Standard Kitchen Cabinet Sizes Chart: Width, Height & Depth

Standard kitchen cabinet sizes vary by cabinet type, but most U.S. kitchen layouts use base cabinets that are 34.5 inches high and 24 inches deep, wall cabinets that are typically 12 inches deep, and tall pantry cabinets commonly available in 84-, 90-, and 96-inch heights.

Cabinet widths are more flexible. Standard base and wall cabinets are often sold in 3-inch width increments, while sink bases, corner cabinets, appliance cabinets, and other specialty units follow their own sizing options.

Use the chart below to compare common kitchen cabinet dimensions before planning your layout. These are general sizing references, not guaranteed dimensions for every RARA cabinet collection.

Standard Kitchen Cabinet Sizes at a Glance

Cabinet Type	Common Widths	Standard Height	Common Depth
Base Cabinets	Often 9″–36″, depending on style	34.5″ cabinet box	24″
Wall Cabinets	Often 9″–36″	30″, 36″, 42″	12″
Tall Pantry Cabinets	Commonly 12″–36″	84″, 90″, 96″	12″ or 24″
Sink Base Cabinets	Commonly 24″–36″ or wider	34.5″	24″
Above-Refrigerator Cabinets	Varies by refrigerator and collection	Varies	Often deeper than standard wall cabinets
Corner Base Cabinets	Varies by corner configuration	Commonly 34.5″	Depends on cabinet design

Important: Cabinet dimensions refer to the specified cabinet unit, not necessarily the complete installed kitchen. Countertop thickness, overhangs, decorative panels, fillers, hardware, and appliance clearances can affect the finished measurements. Always verify the selected cabinet SKU before ordering.

How Tall Are Kitchen Cabinets with Countertops?

A typical kitchen base cabinet is 34.5 inches high before the countertop. When paired with a 1.5-inch-thick countertop, the finished height is approximately 36 inches.

However, countertop thickness varies by material and installation, so the final height should be calculated using your actual countertop specification.

What Widths Do Standard Kitchen Cabinets Come In?

Many stock kitchen base and wall cabinets are available in 3-inch width increments, with widths such as 9, 12, 15, 18, 21, 24, 27, 30, 33, and 36 inches.

This does not mean every cabinet type or collection offers every width. Drawer bases, sink bases, corner cabinets, pantry units, and appliance cabinets often have different size selections.

Why Standard Sizes Matter

Most stock, RTA, and semi-custom kitchen cabinets are designed around common dimensional standards so they can work with standard countertops, sinks, dishwashers, ranges, refrigerators, and typical kitchen layouts.

These dimensions are useful as a planning baseline, but they are not universal. Exact cabinet widths, depths, toe-kick dimensions, and specialty sizes vary by manufacturer and product line, so always confirm the specifications of the exact cabinet you plan to order.

Use this guide as a planning reference, then compare the dimensions with your room measurements, appliance specifications, countertop thickness, and the exact cabinet collection you are considering.

Whether you choose pre-assembled cabinets or RTA cabinets, the cabinet dimensions should be verified before ordering because specialty cabinets, appliance cabinets, fillers, panels, and trim can change the final layout.

Kitchen Cabinet Dimensions by Cabinet Type

Here’s a detailed breakdown of common U.S. kitchen cabinet dimensions, including base cabinets, wall cabinets, tall pantry units, and specialty cabinets. Use these measurements as a starting point, then check the specifications of each cabinet you plan to order.

Base Cabinets (Floor Cabinets)

Feature	Common Planning Dimension	Notes
Cabinet Box Height	34.5″	Typical height before countertop
Finished Counter Height	About 36″	Common when paired with a 1.5″ countertop
Standard Depth	24″	Common depth for standard base cabinets
Reduced-Depth Options	Varies by manufacturer	Some cabinet lines offer shallower base cabinets for specialty layouts
Common Widths	Often available in 3″ increments	Exact width range varies by manufacturer and cabinet type
Toe Kick	Check manufacturer specifications	Toe-kick height and recess vary by cabinet system

RARA reference: Most RARA base cabinets are 34.5″ high and 24″ deep. Always check the individual product page for the exact width and specialty-cabinet dimensions before ordering.

Standard base cabinet dimensions do not show how the interior storage is divided. For stacked drawer options, compare common widths, drawer counts, and storage uses in our drawer base cabinet buying guide.

For cabinet-base design alternatives, compare recessed toe kicks with baseboard and no-toe-kick cabinet options before finalizing the installation.

Planning tip: Do not choose cabinet depth and island size without checking the finished aisle space. Work-aisle requirements depend on the layout and number of cooks, so measure from the finished cabinet or countertop edges—not only from the wall.

When base cabinets are used away from the perimeter, the finished layout must also account for panels, countertop overhangs, seating, and surrounding aisles. See our kitchen island cabinet guide for island-specific sizing and layout considerations.

Wall / Upper Cabinets

Ethereal White Micro Shaker Wall Cabinet with 2 Doors W3012

Ethereal White Micro Shaker Wall Cabinet with 2 Doors (Pre-Assembled) 30″W x 12″H x 12″D

Style: Framed Cabinet. Slim shaker / recessed panel door style in a white finish.
Material: Premium solid wood door frame with HDF center panel, plywood cabinet construction.
Assembly: Pre-Assembled. Ships fully assembled and ready for installation.
Suitable for: Storing dishes, glassware, mugs, pantry items, and everyday kitchen essentials. A versatile wall storage solution that helps maximize vertical space.

SKU: ASD-EWM-W3012

Wall cabinets are mounted above base cabinets and countertops to provide accessible storage without using floor space. They are commonly used for dishes, glassware, pantry items, spices, and other everyday kitchen essentials.

Feature	Common Planning Dimension	Notes
Standard Heights	30″, 36″, 42″	Other specialty heights may be available by collection
Standard Depth	12″	Common for general wall-cabinet storage
Deeper Wall Cabinets	15″ or specialty depths	Often used where additional storage or appliance clearance is needed
Above-Refrigerator Cabinets	Often deeper than standard wall cabinets	Depth should be coordinated with refrigerator depth and surrounding panels
Common Widths	Often available in 3″ increments	Exact width range varies by manufacturer and cabinet type
Countertop-to-Cabinet Clearance	About 18″ is common	Verify backsplash, appliance, range-hood, and local installation requirements

Planning tip: Do not choose wall-cabinet height based on ceiling height alone. First confirm the finished countertop height, the space required above the countertop, and whether the cabinet run needs to align with a refrigerator cabinet, range hood, microwave, window, or decorative molding.

How to Choose 30″, 36″, or 42″ Wall Cabinets

30″ wall cabinets can work well where ceiling height is limited or where more open wall space is desired above the cabinets.
36″ wall cabinets provide additional storage while still leaving room for molding or ceiling transitions in many layouts.
42″ wall cabinets are often used when the design calls for cabinets extending closer to the ceiling and more vertical storage.

Before choosing a wall-cabinet height, measure from the finished floor and countertop position rather than relying on ceiling height alone.

RARA reference: Standard RARA wall cabinets are commonly 12″ deep, while available heights, widths, and specialty depths vary by cabinet collection. Always check the exact product specifications before ordering.

Tall / Pantry / Utility Cabinets

Ethereal White Micro Shaker Base Cabinet with 2 Doors (RTA) 30″W x 34½″H x 24″D

Style: Framed Cabinet. Slim shaker / recessed panel door style in a white finish.

SKU: RTA-EWM-B30

Tags: RTA Cabinets, Shaker Style, Tiered shipping rates

Tall cabinets use vertical space for pantry storage, built-in appliances, and full-height kitchen organization. When choosing a tall cabinet, consider not only the cabinet height but also the ceiling, adjacent wall cabinets, refrigerator or appliance placement, fillers, and any crown molding or trim.

Feature	Common Planning Dimension	Notes
Common Heights	84″, 90″, 96″	Exact heights vary by cabinet collection
Standard Depth	24″	Common for pantry cabinets aligned with standard base cabinets
Shallow Depth	12″	Useful where less floor depth is available
Common Widths	Often 12″–36″	Exact widths depend on the cabinet type and manufacturer
Installation Clearance	Varies by room	Allow space for installation, fillers, trim, and uneven ceilings

What Are Standard Kitchen Pantry Cabinet Sizes?

Standard kitchen pantry cabinets are commonly 84, 90, or 96 inches tall. Widths often range from 12 to 36 inches, while 12-inch and 24-inch depths are common options.

The best pantry dimensions depend on your ceiling height, available floor space, nearby appliances, and the amount of storage you need.

For example, a 24-inch-deep pantry can align with standard base cabinets, while a shallower pantry may be useful in a narrow kitchen. An 84-inch-tall cabinet can leave room above for trim or decorative space, while taller cabinets can provide additional enclosed storage.

When selecting a pantry, check the full cabinet height, door swing, shelf arrangement, required installation clearance, and compatibility with neighboring cabinet units. Available dimensions vary by collection.

Planning tip: Do not select an 84″, 90″, or 96″ pantry cabinet based only on the ceiling height. Check the finished floor height, cabinet installation clearance, adjacent wall-cabinet height, crown molding, and whether the pantry needs to align with a refrigerator or built-in appliance cabinet.

How to Choose an 84″, 90″, or 96″ Tall Cabinet

84″ tall cabinets are commonly used where the design needs more clearance above the cabinet or where the pantry must align with shorter wall-cabinet runs.
90″ tall cabinets can provide additional vertical storage while still leaving some room for trim or ceiling transitions in many layouts.
96″ tall cabinets can extend closer to an 8-foot ceiling, but installation clearance and ceiling variation must be checked carefully before ordering.

The best height is the one that aligns with the rest of the cabinet run and can be installed safely in the actual room.

RARA reference: The pantry cabinet shown above is 18″W × 84″H × 24″D. Other tall-cabinet sizes vary by collection, so check the exact product specifications before finalizing the kitchen layout.

Once you have narrowed down the dimensions, compare shelf layouts, usable interior space, and assembly options in our kitchen pantry cabinet buying guide. These details help determine whether a cabinet that fits your layout will also meet your storage needs.

Are Bathroom Vanity Cabinet Sizes Different from Kitchen Cabinets?

Yes. Bathroom vanity cabinets often differ from kitchen base cabinets in depth, width, and interior configuration. Their dimensions depend on the sink type, plumbing requirements, and available bathroom space.

For bathroom-specific dimensions, see our Bathroom Vanity Size Guide.

Other / Specialty Cabinets

Specialty cabinets are designed for specific appliances, plumbing, corners, or storage needs. Unlike standard base, wall, and tall cabinets, their dimensions depend heavily on the cabinet type, appliance specifications, and the surrounding layout.

Cabinet Type	What to Verify Before Ordering	Why It Matters
Sink Base Cabinet	Sink width, bowl position, plumbing, and countertop cutout	Sink and plumbing requirements can limit usable cabinet space
Refrigerator Cabinet	Refrigerator width, height, depth, door swing, and required ventilation	Appliance dimensions vary significantly by model
Oven / Microwave Cabinet	Manufacturer cutout dimensions, electrical requirements, and ventilation	Built-in appliances require model-specific openings
Corner Cabinet	Corner dimensions, adjacent cabinet depth, door swing, and handle clearance	Small layout differences can affect access and door operation
Fillers & Finished Panels	Remaining wall gaps, appliance clearance, and exposed cabinet ends	Fillers and panels affect the final installed width of the cabinet run

If you are planning an apron-front sink, use our farmhouse sink cabinet size guide to compare sink sizes, minimum cabinet requirements, and cabinet compatibility before choosing the sink base.

Planning tip: Do not select a specialty cabinet from the cabinet dimensions alone. Check the installation manual for the exact sink or appliance first, then confirm the cabinet opening, fillers, finished panels, and surrounding clearances.

For storage above the refrigerator, see our over-the-fridge cabinet size guide to compare common cabinet widths, depths, and the clearances that need to be checked before ordering.

If you are comparing undercounter microwave installations, our microwave base cabinet guide explains cabinet widths, clear openings, usable depth, and model-specific installation requirements.

If you have not measured the room yet, use our guide on how to measure your kitchen for cabinets before creating the final cabinet list.

Using This Guide for Your Kitchen or Bath

Measure the finished space first. Record the wall-to-wall width, floor-to-ceiling height, window and door locations, and any areas where the walls or floor are not perfectly level.
Confirm appliances and sinks before finalizing cabinet sizes. Use the exact manufacturer specifications for the refrigerator, range, dishwasher, microwave, oven, and sink so the cabinet openings and surrounding clearances match the products you will actually install.
Plan tall cabinets as part of the full cabinet run. Do not choose an 84″, 90″, or 96″ cabinet from ceiling height alone. Check installation clearance, adjacent wall-cabinet height, refrigerator placement, fillers, crown molding, and any soffits.
Include fillers, panels, and trim in the total layout. The cabinet-box dimensions alone may not equal the final installed width of the cabinet run.
Verify cabinet dimensions before ordering. Standard sizes are useful for planning, but exact widths, depths, specialty configurations, and installation requirements vary by cabinet collection and manufacturer.

Practical Cabinet Sizing Tips

Plan around workflow, not just available wall space.

More cabinet depth does not always mean a better layout. Keep frequently used items easy to reach, and use deeper base or tall cabinets for larger cookware, pantry items, and less frequently used storage.

Use specialty storage when floor space is limited.

In a smaller kitchen, pull-out trays, drawer bases, narrow pantry cabinets, and well-planned corner storage can improve accessibility without increasing the overall cabinet footprint.

For a more complete comparison, see our guide to choosing the best cabinets for small kitchens based on storage needs, cabinet size, layout, and available space.

Choose tall cabinets as part of the full cabinet run.

An 84″, 90″, or 96″ pantry cabinet should align with adjacent wall cabinets, appliances, fillers, and trim. Do not choose the tallest cabinet simply because the ceiling is high enough.

Match vanity size to the bathroom layout.

A vanity that is too deep or too wide can interfere with doors, walkways, plumbing, and other fixtures. Confirm the available floor space, sink position, and door clearance before selecting the cabinet width and depth.

Use standard sizes as a starting point, not a guarantee.

Standard cabinet dimensions make planning easier, but every kitchen or bathroom is different. Verify the actual room measurements, appliance specifications, cabinet collection, and installation requirements before placing the final order.

Common Cabinet Sizing Mistakes to Avoid

Common Mistake	Why It Causes Problems	What to Do Instead
Ordering cabinets before confirming appliances	Refrigerator, range, microwave, oven, dishwasher, and sink dimensions vary by model	Confirm exact appliance and sink specifications before finalizing cabinet sizes
Measuring only wall-to-wall dimensions	Doors, windows, trim, uneven walls, plumbing, and electrical locations can affect the usable space	Measure the finished room and record all openings, obstructions, and utility locations
Choosing tall cabinets from ceiling height alone	Installation clearance, crown molding, soffits, and adjacent cabinet heights can change what actually fits	Check the entire cabinet run before selecting 84″, 90″, or 96″ tall cabinets
Forgetting fillers and finished panels	Cabinet-box widths alone may not equal the final installed width	Include fillers, panels, trim, and appliance clearances in the cabinet plan
Assuming every brand uses the same “standard” sizes	Cabinet widths, specialty depths, and configurations vary by manufacturer and collection	Verify the exact SKU dimensions before ordering
Ignoring finished aisle and door clearance	Islands, cabinet doors, appliance doors, and drawers can interfere with movement when open	Measure clearances from the finished cabinet or countertop edges and check door swings
Using cabinet dimensions without checking the countertop	Countertop thickness, overhang, sink cutouts, and backsplash details affect the finished layout	Coordinate cabinet dimensions with the final countertop and sink specifications

The most expensive cabinet sizing mistakes usually happen before installation begins. A cabinet may technically fit the wall measurement but still interfere with an appliance door, drawer, plumbing connection, countertop overhang, or adjacent cabinet.

Final Measurement Checklist Before Ordering

Confirm the finished wall-to-wall and floor-to-ceiling measurements.
Verify every appliance and sink model number.
Check cabinet widths, heights, and depths against the exact product specifications.
Include fillers, finished panels, crown molding, and trim.
Confirm door, drawer, and appliance-opening clearances.
Check countertop thickness, overhang, and sink requirements.
Review the complete cabinet run before placing the order

If any measurement is uncertain, verify it before ordering rather than assuming a standard size will fit.

Once the measurements and final cabinet list are confirmed, compare kitchen cabinet quotes using the same cabinet sizes, fillers, finished panels, appliance requirements, and installation scope.

Final Thoughts: Use Standard Cabinet Sizes as a Starting Point

Standard kitchen cabinet sizes make it easier to plan a layout, compare cabinet options, and coordinate cabinetry with countertops and appliances. However, these dimensions should be used as a planning reference rather than treated as universal specifications.

Base cabinets are commonly built around a 34.5″ box height and 24″ depth, wall cabinets commonly use a 12″ depth, and tall cabinets are often available in 84″, 90″, and 96″ heights. Exact widths, specialty cabinet dimensions, and installation requirements vary by manufacturer and cabinet collection.

Before placing an order, verify the finished room measurements, appliance and sink specifications, cabinet SKU dimensions, fillers, panels, trim, and installation clearances.

If you are still preparing your layout, follow our guide on how to measure your kitchen for cabinets before creating the final cabinet list.
