Which one fits you
Both need much the same wrist — roughly 43–58mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Samsung Galaxy Watch FE - 40mm and Samsung Galaxy Watch FE - Bluetooth · 40mm share a near-identical 39.3mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
Among the 405 39mm watches we hold thickness for, the Samsung Galaxy Watch FE - 40mm is thinner than 73%, so it wears flatter than its width suggests.
