What Size Washing Machine Do I Need? A Simple Guide for Australian Households
Choosing the right size washing machine is more important than most people realise. Too small and you're doing two loads where one would do — wasting water, electricity, and time. Too large and you're running half-empty loads and paying more than you needed to upfront.
This guide will help you pick the right washing machine capacity for your household.
Washing Machine Capacity: What Does It Mean?
Washing machine capacity is measured in kilograms (kg) and refers to how much dry laundry the machine can wash in a single cycle. A 7kg machine handles 7kg of dry clothes, which is roughly one week's laundry for a couple.
Key capacity ranges:
- 5–6kg — Singles and couples, small apartments
- 7–8kg — Small families (2–3 people), regular laundry load
- 9–10kg — Families of 4–5, includes bulky items like towels and bedding
- 11–12kg+ — Large families, frequent laundry, washing bulky items regularly
Recommended Capacity by Household Size
1–2 People (Couple or Single)
A 6–7kg front loader or top loader is ideal. You won't need to wash daily, and a mid-size machine handles everything including a doona wash every few weeks.
Family of 3–4
Go for 8–9kg. This handles school uniforms, sports gear, work clothes, and bedding without needing multiple loads. A front loader at this size is excellent value for energy and water savings.
Family of 5+
A 10–12kg washing machine is worth considering. The larger drum means you can wash a king-size doona, multiple sets of clothing, and towels all in one go. It saves significant time and water over the week.
Front Loader vs Top Loader: Does Size Matter?
Front loaders tend to have a larger usable drum relative to their stated capacity — meaning a 9kg front loader often feels larger than a 9kg top loader. This is because front loaders don't have an agitator taking up space in the middle.
If you're upgrading from a top loader, you may find you can go slightly smaller in capacity with a front loader and still handle the same loads.
Don't Forget Physical Dimensions
Before buying, always measure your laundry space:
- Standard washing machines are 60cm wide and 60cm deep
- Compact machines are available at 45–50cm wide for tight spaces
- Height varies — allow for overhead clearance if under a counter
- Allow 5–10cm behind for hoses and ventilation
Energy and Water Use
Bigger capacity machines use more water and electricity per cycle, but they also mean fewer cycles overall. A family doing 2 loads per day in a 7kg machine might save time and energy by switching to 1 load per day in a 10kg machine.
Look for a machine with a high WELS (water) star rating and high Energy Star rating for long-term savings.
