Buying a microwave: how to choose the right model for your kitchen

A microwave may seem like a simple appliance, but small differences in size, power and controls can make a big difference to how easy it is to use every day. A model that looks spacious enough on paper, for example, may not fit a large bowl or square dish. A grill function may also be unnecessary if you mainly use your microwave to heat up meals.

Watch out for these common pitfalls:

  • Looking only at the capacity in litres: capacity doesn’t always tell you how much usable space there is on the base. A turntable, low interior or narrow door can limit the dishes you can use.
  • Confusing microwave power with total power consumption: a microwave rated at 800 watts usually refers to its microwave output. Its power consumption may be higher. On a grill or combination model, energy use varies by function.
  • Assuming extra programmes are essential: automatic menus are useful, but not everyone uses them. For heating and defrosting, a simple microwave-only model with dial controls may be enough.
  • Forgetting about ventilation: don’t place a compact microwave right up against a wall or underneath a shelf if the manual specifies that it needs clearance.

Which specifications matter?

1. Capacity and external dimensions

A 20-litre microwave is a practical size for students, smaller households and flats. As well as checking the capacity, look at the internal dimensions and turntable diameter. A 25 cm plate, for example, won’t necessarily fit in every compact microwave.

Measure the following in advance:

  • the available width, depth and height;
  • the clearance needed for ventilation;
  • the distance from wall units and side walls;
  • the space needed to open the door;
  • the dimensions of your most-used plates and dishes.

A compact microwave isn’t always shallow. Check the stated external dimensions rather than relying on the product title alone. Place a freestanding microwave on a stable, heat-resistant surface. Built-in models have additional niche dimensions and installation requirements.

2. Power and use

A 700-watt microwave is suitable for everyday reheating and simple cooking, but some dishes may take longer. Heating is generally quicker with 800 watts or 900 watts, as long as you adjust the cooking time to suit the dish.

More important than a high wattage alone are:

  • several power levels;
  • a clear timer;
  • a separate defrost function;
  • a quick-start button, if you often heat things for short periods;
  • automatic programmes if you prefer to use pre-set options.

Always follow the manual and the instructions on the packaging. Power levels and cooking times vary from one model to another.

3. Turntable, flatbed or grill

A microwave with a turntable heats food as it rotates. Check whether the turntable can be removed and whether its diameter suits your dishes. A flatbed model has no turntable, so the base stays flat and cleaning may be easier. However, the usable space depends on the shape of the interior.

A microwave with a grill can brown or crisp the top of dishes. This is useful for toast, cheesy dishes or adding a crispy finish. However, a grill doesn’t automatically make the appliance a fully fledged oven. Check which functions are actually included: some models have a microwave and grill, but no fan oven function.

Safe use and care

Only use microwave-safe dishes. Don’t put metal cutlery, aluminium foil or dishes with metallic rims in the cooking cavity, unless the manual specifically allows this for a particular function. Don’t heat sealed packaging or closed containers of liquid. Never run the microwave empty, and stop using it if the door, seal or power cord is damaged.

Clean the interior regularly with a soft, damp cloth. The top of a model with a grill can get particularly hot, so let the appliance cool down before cleaning it. Also check that the ventilation openings remain clear.

Frequently asked questions about microwaves

How many watts do you need for everyday use?

For reheating and defrosting, 700 to 800 watts is often enough. If you want to heat larger portions more quickly, consider a 900-watt model. Always adjust cooking times according to the dish’s instructions and the power level you’ve selected.

Is a microwave with a turntable better than a flatbed model?

It depends on the dishes you use and how you prefer to clean your microwave. A turntable can help distribute heat evenly, while a flatbed model offers a flat base and more flexibility when it comes to the shape of your dishes. For both types, check the actual internal dimensions.

How much does it cost to run a microwave?

Energy use depends on the power, function selected and how long you use it for. A quick heating cycle uses less energy than a longer cooking or grilling session. So don’t just look at the wattage: think about how often you’ll use the appliance and which function you’ll select.
