Picking the Right Fridge Size — Why It Matters More Than You Think
One of the most common questions we get at our Wetherill Park showroom is: "What size fridge do I need?" It seems simple, but pick too small and you're constantly juggling food. Pick too large and you're paying for space you don't need and spending more to run it. This guide gives you a clear framework to get it right the first time.
The Quick Answer: Fridge Size by Household
| Household Size | Recommended Fridge Capacity | Typical Price Range |
|---|---|---|
| 1 person | 150–250 litres | $99–$249 |
| 2 people | 250–350 litres | $149–$349 |
| 3–4 people | 350–500 litres | $199–$499 |
| 4–5 people | 450–600 litres | $299–$599 |
| 5+ people | 550+ litres or two fridges | $349+ |
These are guidelines for typical households. You may need to go larger if you batch-cook, buy in bulk, or have kids who eat a lot. Go smaller if you're in a studio, frequently dine out, or prioritise energy efficiency.
Understanding Fridge Measurements
Fridge capacity is measured in litres (L). But the marketing number on the box includes both the fridge and freezer compartments combined. Here's roughly how the split works:
- Standard fridge/freezer: approximately 65–70% fridge, 30–35% freezer
- French door models: fridge on top (larger), freezer drawers on the bottom
- Side-by-side: 50/50 split, but each side is narrower and less flexible
So a 400L fridge/freezer gives you roughly 260–280L of actual fridge space. Keep this in mind when you're comparing models.
Measuring Your Space: The 5 Numbers You Need
Before you buy, measure these five things:
- Height of the cavity — including any overhead cupboards. Add 5cm clearance at the top for ventilation.
- Width of the cavity — most standard fridges are 60–90cm wide. Leave 5cm each side for airflow.
- Depth of the cavity — from the wall to the bench front. Most fridges are 65–75cm deep. The fridge needs to open fully without hitting anything.
- Narrowest doorway/hallway it needs to pass through — delivery teams need to get it into your home. Measure the hallway and any internal doorways.
- Distance from power outlet — the power cord is usually 1.5–1.8m. If your powerpoint is on the opposite wall, you'll need an extension cord.
Fridge Style vs Size: Which Type Is Right for You?
Standard Top-Freezer Fridge (most common)
- Most affordable to buy and run
- Freezer on top (harder to access daily items)
- Good range from 250L to 500L+
- Best for: budget buyers, renters, small households
Bottom-Freezer Fridge
- Fridge at eye level = easier to see and reach food
- Freezer as a drawer at the bottom
- Sizes typically 350–600L
- Best for: families who want ergonomic access to fridge daily
French Door Fridge
- Wide fridge section with two side-by-side doors
- Bottom freezer drawer(s)
- Premium look and large capacity (450L–750L)
- Best for: larger families, open-plan kitchens, entertaining

Side-by-Side Fridge
- Fridge and freezer full-height, side by side
- Great for wide spaces, can fit wide platters
- Each section is narrower than you'd expect for the capacity stated
- Best for: wide kitchens, households needing equal fridge/freezer access

How Much Does Running Cost Matter?
In Sydney, electricity costs roughly 28–35 cents per kWh (AGL/Origin standard rate as of mid-2026). An older 450L fridge might use 400–600 kWh per year — costing $112–$210 annually. A newer energy-efficient model of the same size might use 250–350 kWh — saving $50–$80 per year.
The rule of thumb: if you're buying a fridge for less than $400, running cost savings rarely justify paying significantly more for a newer model. For premium fridges ($800+), energy efficiency becomes more financially meaningful over a 5–10 year lifespan.
Fridge Sizes for Specific Sydney Situations
Small Sydney Apartment or Studio
Sydney apartments (especially in the inner suburbs) often have kitchens built for smaller fridges — sometimes 55–60cm wide only, or low overhead cupboards. For small spaces, we recommend:
- 150–280L capacity
- Under 55cm width
- Under 1.65m tall
Browse our fridges $300 & Under for compact, affordable options.
Large Western Sydney Family Home
Many larger homes in Parramatta, Blacktown, Liverpool and Campbelltown have dedicated laundry rooms or garage space for a second fridge. For large families:
- Primary kitchen fridge: 500–650L+
- Garage second fridge: 300–400L chest freezer or bar fridge
Rental Property or Landlord
If you're buying a fridge for a rental, we recommend 350–450L — big enough to satisfy most tenants without being a large capital outlay. A refurbished unit makes excellent financial sense here.
