Start by working out how much space you need for fresh food and frozen portions, rather than choosing the largest total capacity. A fridge-freezer handles both in one appliance; a separate freezer is a better choice if frozen storage is your priority and you have room for an extra appliance. If you mainly buy fresh food and shop often, a fridge on its own may be enough.
Who is this choice for?
Households that alternate between fresh food and pre-prepared portions
If you shop for several days at a time and freeze some of your meals, compare the available litres in each compartment. The total capacity alone won’t tell you how much space is set aside for each use.
Households building up a frozen food reserve
If you cook in batches or regularly store food for freezing, check the dedicated capacity, how easy the drawers are to access and the appliance’s annual energy consumption.
Households short on space
To increase storage without taking over your kitchen, compare the dimensions, door opening and interior layout with the space you actually have available.
What sets the appliances apart?
Fridge only
Worth considering if: you mainly buy fresh food to eat over the next few days.
Bear in mind: without a suitable freezer, you won’t have space to store frozen portions.
Fridge-freezer
Worth considering if: you regularly store both fresh food and frozen portions in one appliance.
Bear in mind: the space allocated to the freezer reduces the room available for fresh food, so check the two capacities separately.
Separate freezer
Worth considering if: you already have a suitable fridge and storing frozen portions is your main priority.
Bear in mind: this appliance takes up extra space and runs continuously.

What to check |
What matters to shoppers |
| Fresh and frozen storage |
Compare the litres in each compartment with your usual shopping and portions. Don’t rely on the total capacity alone. |
I keep fresh food for several days and freeze meals too, so I need enough room in both areas. Around 31% of shoppers would make this balance a priority. |
| Frozen food storage |
Check the dedicated capacity, access to the drawers and whether the appliance can keep food at −18 °C. |
When I prepare several meals in advance, I want to store my frozen portions without cramming them in. This would be the priority for around 25% of shoppers. |
| Continuous energy use |
Compare kWh/year for appliances of the same type and with a similar usable capacity. |
I don’t want to run a large capacity all the time if I rarely use it. Around 25% of shoppers would choose a size suited to their needs for this reason. |
| Size and access |
Measure the space and delivery route; check the door clearance and access to the storage compartments. |
In a narrow kitchen, I need to be able to install the appliance and open its doors without difficulty. For around 19% of shoppers, ease of access would come first. |
Mistakes to avoid
-
Looking only at the total capacity
Two fridge-freezers with a similar total capacity may offer different amounts of space for fresh and frozen food. You could find there’s not enough room for your pre-prepared portions, even if the appliance looks spacious.
Make a note of what you keep chilled and what you freeze during a typical week, then compare the stated capacity of each compartment.
-
Choosing the biggest appliance just in case
ADEME points out that fridges and freezers run continuously, and that unnecessary capacity or features can increase energy consumption.
Choose a storage capacity that suits your usual needs and compare the kWh/year of models with a similar usable capacity.
-
Assuming No Frost guarantees safe food storage
No Frost deals with frost build-up; it doesn’t, by itself, determine how food is stored.
Check the temperatures: Anses recommends 0 to 4 °C in the coldest part of the fridge and specifies −18 °C for storing frozen food.
-
Adding a freezer without planning where it will go
Extra storage also requires space, easy access to the compartments and another appliance that runs continuously.
Before choosing a model, measure the delivery route and the space needed to open its door. Also compare its dimensions, noise level and kWh/year.
Brands to compare
Bosch
Worth considering if you’re looking for a freestanding fridge-freezer with separate capacities listed for the fridge and freezer compartments.
- For the KGN39VLCT, Bosch lists 260 l of fridge capacity, 103 l of freezer capacity, 35 dB and a No Frost function.
- This model measures 203 × 60 × 66,5 cm, so check the space available and the delivery route. These specifications do not apply to all Bosch models.
Liebherr
Worth considering if you’re comparing fridge-freezers with separate compartments and storage features that vary by model.
- Liebherr lists a total capacity of 359 l and a noise level of 35 dB for the CNd 5704 Pure NoFrost.
- Check the capacity of each compartment and the dimensions of the model you choose. Claims about the benefits of EasyFresh and DuoCooling come from the manufacturer.
Whirlpool
Worth considering if you want to compare different types of fridges and fridge-freezers, as well as some freezers.
- The range presented by Whirlpool includes appliances in different sizes and capacities, with No Frost on some models.
- Check the capacity and whether No Frost is included on the model you choose, rather than assuming these features are standard across the range.
A freezer for storing portions
This separate freezer is for households that already have a fridge and need more space for frozen portions.

Frequently asked questions
What temperature should a domestic fridge be kept at?
Anses recommends a temperature of 0 to 4 °C in the coldest part of the fridge. Check it, particularly when the appliance is very full or opened frequently.
What temperature should frozen portions be stored at?
Aim for −18 °C when storing frozen food, as recommended by Anses. Freezing does not destroy most germs, so make sure you also follow good hygiene practices when preparing and defrosting food.
Is No Frost essential for preparing meals in advance?
No. No Frost can reduce frost build-up on models that have it, but it doesn’t replace having enough space for your portions, easy-to-access storage and the right storage temperatures.
