No, over-the-range microwaves are not all the same size, though many models share a common width designed for compatibility with standard kitchen layouts. While a significant number of units are manufactured with a standardized width to fit above most ranges and within cabinet cutouts, there are notable variations in other dimensions, particularly capacity, and even alternative width options.
Key Dimensions of Over-the-Range Microwaves
Understanding the different dimensions is crucial for selecting the right over-the-range microwave for your kitchen.
1. Width Variations
The most common width for over-the-range microwaves is approximately 30 inches. This measurement is highly standardized to match the typical width of ranges or cooktops installed below them, as well as the standard cabinet cutout width where the microwave will be mounted. This consistency ensures a seamless, integrated look in most kitchens.
However, not all over-the-range microwaves adhere strictly to this measurement. You can also find compact models that measure around 24 inches wide, designed for smaller kitchens, apartments, or situations where space is limited.
2. Capacity Differences
Beyond external dimensions, the internal capacity of over-the-range microwaves also varies considerably. Capacity is typically measured in cubic feet and can range significantly, usually from about 0.8 to 2.1 cubic feet. A larger capacity generally means more interior space for cooking larger dishes or multiple items simultaneously, which can be a key factor for families or those who frequently cook big meals.
3. Height and Depth
While width is often the most standardized dimension, the height and depth of over-the-range microwaves can also differ between models and manufacturers.
- Height: Most models fall within a range of 16 to 18 inches. Differences in height can impact the clearance above your cooktop and the visual alignment with surrounding cabinetry.
- Depth: The depth typically ranges from 15 to 17 inches. This measurement is important for ensuring the microwave doesn't protrude too far into your kitchen space, maintaining a clean line with upper cabinets, and providing adequate ventilation.
Typical Over-the-Range Microwave Dimensions
Here's a breakdown of common dimensions you might encounter:
| Dimension | Common Range | Notes |
|---|---|---|
| Width | 24 inches | Compact models |
| 30 inches | Standard for most kitchens | |
| Capacity | 0.8 – 2.1 cu. ft. | Internal volume for cooking |
| Height | 16 – 18 inches | Varies by model and manufacturer |
| Depth | 15 – 17 inches | Varies by model and manufacturer |

Why Measuring is Essential
Given the variations, it's crucial to accurately measure your existing space before purchasing a new over-the-range microwave.
Consider the following:
- Width of the opening: Measure the distance between your upper cabinets.
- Height from the cooktop to the bottom of the upper cabinet: Ensure sufficient clearance.
- Depth of the upper cabinet: To ensure the microwave doesn't protrude too far.
- Ventilation requirements: Adequate space for proper airflow is necessary.
Choosing the correct size ensures proper installation, functionality, and a cohesive look with your kitchen cabinetry and appliances. For detailed installation instructions and precise measurements, always refer to the manufacturer's specifications for the specific model you are considering, often available on their websites like GE Appliances.
