The fact that the screen of the Apple Watch 40mm and 44mm is larger than the Apple Watch 38mm and 42mm doesn't mean that the watch case is also larger compared to the Series 3 Apple Watch models. so you can also use the Apple Watch 38mm straps on the Apple Watch 40mm. The Apple Watch 42mm straps can also be used on the Apple Watch 44mm.
