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 LTE 40mm is the thinnest of smartwatches 40mm across and the Galaxy Watch8 LTE 44mm is thinner than 97% of those 44mm across — so both wear flatter than their widths suggest.

The Galaxy Watch8 LTE 44mm is 3.3mm wider, 3.3mm longer and 4g heavier than the Galaxy Watch8 LTE 40mm.
