Mini Fridge vs Single-Door Fridge: Which Suits a Small Flat?

Mini fridge or single-door fridge in a small apartment? The floor space matters more than we think. Sometimes we focus on how many people live there when choosing a refrigerator. A single-door refrigerator typically has a capacity of 160L-215L and includes a freezer. On the other hand, a mini fridge typically has a capacity of 45L-55L.  

If you have moved to a new place and started living in a 1RK or have a small kitchen, the dilemma of choosing a single-door fridge or a mini fridge is real. Whether you are renting a fridge or buying a used one based on your stay, keep a few things in mind. From the fridge size chart to how much electricity a single-door or mini fridge uses, here’s everything you need to know. 

Mini Fridge vs Single-Door Fridge: The Difference 

A compact mini fridge typically holds 45L-55L. It's about knee height, with a shelf and little or no freezer space. Single-door fridges hold about 160L-215L and are usually about 1.2 metres tall. The fridge has a vegetable box, several shelves, and a freezer compartment.  

Feature	Mini fridge	Single-door fridge
Typical capacity	45-55 litres	160-215 litres
Typical height	About 51 cm	About 1.2 m
Freezer	None, or a small ice box	Built-in freezer
Shelves	Usually one	Several, plus a vegetable box
Best for	Drinks, milk, a day's leftovers	Weekly groceries and home cooking

How Much Capacity Does a Refrigerator Hold? 

A refrigerator’s capacity is what separates a single-door refrigerator from a mini fridge. A single-door fridge holds three to four times as much as a mini refrigerator does. 

1. Mini Fridge Capacity 

A mini refrigerator usually has a capacity of 45L-55L. It generally features a single shelf and a chiller compartment. You can use the space to store milk, curd, water bottles, and fruits. But storing a week's worth of vegetables may be difficult. People often use a mini fridge for skincare and bedrooms; however, people living in a small flat may have no other option. 

2. Single-Door Fridge Capacity

Single-door refrigerators feature around 160L-215L. When choosing one, check whether it has a dedicated freezer. If a fridge states 183L, its 165L of capacity is split between the main compartment and an 18L freezer. A 189L single-door fridge follows the same pattern: 171L of fridge space and 18L of freezer space. 

Types of Single-Door Fridges 

You may see two types of single-door refrigerators – direct-cool and frost-free. In direct-cool fridges, the cooling happens through ice forming on the back wall. That’s why you need to manually defrost. 

On the other hand, frost-free refrigerators for home use electric fans and heating cycles to prevent ice build-up. This way, you do not need to defrost manually. 

Refrigerator Size Chart for Small Apartments 

You can use the following fridge size chart before making a decision about the capacity.

Size class	Capacity	Approx. size (W x D x H)	Suits
Desk or car cooler	About 20 litres	Varies by model	Drinks, skincare
Mini fridge	45-50 litres	48 x 46 x 51 cm	One person who eats out often
Small single door	160-185 litres	53.5 x 61 x 120 cm	One or two people who cook
Larger single door	185-215 litres	56.5 x 71 x 122 cm	Two people who cook daily

Do You Need a Mini Fridge to Save Space? 

Mini fridges can save space, but they don't offer enough room for regular cooking. A mini fridge for home measures about 48 x 46 cm at the base, while a 183L single-door fridge measures about 53.6 x 61 cm. The single-door fridge takes three times as much space as the mini fridge.

The mini fridge stands around 51 cm tall, so it can sit on a counter. Or, you can keep the mini fridge under a desk. If you have a studio apartment or almost no kitchen space, a mini fridge may be your only option. 

Single-Door Fridge vs Mini Fridge: Electricity Usage 

Check the energy-efficiency rating to see whether a mini fridge consumes less electricity than a single-door fridge. Mini fridges usually have low star ratings. You may see listings with 1 star or above for mini fridges. However, single-door refrigerators have ratings up to 5 stars. 

Factor	Mini fridge	Single-door fridge	What to check
Star rating	Rated only against other small fridges	Rated only against fridges of its own size	The annual kWh figure on the energy label, not the stars alone
Compressor	Varies by model	Some models use an inverter compressor that adjusts its speed to cooling demand	Whether the spec sheet lists an inverter compressor
Defrosting	Rental listings call for defrosting at regular intervals	Direct cool models need manual defrosting	Ice on the cooling wall, which cuts efficiency over time
Placement	Often tucked under a desk or inside a cabinet, where airflow is tight	Usually stands in an open floor slot	Free space around the sides, back and vents

Frost-free fridges consume more electricity, but direct-cool fridges have low running costs. Frost-free models might use more electricity; users can avoid the chore of defrosting at regular intervals. 

Does a Mini Fridge have a Freezer? 

Mostly, mini fridges do not have a freezer. Some mini fridges have a small box at the top, while others have no dedicated freezer compartment. Single-door fridges always have a dedicated freezer compartment. Keeping ice cream or frozen food in a mini refrigerator may not be ideal. 

Should You Rent a Mini or Single-Door Fridge? 

Many people choose a mini fridge because they know they will be in a city for a short time. But the problem is reselling it and recovering the upfront cost. In such cases, renting a fridge – a single-door or mini fridge – may be suitable. Rental platforms such as Rentomojo offer mini fridges and single-door fridges on rent. A mini fridge is for carrying and keeping anywhere, and a single-door fridge is suitable for regular cooking. When you rent a fridge, repairs fall on the service provider. Annual maintenance, upgrades, and relocation are usually included in the plans.  

Last-minute Takeaway 

Whether you need a mini fridge or a single-door fridge depends on whether you live alone, how often you cook, and whether you have enough space. If you live alone or with a flatmate, a single-door fridge is generally suitable. Before deciding which one suits your situation, you should check the refrigerator capacity, floor space and height of the appliance, and the kWh mentioned on the label. If your stay is limited to a few months, renting is another option you have.
