Samsung Galaxy Watch8 Wi-Fi 40mm vs Galaxy Watch8 Wi-Fi 44mm
Size, specs & wrist fit compared
Which one fits you
Under 14.5 cm (5.7 in) round, the 44mm's lugs overhang and the 40mm's do not; the 40mm fills the wrist at 14–15.5 cm, the 44mm at 15–17 cm.
What else differs
- Screen: the 44mm has the larger screen, 1.47 in across against 1.34 in on the 40mm.
- Battery: about 2 days each in everyday use as rated, though the 44mm carries a 435 mAh cell against 325 mAh in the 40mm.
The Galaxy Watch8 Wi-Fi 40mm is the thinnest of smartwatches 40mm across and the Galaxy Watch8 Wi-Fi 44mm is thinner than 97% of those 44mm across — so both wear flatter than their widths suggest.
The Galaxy Watch8 Wi-Fi 44mm is 3.3mm wider, 3.3mm longer and 4g heavier than the Galaxy Watch8 Wi-Fi 40mm.
