According to Apple’s official sizing guidelines, wrists between 130 and 200mm can wear the 40mm model, while wrists between 140 and 220mm can wear the 44mm model. You are free to select whichever model you prefer as long as you are not at the extremes of the supported sizes.
We can’t tell you which one would look better on your wrist without seeing it, but unless you absolutely must have the larger model, it’s best to use common sense.
While the 40mm is not a good choice if your wrist is close to 200mm, the 44mm will likely seem too bulky on a small wrist. It might be wiser to spend more money to purchase the bigger Apple Watch SE. In relation to money.
