BO tightness at sleeves

I’m knitting a hoodie sweater in a 6 month old size and it’s my first ever sweater. I’m just wondering how loose I should try to bind off to complete my first sleeve.

For a picture reference, I am knitting Ruby. Any suggestions would be appreciated :muah:

In general, it really doesn’t matter since you’ll be seaming them, but try to bind off a bit firmly, but not tight, so the stitches won’t stretch will you’re seaming.
