How to Choose the Right Fridge Size for Your Household
Buying a fridge that's too small means constant reorganising and food waste. Too big and you're running an inefficient, mostly-empty appliance. The right fridge size balances your household's storage needs, available space and energy efficiency. Here's exactly how to work it out.
The General Rule of Thumb
A commonly cited guideline is 100–120 litres of fridge capacity per adult in the household, plus 50–60 litres for each child. This assumes weekly shopping and a typical cooking pattern. Here's how that plays out:
| Household size | Recommended capacity | Fridge type |
|---|---|---|
| 1 person | 150–250L | Top/bottom mount, bar fridge |
| 2 people | 250–350L | Top/bottom mount |
| 3–4 people | 350–450L | Top/bottom mount, French door |
| 4–6 people | 450–600L | French door, side-by-side |
| 6+ people | 600L+ | French door, multi-door |
Factors That Increase Fridge Capacity Needs
- Entertaining frequently: Add 50–100 litres for homes that regularly host gatherings
- Bulk buying / warehouse shopping: Costco shoppers and bulk buyers need significantly more capacity
- Large-scale cooking: Meal prepping, marinating large cuts, batch cooking all require more space
- Cultural cooking patterns: Many households from Middle Eastern, South/East Asian and Mediterranean backgrounds prepare and store large quantities of fresh ingredients, marinated proteins and prepared dishes
- No separate freezer: If the fridge's freezer compartment is your primary freezer, allocate accordingly
Measuring Your Space
Before choosing a size, measure the space where the fridge will go. Critical dimensions:
- Width: Standard Australian fridges are 60–90cm wide. French door models are typically 80–90cm wide. Measure the opening and allow 2–3cm clearance on each side for airflow
- Height: Most fridges are 170–190cm tall. Measure to the underside of your overhead cabinets
- Depth: Standard depth is 65–75cm. Counter-depth fridges (60–65cm) sit flush with cabinetry for a built-in look
- Door swing clearance: French door models need space in front for the doors to open fully — typically 120–130cm clearance from the face of the fridge
Fridge Style and Practical Capacity
Nominal litre capacity doesn't always reflect usable storage. Consider the style:
- French door: Wide fridge section at eye level for excellent visibility. Freezer at bottom. Best ergonomics for the fridge section
- Bottom mount: Similar to French door but with a single-door fridge section. Good balance of cost and functionality
- Top mount: Traditional configuration. Economical and energy-efficient. Less ergonomic for fridge section access
- Side-by-side: Equal height fridge and freezer side by side. Wide but requires a wide kitchen opening. Good for households needing equal fridge and freezer capacity
Energy and Running Costs by Size
Larger fridges use more energy, but modern large models are more efficient than older medium models. A current 500L fridge from a major brand might use 350–450 kWh/year. At 30 cents/kWh, that's $105–$135/year to run. An older 350L fridge from 10 years ago might use a similar amount of energy — so upgrading to a larger, newer model often doesn't significantly increase running costs.
