The Garmin Venu 4 - 45mm wears larger than the Garmin Vivoactive 5 (45mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Garmin Vivoactive 5 is the slimmer of the two (11.1mm vs 12mm), so it slides under a cuff more easily.

On the wrist the Garmin Vivoactive 5 feels lighter (36g vs 38g, case only).
