We do 3-4 loads a week, American top loader. That's work clothes for both of us (office work), plus a 'second shift' of house building, car fixing, shoveling, etc and the associated dirty, smelly clothes for my husband. Plus some of the above for me, especially car fixing (generally not shoveling, as it's not among my skills...). Oh,and our towels and the dogs' bedding get washed every couple of weeks, and our bedding just a little less often. Maybe 3-5 loads is more accurate.
