Choosing a microwave oven 20 inches wide can feel more complicated than the measurement suggests. You may be replacing an existing unit, renovating a compact kitchen, or trying to balance countertop space with the room you have available.

This guide offers a straightforward way to narrow the field without turning the process into a technical project. You will find a comparison table designed to help you scan important differences side by side, along with practical buying tips for evaluating fit, usability, reliability, and long-term value. Think of it as a checklist for making a confident decision, whether you are shopping for a new home, an upgrade, or a replacement appliance suited to your household and budget.

Our Top Picks for Microwave Oven 20 Inches Wide Reviews
Finding a microwave oven 20 inches wide should not mean settling for a cramped or difficult setup. This size has become popular with homeowners, renters, and remodelers who want a practical balance between countertop footprint and everyday cooking capacity. In the Top 10 microwave oven 20 inches wide reviewed section, you can expect top-rated picks compared for fit, performance, ease of use, cleaning, reliability, and value, with clear guidance for apartments, compact kitchens, and replacement shopping.
1. Chefman 0.7 Cu. Ft. 700-Watt Countertop Microwave Oven

The Chefman 0.7 Cu. Ft. 700-Watt Countertop Microwave Oven is a welcome answer to the daily scramble of heating lunch while still finishing dinner. Its compact footprint suits a small apartment, office break room, or dorm, while six cooking presets reduce button-pushing for common foods. Express cook is especially handy when you want a fast, no-guess start. It also keeps countertop clutter under control when space is at a premium.
Ten power levels give you more control than a basic on-off microwave, from gentle reheating to fuller cooking jobs. Eco mode can cut standby energy use, and the mute button is a thoughtful touch in a noisy kitchen or household where every beep is likely to draw attention. The child safety lock adds peace of mind around a busy family counter. That keeps reheating from becoming another small daily annoyance.
Operation is straightforward, and the 0.7-cubic-foot capacity is best for individuals, couples, or light portions rather than a large casserole dish. It is a practical fit for anyone seeking preset convenience instead of choosing a larger countertop model. Clean the turntable and cavity regularly, and allow clearance around the vents for dependable everyday performance. The controls are approachable for first-time owners, while the compact format suits a rental.
- Compact footprint suits small kitchens
- Six presets simplify common foods
- Ten power levels provide useful control
- Express cook speeds familiar starts
- Mute button helps in shared spaces
- Child lock supports safer placement
- Modest capacity limits oversized plates and dishes
- 700-watt output is less suited to dense, large meals

2. BLACK+DECKER 0.7 Cu. Ft. Stainless Steel Microwave Oven

The BLACK+DECKER 0.7 Cu. Ft. Stainless Steel Microwave Oven is ideal for renters, apartment dwellers, and office users who want reliable reheating without a bulky countertop appliance. Its 0.7-cubic-foot capacity handles bowls, plates, and single-serve portions, while the stainless steel exterior gives a neutral look that blends easily into a compact kitchen. It is a natural choice for a first apartment or shared break room.
At 700 watts, it is best viewed as a straightforward reheating and quick-cooking solution rather than a substitute for a full-size microwave. The door is easy to access, and the simple control layout should appeal to anyone tired of crowded panels or complicated programming. It also fits the needs of users who value function over decorative extras. That makes it an uncomplicated choice for everyday lunches and quick evening meals.
This model makes sense for a second kitchen, dorm room, or tight breakfast station where space and ease matter more than high-capacity cooking. Regular use should be uncomplicated, though buyers seeking stainless steel should expect fingerprints and should keep the door and control face clean. It is a sensible basic option for everyday meals and snacks. It avoids menu navigation for familiar bowls, mugs, and leftover portions.
- Compact 0.7-cubic-foot size fits tight counters
- 700 watts handle everyday reheating
- Stainless exterior complements many kitchens
- Straightforward controls keep tasks simple
- Suitable for dorms, offices, and rentals
- Good option as a second microwave
- Small cavity restricts larger dinnerware
- Stainless finish can show fingerprints

3. TOSHIBA 1.2 Cu. Ft. 1000-Watt Stainless Steel Microwave Oven

The standout feature of the TOSHIBA 1.2 Cu. Ft. 1000-Watt Stainless Steel Microwave Oven is its roomy 1.2-cubic-foot cavity, which offers noticeably more usable space than a typical compact 0.7-cubic-foot model. That extra room makes it easier to fit a wider plate, a taller mug, or a modest casserole without crowding the turntable. That difference helps when reheating leftovers in square containers or preparing several cups at once.
At 1,000 watts, it also brings stronger cooking performance for reheating, defrosting, and preparing larger portions. The stainless steel shell suits a modern kitchen and contrasts with many small black microwaves. It is a strong candidate for a family that wants countertop convenience but does not need a built-in unit, especially when uneven leftovers are a regular frustration. It offers room to grow without requiring a full kitchen renovation.
The larger capacity is the main reason to choose this Toshiba over a space-saving model, while the 1,000-watt rating supports faster, more versatile everyday use. It should still be measured before purchase to confirm counter depth and ventilation clearance. In return, you gain flexibility for dinnerware and quantities that smaller microwaves handle awkwardly. This balance makes it a practical middle step between a compact reheater and a full-size built-in appliance.
- Roomy 1.2-cubic-foot interior
- 1,000 watts support versatile cooking
- Room for wider plates and taller mugs
- Stainless steel suits modern kitchens
- Useful capacity for couples or families
- Stronger output than compact 700-watt models
- Larger countertop footprint than ultracompact microwaves
- Measured capacity may still be tight for oversized serving dishes

4. TOSHIBA Microwave Oven, 0.9 Cu.Ft, 900W, Black Stainless Steel

Unlike many compact microwaves that force a trade-off between cramped capacity and slow reheating, the TOSHIBA 0.9 Cu. Ft. 900-Watt Black Stainless Microwave Oven offers a balanced 0.9 cubic feet and 900 watts. That middle ground gives it more room and cooking power than a small 0.7-cubic-foot unit without taking up the space of a full-size model. It solves the frustration of a tiny microwave without requiring a full-size replacement.
Its black stainless finish adds a more coordinated appearance than a plain glossy-black microwave, though it will still benefit from regular wiping. This model is well suited to everyday leftovers, beverages, frozen foods, and family portions that need reheating without awkward fitting. The wattage is a useful step up for users who find very compact 700-watt appliances frustratingly slow. It should feel more versatile in many modest kitchen layouts. (See Also:Invertor Microwave)
The result is a practical compromise for apartments, offices, and medium-size kitchens where counter space is limited but a tiny cavity is not desirable. It is easier to recommend as a general-purpose everyday microwave than an ultracompact unit or a large family cooker. Measure the available width, depth, and overhead clearance before installation, and leave adequate space around all required ventilation points to prevent overheating during longer cooking sessions.
- Balanced 0.9-cubic-foot capacity
- 900-watt output handles everyday cooking
- Black stainless finish looks coordinated
- More versatile than tiny 0.7-cubic-foot units
- Suitable for apartments and offices
- Fits between compact and full-size models
- Black stainless surface can show smudges
- Larger than an ultracompact countertop model

5. COMFEE’ 0.7 Cu. Ft. Black Microwave with Eco Mode

Picture coming home at 6:30 p.m. with a bowl of soup that needs heating before everyone sits down. You set the time, start the microwave, and use the waiting time to finish dinner. The COMFEE’ 0.7 Cu. Ft. Black Microwave with Eco Mode is built for this quick routine for one or two portions. It handles a small task that keeps a compact kitchen workable during a busy evening.
At 700 watts and 0.7 cubic feet, it is aimed at everyday reheating, beverages, frozen snacks, and small portions rather than large family dishes. Eco mode is the distinctive extra, helping reduce standby energy use when the microwave is not actively cooking. The black exterior keeps the look simple, and the compact format suits a dorm, office, or first apartment. It is a practical match for daily solo use.
For the person who wants a straightforward countertop unit, the appeal is convenience without a full-size capacity or footprint. It can be especially useful as a second microwave in a busy kitchen, since smaller reheating jobs do not need to interrupt a full-size appliance. Its limits are predictable: modest power and capacity mean larger meals will take more planning. It is best for leftovers, drinks, and reheating standard dinner plates.
- Eco mode supports lower idle energy use
- Compact size fits tight counters
- 700 watts cover common reheating needs
- Black finish suits many kitchen styles
- Useful as a dorm or office microwave
- Simple for everyday one- or two-person meals
- Modest 0.7-cubic-foot capacity limits serving sizes

With 1150 watts of power and a 1.6 cubic foot capacity, it handles everything from full dinner plates to large casserole dishes far faster than lower-wattage compact options, cutting down on wait times during busy mealtimes.

Best Microwave Oven 20 Inches Wide Buying Guide
1. What Is a microwave oven 20 inches wide?
A microwave oven 20 inches wide is defined by its cabinet width, not the usable space inside. It is a compact countertop category that can suit apartments, small kitchens, office break rooms, recreational vehicles, and replacement installations where a full-size unit is impractical. The closest match depends on your routines: one person reheating meals needs less room than a family preparing several dishes at once.
Measure the intended opening before shopping because the stated width is only one part of the installation. Leave the clearance required by the manufacturer, and pay attention to how the door and controls affect access. In my experience, a model that fits the paper dimensions but crowds a backsplash or cabinet can be frustrating every day.
2. Key Features That Actually Matter
Use a shortlist based on the demands of your household rather than chasing specification counts. The following criteria have the greatest effect on whether a microwave oven 20 inches wide works well in daily life.
- For everyday performance, check whether reheating, defrosting, and cooking tasks finish consistently and evenly.
- For build quality and durability, inspect the door, hinges, controls, interior surfaces, and customer feedback for signs of early failure.
- For setup and maintenance, favor clear controls, removable or accessible cleaning parts, and a cavity that can be wiped without awkward disassembly.
- For size, capacity, and fit, verify all exterior dimensions, opening clearance, door swing, ventilation, and the usable cavity size.
- For value at different budgets, compare the functions you will use, warranty coverage, expected support, and likely ownership costs rather than price alone.
- For brand reliability and warranty, review independent durability reports, replacement-part availability, service terms, and the length and scope of coverage.
- For compatibility with an existing setup, match the unit to your available space, electrical arrangement, cooking habits, and preferred level of involvement.
3. How to Choose the Right microwave oven 20 inches wide
Start with usage frequency. Light users may prioritize straightforward operation and easy cleaning, while frequent cooks may need stronger everyday performance and a cavity sized for their usual dishes.
Set a realistic budget before opening the Top 10 list, then include delivery, installation, and repair costs in the comparison. Match each option to the role it will play in your home: compact everyday appliance, flexible family helper, or replacement for a constrained opening. The best choice is not automatically the most expensive or the smallest one; it is the model whose size, capabilities, and support terms align with your expectations. (See Also:Microwave Oven Sams)
4. Common Buyer Mistakes to Avoid
Most beginner mistakes happen before the appliance reaches your kitchen. These checks can prevent poor fit, frustrating operation, and avoidable costs later.
- Ignoring the full installation space can lead to blocked ventilation, a door that will not open, or damage during placement, so measure height, depth, width, and required clearances first.
- Buying on capacity alone can disappoint if dishes do not turn freely or the cavity is inconvenient to access, so bring the sizes of the cookware you use most.
- Overvaluing unfamiliar controls may create a steep learning curve, so test the interface and read the manual before purchasing.
- Ignoring ownership details can undermine an otherwise good purchase, so compare warranty coverage, repair support, replacement-part availability, and expected cleaning effort.
- Trusting the advertised dimensions without checking the manual can cause fit problems, so verify the exact model and all installation requirements.
Most Asked Questions for Microwave Oven 20 Inches Wide Buyers
Is a 20-inch-wide microwave easy for everyday use?
For most users, a 20-inch-wide microwave is straightforward once the controls are learned. Basic reheating and defrosting are easy to manage, while automatic programs can simplify repeated tasks. Choose an interface with labels you can read easily, and check whether your dishes fit inside with enough room to handle them safely.
How do I know a 20-inch microwave will fit my space?
Measure the countertop or cabinet opening from several points, then compare the unit’s exact width, height, and depth with the manual. Allow space for ventilation, door movement, and nearby walls or trim. Also check the electrical connection and confirm that delivery access is wide enough for the appliance.
What should I inspect when comparing build quality?
Look beyond the finish and assess the door hinges, handle, control response, interior coating, and the way parts fit together. Reviews can reveal recurring alignment or door problems that photos may hide. Warranties help, but careful handling and regular cleaning usually protect the appliance better than assuming a premium appearance guarantees long life.
How reliable are compact 20-inch-wide microwave ovens?
Reliability varies by construction, usage, cleaning, and service support, so no width category is automatically dependable. Look for consistent feedback about heating, door hardware, and electronics over time. Keeping the vents clear, avoiding heavy impacts, and following the care instructions can reduce preventable failures. Recurring complaints should be weighed more heavily than isolated reviews.
Is a more expensive 20-inch microwave always better value?
Not necessarily. The strongest value comes from a model that meets your space, cooking, and maintenance needs without paying for functions you rarely use. Compare purchase price with warranty support, expected energy use, repair access, and usable cavity space. A lower-priced option can suit light use, while frequent users may justify spending more for better long-term support.
Will a 20-inch microwave have enough room for my dishes?
Exterior width does not directly indicate usable capacity, so check the stated interior dimensions and the diameter of your largest plates, bowls, or containers. Leave enough room to turn and remove food safely. A compact model suits smaller portions and single-person households, while families should test their typical dishes before committing to a particularly narrow cavity.
Final Verdict
The best microwave oven 20 inches wide is the one that fits the available space, handles your usual meals, and remains easy to use day after day. Use the comparison table to narrow the choices, then weigh performance, durability, cleaning, warranty support, and total value against your household’s needs. Measure the full opening before shopping, test the controls if possible, and read independent feedback for recurring problems. The Top 10 list provides a practical starting point, but the final decision should follow your own cooking habits, space constraints, and budget rather than a single ranking.
