Welcome to our dishwasher dimensions and standard size guide including tips on how to measure for your next kitchen appliance.
Dishwasher dimensions are standard so they fit most kitchen designs unless you purchase a space-saver dishwasher designed for an apartment or an oversized model for a large kitchen. Still, there may be variations in the width, height, and depth of different styles and different brands of dishwashers.
Cabinet space reserved for a dishwasher may also have different dimensions and may need to be measured carefully. This article will describe the different dishwasher dimensions and how to choose the right one for your kitchen space.
Standard Dishwasher Dimensions
A standard dishwasher normally measures 24 inches wide, 35 inches high, and 24 inches deep with adjustable feet to allow for leveling and height adjustments.
To fit properly, the spacing between the cabinets and countertop where the dishwasher will be installed should be a bit larger than the dishwasher to allow room for installation.
Some dishwashers may measure 23 2/8 inches wide, 34 inches high, and 23 5/8 inches deep, even though they are considered standard, allowing for a bit of extra space to make installation easier.
How Much Space Do You Need Around a Dishwasher?
With a standard dishwasher that has dimensions matching the spacing between cabinets exactly, the risk is a difficult installation and possible damage to the dishwasher exterior or cabinets because of a tight fit.
Although recommendations favor the exact same cabinet opening width, height, and depth as the dimensions of the dishwasher, a small variation of 1/8th or ¼ of an inch all around is generally safe and could avoid an opening too small. If there is too much space after installing the dishwasher, wood strips or molding can be installed to finish off the opening and help keep the dishwasher in place.
How to Measure a Dishwasher Opening?
Measure the opening in the cabinets for the dishwasher by figuring out the width, height, and depth. Keep a piece of paper and a pencil ready so you can jot down the measurements.
For the width, use a measuring tape and place the end against the left side of the cabinet wall about halfway down from the top, then stretch it to the right side and note the width.
For the height, set the end of the measuring tape directly on the floor lined up with the edge of the countertop and extend it to the inside of the top surface noting the maximum height.
And for the depth, extend the measuring tape against the back wall of the cabinet opening and allow the metal tape to snap tightly into place to hold it taunt until you reach the outside edge of the surrounding cabinet.
Be sure the measuring tape does not sag when you extend it as this can change the dimensions and cause incorrect measurements.
Also, some measuring tapes are not as accurate as others, having a different starting point from the actual end. Be sure to check that the markings on the tape are correct.
Check all measurements for the cabinet opening twice. This will avoid the wrong measurements. As many carpenters say, “Measure twice, cut once.” You may not be cutting out the cabinet space, but a bit of wisdom helps to be sure you measured properly.
Small Dishwasher Dimensions
Small dishwashers may be needed when cabinet space is not large enough for a standard dishwasher such as installations in apartment-sized kitchens, tiny home kitchens, or older home kitchens that were not originally designed with a dishwasher and are being retro-fitted to add one.
These small dishwashers, or space-saving sized, match the height and depth of a standard dishwasher being 35 inches high and 24 inches deep, but they measure 18 inches or 17 5/8 inches wide.
A small dishwasher can fit into spaces 18 inches wide or larger. For larger openings, a small dishwasher would need to be framed to hide the extra space. Small dishwashers do just as good a job of cleaning dishes and can fit almost as much as a standard dishwasher.
Oversized Dishwashers Dimensions
Oversized dishwashers are available and typically found installed in modern residential homes that have large, restaurant-sized kitchens, for homeowners who use their kitchen often, or for large families.
These oversized dishwashers, as in smaller dishwashers, still have the same dimensions as standard dishwashers with a 35-inch height and 24-inch depth, but they range from 30 inches wide to 42 inches wide.
Cabinet spacing will need to be wide enough to accommodate these oversized dishwashers so accurate measurements will need to be done before purchasing.
