How Much Does a Microwave Weight? The Complete Guide
Whether you’re looking to buy a new microwave or move your existing one, an important consideration is the weight. Microwaves can vary greatly in weight depending on the size, type, features, and power. But on average, how much does a microwave weigh?
The short answer is that most standard countertop microwaves weigh between 25 and 35 pounds. However, the weight can range from as little as 15 pounds for petite models up to over 100 pounds for extra large commercial units.
In this comprehensive guide, we’ll cover everything you need to know about microwave weights including:
- Average weights for different types of microwaves
- Standard interior and exterior microwave dimensions
- Key factors that determine microwave weight
- Weight ranges for countertop, over-the-range, and commercial models
- How wattage, size, features, and other specs impact weight
Let’s dive in and explore the wide range of microwave sizes and weights.
Average Microwave Weight by Type
Microwave ovens come in three main types: countertop, over-the-range, and commercial. The average weight differs quite a bit for each:
- Countertop microwaves are the most popular and lightweight option designed to sit on a counter or shelf. They typically weigh 25 to 35 pounds.
- Over-the-range microwaves are heavier, weighing 35 to 45 pounds on average. They’re installed above the stove and include ventilation systems.
- Commercial microwaves are the heaviest and largest models meant for restaurants and continual use. They often weigh 70 to 120+ pounds.
Below we’ll take a closer look at the weight ranges for each type of microwave.
Countertop Microwaves
Countertop microwaves are made to sit on a counter, cart, or shelf in your kitchen. They come in a range of sizes with small 0.5 cubic foot models starting around 15 pounds while large 2.0 cubic foot models can weigh 40+ pounds.
The majority of countertop microwaves weigh between 25 and 35 pounds. Compact and portable models with 0.7 to 1.2 cubic feet of capacity tend to fall in the 25 to 30 pound range. While bigger countertop units with 1.5+ cubic feet weigh closer to 35 pounds.
Within the 25 to 35 pound range, expect that:
- Small countertops (0.7 – 1.0 cu ft) weigh 25 to 30 lbs
- Medium countertops (1.1 – 1.4 cu ft) weigh 28 to 33 lbs
- Large countertops (1.5 – 2.0 cu ft) weigh 32 to 37 lbs
Heavier countertop microwaves usually have more features, higher wattage, and larger capacity. We’ll explore how specs impact the weight later on.
Over-the-Range Microwaves
Over-the-range (OTR) microwaves are installed above your stove and include ventilation systems to replace or supplement your existing hood vent.
Since they require more stabilization and have integrated fans and ductwork for ventilation, over-the-range microwaves weigh more than countertops. You can expect most standard over-the-range models to fall in the 35 to 45 pound range.
Some key notes on over-the-range microwave weights:
- Basic OTR models weigh 35 to 40 pounds usually.
- Models with more advanced ventilation features weigh 40+ pounds.
- Low-profile compact OTR microwaves can weigh as little as 30 pounds.
- Large capacity OTR models of 2.0+ cubic feet can weigh up to 50+ pounds.
When installing an over-the-range microwave, make sure you have help lifting it into place above the stove. The installation normally requires two people to safely mount the heavy OTR unit.
Commercial Microwaves
Commercial microwaves are the heaviest type since they’re built for continual restaurant use and high volume cooking. They have rugged construction and more durable components.
While countertop and over-the-range models top out around 50 pounds, commercial microwaves commonly weigh between 70 and 120+ pounds. Extra large capacity industrial models can weigh over 200 pounds!
Some key notes on commercial microwave weights:
- Small commercial models start around 70 pounds.
- Standard large commercial units range from 90 to 120+ pounds.
- Extra capacity jumbo commercial microwaves weigh 140+ pounds.
- Heavy duty stainless steel models weigh more than cheaper commercial units.
The heaviest commercial microwaves require professional installation and reinforcement to handle the weight load. They also usually need a dedicated circuit to handle the high wattage.
Standard Microwave Dimensions
In addition to knowing the weight of your microwave, the physical dimensions are also an important consideration for installation and space planning. Microwave capacity, which influences the weight, is measured in interior cubic feet.
Here are the common interior capacity sizes along with standard exterior dimensions:
| Type | Capacity | Width | Height | Depth |
|---|---|---|---|---|
| Small | 0.5 to 0.9 cu ft | 17 to 19 inches | 10 to 14 inches | 14 to 16 inches |
| Medium | 1.0 to 1.5 cu ft | 19 to 21 inches | 14 to 16 inches | 15 to 17 inches |
| Large | 1.6 to 2.0 cu ft | 21 to 24 inches | 16 to 18 inches | 17 to 19 inches |
Microwaves with larger capacity cubic footage tend to weigh more since they have more interior space and heavier components. Compact 0.7 cubic foot models can weigh just 20 pounds while large 2.0 cubic foot models might weigh 40+ pounds.
Also factor in that:
- Countertop microwaves may be adjustable from 10 to 14 inches high.
- Over-the-range microwaves have standard widths of either 30 or 27 inches.
- Commercial microwaves have widths of up to 60 inches for extra capacity models.
When selecting your microwave, make sure to measure the install location space to ensure the unit fits. Also verify that cabinets, shelves, or walls can support the microwave weight load at that spot.
What Impacts Microwave Weight?
There are several key factors that contribute to the total weight of a microwave oven beyond just the type and size:
Microwave Wattage
Higher wattage equals more weight. Why? Because the magnetron tube that generates the microwaves gets larger as wattage increases. More power means a heavier magnetron tube.
- Small microwaves: 600 to 1,000 watts / 25 to 35 lbs
- Medium microwaves: 1,000 to 1,250 watts / 30 to 40 lbs
- Large microwaves: 1,250 to 1,500 watts / 35 to 45 lbs
More watts also requires a bigger power supply adding weight. The highest wattage residential models can weigh 40+ pounds.
Features and Technology
Models with more features and advanced technology tend to weigh more:
- Inverter tech for continuous cooking: +5 to 8 lbs
- Sensor cooking and reheating: +3 to 5 lbs
- Integrated grill/convection oven: +10 to 15 lbs
- Auto stirrer or turntable: +1 to 2 lbs
While basic microwaves start around 25 pounds, those with multiple high-end features can weigh closer to 40+ pounds.
Capacity and Size
As mentioned earlier, larger capacity microwaves weigh more. A microwave over 2.0 cubic feet can be 10 pounds heavier than a 1.0 cubic foot model. More interior space requires heavier components.
Durability and Build
Commercial models have rugged stainless steel construction and heavier duty parts designed for longevity and continuous use. This adds 20+ pounds over a basic plastic countertop unit.
Cheaper lightweight plastic models will be lighter than high-quality metal construction. But durability and lifespan may suffer.
Typical Microwave Weights by Brand
To give an idea of real-world microwave weights, here are average weights for some top brands and models:
- GE Microwaves: 25 to 40 lbs
- Samsung Microwaves: 25 to 35 lbs
- LG Microwaves: 30 to 40 lbs
- Panasonic Microwaves: 25 to 37 lbs
- Whirlpool Microwaves: 28 to 38 lbs
- Commercial Microwaves: 70 to 140+ lbs
Always check the product specs for a specific model’s weight prior to purchasing. The brand averages above give a good baseline for comparison.
How to Measure and Estimate Weight
If you need to estimate the weight of your existing microwave, here are some tips:
- Weigh yourself on a scale, then hold the microwave and weigh again. Subtract your weight to get the microwave weight.
- Measure dimensions and cross-reference weight charts for that cubic foot capacity.
- Check product label for the model weight specs.
- Google the model # to find official weight online if unsure.
Estimating weight before moving or wall-mounting a microwave helps prevent accidents or damage. If still uncertain, err on the heavy side.
Microwave Weights Can Vary Widely
While standard countertop microwaves fall in the typical 25 to 35 pound range, weights can go much lower or higher depending on the size, features, type, and commercial usage.
On the lightweight end, you have models like the 17-pound Toshiba ML2-EM25PA (0.9 cu ft 1100W) or 15-pound Galanz GSWSA10TA-B910B 0.7 cu ft (700W).
On the heavyweight end, large capacity commercial models like the 120-pound ACP-1060HF (1.8 cu ft, 1100W) or the 200-pound Dacor MWC24 (2.4 cu ft, 1800W) for restaurants and other commercial use weigh considerably more.
With such a wide range, always check specifications and do proper planning when handling, mounting, or moving a microwave. While most standard models for home use weigh under 50 pounds, commercial and specialty models can tip the scales at over 100+ pounds!
The Bottom Line
So in summary, while microwave weights vary widely based on multiple factors:
- The average countertop microwave weight is 25 to 35 pounds.
- Popular over-the-range models weigh 35 to 45 pounds.
- Heavy duty commercial microwaves can weigh 70 pounds or more.
Consider the type, size, features, power, and build materials to get a reasonable weight estimate before purchasing, installing or moving your microwave. And when in doubt, get help lifting and mounting the heavier microwave models.
Now that you know about standard microwave weights and dimensions, you can better choose the right model and plan for safe installation in your home or business. Just be sure to have adequate help, support, and reinforcement in place for mounting heavier commercial and over-the-range units.
