a display wall.
Widths, fillers and the leftover inches
How fillers handle leftover inches
Here is the trap in the 3-inch grid. KraftMaid’s widths run 6 to 48 inches in 3-inch steps, and Lily Ann’s run 12 to 42. In both charts every width is a multiple of 3, so any run of those cabinets adds up to a multiple of 3. Your wall rarely does, so the leftover is always 0, 1 or 2 inches. Captivating Cabinets, a dealer, says installers close the remainder with filler strips, usually 1 to 3 inches per run.
| Wall run | Nearest stock total | Filler left |
|---|---|---|
| 96 in. | 96 in. (for example 36 + 30 + 30) | 0 in. |
| 100 in. | 99 in. | 1 in. |
| 104 in. | 102 in. | 2 in. |
Corner cabinets and the space they use
Corners add their own wall math. Lily Ann says a 36-inch blind corner base uses 39 inches of wall and a 42-inch one uses 45, while a lazy susan base takes 33 or 36 inches on each wall. A tight room feels these numbers first, and our piece on the micro kitchen shows how small plans spend every inch.
When to consider a modified cabinet width
A one-inch filler at a wall is invisible. A two-inch filler beside a range or a tall cabinet can read as a mistake, and fillers at both ends of a run can read worse. That is the moment to ask whether a modified width would be cleaner. KraftMaid’s special-order program modifies width, depth and height to 1/16 inch, and Captivating describes width reductions in 1-inch or 1/4-inch steps as a semi-custom option.
Storage that the sizes add up to
NKBA turns cabinet sizes into a storage target, and it gives each cabinet type its own share. For a medium kitchen of 151 to 350 square feet, it recommends 1,700 inches of total shelf and drawer frontage. The split is 360 in the wall cabinets, 615 in the base cabinets, 400 in the drawers, 230 in the pantry and 95 in a miscellaneous bucket. It also says the figure for each cabinet is the width in inches times the number of shelves and drawers times the depth in feet.
Examples using the NKBA storage formula
The sums below are this guide’s own, using NKBA’s formula and our assumptions about how many shelves and drawers each unit holds.
| Unit | Formula | Frontage |
|---|---|---|
| 36 in. wide, 24 in. deep base with three drawers | 36 x 3 x 2 | 216 in. |
| 30 in. wide, 12 in. deep wall cabinet with two shelves | 30 x 2 x 1 | 60 in. |
| 24 in. wide, 24 in. deep pantry with five shelves | 24 x 5 x 2 | 240 in. |
What these cabinet examples add up to
Two of those three-drawer bases reach 432 inches, above the 400-inch drawer target, which shows how much storage a drawer base carries. One tall pantry covers the 230-inch pantry target. You would need six wall cabinets of the size shown to hit 360 inches, and a 24-inch-deep unit over the refrigerator counts double, since depth is in the formula. NKBA also asks for at least 400 to 560 inches of the total within 72 inches of the sink. For ideas on where the pantry goes, see our pantry design ideas and the guide to walk-in pantries.
Custom sizing and the cases that justify the cost
Custom sizing earns its cost where standard sizes leave a visible gap. We found no published price for a size change in these sources, and no independent county-level cabinet data for Marin, Sonoma or Napa, so this guide gives no dollar figures. What the sources do say is useful. Captivating warns that every modification carries a charge, and that in quotes its team has seen, modification charges reached a third of the total. NKBA’s cost note, dated 2012, adds that several small cabinets cost significantly more than fewer, larger ones in the same space.
When custom sizing may be worth the cost
Three situations usually justify the change. First, a wall-ending run with a 1- or 2-inch gap you cannot hide. Second, a tall ceiling of 9 or 10 feet, where taller uppers beat stacking. Third, a shallow depth for a pantry wall or a narrow hallway. The better spend is on those before a custom door profile, though that is a judgment call, so run it past your designer.
Where standard sizing is usually enough
Skip extra depth on base cabinets. KraftMaid’s reasoning is reach, and a 27-inch base also costs you 3 inches of aisle. If a tall cook needs a higher counter, Cabinet Corp says you can raise a base cabinet’s height with a countertop underlay or a thicker countertop, no custom box needed.
Hayden Island’s own kitchen cabinets page says standard base, wall and tall sizes give structural consistency, while custom sizing improves fit and proportion. The studio is an authorized Hayden Island Cabinets dealer, so ask for that line’s size sheet at your first design meeting. Our guide to planning a modern kitchen remodel without overspending and tips to help you save when remodeling cover how to weigh these trade-offs. The benefits of working with a kitchen and bath designer include catching a bad filler on paper, and our countertop materials guide covers the surface that sits on top.
FAQ
Toe kick height
Lily Ann says a base cabinet’s toe kick is usually about 4 1/2 inches high, and its trim pieces measure 4 1/2 inches. Ask your supplier for the recess depth of your cabinet line, since this guide did not find a standard for it.
Taller counter for tall cooks
NKBA’s Access Standard recommends at least two work-counter heights in a kitchen, one from 28 to 36 inches and one from 36 to 45 inches. A 36-inch counter is the norm, and a raised section is a design choice. Raise it on a prep zone or an island, and talk it through at your first design meeting.
Permit for replacing cabinets
Permit Sonoma lists cabinets and counter tops as exempt finish work in unincorporated Sonoma County, but not plumbing rearrangement. Marin County lists an online minor improvement permit for non-structural kitchen remodels not over 400 square feet. See its permit page and Permit Sonoma. Rules vary by city, so confirm with your building department. This guide makes no Napa claim.
