Fitbit Watches 40–44mm
9 Fitbit models in the 40–44mm range, actually measuring 40mm to 42mm. The most versatile mid-size range for average wrists.
Thickness is where they separate: 11.2mm to 13.4mm. That 2.2mm gap decides whether a watch slides under a shirt sleeve.
Releases run from 2018 to 2024, so this mixes current models with older references.
Which of these fits your wrist?
Roughly a 14.7cm wrist circumference — the measurement a tape gives you. Compared against lug-to-lug where we have it, case width otherwise.
9 of 9 models sit on this wrist without the lugs hanging over the edge.
