Go one step up if
You shop weekly in bulk
You batch-cook and store meals
You entertain often
Bigger fridges use more power
Short answer: about 150 to 300 litres for one to two people, 300 to 450 litres for three to four, and 450 litres or more for five or more. Shop weekly in bulk or batch-cook? Go one step up.
Litres by household size
| Household | Rough capacity | Notes |
|---|---|---|
| 1 person | 150–250 L | Shop every few days |
| 2 people | 250–300 L | Some batch cooking |
| 3–4 people | 300–450 L | Weekly shop |
| 5+ people | 450 L and above | Large shop, more freezer |
Rough guide only. Check the gross and net capacity on the spec sheet; usable space is lower than the headline litres.

Checks before you buy
- Measure the space, door swing, corridor and lift.
- Compare ticks: fridges carry an NEA energy label, and more ticks means lower electricity use.
- Read the warranty, especially the compressor.

Common questions
How many litres of fridge do I need for 2 people?
About 150 to 300 litres is a common range, depending on how often you shop and cook.
How many litres for a family of 4?
Roughly 300 to 450 litres suits many families of three to four. Go larger if you shop weekly in bulk.
Is a bigger fridge always better?
No. A fridge that is too big wastes electricity cooling empty space. Match it to your household and shopping habits.
How much freezer space do I need?
If you batch-cook or buy frozen food in bulk, look for a bigger freezer or a separate freezer compartment. If not, a standard freezer is enough.
Does a bigger fridge use more power?
Generally yes, but a high-tick model uses less than a low-tick one of the same size. Compare the tick rating and the annual kWh figure.
