How to Measure Microwave Oven Size [2024]

If you’re in the market for a new microwave or just need to check if your current microwave will fit in a redesigned kitchen space, knowing how to measure microwave size is crucial. Whether you have a compact microwave that sits on the countertop or a sleek built-in model tucked into a cabinet, the process involves a few key steps. First, grab a measuring tape because precision is key here, especially if you’re dealing with tight spaces between the microwave and other appliances or features like a vent.

How to Measure Microwave Oven Size? To measure a microwave oven’s size, determine the interior dimensions: width, depth, and height, usually listed in liters or cubic feet. Measure from the inner edges to account for the actual cooking space. Exterior dimensions are also important for fitting the appliance in its designated space.

For those looking to upgrade, understanding the dimensions of over-the-range microwaves can ensure that your new microwave will not only fit but also function well with enough room for ventilation. Also, if you’re considering a built-in microwave, you’ll need to be mindful of the cubic feet and overall size to avoid a tight squeeze or a mismatch in your kitchen’s layout. This practical guide will make sure you’re all set whether you’re measuring for replacement, planning to haul-away the old appliance, or installing a brand-new microwave.

How to Figure Out Your Microwave Size: From Compact to Over-the-Range Models

How to Figure Out Your Microwave Size: From Compact to Over-the-Range Models

When you’re looking to size up a new microwave, whether it’s a compact model for a tight space or an over-the-range type, knowing how to measure it right can save you a lot of headaches. First things first, you’ll need to decide on the microwave type you want because different microwave types fit differently. For a built-in, check the standard cabinet dimensions where you plan to install it. If it’s an over-the-range model, you’ll need to measure for an over-the-range microwave specifically. These types typically require more specific measurements to accommodate both the microwave and the range below, including necessary ventilation space between the microwave.

Start by measuring the width where the microwave will go. For over-the-range models, this measurement should match the standard width of the range for a seamless fit. Next, measure the height and the depth, keeping in mind that open-door depths range from roughly 200 mm and up, which affects how far the open microwave door will stick out. It’s also essential to consider the space from the bottom of the microwave to the range below to ensure compliance with safety and functionality standards.

Always keep an eye on the sale price excluding taxes and any discounts taken off regular prices, especially if these offers are valid for new orders only and while supplies last. Whether you’re installing the microwave in a cabinet or under a counter, these measurements will help ensure that you choose the right size and get the best fit for your kitchen layout. Remember, accurate measurement is key to making sure your new appliance fits perfectly and works efficiently in your available space.

Understanding Standard Microwave Sizes

When you’re shopping for a new microwave or planning to replace an old one, it’s crucial to understand standard microwave sizes to ensure it fits your space perfectly. Here’s a quick guide to help you measure your microwave accurately.

Measuring Basics

The first step in choosing the right microwave is to measure the width, height, and depth of the area where it will be installed. For standard models, particularly those that will be installed in a cabinet, it’s important to check the standard cabinet width which usually aligns with microwave sizes. When measuring the width, make sure to allow for a little extra space on each side for ventilation. Typically, microwaves come in widths ranging from 20 inches to roughly 30 inches.

Over-the-Range and Built-In Microwaves

Installing an over-the-range microwave or a built-in unit requires a bit more precision. You need to measure the space from the microwave to the top of the range below and ensure there is adequate ventilation space. Over-the-range microwave dimensions are critical because they need to align with the range below and the standard ventilation setup. For built-in models, it’s also crucial to measure the closed-door depths, which usually start from roughly 200 mm, and ensure there’s enough room for the door to open since you’ll need access during use.

Special Considerations

When dealing with over-the-range and built-in microwaves, you might also consider additional components like microwaves and hoods or a trim kit, which are used to ensure a seamless fit and finish. Ensure that these additions can be installed with your chosen model and that the regular price excluding taxes fits within your budget. Keep in mind, certain promotional offers, like discounts ending on specific dates (e.g., “ends May 15”), cannot be combined with other discounts.


As we wrap up this comprehensive guide on measuring microwave sizes, remember that finding the perfect microwave involves more than just fitting it into an existing microwave enclosure or cabinet width. Whether you’re installing the microwave above your stove or anywhere in your kitchen, the size, type, and placement are crucial to ensuring efficiency and ease of use.

For over-the-range microwaves, typical exterior dimensions range from 16 to 20 inches in height, with widths around 24 inches to match standard cabinet dimensions, ensuring a seamless fit. The door depths, important for ensuring you have enough clearance, usually range from 150 mm with the door closed to 300 mm with it open. This is vital for maintaining usability without obstructing kitchen flow.

Compact over-the-range microwaves, which are ideal for smaller spaces, usually have exterior dimensions that fit snugly above the stove, providing powerful functionality without overwhelming the space. These models typically offer interior capacities that range from 0.8 to 2.1 cubic feet for full-sized models, catering to different cooking needs from quick recipes to more elaborate dishes.

With this knowledge, you’re well-equipped to measure, choose, and install a microwave that fits not only the physical space in your kitchen but also enhances your cooking experience. From kitchen hacks to quick recipes, discover how the right microwave can revolutionize your approach to everyday cooking.
