A king size duvet will normally weigh around 3-4 kg when dry, so in theory an 8, 9 or 10 kg washing machine should be able to cope with them. However, they get very heavy when wet, and can easily break washing machines. Even the best washing machines struggle to cope with king size duvets.
An 8 kg drum can wash a queen or a lightweight size duvet. This is suitable for a medium size family. A 9 kg machine can wash a whole king size duvet and is the best option for large families.
Can I wash a king-size duvet in a 7kg washing machine? Generally, a 7kg washing machine can comfortably wash a duvet for a double bed but not a king-sized bed. Although your duvet might fit after squeezing it into a 7kg drum, it probably won't get a reliable and thorough cleaning.
12kg washing machine – can fit around 60 T-Shirts or a heavy king sized duvet and is suited for a very large sized family.
We put our summer 4.5 tog in the 8kg washer and dryer, but wouldn't put a winter one in it. In a word... no. For a king size duvet you'd need to go up to a 9kg with an extra-large drum.
Machine Washing Duvets
If your washing machine has a capacity of 7 kilos or more, you should be able to machine wash your double duvet at home. If your washing machine has an 8 kilo drum, this will comfortably wash even a heavy (greater than 10 tog) double duvet, and can handle a queen size duvet too.
Can You Wash a King Size Duvet in an 8, 9 or 10 kg Washing Machine? The short answer is no. Home washing machines usually aren't big and powerful enough to cope with king size duvets, even when they have relatively large capacities.
As a general guideline, you'll want a washer with a capacity of at least 6kg to efficiently wash the doona from a single-sized bed. Doubles will need 7kg, Queens 8kg, and Kings 9kg. And for a full-sized set of floor-to-ceiling curtains, you'll want a washer with a capacity of at least 10kg to clean them well.
More specifically to successfully wash a king-sized comforter, you need a washer that has a drum capacity of 5.0 cubic feet or larger. The washer should be a front-loading washer or a top-loading washer without or with a removable center agitator.
Comforters: Instead of lugging your king-size comforter to a laundromat, you can wash it in any washer with a claimed capacity of at least 4.5 cubic feet, according to our tests. It's best washed by itself, for better agitation and rinsing.
A 8 Kg washing machine can wash 8 shirts, 8 jeans, 2 bedsheets, 2 towels, and 1 pillowcase in a single go.
To get the best results possible, queen- or king-sized duvets should be cleaned in an extra-large capacity front-loading washer and dryer. You'll often find these larger machines at the laundromat, although they tend to cost a few dollars more than the average size washer and dryer.
King: 9 tog-911g, 4.5 tog-567g, 2.5 tog-400g, All season 13.5 tog-1478g.
You can fit a fair amount into a 9 or 10 kg washing machine – here is a rough guide: 4 single quilt covers, 4 single mattress sheets, 8 pillowcases. 2 double quilt covers, 2 mattress sheets, 8 pillowcases. King quilt cover, king mattress sheet, 6 pillowcases, single quilt cover, single mattress sheet.

As a rough guide most 7kg capacity machines will cope with a 10-tog double. But check with the machine's manufacturer first if you are in any doubt. Use about one third of the usual amount of detergent and wash at as high a temperature as the care label allows (above 60°C will kill dust mites).
You'll want to exercise caution when using a top load washer, as the agitator can damage the comforter if it's not durable enough. (Our Berkshire Lite Luxe Comforter is durable enough to withstand the agitation of a top load washer, so long as your washer has a large capacity drum.)
What Capacity Dryer Do I Need For A King Size Comforter? There is a rule of thumb that the chosen dryer must be twice as large as the current washer. As the drying unit requires a large space to dehydrate the water from the thick duvet, you should pick up the machine with more than 3.5 cubic feet.
Many duvets and quilts will recommend taking the item to a professional dry cleaner, but it is possible to wash a duvet at home as long as you have a big enough washing machine and follow the care label instructions carefully.
What Do You Do If Your Comforter Is Too Big For Your Washing Machine? As mentioned before, there are two ways to clean the duvet which does not fit your washer. You can take them to a laundromat and pay for the service. On the other hand, you can wash the bedcover at home by hand with the support of your bathtub.
Most king-size comforters can be washed using your washing machine and dried in a clothes dryer. If your comforter is too large for your machine or if it is made out of delicate materials, hand-wash it and let it air dry instead. Either way, your comforter will be fresh and clean in no time.
The 9kg drum can hold up to 50 items. It could be half a dozen tops, 5 trousers, a couple of bed sheets 5/6 pillow cases and 20 pairs of socks and pants. A really huge capacity for getting your laundry done quickly.
You could have a heavyweight duvet with a low tog, or a lightweight duvet with a high tog, so ensuring that you select the right tog rating is just as important as choosing the right duvet weight. As a rough guide, we recommend a winter duvet tog of 13.5-15, and a summer duvet tog of 4.5-6.
In terms of tog ratings, the cosiest winter duvets range between 10.5 and 15. The 15-tog is fairly heavy-duty in terms of duvets. We'd recommend a 13.5 tog as this should be more than enough to keep you cosy all night long without weighing you down.
