How to Choose the Right Fridge Size for Your Family
Choosing the wrong size fridge is one of the most common appliance mistakes Australian families make. Too small and you're constantly playing Tetris to fit groceries. Too large and you're paying to cool empty space. This guide, written by the team at Oceania Appliances in Wetherill Park, will help you find the perfect size for your household.
The Simple Rule of Thumb
Allow approximately 100 litres per person in your household as a starting point. So:
- 1 person: ~200–250L (allow slightly more than 100L for practicality)
- 2 people: ~300L
- 3 people: ~380–400L
- 4 people: ~450–480L
- 5 people: ~520–550L
- 6+ people: 570L+
This is a starting point — adjust up or down based on the factors below.
Factors That Mean You Need a LARGER Fridge
- You cook from scratch frequently — Fresh produce, meal prep ingredients, and batch cooking require more fresh food compartment space
- You buy in bulk — Costco shoppers and bulk buyers need extra room to store their haul
- You entertain frequently — Party catering, beverages for guests, and cheese boards all eat up fridge space quickly
- You have teenagers — Teenagers eat a lot. Add at least 50L per teenager over the base calculation
- You have an open plan kitchen — The fridge is on display; a larger, premium model suits the aesthetic
- You rarely shop small top-ups — If you do one big weekly shop rather than small daily shops, you'll have more food in the fridge at once
Factors That Mean You Can Choose a SMALLER Fridge
- You have a chest freezer — If frozen food is stored separately, you don't need a large freezer compartment in your fridge
- You shop frequently (daily/every 2 days) — Less food on hand means less storage needed
- Small kitchen with limited space — Don't sacrifice bench space and walkway width for extra capacity you won't use
- Primary use is drinks and snacks — A second smaller fridge for the main kitchen can complement a primary fridge in the garage
Measuring Your Space Before You Buy
This step is critical and often skipped. Before visiting a store or buying online, measure:
- Width of the fridge cavity — The space between your kitchen cabinets where the fridge will sit. Allow 2–5cm clearance on each side for ventilation.
- Height clearance — Measure from floor to the bottom of your overhead cabinet or top of the opening. The fridge should be at least 2–3cm shorter.
- Depth — Standard fridges are 60–75cm deep. Check if the fridge will stick out past your bench edge. For a flush built-in look, check the cabinet depth.
- Door swing — Will the fridge door open fully without hitting a wall, bench, or adjoining cabinet? A fridge that can't open fully is a daily frustration.
Tip: Bring your measurements to our showroom at Oceania Appliances and we'll help you find models that fit perfectly.
Fridge Types and What Capacity Suits Each
Top Mount Fridge (Freezer on Top)
- Classic design, affordable, easy to maintain
- Best for: Smaller households, secondary spaces, budget-conscious buyers
- Typical range: 250–430L
Bottom Mount Fridge (Freezer at Bottom)
- Australia's most popular style — fresh food at eye level
- Best for: Families who access fresh food daily, modern kitchens
- Typical range: 400–600L
French Door Fridge
- Premium style with wide double-door fresh food compartment
- Best for: Large families, entertainers, modern kitchen aesthetics
- Typical range: 500L–750L+
Side-by-Side Fridge
- Fridge on one side, freezer on the other — equal access to both
- Best for: Homes where fridge and freezer are used equally, narrow door swing spaces
- Typical range: 500L–650L
What About the Freezer Compartment Size?
As a guideline, the freezer should be roughly 20–30% of the total fridge capacity for most households:
- 400L fridge → 80–120L freezer (fine for most families)
- If you freeze a lot — batch cooking, bulk meat purchases, garden produce — consider a separate chest freezer alongside a full-size fridge
Energy Costs — Does Size Matter?
Larger fridges use more electricity. A 500L fridge typically costs $60–$90/year to run; a 300L model might cost $40–$55/year. However, a well-fitted, well-sized fridge runs more efficiently than one you've overpacked trying to squeeze everything in.
