To measure what size dishwasher you need, accurately assess the width, height, and depth of the installation space in your kitchen. The most critical measurement is the width, as this determines if the dishwasher will fit between your existing cabinetry.
How to Measure What Size Dishwasher?
Determining the correct dishwasher size involves precise measurements of the opening where the appliance will be installed. This ensures a seamless fit and proper operation.
1. Measure the Width
The width is the most important measurement for a built-in dishwasher.
- Process: Measure the width of the space where you want to install the new dishwasher. This measurement is the distance between the two cabinets or walls where the dishwasher will be installed. To ensure the dishwasher fits, measure at the narrowest point to determine the maximum width of the dishwasher that will fit in the space.
- Standard Size: Most full-size dishwashers are 24 inches wide.
- Compact Size: Smaller, compact dishwashers are typically 18 inches wide.
2. Measure the Height
Next, measure the vertical space available.
- Process: Measure from the floor to the underside of your countertop. Dishwashers often have adjustable leveling legs, which allow for minor height adjustments.
- Standard Range: Standard dishwasher heights usually fall between 33.5 to 34.5 inches. Ensure your opening accommodates this range, accounting for any flooring variations.
3. Measure the Depth
The depth measurement ensures the dishwasher won't protrude too far from your cabinetry.
- Process: Measure from the back wall to the front edge of your cabinets. This measurement should account for any plumbing or electrical connections behind the appliance.
- Standard Range: Most dishwashers are designed to fit flush with standard 24-inch deep cabinets, typically having a depth of 24 to 25 inches. Remember to allow extra space for the water line, drain hose, and electrical cord.
Standard Dishwasher Dimensions
Understanding typical dimensions can help you visualize the space requirements.
| Dishwasher Type | Width (Approx.) | Height (Approx.) | Depth (Approx.) |
|---|---|---|---|
| Standard | 24 inches | 33.5 - 34.5 inches | 24 - 25 inches |
| Compact | 18 inches | 33.5 - 34.5 inches | 24 - 25 inches |
| Drawer | 24 inches | 17 - 24 inches | 24 - 25 inches |
Note: Dimensions can vary slightly by manufacturer. Always check the specific product specifications.
Additional Considerations for Installation
Beyond the primary dimensions, keep these points in mind for a smooth installation:
- Utility Access: Ensure there is easy access for the water supply line, drain hose, and electrical outlet (usually a dedicated 15-amp circuit). Consult resources like Energy Star's appliance guides for utility requirements.
- Door Clearance: Measure to ensure the dishwasher door can open fully without hitting an island, cabinets, or other appliances. You'll need about 27-28 inches of clearance in front of the dishwasher.
- Flooring: If you plan to change your flooring, consider how it might affect the height clearance. Installing a dishwasher before new flooring can prevent future height issues.
- Capacity: Dishwasher capacity is often measured in "place settings." A standard 24-inch dishwasher typically holds 12-14 place settings, while compact models hold 6-8. Choose a capacity that suits your household's needs. Learn more about capacity at sites like Consumer Reports.
By taking careful measurements and considering these factors, you can confidently select a dishwasher that fits perfectly into your kitchen.
