What Size Fridge Do I Need? Fridge Capacity Explained

Where would we be without the humble refrigerator? It’s an appliance we all take for granted, but choosing the right one for your needs can be tricky. Not only are there a multitude of different styles, brands and features to think about, there’s a wide range of sizes on offer too. From compact mini fridges to undercounter versions and gigantic American-style models, there’s a fridge or fridge freezer out there for everyone.

To help you zero in on the perfect fridge, we’ve put together a handy guide to sizing and capacities. Below, we’ll cover the standard fridge freezer sizes you’ll encounter while shopping, explain the different types of fridges available (and how their designs affect their internal and external dimensions) and offer some top tips to help you choose the appliance that’s right for you.

Types of fridge and fridge freezer

Before we take a closer look at sizing, first we need to cover the different types of fridges available. Why? Because each type brings something different to the table, not just in terms of design and features, but also in terms of storage space. Let us explain…

• Freestanding fridges: These models offer the most flexibility in terms of design, as they aren’t built directly into your kitchen units. That means there are no specific space limitations for them to adhere to, and that means freestanding fridges can often be larger than their built-in counterparts.
• Integrated fridges: By contrast, integrated (or built-in) fridges are installed into your kitchen units. They typically feature a single door and are available in both full and half-height forms, the latter being compact enough to fit beneath your worktop. Integrated fridges offer a neat, uncluttered look, but aren’t usually as spacious as the largest freestanding models.
• Tabletop fridges: As the name suggests, these fridges are designed to sit on top of your kitchen counter, not beneath it. Generally speaking, this makes them smaller than most freestanding or integrated fridges – ideal for compact kitchens.

Of course, it’s not just the style of appliance you choose that matters, but the configuration. You can opt for a fridge or a fridge freezer, which combines two appliances into one. Some fridge freezers contain larger fridge compartments with only a small freezer section, while others are split 50:50. Some contain just shelving, while others come with drawers and separate storage compartments.

As you can tell, there’s a lot to consider. That’s why it’s important to identify which type of fridge best suits your needs before even considering size. For instance, if you need a compact, portable fridge, a tabletop version is best. If you want your kitchen to look uncluttered and minimalist, an integrated model is ideal.

Once you’ve decided which type of fridge to go for, you’ll then be able to narrow down your selection by size. Let’s take a closer look at the standard fridge and fridge freezer sizes you’re most likely to encounter.

Standard fridge freezer sizes explained

• Full height fridges: The largest type of refrigerator on the market, full height models are ideal for families and those who love to entertain. Not only do they often come with additional features (like water dispensers), they offer more than 600 litres of storage space in some cases. Even the smallest full height fridges have more than 200 litres of space inside – enough to accommodate all your favourite snacks, drinks and ingredients.
• Under-counter fridges: Half height fridges (otherwise known as under-counter fridges) are significantly shorter in stature, but often every bit as wide and deep as full height models. Expect upwards of 100 litres of storage space in the most spacious under-counter fridges.
• Mini fridges: Offering between 40 and 70 litres of storage space, mini fridges are by far the most compact option available. Although this rules them out for families, they’re ideal for smaller kitchens or for those in need of a little extra storage space. 

What size fridge is right for me?

Now you know what to expect in terms of sizing and capacity, which size of fridge or fridge freezer should you choose? Well, it depends on the size of your household. For one or two people, an undercounter fridge with roughly 100 litres of storage space should suffice – but for families, a larger full height model with upwards of 300 litres of storage space is recommended.
