Which one fits you

Both need much the same wrist — roughly 46–64mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Garmin Venu 3 wears larger than the Amazfit Active 2 (45mm vs 43.9mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Amazfit Active 2 is the slimmer of the two (9.9mm vs 12mm), so it slides under a cuff more easily.

On the wrist the Amazfit Active 2 feels lighter (29.5g vs 47g, case only).

The Amazfit Active 2 is thinner than 99% of the 44mm watches we track and the Garmin Venu 3 than 76% of the 45mm ones — so both wear flatter than their widths suggest.

The Garmin Venu 3 is 1.1mm wider, 1.1mm longer, 2.1mm thicker and 17.5g heavier than the Amazfit Active 2. Both are circular.

For sports watches, Lug-to-Lug (L2L) is what matters most. Bulky is fine — overhang is not.
