How to Choose the Right Fridge Size for Your Household
Choosing the wrong fridge size is one of the most common and costly appliance mistakes. Buy too small and you're constantly running out of space. Buy too big and you're paying for a fridge that's half-empty — and costing more in energy. This guide helps you get it right.
How Fridge Size Is Measured
Fridge size is measured in litres (L), which refers to the total internal volume of both the fridge and freezer compartments combined. A 450L fridge/freezer typically has about 310L of fridge space and 140L of freezer space, though this varies by model.
How Much Fridge Space Do You Need?
As a general rule, Australian fridges should have at least 100L per person in the household, plus an extra 100L for good measure. Here's a quick reference:
| Household Size | Recommended Fridge Size |
|---|---|
| 1 person | 200–300L |
| Couple (2 people) | 300–400L |
| Small family (3–4 people) | 400–500L |
| Large family (5+ people) | 500–700L+ |
Lifestyle Factors That Affect Size
You cook from scratch regularly
If you shop fresh and cook every day, you'll use more fridge space for fresh produce and prepped ingredients. Add an extra 50–100L to the base calculation.
You entertain frequently
Hosting means large platters, big drink quantities and batch-cooked food. If you regularly cook for 6–10+ people, size up to accommodate party-scale food storage.
You shop once a week (or less often)
Weekly shoppers need more fridge storage for a full week's worth of fresh food than people who shop every 2–3 days.
You live in an apartment
Apartment kitchens often have fixed recesses that limit fridge dimensions. Measure the space (width, height AND depth) before buying. Many apartments fit a 350–450L bottom mount fridge comfortably.
Fridge Dimensions: Don't Forget Physical Size
Litre capacity doesn't directly translate to physical dimensions — different models pack storage differently. Always check the physical dimensions of the fridge you're considering and measure:
- The cavity or recess in your kitchen where the fridge will go (width, height, depth)
- The doorways and hallways it will need to pass through on delivery
- Allow 2–5cm clearance on sides and top for ventilation
Energy Considerations by Size
Larger fridges generally use more energy. However, a correctly sized fridge often uses less energy than an oversized one, because modern fridges with fuller refrigerant loads are more efficient. Don't buy a 600L fridge for a 2-person household and expect it to be cheap to run.
