Standard Kitchen Cabinet Sizes Chart and Kitchen Dimensions Guide

Here are the standard kitchen cabinet sizes, straight from the spec books of the lines we sell: base cabinets are 34½ inches tall (36 with the countertop) and 24 inches deep; wall cabinets are 12 inches deep and 30, 36 or 42 inches tall, hung 18 inches above the counter; tall pantry cabinets are 84, 90 or 96 inches tall and 12 or 24 inches deep. Widths on all three step up in 3-inch increments, from 9 inches to 36 on uppers and to 42 or 48 on bases. Keep 42 inches of aisle in a working kitchen and you're most of the way to a layout that functions.

Those standard cabinet sizes prevent most of the expensive mistakes we see. We sell cabinets for a living and build kitchens too, so this guide works from the manufacturers' own books rather than a generic chart: one master size table, a line-by-line table showing where the four books we checked (Fabuwood Allure, KCD, J&K and US Cabinet Depot) actually differ, then the room-level numbers that decide whether those boxes make a kitchen that works. If you're still choosing between an L, U, galley or single-wall plan, start with our kitchen layouts guide and come back here to dimension it.

Key Takeaways

• Base: 34½" high, 24" deep, 9"–42" wide in 3" steps (Fabuwood Allure adds a 48"). The toe kick is 4½" high, and the counter lands at 36".
• Wall: 12" deep; 30", 36" or 42" tall; 12"–24" short boxes for over the range and fridge; 9"–36" wide in every line, wider in some.
• Tall: 84", 90" or 96" high; 24" deep in most lines, 12" for shallow pantries, 27" in J&K; 18"–30" wide (15"–36" in Allure).
• Not every line builds every size. Fabuwood's 39"-high walls and 93" towers are sold only in Galaxy Frost, Dove, Indigo and Timber; J&K and USCD skip the 39" base.
• Doors: on full-overlay lines a single door is about ½" narrower than its box; boxes up to 21" wide take one door, boxes from 24" take a pair.
• Room numbers: 18" from counter to uppers (54" off the floor), 42" work aisle for one cook, 48" for two, 36" for a walkway.

Standard Kitchen Cabinet Sizes Chart at a Glance

This is the master chart. Every number in it appears in at least three of the four spec books we checked, which is what "standard" should mean: a size you can order from almost any framed line without a modification charge.

The three families share one width grid so door lines can stack from floor to ceiling: a 30-inch upper sits over a 30-inch base, and a 24-inch pantry lines up with a 24-inch drawer base beside it. Why the grid steps in threes, and how to add boxes up to a wall length, is its own topic; our guide to cabinet sizes in 3-inch increments works two real walls through with fillers. For most other cabinet types there's a dedicated sizing guide, linked in the sections below, so this page stays the one-screen reference.

Sizes Line by Line: Where the Spec Books Differ

Charts online stop at the table above. The buying problems start at the edges, where one line builds a size and the next doesn't. These are the ranges in the current spec books, which you can open yourself in our spec book library:

Two of those edge cases trip up real orders. First, the 39-inch-high upper and 93-inch tower are not standard. Fabuwood builds them as complete cabinets in four Galaxy finishes only; the other Galaxy colors don't offer them (Desert Oak and Natural Oak list the 39-inch walls as box-only, with no door), so a plan drawn around a W3039 has to switch to 36- or 42-inch uppers if you change finish. Second, J&K talls are 27 inches deep, three inches proud of a 24-inch base run, so plan that step (or a matching panel) on the drawing before you mix lines. The Fabuwood-specific numbers, SKU by SKU, are in our Fabuwood cabinet sizes and specs guide.

Standard Base Cabinet Dimensions: Height, Depth and Width

Base cabinets sit on the floor, carry the countertop and set the kitchen's working height. Every book we checked lists the same box:

One number worth memorizing is 36 inches of finished counter height (our countertop heights and depths guide covers the exceptions). Nearly everything else in the kitchen, from appliance heights to stool heights, is designed around it.

Toe kick height and the finished depth

The toe kick is the recessed strip at the bottom of every base and tall cabinet, and it's the same 4½ inches high in all four books we checked; it's part of the 34½-inch box height, not added to it. On Fabuwood Allure it's a ¾-by-4½-inch plywood board attached to the cabinet, covered on site with a ¼-inch toe-kick skin in the cabinet's finish that's ordered separately (Fabuwood sells it in 8-foot lengths). Islands and runs that end in a panel need that cover on every exposed side, so count the linear feet when you order.

Depth works the same way: the 24 inches in every chart is the box to the face frame. Add the door (about ¾ inch on a full-overlay line) and the countertop's overhang, and the finished front edge of a standard counter sits around 25 to 25½ inches from the wall; our countertop depth guide gives the exact figures by material.

Width is where base cabinets differ most, because each type is sized to what goes in it or next to it. Door bases fill whatever width is left in the run. Drawer bases run 12 to 36 inches. Sink bases are sized to the bowl: 30 to 36 inches covers most sinks, and the full range, farmhouse bases and plumbing cutouts are in sink base cabinet sizes and types. Corners use a 33- or 36-inch lazy Susan (Allure LSB33 and LSB36) or a blind base that covers 36 to 51 inches of wall; see lazy Susan cabinet sizes and blind corner cabinet sizes. Allure's trash pull-outs mount in a 15-, 18- or 21-inch base (trash pull-out sizes). The appliance openings (24 inches for a dishwasher, 30 for a standard range) stay empty; don't fill them with cabinet. Every type is compared in our guide to the types of base cabinets, and you can see how widths combine in our base cabinet collection.

Wall Cabinet Dimensions: Height, Depth and Spacing

Wall cabinets (uppers) hang above the counters, and their key dimension isn't the cabinet at all; it's where it hangs:

The 18-inch gap between countertop and upper cabinets is the industry default, not a code requirement. It clears a coffee maker or stand mixer and keeps the bottom shelf within reach; the NKBA's countertop guideline only counts frontage that has at least 15 inches of clear space above it, so don't go lower than that over a work counter. Over the range the number is set by the hood or microwave manual instead. Layout lines, ledgers and hanging height are covered step by step in how to hang upper kitchen cabinets.

Which height you choose is mostly a ceiling question. Hung at 54 inches, a 30-inch upper tops out at 84, a 36-inch at 90 and a 42-inch at 96, the same three heights as the tall cabinets, so pantry and wall tops line up. Under an 8-foot ceiling that means 30-inch uppers leave a foot for a soffit or display, 36-inch uppers leave room for crown, and 42-inch uppers reach the ceiling; in a 9-foot room the 42s leave a foot to close with crown or a stacked cabinet. Taller uppers cost more but add shelf space, usually the cheapest storage upgrade in the kitchen. Every height, glass fronts and lift-up doors are covered in our wall and tall cabinet sizes guide; the deep box over the fridge gets its own page in over-refrigerator cabinet sizes, and closing the gap above the uppers is in kitchen cabinets to the ceiling.

Tall Cabinet Dimensions

Tall cabinets (pantries, utility and oven cabinets) run floor to nearly ceiling:

Oven and microwave towers follow the same heights but are sized to the appliance cutout; see wall oven cabinet dimensions.

The planning catch with talls: an 84-inch pantry lines up with 30-inch uppers, while a 96-inch pantry under an 8-foot ceiling leaves no room for crown or an uneven ceiling. Measure the true ceiling height at the cabinet's spot, and check that the box can be stood up: a 96-by-24-inch cabinet needs about 99 inches of diagonal to tilt upright. Shelf counts, roll-outs and pantry prices are in our pantry cabinet sizes and costs guide, and configurations are in our tall cabinet collection.

Cabinet Door and Drawer Front Sizes

There's no standard cabinet door size the way there's a standard box size, because the door is sized from the box. On the full-overlay framed lines we sell, the rule is simple: a single door is about half an inch narrower than its cabinet, and a pair splits the width with a small gap between. Here's what KCD prints for its full-overlay Premier doors, which matches Fabuwood Allure's 8½- to 20½-inch doors on 9- to 21-inch cabinets:

Three practical takeaways. Wall doors run about 1¼ inches shorter than the box, so a 30-inch upper carries a 28¾-inch door. Single doors stop at 21-inch cabinets; from 24 inches up, both bases and uppers switch to a pair, which keeps a door from swinging far into the aisle. And partial-overlay or "builder" doors are smaller (KCD's Builder door on a B12 is 10 by 20.7 inches), which is why you can't swap doors between lines and expect them to fit. Drawer boxes inside are shallower than the front suggests: Allure's top drawer has a 3-inch interior height. Drawer stacks and deep pot drawers are compared in our drawer base cabinet sizes guide.

Walkway & Clearance Recommendations

Cabinet sizes tell you what fits against the walls; clearances tell you whether the kitchen works as a room. These are the planning numbers designers use, from the National Kitchen & Bath Association's Kitchen Planning Guidelines with Access Standards:

The clearance that kills the most island plans is simple addition. A 24-inch counter, a 42-inch aisle, a 36-inch-deep island, another 42-inch aisle and another 24-inch counter come to 168 inches: about 14 feet of room width with cabinets on both walls. With cabinets on one wall only (24 + 42 + 36 + a 36-inch walkway, plus overhangs) the working rule is about 13 feet. In a tighter room, a slim island, a peninsula or a cart beats squeezing aisles to hallway width; our kitchen island clearance guide runs the numbers for seating, and kitchen island cabinet sizes covers the boxes that build one.

Landing space beside each work center

The NKBA guidelines also set how much countertop each appliance needs beside it, and these numbers decide where tall cabinets can go:

• Sink: at least 24 inches of counter on one side and 18 inches on the other.
• Cooktop or range: at least 12 inches on one side and 15 inches on the other. On an island, the counter should also run at least 9 inches behind the cooktop.
• Refrigerator: 15 inches on the handle side, or 15 inches directly across within 48 inches.
• Above the cooking surface: 24 inches to a protected, noncombustible surface such as a range hood. The residential code the NKBA cites asks for 30 inches to unprotected combustible material, which is why the upper over a range is a short 12- to 18-inch box.
• Total work counter: 158 inches of 24-inch-deep countertop frontage, with at least 15 inches of clear space above, covers landing, prep and storage in a typical kitchen.

Planning for a wheelchair user or aging in place changes several of these (lower work counters, knee spaces at the sink and cooktop, 60 inches between the arms of a U). Those numbers are collected in our guide to ADA kitchen cabinet heights and clearances.

The Kitchen Work Triangle

The work triangle is the path between the three main work centers: the cooking surface, the cleanup sink and the refrigerator. It is the oldest planning rule in kitchen design, and the NKBA still publishes it as a guideline:

Under 4 feet, two cooks collide and there's no landing space; over 9 feet, every pot of pasta becomes a walk. The cabinet consequence is the "tall obstacle" line: a pantry or oven tower between the sink and the range breaks the triangle, which is why tall cabinets belong at the ends of runs. Island and two-cook kitchens are often planned as work zones instead, so treat the triangle as a sanity check; our kitchen layouts guide shows it in L, U, galley and island plans.

Standard Kitchen Size and Typical Room Dimensions

There is no single standard kitchen size, but there are useful reference points. An NKBA study of newly built single-family homes (reported in October 2016) put the average kitchen at 161 square feet, just under 13 × 13 feet, ranging from 103 square feet in homes under 1,500 square feet to 238 in homes of 4,000 square feet or more. The NKBA's storage guideline sorts kitchens the same way: small under 150 square feet, medium 151 to 350, large above 350.

The dimension that matters more than square footage is the width between opposite walls, because the cabinets and aisles have to fit across it. Using 24-inch-deep base cabinets and the aisle widths above:

How much cabinetry those rooms need is set by the NKBA's storage guideline for total shelf and drawer frontage: 1,400 inches for a small kitchen, 1,700 for a medium one and 2,000 for a large one, counting wall, base, drawer and pantry storage together. Cabinet pricing uses a different reference, the 10 × 10 kitchen, which is a quoting benchmark rather than an average room; see what a 10x10 kitchen cabinet price means.

Common Measurement Mistakes

These are the errors we catch most often on homeowner drawings:

• Measuring each wall once. Walls are rarely square. Measure at the floor, at 36 inches and at upper-cabinet height, and plan to the smallest number.
• Measuring the old appliance, not the new one. A 30-inch range needs a true 30-inch opening; a refrigerator needs its width plus the air gap in its installation manual.
• Ignoring window casings and outlets. Cabinet runs stop at the casing, not the glass. Note sill, switch and vent heights too.
• Measuring to the drywall, not the obstruction. Radiators, bulkheads, plumbing and baseboard heat all steal space a wall-to-wall number hides.
• Assuming the ceiling is level. Check height at every corner of the run; the difference decides crown and tall-cabinet choices.
• Leaving no filler allowance. Boxes in 3-inch steps almost never total your wall exactly; plan filler at walls and corners so doors and drawers clear. Our guide to end panels, scribe molding and fillers shows how the gaps get closed.

The full step-by-step, with a printable checklist, is in how to measure a kitchen for cabinets. You don't have to get it perfect: a sketch with wall lengths, window and door positions and appliance sizes is enough for a designer to start, and final dimensions are verified before anything is ordered.

Frequently Asked Questions

What size are standard kitchen cabinets?

Base cabinets are 34½ inches tall (36 with the counter) and 24 inches deep. Wall cabinets are 12 inches deep and 30, 36 or 42 inches tall. Tall cabinets are 84, 90 or 96 inches high and usually 24 inches deep. Widths for all three step up in 3-inch increments: 9 to 42 inches on bases and 9 to 36 on uppers in every line we checked.

How deep are kitchen cabinets?

Base cabinets are 24 inches deep to the face frame; the door and countertop overhang bring the front edge out about another inch or more. Wall cabinets are 12 inches deep, apart from the 24-inch-deep box over a refrigerator (27 inches in J&K). Tall pantries are 24 inches deep in most lines, with 12-inch shallow pantries in Fabuwood Allure and 27-inch pantries in J&K.

How tall are kitchen cabinets?

Base cabinets are 34½ inches tall, including the 4½-inch toe kick, and a 1½-inch countertop brings them to 36. Wall cabinets come 30, 36 or 42 inches tall. Fabuwood also builds a 39-inch upper, but only in Galaxy Frost, Dove, Indigo and Timber. Tall cabinets run 84, 90 or 96 inches, the same heights the tops of hung uppers reach, so the two line up.

How wide is a standard kitchen cabinet?

There's no single width; cabinets are built on a 3-inch grid. Base cabinets run 9 to 42 inches (Allure adds a 48), wall cabinets 9 to 36 in every line (Allure continues to 39, J&K to 42, KCD to 45), and pantries 18 to 30 (Allure 15 to 36). The widths that turn up on most orders are 15, 18, 24, 30 and 36 inches.

How wide can a single cabinet door be?

On the framed lines we sell, about 21 inches of cabinet width is the limit for one door. In the Fabuwood Allure spec book, the doors on 9- to 21-inch single-door cabinets measure 8½ to 20½ inches wide. From 24 inches up, both base and wall boxes switch to a pair of doors, each roughly half the width, which keeps the door from swinging far into the aisle.

What is the standard cabinet door size?

It depends on the cabinet. On full-overlay framed lines, a single base door is about half an inch narrower than its box and about 21½ inches tall under a drawer front, and a wall door is about 1¼ inches shorter than its box: 28¾ inches on a 30-inch upper, 34¾ on a 36-inch. Cabinets 24 inches and wider take two doors.

How much space do you need for a dishwasher?

Leave an opening 24 inches wide, 24 inches deep and 34½ inches high to the underside of the countertop, the same height as the base cabinets beside it, and confirm against your model's installation guide. If the dishwasher ends a run, order a finished dishwasher return panel to close the exposed side: Fabuwood's DWR is 34½ inches tall and 24 inches deep, in 1½-, 3- or 6-inch thicknesses.

How high should wall cabinets be above the counter?

18 inches is the standard height between countertop and upper cabinets, putting the bottom of the uppers 54 inches off the floor; don't go below 15 inches over a work counter. Over a range, allow 24 to 30 inches of clearance depending on the hood or over-the-range microwave's installation manual.

How wide should kitchen walkways be?

36 inches for pure walkways, 42 inches for a one-cook work aisle and 48 inches where two cooks work at once. Every side of an island that faces a work zone should get 42 to 48 inches.

What is the standard size of a kitchen?

There isn't a fixed standard, but the NKBA's study of new single-family homes found an average of 161 square feet, just under 13 × 13 feet. Kitchens in homes under 1,500 square feet averaged 103 square feet, and those in homes of 4,000 square feet or more averaged 238.

What is the kitchen work triangle?

The path between the range, the sink and the refrigerator. NKBA guidelines recommend each leg be 4 to 9 feet long, with the three legs totaling no more than 26 feet, no tall cabinet between two of the points and no traffic route through the middle.

Do 9-foot ceilings need custom cabinets?

No. The standard answer is 42-inch uppers with crown molding, or stacked cabinets for a to-the-ceiling look. Standard tall cabinets (84 to 96 inches) also work; the extra ceiling height becomes crown or open space.

How accurate do my measurements need to be for a quote?

Within about half an inch is plenty to start. Design quotes are built from your rough measurements, and final dimensions are verified before ordering, by your installer or through our free design review, so small errors get caught before they cost anything.
