The awkward laundry question

Can I wash a king-size duvet in an 8kg machine?

Maybe — but 8kg is a borderline answer for many king-size duvets.

Borderline — check carefully

Do not force it

A king-size duvet may fit in an 8kg machine if it is lightweight and the care label allows machine washing. Thick, high-tog or feather/down duvets usually need more room.

When dry, the duvet should not fill the drum tightly. If it cannot move freely, use a 10kg+ machine or a laundrette.
