Does the Galaxy Watch 4 LTE 44mm fit your wrist?
The 40mm suits wrists of about 13–17.5 cm round; the 44mm, 13.5–19 cm. Both work from 13.5 to 17.5 cm, where it is a choice between more skin either side (the 40mm) and a case that fills the wrist (the 44mm). Under 13.5 cm only the 40mm's lugs stay on the wrist; over 17.5 cm the 40mm starts to look small.
