We’re all trying to do more with less, and sometimes that means downsizing or making do with smaller options.
If you’re living in cramped quarters like a studio or granny flat, are a single- or two-person household, or you’re kitting out a camper or RV, petite appliances will help you make the most of your small space.
And a microwave is one kitchen workhorse that definitely earns the space it takes up: it can cook far more than you probably think it can, and can make short work of some kitchen tasks to help you cook faster.

Here are some things to know, things to consider. Plus, we reveal the best microwave brand according to Australians.

When you’re talking small microwaves, there are two measurements to take into account: the external dimensions and the space inside the microwave.
External dimensions
If you’re buying a microwave for an existing nook or to fit into a specific space, such as under a cupboard, the external dimensions will dictate which microwaves you can shortlist. Even a centimetre or two too large will mean you can’t use it.
If you’re not restricted by a built-in microwave niche, you’ll still need to decide just how much bench space you’re willing to sacrifice, so double-check a microwave’s footprint before you decide it’s the one.
And don’t forget to allow space for ventilation: most microwaves need about 10cm space around the sides for ventilation, and 20cm at the top where the vents are usually located.
To subvert an old adage: measure twice, buy once.
Interior dimensions
What’s inside counts just as much as what’s on the outside – but you shouldn’t always believe what you read.
While a microwave might be advertised as having an 18 or 20L capacity, our experts find that those figures might not be exact, so they manually measure each microwave’s cavity themselves, then calculate the actual internal capacity.
There can be a considerable difference between claimed and actual capacity – and when every centimetre counts, it’s important to know exactly how much space you’re working with.
And if you misjudge the internal size of a microwave, you might not be able to fit your crockery or baking dishes inside. It’s okay to take a plate and some cookware into an appliance store to see if they’ll fit!
All of our detailed microwave reviews list external and internal measurements, plus the usable volume, so you can find the right model for your needs.
Crockery size: Will your crockery fit in the small microwave you’re considering? Some will only accommodate a standard-sized dinner plate. (Though a flatbed microwave can often solve this issue.)
Power: A smaller microwave may not have the same grunt as a larger one, so you’ll need to get used to the reduced power and adjust cooking and reheating times accordingly.
Each year, we rank microwave brands, assessing them on their average test scores, reliability, customer satisfaction and how many of their products score the coveted CHOICE expert seal of approval.
The best microwave brand for 2024 was: Panasonic.
Here are the best brands for 2024, along with their CHOICE Best Brand scores:
Panasonic: 78%

We also considered Kmart, LG, Miele, Samsung, Sharp, Smeg and Westinghouse for Best Brand, however these brands didn’t meet our strict eligibility criteria.
Kmart is below average for customer satisfaction while LG and Sharp are below average for reliability. Samsung and Westinghouse have below average test scores while Miele and Smeg didn’t have enough tested models to be eligible.
