Here's what it looks like:
DH has to wash his work clothes daily (he has a very physical job and he is a sweater!) and he does those by themselves after he's soaked them first. It's a bit of a pain and we do try to add some stuff to those loads but it doesn't work out as well as it should.
Whites - 1 load a week.
Towels, bathmats and bedding - 3-4 a week. Family of four. Admittedly, we all use bath sheets so that take up space and two bathrooms so two bathmats. Then bedding is two standard single beds but our bed is a king and we have a second double bed duvet on it as well. So basically 4 sets of bedding. We also swim but usually wash swimming towels fortnightly. It all uses up machine space.
Regular colours - about 3 loads of week. DS does a lot of sport but we tend to only wash his school PE kit once or, at most, twice a week. But he also has sports kit from his club which is 2x training per week and matches fortnightly. And irritatingly, in this colder weather, if he then throws on a hoodie, I sometimes have to wash it sooner than I'd like because frankly, it gets stinky. Both children do martial arts too so that's a full set of kit weekly too although usually that's with the whites and I don't always do DD's.
Sometimes it feels like it's the underwear, socks and pyjamas that push it up too. We don't wash skirts, trousers, hoodies that often, but pants, underpants, pyjama pants, vests (me), shirts and t-shirts are all washed after a day's wear.
So our standard is closer to 11 or 12. But there always seems to be something eg, this week, the dog has been sick so I've washed the couch cushion covers, the bathmat (less than a day after I'd replaced it) and the rug in DS' bedroom because she bloody vomited on all of them.
The week before, we had family staying with us, so extra bedding.
With that terrible weather we had a week or two ago, I had to wash extra because me and the DC got caught in the rain while walking the dog and all of us came in absolutely soaked and covered in mud. I was particularly annoyed as I'd taken my jeans out of the laundry that day. Kids was less of an issue - leggings and trackies and extra socks!
