What is the standard depth of kitchen cabinets? Standard kitchen cabinets come in typical sizes for both base (lower) and wall (upper) units. The standard kitchen cabinet depth for base cabinets, measured from the front face (excluding countertop overhang), is generally 24 inches. Wall cabinets, or upper cabinets, have a wall cabinet depth standard of about 12 inches. These are the most typical kitchen cabinet dimensions you will find in many homes.

Comprehending Standard Cabinet Depths
Most kitchens use cabinets that come in set sizes. This makes planning a kitchen easier. It helps manufacturers build them the same way. And it helps people installing them know what to expect. Cabinets come in different types based on where they go. The main types are base cabinets and wall cabinets.
Why Standard Sizes Matter
Using standard sizes is helpful for many reasons.
* Making things: Companies can build many cabinets the same way. This helps lower costs. It makes cabinets easier to find and buy.
* Planning kitchens: Kitchen designers use standard sizes. This helps them plan layouts quickly. It helps them know how things will fit. It makes sure appliances will work with the cabinets.
* Replacing cabinets: If you need to replace just one cabinet, it’s much easier with standard sizes. A new standard cabinet will likely fit the old spot.
* Countertops: Standard base cabinet depth is set up to work with standard countertop sizes. Countertops are usually a bit deeper than the cabinet box.
The Two Main Cabinet Types and Their Depths
Kitchen cabinets are mostly split into two groups: those that sit on the floor (base cabinets) and those that hang on the wall (wall cabinets). They have different jobs and different standard depths because of how they are used.
Base Cabinets
Base cabinets sit on the floor. They hold your counters. They are often deeper than wall cabinets. This is because they are closer to you when you are working at the counter. They also hold larger items like pots and pans.
The base cabinet depth standard is usually 24 inches. This measurement is from the very front of the cabinet door or drawer to the back of the cabinet box. But this 24-inch number is often more about the total space the cabinet takes up, including the door. The cabinet box itself might be slightly less deep, maybe 23 or 23.5 inches.
Why 24 inches? This depth works well with standard kitchen appliances like dishwashers, ranges, and refrigerators. These appliances are often around this depth. It also gives enough space for deep drawers and shelves to hold many kitchen items.
Remember that the countertop will stick out past the front of the base cabinets. This overhang is usually about 1 inch. So, the total depth from the front of the counter to the back of the cabinet is about 25 inches. This overhang protects the cabinet fronts from spills. It also makes the counter comfortable to lean against.
Base cabinets also have a standard height. The standard height for base cabinets, not including the countertop, is 34.5 inches. When you add a standard countertop (usually 1.5 inches thick), the total counter height is about 36 inches. This height is comfortable for most adults to work at.
Base cabinets also have a space underneath called a toe kick. This space is usually about 4.5 inches high and 3 inches deep. It’s set back from the cabinet front. This allows you to stand closer to the counter comfortably without hitting your toes. The depth measurement of the cabinet (24 inches) does not include the toe kick space sticking out but measures the main box part that sits above the toe kick area and goes back to the wall.
So, when we talk about the average base cabinet depth, 24 inches is the key number to remember for planning purposes, knowing the box is a little less. This standard cabinet depth measurement is a core part of kitchen design.
Wall Cabinets
Wall cabinets hang on the wall above the base cabinets. They are typically shallower than base cabinets. This is so you don’t hit your head on them while working at the counter. It also makes it easier to reach items inside.
The most common wall cabinet depth standard is 12 inches. This is measured from the front of the cabinet door to the back of the cabinet box.
However, wall cabinets come in more standard depths than base cabinets. You can often find standard wall cabinets in depths of:
* 9 inches (often used above refrigerators or microwaves, or in tight spots)
* 12 inches (the most common depth)
* 15 inches
* 18 inches
* 24 inches (less common, sometimes used above refrigerators or for specific needs)
The depth you choose for wall cabinets depends on what you plan to store and how much space you have. A 12-inch deep cabinet is good for plates, glasses, and typical pantry items. Deeper cabinets like 15 or 18 inches offer more storage space but might feel like they stick out too far for some people.
Wall cabinets also come in different standard heights. Common heights are 30 inches, 36 inches, and 42 inches. The height you pick depends on your ceiling height and how high you want to hang the cabinets above the countertop. Standard practice is to leave about 18 inches of space between the top of the countertop and the bottom of the wall cabinets. This gives you space for small appliances like toasters or coffee makers.
So, the upper cabinet depth standard is typically 12 inches, but other standard depths are available to fit different needs and spaces. Knowing this kitchen cabinet size guide helps you plan your upper storage.
A Quick Look at Tall Cabinets
Tall cabinets, like pantry cabinets or utility cabinets, go from floor to ceiling (or near ceiling). Their depth can vary.
* Some tall cabinets are designed to match the depth of base cabinets, around 24 inches. This is common for pantry cabinets that might have pull-out shelves or storage for bulk items.
* Other tall cabinets might be shallower, like 12 or 18 inches deep. These are useful in smaller kitchens or when you want a less bulky look. They are good for storing canned goods or cleaning supplies.
So, while not as strictly standardized as base or wall cabinets, tall cabinets often use depths similar to the other types, typically 12, 18, or 24 inches.
Exploring Depth Variations and Their Impact
While standards exist, not all kitchen cabinets are the same depth. Sometimes you might choose cabinets that are deeper or shallower than the typical sizes. There are good reasons for this.
Why Depths Change
Cabinet depths can change for several reasons:
* What you store: Some items need more depth than others. A deep drawer needs a deep cabinet box.
* Room size: A small kitchen might need shallower cabinets to make the walkway wider. A large kitchen might use deeper cabinets to fill space and add storage.
* How you use the kitchen: Do you need space for large appliances on the counter? Then you need enough space under the wall cabinets. Do you have a lot of large pots? You might want deeper base cabinets.
* Design style: Sometimes, mixing depths adds visual interest. Deeper cabinets on an island, or shallower cabinets on one wall, can be part of the look.
* Cabinet type: Stock cabinets usually only come in standard depths. Semi-custom or custom cabinets offer more choices in depth.
Deeper Than Normal Base Cabinets
While 24 inches is standard, some kitchens use deep kitchen cabinets for their base units. These might be 27, 30 inches, or even deeper.
Why choose deeper base cabinets?
* More Storage: This is the most common reason. An extra 3-6 inches of depth can make a big difference in how much you can store, especially in drawers. You can fit more items or larger items like serving platters.
* Island Storage: On kitchen islands, base cabinets might be deeper on one side or both sides. A common island depth is 36 or 42 inches. This allows for seating on one side and deep cabinets on the other.
* Special Pull-Outs: Some fancy pull-out storage systems work better in deeper cabinets.
* Appliance Fit: In some cases, a specific range or cooktop might require a slightly deeper cutout or space behind it, leading to deeper base cabinets around it.
Using deeper base cabinets gives you great storage. But they also take up more floor space. You need to make sure your kitchen is large enough to handle them without making walkways too narrow. The average base cabinet depth is 24 inches, but deeper options are a way to boost storage in the right space.
Deeper Than Normal Wall Cabinets
Standard wall cabinets are 12 inches deep. But you can often get standard upper cabinet depth standard options at 15, 18, or even 24 inches deep.
Why choose deeper wall cabinets?
* Better Storage: Like base cabinets, more depth means more storage space. A 15-inch deep wall cabinet can hold larger plates or serving bowls that might not fit in a 12-inch cabinet.
* Microwave Cabinets: Often, a cabinet designed to hold a built-in microwave will be deeper than the standard 12 inches, perhaps 15 or 18 inches. This allows the microwave to sit back further.
* Above Refrigerator: The cabinets installed above a refrigerator are often 24 inches deep. This lines them up with the depth of the refrigerator itself. This makes the space look cleaner and offers good storage for large, light items (since they are high up).
* Visual Interest: Sometimes, deeper cabinets are used next to shallower ones to create a varied look on a wall.
Deeper wall cabinets offer great storage, especially for larger items. But they can feel imposing, especially in a small kitchen. They also stick out further, potentially feeling closer to your head when you are at the counter. The wall cabinet depth standard of 12 inches is common because it balances storage and workspace comfort. But deeper sizes give useful options.
Shallower Cabinets
Sometimes, standard depths are too big. This is where shallow kitchen cabinets come in.
* Shallow Base Cabinets: These might be 18, 15, or even 12 inches deep.
* Why use them? In very narrow kitchens (like galley kitchens), shallower base cabinets leave more room for a walkway. They can also be used on one side of an island where storage isn’t the main need, but a counter surface is desired. They are also sometimes used in laundry rooms or garages, not just kitchens.
* Shallow Wall Cabinets: These are often 9 inches deep.
* Why use them? A 9-inch deep wall cabinet is great for storing things like spices, canned goods (single file), or small items. They are less likely to feel like they are in your way. They can also be used above windows or doors where a 12-inch cabinet would stick out too far.
Shallow cabinets are useful in tight spaces or for specific storage needs. They don’t hold as much as standard or deep cabinets. But they can make a small kitchen feel bigger and easier to move around in. The standard kitchen cabinet depth works for most cases, but shallow options solve specific space problems.
Choosing the Right Cabinet Depths for Your Kitchen
Picking the right cabinet depths is a key step in planning your kitchen. It affects how much you can store and how easy it is to move around and work.
Planning Your Layout
Before you choose cabinet depths, think about your kitchen space.
* Room size: How big is your kitchen? Measure the length and width. Draw a simple floor plan.
* Doors and windows: Mark where doors and windows are. Cabinets can’t go everywhere.
* Appliances: Note where your stove, refrigerator, sink, and dishwasher will go. These often need specific clearances. The depth of your refrigerator, for example, will affect how deep the cabinets next to and above it can be.
* Walkways: How much space do you need to walk through the kitchen? Experts often recommend at least 36 inches for a walkway, and more (42-48 inches) in work areas or main pathways. Deeper cabinets take up more walkway space. Shallower cabinets give you more.
* Countertops: Remember that standard base cabinets are set up for a standard countertop depth (about 25 inches total). If you use deeper base cabinets, you’ll need a deeper custom countertop.
Drawing your layout to scale helps you see how different depths will fit. Will a 27-inch deep base cabinet block a doorway? Will 15-inch deep wall cabinets hang too low above a window?
Matching Depth to Function
Think about what you will put in your cabinets.
* Deep pots and pans: These need deep drawers or shelves, often found in 24-inch standard base cabinets or deeper ones.
* Plates and bowls: Standard 12-inch wall cabinets usually work for most dinnerware. Very large platters might need a 15-inch wall cabinet or storage in a base cabinet.
* Small items: Spices, small jars, and cans fit well in 12-inch deep wall cabinets. For just spices, a 9-inch shallow wall cabinet is perfect as items don’t get lost behind each other.
* Bulk items: Items bought in bulk, like bags of flour or dog food, often go in a pantry or tall cabinet. A 24-inch deep pantry cabinet with pull-out shelves is great for this.
* Appliances: A stand mixer might go in a deep base cabinet with a lift. A microwave might need a deeper wall cabinet section.
Matching the cabinet depth to what you will store makes your kitchen work better. It helps you stay organized.
Standard vs. Deep vs. Shallow
When deciding on depth, consider these points:
* Standard Depths (24″ base, 12″ wall): These are the most common. They are usually the most affordable. They work well in most kitchens. They offer good storage for typical items. They are easy to plan around because appliances and countertops are designed for them. This is the go-to choice for most areas of the kitchen. This is your main kitchen cabinet size guide.
* Deeper Cabinets (e.g., 27″+ base, 15″+ wall): Choose these when you need extra storage for larger items. They are great for islands to add seating or extra storage. Use them if your kitchen is large enough to handle the reduced walkway space. They might cost a bit more, especially if they are not standard options from the cabinet maker. These are your deep kitchen cabinets.
* Shallow Cabinets (e.g., 12″-18″ base, 9″ wall): These are best when space is tight. Use them in narrow kitchens or hallways. They are good for specific storage like spices or single rows of cans. They give you more floor space. They hold less than standard cabinets. These are your shallow kitchen cabinets.
Mixing depths is fine, but plan it carefully. For example, you might use standard 24-inch base cabinets for most of the kitchen but use shallower ones on a small run or island. You might use standard 12-inch wall cabinets but have a deeper 15-inch one over the sink or a 24-inch one over the fridge. The key is to balance function, space, and how it looks.
A Quick Guide to Typical Cabinet Dimensions
Here is a summary of common standard dimensions for kitchen cabinets. Remember that actual sizes can vary slightly by manufacturer. Also, face frame cabinets might have slightly different internal depths than frameless cabinets, even if the outside dimension is the same.
| Cabinet Type | Common Depth (front to back) | Common Height (floor to top) | Common Width (side to side) | Notes |
|---|---|---|---|---|
| Base Cabinets | 24 inches (box often 23″ to 23.5″) | 34.5 inches (before countertop) | 9 to 48 inches (usually in 3-inch steps: 9, 12, 15, 18, 21, 24, etc.) | Includes toe kick space at bottom (approx. 4.5″ H x 3″ D set back). Countertop adds about 1″ depth overhang. |
| Wall Cabinets | 12 inches (most common) | 30, 36, 42 inches (most common) | 9 to 48 inches (usually in 3-inch steps) | Also commonly available in 9, 15, 18, 24 inch depths. Hung above counter, often leaving 18″ space. |
| Tall/Pantry Cabinets | 24 inches (to match base) | 84, 90, 96 inches (floor to ceiling/near ceiling) | 18 to 36 inches (usually in 3-inch steps) | Also available in shallower depths like 12 or 18 inches. Act like floor-to-ceiling storage. |
These are the most common measurements you’ll see in a kitchen cabinet size guide. The standard kitchen cabinet depth numbers – 24″ for base and 12″ for wall – are the key starting points for planning.
Installation Notes Related to Depth
Cabinet depth impacts installation in a few ways.
* Wall Placement: When installing wall cabinets, the depth affects how far they stick out from the wall. Make sure you have enough clear space below them (typically 18 inches from the counter). If mixing depths, plan where the deeper ones go. Often, they go on the ends or over appliances to look balanced.
* Base Placement: Base cabinets need to be level front-to-back and side-to-side. The 24-inch depth is designed to leave space behind the cabinet (about 1 inch) for pipes or wiring. This space also allows you to push the cabinet back slightly if your wall is uneven. Shims are used to make sure the front of the cabinets are perfectly aligned, even if the wall behind them isn’t straight.
* Countertop Fit: If you use non-standard depth base cabinets (deeper or shallower), you will need a custom countertop cut to fit that depth. Standard countertops are made for 24-inch base cabinets.
* Appliance Depth: Ensure your chosen cabinet depths work with your appliances. A standard depth range or dishwasher fits perfectly with 24-inch base cabinets. If you choose shallower base cabinets, standard appliances will stick out.
Measuring carefully and planning for installation details related to depth helps avoid problems.
Cabinet Types and Depth Options
The type of cabinet you buy affects the depth options available to you.
Stock Cabinets
- These are ready-made cabinets.
- They come in the most common standard sizes (24″ base, 12″ wall, standard heights and widths).
- Depth options are usually limited to these standard sizes. You won’t easily find a 27″ deep stock base cabinet or a 15″ deep stock wall cabinet, though some manufacturers might offer a few common variations (like 15″ deep wall or 18″ deep base).
- They are the most budget-friendly option.
- Availability is high; you can often buy them off the shelf or with short delivery times.
Semi-Custom Cabinets
- These cabinets offer more choices than stock cabinets.
- You can often change some dimensions, including depth.
- You might be able to order base cabinets deeper than 24 inches (e.g., 27″).
- You are more likely to find wall cabinets in a wider range of standard depths (like 9″, 12″, 15″, 18″, 24″).
- They offer more door styles, finishes, and storage features.
- They cost more than stock cabinets and take longer to order.
Custom Cabinets
- These cabinets are built specifically for your kitchen.
- You can get almost any size or depth you need.
- If you want a 30″ deep base cabinet, a 7″ deep wall cabinet, or a tall cabinet exactly 26.5″ deep, custom is the way to go.
- This gives you the most flexibility in design and storage.
- Custom cabinets are the most expensive option and have the longest lead times.
When thinking about deep kitchen cabinets or shallow kitchen cabinets outside the most common sizes, your cabinet type (stock, semi-custom, or custom) will determine if those options are available and at what cost. For typical homes using standard appliances and layouts, the standard cabinet depth measurement of 24″ base and 12″ wall from stock or semi-custom lines works very well.
Frequently Asked Questions About Cabinet Depth
Do all base cabinets need to be the same depth?
No, they do not have to be the same depth. While using the base cabinet depth standard of 24 inches for most cabinets is common and makes planning easy, you can use different depths in a kitchen. For example, an island might have deeper cabinets than the wall cabinets. Or a section of cabinets might be shallower if space is limited. Mixing depths can add visual interest or meet specific needs, but requires careful planning.
What is the standard countertop depth?
The standard depth for kitchen countertops is about 25 inches. This depth is designed to fit over the standard kitchen cabinet depth of 24 inches, leaving about a 1-inch overhang in the front. This overhang is important for protecting the cabinet fronts and for comfort when standing at the counter. If you use base cabinets deeper or shallower than 24 inches, your countertop will need to be custom-sized to fit.
Can I mix different wall cabinet depths?
Yes, you can mix different wall cabinet depths. This is a common design choice. For example, you might use the most common wall cabinet depth standard of 12 inches for most cabinets, but use deeper 15-inch cabinets over a sink or shallower 9-inch cabinets for spices. Just like mixing base depths, mixing wall depths needs careful planning to look good and work well.
Why are wall cabinets shallower than base cabinets?
Wall cabinets are shallower than base cabinets mainly for comfort and safety. Because they hang above the counter, making them shallow (like 12 inches) prevents you from hitting your head while working below them. It also makes it easier to reach items stored inside them. Base cabinets can be deeper (24 inches) because they are lower down and need to hold heavier, bulkier items and support deep countertops.
How does a toe kick affect base cabinet depth?
The toe kick is the recessed space at the bottom front of a base cabinet. It is usually about 4.5 inches high and set back about 3 inches from the cabinet front. The standard cabinet depth measurement of 24 inches for a base cabinet is measured from the front of the cabinet box (or door/drawer front) to the back. The toe kick is part of the overall cabinet structure at the bottom but doesn’t add to the 24-inch front-to-back depth of the main storage area. It’s a feature for user comfort, not a change to the primary depth measurement of the cabinet box itself.
