Braided solo loop sizing question

[Orangeman13]

So I have a braided solo loop from my Apple Watch 8 that fits well when I use it on the 8. However, when I put it on my ultra it is tighter - should I size up for braided solo loops?

How tight/uncomfortable is it? The braided loops will stretch over time, so it's up to you.

Also, this doesn‘t make sense. A Solo Loop should feel looser on the Ultra than on a Series Watch (because the Ultra itself is larger).
