Over-the-range (OTR) microwaves are a popular kitchen appliance, designed to save space and provide a convenient cooking solution. They combine the functions of a microwave and a range hood, making them an ideal choice for smaller kitchens or those looking to maximize counter space. Understanding the standard dimensions of these appliances, particularly their width, is crucial when planning a kitchen remodel or replacing an existing unit. This comprehensive guide dives deep into the world of OTR microwaves, exploring their typical widths, factors influencing size variations, installation considerations, and more.
Understanding Standard Over-the-Range Microwave Widths
The most common width for an over-the-range microwave is 30 inches. This standard size is designed to fit seamlessly above most standard-sized ranges and cooktops. This is the dimension you’ll encounter most frequently when shopping for a new OTR microwave.
However, it’s essential to recognize that “standard” doesn’t always mean universal. There can be slight variations, usually within an inch or two, depending on the brand and model. While 30 inches is the most prevalent width, some models might measure 29 7/8 inches or 30 1/8 inches. These subtle differences are often intended to ensure a snug fit and accommodate minor installation adjustments.
Why 30 Inches is the Standard
The 30-inch standard is largely dictated by the dimensions of standard ranges and cooktops. Most ranges are manufactured to be 30 inches wide, and OTR microwaves are designed to align with this dimension, creating a visually appealing and functionally integrated cooking area. This standardization simplifies the installation process and ensures compatibility across different brands and models.
Beyond aesthetics, the 30-inch width also provides ample space for the microwave’s internal components, including the turntable, cooking cavity, and ventilation system. This size allows manufacturers to incorporate desirable features without compromising performance.
Beyond the Standard: Are There Other Widths Available?
While 30 inches is the most common width, it’s not the only option. You might encounter some OTR microwaves that deviate from this standard. These deviations are typically found in higher-end models or those designed for specific applications.
For example, some manufacturers offer compact OTR microwaves with widths slightly smaller than 30 inches. These models are often intended for smaller kitchens or apartments where space is at a premium. Conversely, some high-end models might be slightly wider than 30 inches to accommodate larger cooking cavities or more advanced features.
In addition, you might find older homes with different range sizes, and therefore may require searching for models that better fit the existing cabinet openings. It’s always important to measure your existing space before purchasing any new appliance.
Factors Influencing Over-the-Range Microwave Width
Several factors can influence the actual width of an over-the-range microwave. Understanding these factors can help you make an informed decision when selecting the right model for your kitchen.

What is the standard width of an over-the-range microwave?
The standard width for over-the-range microwaves is typically 30 inches. This dimension is designed to align with the standard width of most kitchen ranges and cooktops, creating a seamless and integrated look in your kitchen. While you might occasionally find slightly smaller models, the 30-inch width is by far the most common and widely available size.
It’s important to measure your existing range or the space above where you plan to install the microwave to ensure proper fit. Although 30 inches is standard, variations in cabinet construction or range size could necessitate a different width. Accounting for a small tolerance (e.g., a quarter of an inch) is always a good practice during the measurement process to avoid installation issues.
Besides width, what other dimensions should I consider when buying an over-the-range microwave?
Beyond width, you should definitely consider the height and depth of the microwave. Height typically ranges from 16 to 18 inches, impacting the clearance between the microwave and your cooktop. Insufficient clearance can hinder your ability to use tall pots or cook larger meals. Ensure you have enough vertical space for comfortable cooking.
Depth is also crucial, typically varying between 15 and 17 inches. A greater depth will protrude further from your cabinets, potentially impacting aesthetics and workflow in your kitchen. Consider the depth in relation to your upper cabinets and how it will affect your countertop space and ease of movement within the kitchen. Choose a depth that balances capacity with space constraints.
Are there any exceptions to the standard 30-inch width for over-the-range microwaves?
While 30 inches is the standard width, there are indeed exceptions. Some manufacturers offer narrower models, typically around 24 inches wide, designed for smaller kitchens or apartments with limited space. These smaller models might sacrifice some interior capacity but can be a good option when space is a primary concern.
Conversely, you might occasionally find wider models, although they are less common. These wider microwaves may be designed to accommodate larger cooking surfaces or provide more interior space. However, installing a non-standard width might require modifications to existing cabinetry or a custom installation, increasing the cost and complexity of the project.
How does the width of an over-the-range microwave affect its cooking capacity?
Generally, a wider over-the-range microwave doesn’t automatically guarantee a larger cooking capacity. While a wider exterior might allow for a slightly larger interior, other dimensions like height and depth play a more significant role in determining the overall cubic footage. Manufacturers can maximize capacity by optimizing the interior design, regardless of the external width.
Instead of solely focusing on the width, look at the stated cubic footage of the microwave, usually expressed in cubic feet. This measurement directly indicates the usable space inside the microwave and will give you a more accurate understanding of its cooking capacity compared to just the exterior width. Pay attention to turntable diameter as well; a larger turntable can accommodate bigger dishes.
Can I install an over-the-range microwave wider than my range?
Installing an over-the-range microwave that’s wider than your range is generally not recommended and can lead to both functional and aesthetic problems. The microwave is designed to vent above the range, and a wider unit might not effectively capture smoke and odors rising from the stovetop. This could result in poor ventilation and grease buildup on surrounding surfaces.
Furthermore, an overhanging microwave can create an unbalanced and awkward appearance in your kitchen. The visual asymmetry can detract from the overall design and might even make the kitchen feel cramped. It’s best to stick with a microwave width that matches or is slightly smaller than your range to ensure proper ventilation and a harmonious aesthetic.
What tools do I need to measure the space for an over-the-range microwave accurately?
To accurately measure the space for an over-the-range microwave, you’ll need a few essential tools. First and foremost, a reliable measuring tape is crucial. Choose one with clear markings and a locking mechanism to hold the measurement steady. You’ll also want a level to ensure your measurements are taken horizontally and vertically, guaranteeing accurate dimensions.
Additionally, consider using a pencil to mark measurement points on the wall or cabinets. This helps you keep track of your dimensions and avoid errors. If you’re unsure about the structural integrity of the wall or cabinets above your range, a stud finder can be useful for locating support beams. Accurate measurements are the foundation of a successful installation.
What happens if I purchase an over-the-range microwave that is too wide for my space?
Purchasing an over-the-range microwave that is too wide for your space can create a significant installation challenge. In most cases, you won’t be able to simply squeeze it in. You may need to modify your existing cabinets, which could involve cutting or removing sections of the surrounding cabinetry. This can be a costly and time-consuming process, and might require professional help.
If cabinet modification is not feasible or desired, your only option might be to return the microwave and purchase a smaller model that fits the available space. Always carefully measure your space and double-check the microwave dimensions before making a purchase to avoid these potential headaches. It’s better to err on the side of caution and choose a model that you know will fit comfortably.
