Apple watch solo braided loop band sizing

Did you try the sizer tool as well, which size is that recommending? My experience with the braided solo loop is that it is best to go for rather snug fit. Basically at least one size smaller than what the reading comes back with.

I have had mine for half a year now, and it has extended some, that is a factor to count in as well.

However, for sleeping perhaps a lose fitness is preferable. Tough call, you may end up switching them as you go along, at least for the first weeks!

Yes at least for me it was easier to sleep if the band is not that tight, and then during workouts I like them snug. But then, as time goes by, the solo loop will stretch a bit anyway.

Do you have a sports band currently? You could convert and compare the size of that to be extra sure of the right size:
