I wash my towels once or twice a week, and bedding every 1-2 weeks, but I have:
Husbands shirts, trousers and extra work fleeces as he's in the warehouse a lot
DS1: 5 x secondary uniform shirts/trousers, 2 x jumpers
2x football kit, 1 x gym kit, 1 x games kit, 1 x swimming kit, 1 x ski layers. It's winter so he wears skins for all outdoor.
DS2:as DS1 but he has Cubs uniform too (we used my jumper to clear the chalk off the floor mum).
I work in healthcare and have to wash my own uniforms - fresh on everyday, as well as the clothes I travel to work in.
Pyjamas are 2-3 days wear, then weekend clothes, going out clothes, delicates, white washes, coats that have got mud splashed up at the back of the,, football boots and wellies all need washing too.
Oh yeah and DS1 does outward bound every other weeks so that more layers, wet coat and waterproofs.
