How Big Are Microwaves? Understanding Microwave Size and Dimensions
How Big Are Microwaves? The typical microwave oven’s exterior measures roughly 18-24 inches wide, 14-20 inches deep, and 10-14 inches high, but the internal cooking cavity varies considerably based on model type and wattage. Choosing the right size ensures optimal cooking performance and fits seamlessly into your kitchen space.
The Evolution and Ubiquity of Microwaves
From their accidental discovery during radar research to their current status as a kitchen staple, microwave ovens have revolutionized cooking. Their speed and convenience have made them indispensable for reheating leftovers, preparing quick meals, and even cooking entire dishes. Understanding the factors influencing microwave size is key to selecting the right appliance for your needs. Microwaves have evolved from bulky industrial machines to sleek, counter-top appliances.
Factors Influencing Microwave Size
Several factors dictate the dimensions of a microwave oven. These include:
- Internal Cavity Size: This is the usable space inside the microwave, measured in cubic feet (cu. ft.). Larger families or those who frequently cook large meals will benefit from a larger cavity.
- Wattage: Higher wattage microwaves generally cook faster and more evenly. Higher wattage often correlates with a larger overall size to accommodate the larger components required.
- Type of Microwave: Countertop, over-the-range (OTR), built-in, and drawer microwaves each have different size profiles dictated by their installation and intended use.
- Features and Technology: Features like convection cooking, sensor cooking, and inverter technology can influence the size and weight of the microwave.
Types of Microwaves and Their Typical Dimensions
Different types of microwaves cater to varying needs and kitchen layouts. How Big Are Microwaves? depends on the type.
-
Countertop Microwaves: These are the most common and versatile type. They sit on a countertop and are available in a wide range of sizes and wattages.
-
Over-the-Range (OTR) Microwaves: These are installed above the range or cooktop and serve as both a microwave and a range hood.
-
Built-In Microwaves: These are designed to be integrated into cabinetry for a seamless, custom look.
-
Drawer Microwaves: These are installed below the counter and open like a drawer, offering a unique and space-saving design.
The following table provides typical dimensions for each type:
| Type of Microwave | Width (inches) | Depth (inches) | Height (inches) | Internal Capacity (cu. ft.) |
|---|---|---|---|---|
| Countertop (Compact) | 17-20 | 13-16 | 10-12 | 0.5 – 0.9 |
| Countertop (Mid-Size) | 20-24 | 15-18 | 12-14 | 1.0 – 1.6 |
| Countertop (Large) | 24+ | 18+ | 14+ | 1.7+ |
| Over-the-Range (OTR) | 29-30 | 15-17 | 16-18 | 1.5 – 2.2 |
| Built-In | 24-30 | 20-24 | 18-22 | 1.2 – 2.0 |
| Drawer | 24-30 | 20-24 | 15-18 | 1.0 – 1.2 |
Measuring Your Space Before You Buy
Before purchasing a microwave, it’s crucial to measure the available space in your kitchen. For countertop models, measure the width, depth, and height of the area where you plan to place the microwave. For OTR and built-in models, carefully measure the dimensions of the existing cabinet opening. Account for any necessary clearances for ventilation and door opening. Failing to accurately measure can lead to frustration and the need for returns.
Common Mistakes When Choosing a Microwave Size
- Underestimating Internal Capacity: Consider the size of the dishes you typically use. A microwave that looks large on the outside might have a surprisingly small internal cavity.
- Ignoring Ventilation Requirements: Microwaves need adequate ventilation to prevent overheating. Ensure there is sufficient space around the microwave for airflow.
- Forgetting About Door Clearance: Ensure the microwave door can fully open without hitting cabinets or other appliances.
- Neglecting Electrical Outlet Placement: Ensure there is a nearby electrical outlet within reach of the microwave’s power cord. This is a common oversight during planning.
Frequently Asked Questions (FAQs)
How Big Are Microwaves? These common questions can help you choose the right size.
What is the standard size for a countertop microwave?
The standard size for a countertop microwave typically falls within the mid-size range, with dimensions of approximately 20-24 inches wide, 15-18 inches deep, and 12-14 inches high. The internal capacity usually ranges from 1.0 to 1.6 cubic feet. These models offer a good balance of size and cooking capacity for most households.
What size microwave is best for a small apartment?
For a small apartment, a compact countertop microwave is often the best option. These models typically have a width of 17-20 inches, a depth of 13-16 inches, and a height of 10-12 inches. Their smaller size makes them ideal for tight spaces while still providing sufficient cooking functionality.
How do I measure the internal capacity of a microwave?
The internal capacity of a microwave is measured in cubic feet (cu. ft.). This measurement indicates the usable space inside the microwave oven. Manufacturers typically provide this specification in the product description or specifications.
What is the difference between a compact, mid-size, and large microwave?
The primary difference lies in their dimensions and internal capacity. Compact microwaves are the smallest, offering limited cooking space. Mid-size microwaves strike a balance between size and capacity, suitable for most households. Large microwaves provide the most cooking space, ideal for families or those who frequently cook large meals. The specific needs of the household dictate the best choice.
How important is the wattage of a microwave compared to its size?
Wattage and size are both important considerations. Higher wattage microwaves generally cook faster and more evenly, but a larger cavity allows you to cook larger dishes. Ideally, you want a balance of both wattage and size to meet your cooking needs.
Can I put a countertop microwave inside a cabinet?
It is generally not recommended to place a countertop microwave inside a cabinet without proper ventilation. Countertop microwaves are designed to have adequate airflow around them to prevent overheating. Enclosing them in a cabinet without sufficient ventilation can pose a fire hazard.
What are the advantages of an over-the-range (OTR) microwave?
OTR microwaves save counter space by combining the functions of a microwave and a range hood. They are a good option for kitchens where space is limited.
What is the difference between a built-in microwave and an OTR microwave?
Built-in microwaves are designed to be integrated into cabinetry for a seamless, custom look, while OTR microwaves are installed above the range or cooktop and also serve as a range hood. Built-in models are generally more expensive than OTR models.
Are drawer microwaves a good option for small kitchens?
Drawer microwaves can be a good option for small kitchens as they save countertop space. They offer a unique and modern design while maintaining functionality.
What size microwave do I need for a family of four?
For a family of four, a mid-size or large microwave with an internal capacity of 1.2 to 1.7+ cubic feet is typically recommended. This size provides sufficient space for cooking larger meals and reheating leftovers. Consider your specific cooking habits when making your final decision.
How do I know if a microwave will fit in my existing space?
Carefully measure the width, depth, and height of the available space and compare those measurements to the exterior dimensions of the microwave. Account for any necessary clearances for ventilation and door opening.
Are larger microwaves more energy-efficient?
Not necessarily. Energy efficiency depends on the wattage and features of the microwave, not solely on its size. Look for microwaves with energy-saving features like inverter technology. Energy Star-certified models are a great option to consider for energy efficiency.
