Choosing the right washing machine size is one of the most important decisions when buying a new appliance. Too small, and you’ll be running multiple loads every week. Too large, and you may be wasting energy.
In this guide, we explain what washing machine size you actually need — based on how people in Ireland typically use their machines.
What Does Washing Machine Size Mean?
Washing machine size is measured in kilograms (kg), which refers to the weight of dry laundry the drum can hold.
For example:
-
8kg = suitable for a standard household load
-
10kg = better for larger or bulkier loads
6kg–7kg: Best for Individuals or Small Households
If you live alone or as a couple and don’t do large loads, a smaller machine may be enough.
However, many households in Ireland now skip this size, as the price difference to an 8kg machine is often minimal.
8kg: The Best Choice for Most Homes in Ireland
For most households, an 8kg washing machine offers the best balance between capacity, efficiency and cost.
It’s ideal for:
-
Couples
-
Small families
-
Everyday laundry needs
An 8kg drum can comfortably handle:
-
Clothing
-
Towels
-
Smaller bedding loads
Because of this, 8kg models are the most popular choice and suit the majority of homes.
9kg–10kg: Best for Families or Larger Loads
If you regularly wash:
-
Bedding
-
Towels
-
Larger family loads
A 10kg machine can make a noticeable difference.
With a larger drum, you can:
-
Wash more in one go
-
Reduce the number of cycles per week
-
Save time overall
Why Size Matters in Ireland
In Ireland, drying conditions aren’t always ideal. Choosing the right size (along with a good spin speed) helps reduce drying time and makes laundry more manageable.
A slightly larger machine can also help avoid overloading, which improves washing performance and protects the appliance over time.
Common Mistakes to Avoid
- Choosing too small and needing multiple washes
- Going too large and running half-empty loads
- Not considering bedding and towels when choosing capacity

Final Thoughts
For most homes in Ireland, an 8kg washing machine is the safest and most practical choice. It offers enough capacity for everyday use without unnecessary energy usage.
Larger households may benefit from upgrading to 10kg, especially if you want to reduce the number of washes each week.
