Thinking about upgrading your dishwasher?
Before diving into sleek new features like Wi-Fi connectivity and specialized wash cycles, it’s essential to understand standard dishwasher dimensions.
Choosing the right size ensures a perfect fit and hassle-free installation in your kitchen.
In this guide, we’ll break down the most common dishwasher sizes, explain how to measure your space, and highlight top dishwashers to consider. Whether you’re replacing an old unit or planning a kitchen remodel, this dishwasher size guide will help you shop smarter.
How to Measure Dishwasher Dimensions in Inches
Before shopping for a new dishwasher, it’s crucial to measure your available space to ensure a proper fit—especially if you’re replacing an existing unit. Most dishwashers are designed to fit within standard cabinet openings, typically located next to the kitchen sink for easy access to water and drain lines.
Follow these steps to measure for a dishwasher:
- Width: Measure the space from cabinet to cabinet, left to right. The standard width for most built-in dishwashers is 24 inches, but the actual unit will be slightly smaller (around 23.75") to allow for easy installation.
- Height: Measure from the floor to the bottom of the countertop. Standard height is about 34 inches, but adjustable legs can help accommodate slight differences.
- Depth: Measure from the back wall to the front edge of the cabinet. Most dishwashers are around 24 inches deep, but ensure there's enough clearance for the door to open fully.
Pro Tips
- You don’t need to leave space behind the dishwasher—most water and drain lines run through the adjacent cabinet.
- Electrical outlets are typically located in the back corner or under the sink, so they won’t interfere with depth measurements.
With your measurements in hand, you’re ready to find a dishwasher that fits your kitchen perfectly. Below is a helpful table of standard dishwasher dimensions to guide your selection.
