### How to Measure a Dishwasher: A Comprehensive Step-by-Step Guide
Purchasing a new dishwasher can transform your kitchen experience, saving you time and effort on daily chores. However, ensuring it fits perfectly requires precise measurements. Whether you’re replacing an old unit or installing one in a new space, knowing how to measure a dishwasher correctly is essential. This detailed guide walks you through every step, offers expert tips, and expands on related considerations to help you choose the right appliance with confidence.
#### Why Accurate Measurements Matter
Accurate measurement is crucial for dishwasher installation to ensure a seamless fit and optimal performance. As noted by Slyman Bros., “Taking precise measurements can prevent fitting issues, reduce installation headaches, and guarantee that your new appliance works efficiently” ([(( Slyman Bros Blog ))]). An ill-fitting dishwasher can lead to operational problems, wasted space, or even the need for costly returns. This guide will help you avoid those pitfalls by providing a clear, actionable process.
#### Tools You’ll Need
Before you begin, gather these basic tools:
– **Measuring tape**: Opt for one with 1/8-inch or 1/16-inch increments for precision.
– **Level**: Useful to check if the space is even, ensuring accurate readings.
– **Notebook and pen**: Record measurements to avoid relying on memory.
– **Optional**: A smartphone to photograph the space or measurements for reference.
Having these on hand simplifies the process and ensures consistency.
#### Step-by-Step Guide to Measuring a Dishwasher
##### Step 1: Measure the Height
The height determines if the dishwasher will fit under your countertop. According to KitchenAid, “Measure the distance between the lowest point of your countertops and the floor. Measure the farthest point near the back of the opening and the front of the opening” ([(( KitchenAid Guide ))]). Here’s how:
– Place the tape measure on the floor at the back left corner of the opening.
– Extend it vertically to the underside of the countertop and note the measurement.
– Repeat at the back right corner and the front of the opening.
– Use the smallest measurement if there’s variation due to uneven flooring. Most standard dishwashers require a height of 34½ to 36 inches, but adjustable feet can compensate for slight differences.
**Tip**: If new flooring has been added elsewhere in the kitchen but not under the dishwasher, the floor height may differ. Measure from the actual dishwasher space floor.
##### Step 2: Measure the Width
The width ensures the dishwasher fits between cabinets or walls. Whirlpool advises, “Measure from cabinet to cabinet, making sure that the sides of your dishwasher will be completely enclosed once installed” ([(( Whirlpool Guide ))]). Follow these steps:
– Measure the distance between the inner edges of the cabinets at the top of the opening.
– Repeat the measurement at the bottom to account for any tapering.
– Record the smaller of the two measurements to ensure a snug fit. Standard dishwasher width is typically 24 inches, though the actual unit may be slightly smaller (e.g., 23½ inches) to fit the opening.
**Note**: Leave a little breathing room—about ¼ inch on each side—to avoid a tight squeeze.
##### Step 3: Measure the Depth
Depth confirms the dishwasher won’t protrude awkwardly or lack clearance. The Home Depot explains, “Measure the distance from the back of the cabinet opening to the front of the cabinets or countertop” ([(( Home Depot Guide ))]). Here’s the process:
– Measure from the back wall of the opening to the front edge of the cabinets on the left side.
– Repeat on the right side and use the smaller measurement if they differ.
– Standard depth is around 24 inches, but account for handles or panels that may extend this slightly.
**Pro Tip**: Check for pipes or electrical outlets at the back and subtract their depth from your total to ensure clearance.
##### Step 4: Check Door Clearance
Don’t overlook the space needed to open the dishwasher door. Maytag recommends, “Make sure there is at least 27 inches of open space in front of the dishwasher for loading and unloading” ([(( Maytag Guide ))]). Measure:
– The distance from the front of the cabinet to any opposing counter, island, or wall.
– Ensure at least 27 inches of clearance to comfortably load and unload dishes without obstruction.
#### Understanding Standard Dishwasher Sizes
Dishwasher sizes vary, but most fall into a few common categories:
– **Standard Built-In**: 24 inches wide, 24 inches deep, 35 inches high. Fits most modern kitchen layouts.
– **Compact**: 18 inches wide, 24 inches deep, 35 inches high. Ideal for small kitchens or apartments.
– **Oversized**: 30–42 inches wide, same depth and height as standard models. Great for large households.
– **Portable**: 24 inches wide, 27 inches deep, 37 inches high. A mobile option not requiring cabinet space.
JennAir notes, “While 24 inches wide is considered the standard size for a built-in dishwasher, there can be variations in the heights and depths of dishwasher models” ([(( JennAir Guide ))]). Always check the manufacturer’s specs for exact dimensions.
#### Additional Considerations
##### Access Points
Before buying, measure doorways and hallways the dishwasher must pass through. Coast Appliances warns, “Check narrow hallways and doorways along the delivery path to ensure that the delivery team can gain access” ([(( Coast Appliances Guide ))]). A standard 24-inch-wide unit might not fit through a 22-inch doorway!
##### Utility Connections
Note the location of water, drainage, and electrical hookups within the opening. KitchenAid advises, “Utility connections vary by dishwasher model so make note of the connection location within your cabinet opening to plan ahead” ([(( KitchenAid Guide ))]). Ensure these align with your new unit’s requirements.
##### Flooring Variations
If your kitchen floor has multiple layers (e.g., tile over original flooring), the height under the dishwasher may differ from the rest of the room. Measure directly in the opening to avoid surprises.
#### Tips for Choosing the Right Size
– **Slightly Smaller is Better**: If your opening is non-standard, opt for a dishwasher ¼ to 1 inch smaller in width or height. Gaps can be filled with insulation or trim.
– **Capacity Needs**: Consider your household size. A standard 24-inch model typically holds 12–14 place settings, while compact models handle 6–10.
– **Check Features**: Beyond size, explore features like adjustable racks or energy efficiency that suit your lifestyle.
Consumer Reports suggests, “Take a close look at the configuration of the dishwasher’s interior to make sure the rack design will accommodate your dishes” ([(( Consumer Reports Guide ))]).
#### Common Mistakes to Avoid
– **Measuring an Installed Unit**: Measure the empty opening, not an existing dishwasher, for accuracy.
– **Ignoring Handles**: Depth specs often exclude protruding handles—factor these in.
– **Forgetting Clearance**: A dishwasher that fits the opening but blocks movement is impractical.
