How to Choose the Right Fridge Size for Your Family

Choosing the right fridge size is more important than most people realise. Too small and you're constantly running out of space; too large and you're paying extra in purchase price and running costs for capacity you don't use. Here's how to get it right.

The General Rule of Thumb

The standard starting point is 100 litres per person in the household, plus 100 litres. So:

• 1 person: approximately 200L
• 2 people: approximately 300L
• 3–4 people: approximately 400–500L
• 5–6 people: approximately 500–600L
• Large families or entertainers: 600L+

This is a rough guide. Your actual needs depend on how often you shop, how much fresh food you store, whether you batch cook, and how often you entertain.

Consider Your Shopping Habits

If you shop weekly or fortnightly, you need more fridge capacity than someone who shops twice a week. Households that buy in bulk (Costco shoppers, large families) generally benefit from more freezer space and total capacity.

Fresh Food vs Frozen Food

Think about the ratio of fresh food to frozen food your household uses. If you rely heavily on frozen meals, a model with a larger freezer compartment may suit you better. French door fridges typically have a larger fridge compartment and smaller freezer. Quad door and side-by-side models offer more equal fridge/freezer ratios.

Fridge Configuration Options

• Top mount: Smaller, more affordable, good for 1–2 people
• Bottom mount: Fridge at eye level, popular for families
• French door: Wide, easy access, good for 3–5 people
• Quad door: Large capacity with divided fridge and freezer sections
• Side-by-side: Wide, full-height access to both compartments

Measuring Your Space

Always measure the cavity before buying. Allow at least 50mm clearance on each side, 50mm at the back and 50mm above for ventilation. Measure the doorway width too — some large French door fridges require tilting to pass through standard doorframes.

Energy Costs and Size

A larger fridge uses more electricity. A 600L fridge with a 3-star rating will cost more to run than a 400L fridge with the same rating. If you don't need the extra space, a correctly-sized smaller fridge is both more economical and better for the environment.
