Shop DishwashersWhen 18” Is the Right Dishwasher Size
Sometimes, less really is more. An 18-inch dishwasher (often known as a compact dishwasher) is the go-to choice for kitchens where space is limited. These dishwashers fall into the narrow dishwasher width category, and they’re perfect for apartments, condos, or galley kitchens where every inch of cabinetry matters.
Beyond space efficiency, compact dishwashing machines work well for household with fewer members. Singles and couples often don’t create enough daily dishes to justify a full-size machine, and the small dishwasher width of compact models balance between convenience and efficiency. An 18 inch width dishwasher is also a smart choice for second kitchens, guest houses, or vacation homes where dish use is occasional, but reliable cleaning is still a must.

Why Most Homes Choose a 24” Dishwasher Size
If you’re wondering, “Are all dishwashers the same width and height?” the answer is simply no. However, most share a standard footprint.
The typical dishwasher width accommodates a standard dishwasher width of 24 inches, making it the most common pick for homeowners. This size balances generous capacity with a design that fits seamlessly into existing cabinetry.
If your current machine needs an upgrade, chances are the cutout in your cabinetry is already prepared for another of the same size. Because the plumbing and hookups are generally located next to the sink, sticking with the standard is usually the most straightforward and cost-effective choice. That’s why, for most households, a 24-inch dishwasher is a no-brainer.
About Dishwasher Capacity
When we discuss how to choose dishwasher size, we’re not just talking about physical dishwasher width sizes. Size can also refer to capacity, which is measured in place settings.
A place setting typically includes a dinner plate, salad plate, soup bowl, glass, teacup with saucer, and a set of cutlery (a knife, two teaspoons, dinner fork, and small salad fork). By understanding dishwasher capacity, you can quickly gauge how many dishes your dishwasher can handle in one cycle.
🟢Here’s how dishwasher capacities break down:
🟢8–10 place settings: This option is best for singles, couples, or very small households who typically don’t entertain.
🟢11–14 place settings: This capacity works well for couples who cook often or small but growing families.
🟢15–16 place settings: This is a reliable choice for standard households that need room for daily dish loads plus a little extra when company comes over.
🟢17+ place settings: The powerhouse option, a capacity of 17+ place settings is perfect for large families or those who entertain frequently. While limited to few brands, large dishwashers maximize every cycle and make sure nobody is stuck washing by hand.

Expert Tips | Choosing the Right Dishwasher Size
Even after narrowing down dishwasher widths, you’ll want to take a few extra steps to ensure your choice truly fits your kitchen and your lifestyle. Here are our top expert tips to guide your purchase.
Measure Your Dishwasher Cutout
Before choosing, you’ll need to measure for dishwasher installation. Here’s a step-by-step guide:
- Measure the width of your cutout from cabinet to cabinet. Note whether you’re working with a built in dishwasher width of 18 inches or the standard dishwasher width of 24 inches.
- Measure the height from the floor to the underside of the countertop. Standard dishwasher cutouts are typically around 34 inches tall, but double-check, especially if your flooring has been updated since your last dishwasher install.
- Measure the depth of a dishwasher cutout from the wall to the cabinet front. This ensures your new dishwasher won’t stick out awkwardly.
- Check clearance requirements. Dishwashers need enough space behind them for water and electrical connections. The installation guide from the manufacturer will provide exact clearance needs.
- Check door clearance. Make sure the door can open fully without hitting an island, wall, or cabinet. You can confirm this by looking at the model’s spec sheet for door swing dimensions.
Consider Your Lifestyle Needs
It’s easy to think bigger is always better, but that’s not the case. If your household doesn’t dirty dishes often, a large model may just waste water and energy. For smaller households, a compact model is more sustainable.
On the other hand, a family with kids or frequent dinner guests will quickly outgrow an 18-inch dishwasher. In this case, the typical dishwasher width of 24 inches with at least 15 place settings will serve you best. Matching your choice to your lifestyle ensures your dishwasher feels like a time-saving helper rather than an under- or oversized nuisance.
Make a Dishwasher Budget
One common misconception is that smaller dishwashers cost less. In reality, compact appliances often come with a higher price tag since they’re manufactured in lower quantities. So, while an 18 inch width dishwasher may save space, don’t expect it to save you money.
Don’t forget installation costs, either. Whether you choose compact or standard, there may be fees for removal, delivery, and setup. Planning a realistic budget ensures you won’t face surprises when you bring your new appliance home.
