Buying a microwave: how to choose the right model without making an expensive mistake

A microwave may seem easy to choose: compare capacity, power and price, then place your order. Yet many disappointing purchases are caused by details that only become apparent after installation. For example, an appliance may not fit in the kitchen unit, the turntable may be too small for your crockery, or you may find that you hardly ever use the grill function in practice.

As a Joybuy Product Recommendation Officer, I therefore focus mainly on verifiable specifications. When buying a microwave, watch out for these three common pitfalls:

  • Confusing external dimensions with internal capacity: a 20-litre microwave may be compact, but the available height and diameter determine whether your favourite dish will fit inside.
  • Using wattage as the only performance indicator: a 900-watt microwave may heat food faster than a 700- or 800-watt model, but programmes, portion size and the type of dish still matter.
  • Paying for features you will not use: a combination microwave with grill and fan oven functions is more versatile, but takes up more space and often requires more cleaning than a simple freestanding model.

Which specifications are important?

1. Capacity and dimensions

A 20-litre microwave is usually suitable for one person, a student or a small household. Do not just check the number of litres; also look at the diameter of the turntable. A model with a turntable of around 25 to 27 cm is particularly suitable for smaller plates and bowls.

For two people or a family, a 25-litre microwave or larger may be more practical. The larger interior provides more room for oven dishes and bigger portions. Before buying, measure:

  1. The available width, height and depth.
  2. The space around the appliance for ventilation.
  3. The clearance through cupboards, doors and across the worktop.
  4. The diameter of the turntable or the dimensions of the oven cavity.

For a built-in microwave, the cabinet dimensions are especially important. A freestanding model must not simply be placed inside a kitchen unit unless the manufacturer expressly permits this and sufficient ventilation remains available.

2. Power and programmes

Microwave power is measured in watts. Models rated at 700 to 800 watts are generally suitable for reheating, cooking and defrosting. A 900-watt microwave can be useful for larger portions or if you regularly want to prepare food quickly.

Also check the number of power levels. Five or six power levels are useful for everyday tasks. Eleven levels, as found on some compact digital models, provide more intermediate settings for gentle heating or defrosting.

A microwave with a defrost function may work based on time or weight. A weight programme is convenient, but check the food partway through and turn it over if necessary. No automatic programme replaces the instruction manual and a suitable cooking time.

3. Grill, fan oven and materials

A microwave with grill can brown food or give it a crisp topping. The grill uses a heating element and is not the same as an oven function. Only use the supplied rack when this is permitted in the instruction manual.

A microwave with fan oven function combines microwave cooking with circulating hot air. This is useful for pizza, oven dishes and baking, but the appliance is usually larger than a solo microwave. Also check which accessories are included.

The interior lining affects how easy the appliance is to maintain. A microwave with a ceramic interior, such as certain Samsung models, may be easy to clean according to the product description. This is a product specification, not a guarantee that stains or odours will disappear completely. A stainless-steel interior is also practical, but requires careful cleaning without abrasive products.

Safe use and lower running costs

Always use a microwave-safe dish. Metal, aluminium foil and crockery with metallic edges can cause sparks when the instruction manual does not permit their use. Do not heat completely sealed containers or jars. With a grill or combination microwave, check that the supplied rack is used only in the correct setting.

An eco mode can reduce energy consumption in standby, but total usage mainly depends on heating time and the selected function. The grill and fan oven functions generally use more power than microwave cooking alone. Place the appliance on a stable surface, keep the ventilation openings clear and clean the interior regularly.

Frequently asked questions about microwaves

How many watts does a microwave need?

For everyday reheating and defrosting, 700 to 800 watts is often sufficient. If you prepare larger portions or want shorter cooking times, consider a model rated at 900 watts or more. Also compare the capacity and number of power levels.

Is a combination microwave the same as a microwave with grill?

No. A microwave with grill uses a grill element for browning and crisp results. A combination microwave may also have an oven function, often a fan oven. Check which functions are actually listed for each model.

How long does a microwave last?

Its lifespan depends on use, maintenance, ventilation, and the condition of the door and seal. Do not run the appliance empty, avoid abrasive cleaning products and choose a model whose dimensions, power and functions match the way you use it every day.
