What Does a Microwave Weigh?
The short answer is that most household microwaves weigh between 25 and 60 pounds, or roughly 11 to 27 kilograms. However, that range is wide because microwaves come in many styles and sizes. A compact countertop model might weigh as little as 20 pounds, while a large built-in or commercial unit can exceed 70 pounds. Asking How Much Does a Microwave Weight? is a bit like asking how much a car weighs, because the answer depends on the specific model and configuration.
Several components contribute to a microwave’s weight. The magnetron, which generates the microwaves, is a heavy metal component. The transformer, door assembly, turntable, and outer casing also add significant mass. Larger units with convection features, grilling elements, or stainless steel construction tend to be heavier because they include more metal and additional heating components.
When comparing models, it is important to distinguish between shipping weight and product weight. Shipping weight includes the box, packing materials, manuals, and accessories, and it can be 5 to 15 pounds heavier than the appliance itself. Always check the product weight, sometimes labeled as net weight, when planning installation or lifting.
Why Microwave Weight Matters
Microwave weight matters for several practical reasons. First, it affects installation. A microwave mounted above a stove or built into a cabinet must be supported by brackets, screws, and a structure that can handle the load. If the cabinet or wall is not rated for the appliance’s weight, the unit could fall, causing injury or damage.
Second, weight affects portability. Moving a heavy microwave requires proper technique and sometimes two people. Lifting from the wrong angle can strain your back or damage the appliance’s door alignment. Third, weight influences shipping costs and packaging requirements. Heavier units need sturdier boxes and may incur higher freight charges.
Finally, weight can be an indicator of build quality. Heavier microwaves often contain more metal and fewer lightweight plastics, which can mean better durability and heat retention. However, weight alone does not guarantee quality, so it should be considered alongside other features and reviews.
Microwave Weight by Type
Different microwave types have very different weight profiles. Understanding these categories helps you set realistic expectations before shopping or moving an appliance.
Countertop Microwaves
Countertop models are the most common and generally the lightest. Small units with capacities under 0.8 cubic feet typically weigh 20 to 30 pounds. Mid-size models between 0.9 and 1.2 cubic feet usually weigh 30 to 40 pounds. Large countertop microwaves over 1.3 cubic feet can weigh 40 to 55 pounds. These units rest on a counter and require no mounting, so weight is less of a structural concern, though it still matters for lifting.
Over-the-Range Microwaves
Over-the-range, or OTR, microwaves are designed to be mounted above a cooktop. They include ventilation systems and are typically heavier than countertop models of similar capacity. Most OTR microwaves weigh between 45 and 70 pounds. Their weight requires secure mounting to wall studs and a support bracket, and installation often involves two people.
Built-In Microwaves
Built-in microwaves are installed into cabinetry, often with a trim kit. They can be heavy because they are designed for a flush, integrated look with robust construction. Weights typically range from 40 to 65 pounds. The cabinet opening must be properly sized and reinforced to support the unit safely.
Microwave Drawers
Microwave drawers slide out like a drawer and are installed under a counter or in an island. They are among the heaviest residential microwaves, often weighing 60 to 80 pounds due to their sliding mechanism and heavier construction. Installation requires a dedicated cabinet and careful alignment.
Commercial Microwaves
Commercial units used in restaurants and food service are built for heavy daily use. They often weigh 50 to 100 pounds or more, depending on capacity and power. These units are not typically used in homes but are worth noting for anyone equipping a commercial kitchen.
Microwave Weight by Capacity
Capacity, measured in cubic feet, is one of the strongest predictors of weight. As capacity increases, so does the size of the cavity, turntable, and outer shell. Here is a general guide to expected weights based on capacity.
Compact microwaves under 0.7 cubic feet usually weigh 20 to 30 pounds. Small models between 0.7 and 0.9 cubic feet weigh 25 to 35 pounds. Medium models between 1.0 and 1.2 cubic feet weigh 30 to 45 pounds. Large models between 1.3 and 1.6 cubic feet weigh 40 to 55 pounds. Extra-large models over 1.7 cubic feet can weigh 50 to 70 pounds or more.
Keep in mind that these are averages. A stainless steel model with convection and grill features will weigh more than a basic plastic-front model of the same capacity. Always verify the exact product weight before making decisions based on capacity alone.

| Microwave Drawer | 60-80 | 1.0-1.2 | Under-counter cabinet required |
| Commercial | 50-100+ | 1.0-2.0+ | Heavy-duty surface or mount |
How to Find Your Microwave’s Exact Weight
If you already own a microwave and want to know its exact weight, there are several reliable methods. The most accurate source is the manufacturer’s specification sheet or user manual. Look for a line labeled net weight, product weight, or appliance weight. This figure excludes packaging and reflects the actual unit.
If you no longer have the manual, check the manufacturer’s website. Most brands list detailed specifications for each model, including weight, dimensions, and power consumption. You can also search the model number online, which is usually found on a label inside the door or on the back of the unit.
Retailer product pages are another good source. Major retailers often include weight in the product details section. Be careful to distinguish product weight from shipping weight, as retailers sometimes list both. If only shipping weight is available, subtract roughly 5 to 10 pounds to estimate the actual appliance weight.
For a definitive answer, you can weigh the microwave yourself using a bathroom scale or a shipping scale. This is especially useful for older models or units without clear documentation.
Step-by-Step: How to Weigh a Microwave
If you need to determine the weight of a microwave yourself, follow these steps carefully to get an accurate reading and avoid injury.
- Unplug the microwave and remove all accessories. Take out the turntable, roller ring, and any racks. These small items can add a pound or two and may shift during weighing.
- Clear a sturdy surface. Place a bathroom scale on a hard, flat floor. Avoid carpet, which can cause inaccurate readings.
- Weigh yourself first. Step on the scale and note your weight. This gives you a baseline for the subtraction method.
- Lift the microwave carefully. Bend at the knees, keep your back straight, and hold the unit close to your body. If it is heavy, ask someone to help.
- Step on the scale while holding the microwave. Note the combined weight of you and the appliance.
- Subtract your weight. Subtract your solo weight from the combined weight to get the microwave’s weight.
- Record the result. Write down the weight for future reference, especially if you plan to move or mount the unit.
For very heavy units over 50 pounds, consider using a shipping scale or having a second person assist. Never attempt to lift a heavy microwave alone if you are unsure of your ability to do so safely.
Installation and Mounting Considerations
Weight plays a critical role in installation, particularly for over-the-range and built-in models. Most OTR microwaves require mounting to at least two wall studs using a provided bracket and bolts. The wall must be able to support the unit’s weight plus any additional load from items placed inside.
Before installation, verify that the wall studs are in good condition and spaced appropriately. If studs are not where you need them, you may need to add blocking or use a different mounting method. The cabinet above the microwave also helps support the unit and must be securely attached to the wall.
For countertop models, weight is less of a structural issue, but you should still ensure the counter can support the unit. Laminate or thin surfaces may flex under a heavy microwave. If the unit vibrates during operation, a non-slip mat can help distribute the weight and reduce movement.
Always follow the manufacturer’s installation instructions. They specify the minimum wall and cabinet requirements based on the unit’s weight. Skipping these steps can lead to sagging, loose brackets, or a fallen microwave.
Moving, Shipping, and Transporting a Microwave
Moving a microwave requires more care than many people expect. The glass turntable, door hinges, and internal components can be damaged by bumps and drops. Weight makes the unit awkward to carry, especially if you are moving it alone.
When packing a microwave for a move, remove the turntable and roller ring and pack them separately in bubble wrap. Use the original box if possible, or a sturdy box with at least two inches of padding on all sides. Tape the door shut to prevent it from opening during transit, but do not tape directly on the finish.
For shipping, use the manufacturer’s packaging guidelines or a professional packing service. Heavier units may require freight shipping rather than standard parcel service. Always insure the shipment for the replacement value of the appliance.
When lifting a microwave into a vehicle or onto a shelf, use a dolly or hand truck for heavy units. Keep the unit upright to protect the internal components. Avoid laying it on its side unless the manufacturer specifically allows it.
Tips and Best Practices
Here are practical tips to help you handle microwave weight safely and effectively.
- Check weight before buying. If you plan to mount the unit, verify that your wall and cabinets can support it.
- Use two people for heavy units. Anything over 40 pounds should be lifted by two people whenever possible.
- Keep the unit level. A heavy microwave that is not level can strain the door and affect cooking performance.
- Reinforce weak surfaces. If your counter or shelf flexes, add support or choose a lighter model.
- Protect your back. Bend at the knees and avoid twisting while lifting.
- Measure twice. Before installation, confirm that the unit fits the space and that the mounting hardware is rated for the weight.
- Save the packaging. Keeping the original box makes future moves much easier and safer.
Common Mistakes to Avoid
Many people make avoidable mistakes when dealing with microwave weight. Being aware of these can prevent damage and injury.
- Confusing shipping weight with product weight. This can lead to underestimating the actual load on a shelf or wall.
- Mounting without studs. Drywall anchors alone are usually not sufficient for a heavy OTR microwave.
- Lifting alone. Attempting to lift a 50-pound microwave by yourself risks back injury and dropped appliances.
- Ignoring cabinet reinforcement. Built-in and drawer models need properly reinforced cabinetry.
- Laying the unit on its side. This can damage the magnetron or door alignment unless the manufacturer permits it.
- Forgetting accessories. Removing the turntable before weighing or moving prevents breakage.
