Dishwashers Sizes Explained

In depth

Dishwashers come in a surprising range of sizes, often confusing shoppers when they're trying to fit one into their kitchen. The labels used by manufacturers and retailers can be particularly misleading, so let’s break down the terminology and help you understand what each size actually means for your household. It’s crucial to get this right before you start measuring up; a dishwasher that won’t fit will lead to frustration, and potentially wasted money.

The primary sizing system used in the UK – and indeed most of Europe – is based on internal dimensions, measured in centimetres. The first key size is ‘Standard’, often labelled as 60cm wide dishwashers. This is by far the most common size found, and represents a good balance between capacity and space efficiency for smaller households or those with slightly tighter kitchen layouts. A standard dishwasher typically accommodates around 12 place settings, making it suitable for single people, couples, or small families. It’s important to note that ‘60cm’ refers solely to the width; you still need to ensure there's adequate depth and height clearance – at least 58cm wide, 54cm deep and 87cm tall are generally recommended to allow for door opening and ventilation.

Moving up in size, you encounter ‘Large’ dishwashers, predominantly around 90cm wide. These offer significantly increased capacity, typically accommodating 16-20 place settings. This is a popular choice for larger families or those who frequently entertain. A 90cm dishwasher demands considerably more space and will likely require a dedicated area in your kitchen – often alongside the cooker – before you can comfortably operate it. Careful consideration must be given to surrounding furniture and work surfaces; they're rarely ideal if placed directly next to an island unit, for example.

Then there’s ‘Super Large’, usually around 120cm wide, capable of holding a truly generous number of dishes - often 24 place settings or more. These are best suited for very large families or those who regularly host large gatherings and require the utmost capacity. A super-large dishwasher needs its own dedicated space, typically in a separate utility room or a larger kitchen area. Installation can also be more complex, requiring specialist plumbing and electrical connections, so factor this into your budget and planning.

A common mistake shoppers make is focusing solely on the advertised width of the dishwasher. Manufacturers often use rounded figures – a 90cm dishwasher might actually measure 88cm or 92cm internally. This can lead to it being too wide for a standard kitchen space. Always double-check the internal dimensions against your available measurements, and allow extra centimetres for comfortable operation and access. Don't just measure the external width; you need the inner measurement where the dishes will actually sit.

Beyond these primary sizes, you’ll occasionally find variations within each category – for example, a 60cm dishwasher might be ‘slimline,’ designed to fit into particularly narrow spaces, or have slightly reduced capacity. Similarly, a 90cm model could have specific features like adjustable racks or folding arms to maximise space utilisation. Always scrutinise the specifications carefully and consider how these features align with your needs.

Finally, remember that floor-to-ceiling height is equally important as width. Dishwashers require clearance around the sides and above for ventilation, which helps to remove excess moisture from the kitchen and prevents mould growth. A minimum of 87cm tall is generally recommended, but check the manufacturer’s specifications for exact requirements, especially if you're planning a compact installation or have low-hanging ceilings. Ignoring this vital dimension can lead to operational issues and potentially damage your appliance.
