Mini Fridge Size, Dimensions & Capacity

Thinking about buying a mini fridge but not sure what size you need? You’re not alone. From compact countertop models to spacious undercounter designs, mini fridges come in all shapes and sizes – and choosing the right size mini fridge is just as important as choosing the right brand or colour.

We’ve got you covered. Here’s everything you need to know about mini fridge measurements, space requirements, and which type will suit your setup best.

 

What Is the Average Size of a Mini Fridge?

Most mini fridges range from 45 cm to 85 cm in height, depending on the design and capacity. On average, you’ll find mini fridge models between 45 to 60 cm wide and 45 to 65 cm deep.

If you’re looking for a standard freestanding mini fridge, the measurements are usually around 55-65cm height x 45-55cm width x 50-60cm depth, with anything from 30 litres to 50 litres capacity.

There is no ‘average size’ of mini fridges, as measurements can vary significantly depending on the type.

 

Mini Fridge Size Options

Mini fridges come in a wide range of shapes and sizes, from compact countertop units to full undercounter models. Here are some of the most common mini wine fridge options and their typical measurements:

 

Countertop Mini Fridges (Smallest Mini Fridge)

Countertop mini fridges are the smallest mini fridges you can buy. They are designed to sit neatly on a desk, shelf, or countertop. This option is perfect for dorm rooms, bedrooms, offices – any place where you want quick access to cans, snacks or even skincare products.

Typical dimensions:

• Height: 25–50 cm
• Width: 25–45 cm
• Depth: 25–45 cm
• Capacity: 6–20 litres

 

What they hold:

Up to around 10 to 15 standard drink cans, or 2–3 small bottles.

 

Compact Freestanding Mini Fridges

Freestanding mini fridges are slightly larger but still lightweight and portable. They’re great for storing drinks, lunch items, and small groceries – perfect for offices, studios, or garden bars.

Typical dimensions:

• Height: 55–65 cm
• Width: 45–55 cm
• Depth: 45–60 cm
• Capacity: 30–50 litres

 

What they hold:

Around 20 to 30 bottles or up to 45 standard cans.

 

Undercounter Mini Fridges

Undercounter mini fridges can fit nicely under your kitchen counter. They're a little taller than freestanding models, and are a great choice for everyday use or as a secondary fridge for drinks and snacks.

Typical dimensions:

• Height: 80–85 cm (standard undercounter height)
• Width: 50–60 cm
• Depth: 55–60 cm
• Capacity: 90–130 litres

Many undercounter wine fridges share these dimensions too.

 

What they hold:

Depending on the layout, around 60–100 cans or 30 to 40 bottles (depending on the bottle size)

 

Beer Fridges and Drinks Coolers

Beer fridges are built specifically for storing bottles and cans at the ideal temperature. They often feature glass doors, LED lighting, and removable shelving for flexible storage.

Typical dimensions:

• Height: 50–85 cm
• Width: 45–60 cm
• Depth: 45–60 cm
• Capacity: 40–120 litres

 

What they hold:

Roughly 40–100 cans depending on layout and shelving style.

 

Tall Compact Fridges (Large Mini Fridges)

Sometimes called “small refrigerators” or “tall mini fridges”, these are the biggest in the mini fridge category. They’re not quite full-sized fridges but offer just enough space for groceries, drinks, and leftovers.

Typical dimensions:

• Height: 85–120 cm
• Width: 50–60 cm
• Depth: 55–65 cm
• Capacity: 120–150 litres

 

What they hold:

Enough for a couple or small household – almost equivalent to half a full-size fridge.

Mini Fridge vs Regular Fridge

A standard full-size fridge can measure up to 180 cm in height and 90 cm in width, while a mini fridge offers a much smaller footprint. This makes mini fridges perfect for small apartments, offices, bedrooms, or even garden bars.

You’ll typically trade freezer space and internal shelving for compactness – but the best mini fridges make up for this with energy efficiency and sleek design.

 

 

How to Measure Your Space for a Mini Fridge

Before you order or install your mini fridge, you need to measure the space properly – not just to make sure it fits, but to ensure there is sufficient space for ventilation.

A few extra minutes with a tape measure can save you the hassle of poor ventilation, doors that won’t open, or a fridge that simply doesn’t fit under your counter.

Here’s a step-by-step guide on how to get accurate measurements and choose the right size mini fridge for your space:

 

Step 1 – Measure the Available Space

Start by measuring the height, width, and depth of the area where you plan to place your mini fridge. Make a note of the maximum dimensions that the fridge can be. This gives you flexibility when comparing different mini fridge models later.

Tip: If you’re planning to install your mini fridge under a counter, measure from the floor to the underside of the worktop (usually around 85 cm for standard counters).

For example, if your undercounter space measures 82 cm high × 58 cm wide × 58 cm deep, you’ll want a fridge slightly smaller (around 80 × 55 × 55 cm). This gives space for airflow and wire clearance.

 

Step 2 – Allow Added Space for Ventilation

Mini fridges need enough space around the rear and sides to release heat generated by the compressor. Without proper airflow, the fridge has to work harder to stay cool, which increases energy use and wear over time. Check out our guide on how much energy mini fridges use for more information.

As a general rule, leave at least 5–10 cm (2–4 inches) of space behind and to the sides.

For built-in or undercounter models, check the manufacturer’s ventilation requirements, as some need even more space. Never place the back of the fridge directly against a wall.

 

Step 3 – Check Door Swing and Handle Space

Make sure the door can open fully without any obstructions such as walls, cupboards, or appliances, allowing at least 5–7 cm of space on the handle side.

If your fridge is going next to a corner or within cabinetry, consider whether the door is reversible – many mini fridges let you change the hinge side. For example, if the fridge will be installed next to a wall on the right, you’ll likely want a left-hinged door that opens toward the centre of the room.

 

Step 4 – Consider Plug and Cable Space

Most mini fridges use a standard UK plug, but you’ll need a bit of space for the cable and plug head behind the appliance. Allow an extra 2–3 cm at the back, and avoid placing the fridge too far from the socket, as using long extension leads can be unsafe.

 

Step 5 – Consider Your Flooring and Weight

Finally, you need to consider how heavy your mini fridge and whether your floor can handle the weight. You also need to make sure the surface is flat. Mini fridges may be light, but they still need a level, stable surface. If your floor is uneven, the door might not close properly and the compressor could vibrate noisily. You can use the adjustable feet (if included) to level it.

Note – Avoid placing your mini fridge directly on carpet as this can block airflow and trap heat.

What Size Mini Fridge is Best for Me?

The right mini fridge for you depends on how you plan on using it. For example, if it’s for storing beer, a drinks cooler might be the best choice for you – but if you want a small fridge for bedroom snacks, then a countertop mini fridge should suffice. Here’s a helpful guide:
