Washing Machine Capacity Guide: What Size Do You Need?

Washing machine drums are measured in kilograms — the weight of dry laundry they're designed to wash in one go. Pick the right capacity and you'll wash more efficiently with fewer loads. Here's a simple guide.

What the kg rating means

It's the maximum dry load, not how heavy the machine is. Bigger isn't always better — running a huge drum half-empty wastes energy, while overstuffing a small one cleans poorly.

What size for your household?

  • 6–7kg: one or two people.
  • 8kg: a small family of three to four — the most popular size.
  • 9–10kg: larger families, or anyone washing bulky bedding often.
  • 11kg+: big households and heavy users.

A few tips

  • Match the size to your typical load, with a little headroom for duvets.
  • Check the spin speed (rpm) too — a faster spin means drier washing and quicker drying.
  • Look at the energy label; an efficient machine pays back over years of use.

Final thoughts

For most Irish families an 8kg machine hits the sweet spot; size up if you regularly wash bedding or have a big household. Browse washing machines online or ask in any of our 60+ stores.
