Standard Kitchen Cabinet Sizes
There are some standard kitchen cabinet sizes, and standard appliance sizes.
Whether you purchase stock (factory built) cabinets or custom cabinets makes the difference on how flexible those standards can be. Custom built cabinets,
depending on who you have build them, can virtually eliminate the need for any
fillers, utilizing all your space.
Custom cabinets can also easily be built to accommodate
appliances that vary from the norm, like an oversized stove or refrigerator.
They can be built in 1/16" increments, even 1/32nds, so, even though there are "standards",or rules of thumb, there really are no standard kitchen cabinet sizes for custom cabinets.
Stock cabinets are normally built in 3" increments. The same goes for
semi-custom cabinets, which are really stock (factory built) cabinets with a few
more storage options. Check with your cabinet sales person as to what the semi-custom "standard kitchen cabinet sizes" are for sure, because each company may vary a little.
Although you will be somewhat limited regarding dimensions and sizes if you are purchasing
stock cabinets or semi-custom cabinets, the good news is, if you know what you
want and the dimensions of your room, you can easily find stock cabinets to fill
your area effectively and to your liking. Be aware that you may have to
use fillers in some areas that you wouldn't have to with custom cabinets.
STARTING WITH THE BASICS
Standard kitchen cabinet sizes are as follows:
- Base cabinets - 24" deep, 34 1/2" tall
- Upper cabinets - 12" deep and usually 30"
or 42" tall
* Please note that almost all stock cabinets will
come in 3" increments regarding width (9", 12", 15", etc.,
usually up to 36", sometimes more)
STANDARD KITCHEN CABINET SIZES: BASE CABINETS AND ISLANDS
A 24" deep base cabinet is the perfect size to accommodate your countertops.
surface, or quartz countertops will normally come 25 1/2" deep for kitchens. This allows for an 1 1/2"
overhang on the front.
If you are incorporating a simple island, 24" deep cabinets allow a standard 36" island countertop to be used. You will have an 1 1/2" overhang on the front
side of your island, and
a 10 1/2" overhang on the back side. This overhang on the back is for your knee area while seated, in other words, an eating area overhang. These are
standard sizes. You can get countertops in other sizes, but there will be
Lets say you want an extra-deep island; instead of 36" of countertop space,
you prefer 48" in
overall depth. If you want your eating area to have a 10 1/2" knee space (overhang) on the back side
of the island, you will need to do something creative. If you are purchasing stock cabinets,
order a normal 24" deep base cabinet, then add a 12" upper cabinet to the
back side of that. This results in 36" of total cabinet depth,
leaving you 12", of the 48" countertop, available
for overhangs (1 1/2" in front and 10 1/2" in back).
Keep in mind a 48" deep countertop is more expensive than a 36" and will probably have an added up-charge because of the extra depth. These types of extra-deep islands
work well in kitchens where you'll be putting the stove, cook-top, or sink in
Also, if you do this, make sure you know the exact height of the 12" upper
cabinet you will be using on the back side. With a base cabinet that is 34 1/2" tall, and an upper
that's 30" tall, you will have to add an appropriate height toe kick to make up
this difference. You could also add a filler to the upper cabinet's top, which will fill in the needed space.
The two cabinets must match in height, or your countertops won't work.
If you are purchasing custom built kitchen cabinets, this really isn't an
issue. Your cabinet maker (or designer) will sit down with you, discuss
your needs, and build a cabinet area to fit your specifications without having
to piece together pre-built pieces.
An alternative to having an extra-deep countertop to accommodate a stove or sink
in an island is to use standard kitchen cabinets sizes against a wall. Use a normal base cabinet with a depth of 24", and put a normal depth countertop (25 1/2") up against a 42" to 44" wall.
The photo at right shows a shaker maple kitchen like this. There is a bar
sink at the end of the island. The raised eating area allows for plug-ins
in the wall (the ones pictured are mounted sideways so the eating area doesn't
become too high).
On top of the short wall behind the cabinets, an eating area with 15" to 21"
countertop space can be used. The next photo at
right shows the back side of this island. We surrounded the backside with 1/2" maple veneer thermal-melamine. We then nailed 3" wide solid
maple boards on top. This gave it a shaker look to match the rest of the kitchen. It
would be easier to leave the 1/2 wall just sheetrock, but I don't think it looks
quite as nice as this.
Make sure your raised eating area is not too high, 42" to 44" works best. Some people think, oh, just go 4 feet, but a 48" high wall with
1 1/2" high countertop added to it becomes 49 1/2" high. This is way too
high for the average person to feel comfortable sitting at, even on high bar
Any kind of island wall will need electrical plug-ins too, to meet your local
housing codes. Plug-ins can usually be easily built into your wall
sideways. Laminate countertops with a standard backsplash are 39" high.
A sideways plug-in will take another 3" or so, making your countertop 42" high
at minimum. With 1 1/2" of countertop added to the top of the wall, you're
now at 43 1/2" without even leaving room for leveling the cabinets. If you were to
leave the plug-ins at their normal height, your wall would again be way too high
to sit at.
The countertop for peninsulas can be a bit tricky. On one side you
will have a normal 25 1/2" countertop. This will usually butt up to a 36"
deep countertop. Usually this will happen at a 90 degree angle, but not
always. 45 degree and 22 1/2 degree angles are also common in today's
If you have a standard laminate countertop, you will normally have a 3"
backsplash on the 25 1/2" part. Be sure to order this countertop
"bull-nosed" at your miter joint (where it attaches to the 36" countertop).
If you or your cabinet salesperson does not order this correctly, your
backsplash will look odd and not be finished correctly.
The standard kitchen cabinets sizes for peninsula cabinets are 24 1/2" depth, just like the rest of your kitchen. There are
two things to keep in mind:
- Be sure you order or have your cabinet maker
include a finished side to your peninsula back (you don't want to be looking
at an unfinished cabinet back from your living room, etc.)
- Avoid "blind" corners in your peninsula by
having a lazy susan area in the corner of your peninsula, or a regular
cabinet, 24 1/2" deep and 24" wide, pushed into the back side corner of your peninsula for
access from the "back" of the peninsula.
BUMPED OUT SINK AREA
Bumped out sinks are popular in different areas of the country, but are not
very practical unless you have a disability and can only access the sink area
from a wheelchair. If this is the case, either be sure to leave the sink
area open underneath the countertop, or, when you open the sink doors, be sure
there is not a middle support frame in your way.
Often sink bump outs are for looks. With that extra bump out area, you
can add a decorative piece of trim in the cabinetry for sophistication.
Keep in mind sink bump outs in countertops are an added expense, as well as more costly to install.
* Standard kitchen cabinet sizes for
a standard sink cabinet will be 36" wide to
accommodate the most common double bowled sinks (21" deep x 32" wide), and
again, 24 1/2" deep.
In the factory cabinet world, standard kitchen cabinet sizes for upper cabinets are normally 12" deep, with the width starting at 9" and going up in 3" increments. The
exception is refrigerator cabinets which can be 24" deep (and 12 or 15" high).
Custom built cabinets are often 14" deep. This is especially true for
laundry room areas (to allow for soap boxes), or in kitchens where the home
owner envisions using 12" plates, or just wants the added room.
Standard kitchen cabinet sizes regarding the height of uppers are either 30" high
or 42" high. There are variations to this in stock cabinets. Some
are now built 36" high to allow for slightly staggered heights, as well as 24" high.
Stock cabinets for above your stove normally come 15" high, but can be 18" high
as well. Don't use an 18" high cabinet above your stove if you'll be
installing a microwave above the stove. There won't be enough clearance
between your stove and microwave.
For standard kitchen cabinet sizes in the custom cabinet world of uppers, anything goes. Even if you have 9
foot ceilings, you can have cabinets built 54" high to go right up to the
ceiling without any splices. If you purchase stock cabinets and wish to fill the space of a 9
foot ceiling, you will have to purchase two cabinets and stack them one on top
of the other, usually a 42" and a 12", or a 30" and a 24".
Stock, or factory built bath vanities are 28 1/2" tall. This results in
a 30" high cabinet when standard 1 1/2" thick laminate countertops are added.
If you install a marble top, which is usually 3/4" thick, you will have a 29
1/4" high cabinet.
Custom built cabinets often build higher bath vanities, although you may need
to ask them to do this. It's nice to have a bath vanity so the final
height is 33" or 36" high, unless, of course, you have small children.
Important Note about Bath Vanity Heights:
Be sure to let your electrician and plumber know if you are raising bath
vanity heights, before they begin their work. They will most likely have
to move where they planned plug-ins and plumbing (or where your blue-print
says to put the plug-ins and plumbing). You don't want to go to install
your cabinets, and a plug-in sits where the back-splash for your bath vanity is
going to be.
If everything is in place, sheet-rocked, and painted before you realize the
error, it's often too late to fix
without doing some major damage to your walls, your time-frame, and budget (purchasing a different
cabinet or re-sheet-rocking and painting).
Standard kitchen cabinet sizes correlate with standard sizes for kitchen appliances. The standards for kitchen appliances are:
- Stove (free-standing): 30" (you can get
special order models that are 42", 46", 48", etc.) Keep in mind that
most units are 25" deep, plus their oven door handle
- Drop-in stove: usually 30", but can vary.
You will need to be extra careful when ordering your countertop. Be sure
to have your drop-in-stove dimensions. They will usually include
directions as to what kind of space is needed in your countertop.
- Cook Tops: Usually vary from 30" to
36" wide and are cut-into the countertop.
- Refrigerator: vary, can be 30" wide to 48"
wide for commercial type models. They can be 67" high or higher.
Most side by sides today are 35 7/8" wide require 70" of space before an upper
cabinet can be placed. Standard dimensions for kitchen cabinets
regarding refrigerator openings are 36" wide.
- Dishwashers: 24" (unless you special order
an 18", which I wouldn't recommend unless you absolutely have to because you
are remodeling and that is all the space you have - 18" dishwashers not only
loose 6" of space, but are more expensive than standard 24" dishwashers)
- Microwaves - above the stove: 30" (just
like a range hood), however, microwaves on the counter or built into a cabinet
can come in almost any size. Please keep in mind microwaves that go over
your stove come in slightly different heights, and may need to be built out
from the wall (to ensure the air from the fan is not blowing directly onto
your cabinets, thus discoloring or removing the finish from your cabinetry
over time - if someone else is installing your over-the-stove microwave, be
sure they do this if necessary).
- Compactor: usually 15 to 18" wide
- Built-in Wall Ovens: Vary.
Make sure you have the dimensions before you order your stock cabinets, or
have your cabinet maker build a unit.

You can't always go off of the blue-print if you're building a new home.
They might not draw the kitchen cabinets correctly, the sizes of your walls will
change slightly, or you might want to make minor or major changes to the kitchen
layout. Here's where you have to trust your custom cabinet maker, kitchen
cabinet sales person, or yourself if you've building your own cabinets.
Your kitchen will have to be measured once all the walls are where they are
going to be. The measurements must be accurate.
If a custom cabinet maker or your cabinet sales person makes a mistake in
measuring, and the standard kitchen cabinet sizes that they order don't fit,
it's their problem. Don't let them make you pay for rebuilding or
reordering cabinets or countertops.
