Choosing the right fridge size is one of the most important decisions in an appliance purchase. Too small and you're constantly juggling food; too large and you're wasting money on purchase price and running costs. Here's the definitive guide for Australian households.
The Standard Sizing Rule
The most widely used starting point for fridge capacity in Australia:
Add 100L per person in the household, plus 100L base capacity.
- 1 person: 100 + 100 = 200L
- 2 people: 200 + 100 = 300L
- 3 people: 300 + 100 = 400L
- 4 people: 400 + 100 = 500L
- 5 people: 500 + 100 = 600L
- 6+ people: 600L+
These are good starting points but need adjustment for your household's specific habits.
Adjust Up If:
- You cook at home most nights (larger fresh food storage needed)
- You shop less frequently (once a week or less)
- You batch cook and meal prep
- You entertain frequently
- You buy in bulk from wholesale stores
- You have dietary requirements that mean more fresh produce
Adjust Down If:
- You eat out frequently
- You shop multiple times per week (can get away with less stored)
- You have a separate chest freezer (reducing required freezer capacity in the fridge)
- Kitchen space is genuinely limited
Measuring Your Kitchen Space
Before choosing a fridge, measure your kitchen cavity carefully:
- Width: Standard cavity is 600mm, 680mm, or 900mm. French door models are typically 900mm wide.
- Height: Allow 50mm above the fridge for air circulation.
- Depth: Standard fridges are 600–700mm deep. Counter-depth models (~600mm) look more integrated.
- Door swing radius: Ensure the door can open fully without hitting a wall or island bench.
Fridge Style and Capacity
Top mount: Most affordable. Efficient use of space. Capacities 300–520L for single-door models.
Bottom mount: Ergonomic (fridge at eye level). Capacities typically 350–600L.
French door: Two narrow fridge doors with bottom freezer drawer. Capacities 500–750L. Best for large families.
Side-by-side: Equal fridge and freezer columns. Fits better in narrower kitchens with two people needing access simultaneously. Capacities 500–750L.
Energy Efficiency by Size
Larger fridges use more energy. A 600L fridge uses approximately 60–70% more electricity than a 300L model. If you're between sizes, choose the smaller option that meets your needs.
