Washing Machine Capacity Guide: What kg Size Do You Need?
When shopping for a washing machine, one of the first questions you'll face is: what capacity do I need? The kg rating refers to how much dry laundry the machine can wash in one load. Choosing the right size matters — too small and you'll need multiple loads, too large and you're wasting water and energy.
Washing Machine Sizes Explained
5–6 kg — Singles and Couples
A 5–6kg washing machine suits 1–2 person households. It comfortably handles shirts, underwear, light bedding and everyday clothes. It's compact and uses less water and energy per cycle. Good for apartment living.
Typical load: About 20–25 T-shirts or one set of double bed sheets
7–8 kg — Small Families
A 7–8kg washing machine is the most popular size in Australia. It suits families of 3–4 people comfortably. You can wash a full set of queen sheets in a single load.
Typical load: About 30–35 T-shirts or a queen duvet cover and pillowcases
9–10 kg — Families with Kids
A 9–10kg machine suits larger families with 4–5 people, or households that do a lot of sports gear, towels and bulky items. Great if you prefer fewer, larger loads.
Typical load: About 45–50 T-shirts or a king duvet
11–14 kg — Large Families or Commercial Use
These machines are designed for large families of 6+ or semi-commercial use. They handle king-size duvets, sleeping bags and large curtains in one load.
Typical load: A king duvet or large items that wouldn't fit in smaller drums
Front Loader vs Top Loader: Does Capacity Work the Same Way?
Yes — the kg rating refers to load capacity in both front loaders and top loaders. However, front loaders generally wash more efficiently per kg. A 7kg front loader often cleans better than a 7kg top loader because the drum action is more thorough.
How to Choose the Right Capacity
| Household Size | Recommended Capacity |
|---|---|
| 1 person | 5–6 kg |
| 2 people | 6–7 kg |
| 3–4 people | 7–9 kg |
| 5+ people | 9–12 kg |
| Large family / active household | 12–14 kg |
Don't Overload or Underload
Overfilling a washing machine is one of the most common mistakes. The drum needs space to tumble clothes properly. As a rule, fill the drum to about three-quarters full. Washing a half-load in a large machine wastes water and energy — try to match the load size to the machine's capacity.
