FAQ
What does 'Gross Capacity' actually mean when referring to a fridge or freezer?
Gross capacity is the total volume inside the appliance, including all shelves and compartments. It’s measured in litres and represents the maximum amount of food you can store, not necessarily what it will actually hold due to space taken up by the internal design.
How are fridge and freezer sizes typically measured?
Manufacturers usually state capacity in litres – this is the standard measurement for comparing different models. External dimensions like width, height and depth are also essential measurements for ensuring a fit within your kitchen.
What's the difference between ‘Net Capacity’ and ‘Gross Capacity’?
Net capacity refers to the usable space within the fridge or freezer after accounting for the thickness of shelves and compartments. Gross capacity includes the volume of the appliance itself, so you’ll typically find net capacity is smaller than gross capacity.
I have a small kitchen – which size fridge would be best?
For compact kitchens, consider a 130-175 litre fridge; these are often American-style models with narrower footprints. Alternatively, a slimline fridge (around 120 litres) might fit neatly alongside your appliances.
My family is quite large – what size freezer should I be looking at?
For larger families, aim for a freezer with a minimum of 250 litres to comfortably store frozen meals and produce. Consider a chest freezer for maximum capacity or a top-freezer model if space is limited.
How do I measure my available space before buying a new fridge?
Measure the width, height, and depth of the area where you intend to place the appliance, allowing at least 5cm clearance on all sides for ventilation. Don't forget to account for doors opening – they need space to swing freely.
What does ‘American Style’ mean in terms of fridge sizes?
‘American style’ refers to wider refrigerators, typically around 60-80 litres or more, known for their large capacities and features like water dispensers. These models often require a significant amount of space within the kitchen.
I'm buying a combined fridge-freezer – how do I calculate the total capacity?
Simply add together the net capacity of the refrigerator section and the net capacity of the freezer compartment to determine the overall storage volume. Always check both specifications for accurate figures.
Are there any standard dimensions for different types of fridge doors?
Standard door widths are 450mm, 550mm and 600mm. Ensure you measure your doorway or space accurately to guarantee a comfortable fit with the chosen fridge model.
What should I consider when measuring for a chest freezer?
Chest freezers require even more space than top-freezer models, as they need room at the top for the lid to open fully. Allow approximately 90cm height and 80cm width for most standard chest freezers.
In depth
The UK market for fridges and freezers is dominated by a surprisingly complex system of sizing, often leaving consumers bewildered when faced with the plethora of options on display. It’s not just about choosing a model that looks nice; understanding the terminology and knowing what space you actually have available is crucial to ensuring a happy kitchen and efficient food storage. The terms used – Narrow, Wide, Tall, Standard – aren't simply aesthetic descriptions; they represent distinct dimensions that dictate how well a fridge will integrate into your home and, critically, how much usable storage it offers.
The most common descriptor you’ll encounter is ‘Narrow’. This typically refers to refrigerators with a width of between 45cm and 60cm. These models are designed for kitchens where space is at a premium, often found in smaller flats or apartments where maximising the use of hallway or corridor space is key. However, be aware that 'narrow' doesn’t necessarily equate to ‘shallow’. Many narrow refrigerators have considerable internal depths, so double-check the overall dimensions including doors and handles before assuming they will fit. A standard UK kitchen door width is around 83cm, so even a seemingly small refrigerator can encroach significantly on this space if its external dimensions aren't carefully considered.
‘Wide’ refrigerators, conversely, are characterised by a width of 60cm or greater – generally between 60cm and 90cm. These models offer more interior storage volume, making them suitable for families who regularly entertain or require ample space to store larger quantities of food. The extra width also often allows for wider shelves and drawers, which can be particularly beneficial for storing items like turkeys or large platters. It's important to note that a ‘wide’ fridge will naturally take up more floor space; a careful measurement of your kitchen footprint is absolutely essential before committing to one of these models.
‘Tall’ refrigerators are distinguished by their height, typically exceeding 175cm. These appliances are designed for maximizing vertical storage and often feature taller shelves and door compartments. They're a good choice for kitchens with high ceilings or where you want to utilise the full height of a wall. However, they require significant floor space due to their stature, and may necessitate a slightly larger doorway for installation. Consider also that ‘tall’ models can be more difficult to manoeuvre once installed, especially in smaller kitchens.
Then there's the ‘Standard’ refrigerator – generally defined as those between 60cm and 75cm wide, and typically standing around 130-150cm tall. This is often considered a versatile size, capable of accommodating most family needs without overwhelming a typical kitchen space. The 'standard' category represents the most common choice for many UK households and offers a balance between storage capacity and practicality. It’s worth remembering that ‘standard’ can still vary slightly in depth, so always check the total dimensions carefully.
A frequently observed mistake among consumers is focusing solely on the width measurement when assessing fridge suitability. People often measure their kitchen doorway or countertop width without considering the depth of the appliance, including the door handles and any surrounding cabinetry. This can lead to a situation where a ‘standard’ refrigerator – which might seem perfectly sized based on its width – actually doesn't fit through the doorway or sits awkwardly against the wall. Always take accurate measurements of both the available space and the fridge’s external dimensions before making a purchase. Remember, leaving yourself an extra 2-3cm of clearance around the appliance will make installation and maintenance significantly easier in the long run.
Finally, when considering your needs, think about how you use your refrigerator. Do you primarily store fresh produce? Or do you frequently buy frozen foods? The type of food you intend to store will heavily influence the required internal volume. A fridge designed for extensive vegetable storage will likely benefit from a wider drawer or more shelving space than one predominantly used for freezing ready meals. Carefully assess your typical grocery habits and choose a size that aligns with your specific requirements – a slightly larger appliance is generally preferable to one that’s consistently overflowing.
