The microwave is the appliance most kitchens reach for every single day, yet buying one is easy to get wrong because capacity, power and features vary widely. The right microwave depends on your kitchen size and how you cook. This guide walks through every decision so you end up with one that fits your space and heats your food properly, then point you to the winners in our best microwaves ranking.
Start with size, because it is the most common mistake. Microwaves are measured in cubic feet of interior space, but the external footprint matters just as much in a fitted kitchen. A compact 0.7 to 0.9 cubic foot model suits one or two people and small spaces, while 1.1 to 1.4 cubic feet fits families and larger dishes. Crucially, check the turntable diameter against your actual plates and bowls, since a roomy-sounding microwave can still be too small inside for a dinner plate. Our compact microwave guide covers tight kitchens.
Wattage determines how fast and evenly your food heats. Models range from around 700 watts to 1200 watts. A 700-watt microwave reheats leftovers fine but cooks slowly and less evenly; 900 to 1100 watts is the everyday sweet spot for most people; and 1200 watts, especially with inverter technology, gives the fastest, most even results. Match the power to how much actual cooking, versus simple reheating, you do, and see our guide on what wattage you need.
This is the biggest quality difference. A conventional microwave heats by pulsing full power on and off, which can leave cold centres and rubbery edges, especially when defrosting. An inverter microwave delivers steady, lower power, heating gently and evenly all the way through. If you reheat and defrost often and care about results, an inverter model like the Panasonic is well worth the premium; for occasional basic reheating, a conventional one is fine.
Sensor cooking is one of the genuinely useful smart features: the microwave detects steam or humidity and adjusts the time automatically, so food comes out properly heated rather than over or under done. Beyond that, a handful of clear presets for popcorn, potatoes and reheating save guesswork, while long lists of obscure programs mostly go unused. Prioritise sensor cooking and a few sensible presets over a crowded control panel.
How a microwave operates day to day matters more than people expect. Clear, responsive controls make quick reheating effortless, while cluttered or unresponsive panels frustrate. A mute button, which silences the loud end-of-cycle beeps, is a small feature that makes a surprising difference in a quiet home or open-plan kitchen, especially late at night. If a calm kitchen matters to you, check the model can be muted.
Most people want a countertop microwave, which simply sits on the worktop and is the easiest to buy and replace. Built-in and over-the-range models suit fitted kitchens but cost more and are harder to install. Combination units, like the Breville Combi Wave, add convection baking and even air frying, replacing several appliances in a small kitchen at a higher price. Decide whether you want a simple microwave or a multi-tasker before you shop.
A microwave gets splattered constantly, so a smooth, easy-wipe interior and a removable, dishwasher-safe turntable make daily life easier. Stainless steel looks smart but shows fingerprints, while plain finishes hide marks better. A sturdy door and quality buttons signal a microwave that will last, since flimsy doors and worn keypads are common failure points on the cheapest models. Our guide on cleaning a microwave keeps yours fresh.
Decide on capacity and footprint first, then power, then whether inverter even-heating and sensor cooking matter to you, and finally the type and finish. With those answers you will have a clear shortlist, and our tier-ranked best microwaves of 2026 compares the strongest options so you can buy the one that fits your kitchen and heats your food the way you want.
Compact 0.7-0.9 cu ft suits one or two people; 1.1-1.4 cu ft suits families and larger dishes. Check the turntable fits your plates.
Higher wattage heats faster and more evenly. 900-1100 watts is the everyday sweet spot; 700 watts reheats fine but cooks slowly.
Yes for even heating and gentle defrosting. Inverters deliver steady lower power instead of pulsing, avoiding cold centres and rubbery edges.
