Which one fits you

On wrists narrower than about 50mm, the Amazfit Active 2 is the safer pick — it stays proportionate down to roughly 46mm, where the Garmin Forerunner 965 starts to hang over the edge. Above 50mm both sit cleanly, and the Garmin Forerunner 965 gives you more presence.

The Garmin Forerunner 965 wears larger than the Amazfit Active 2 (47.2mm 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 13.2mm), so it slides under a cuff more easily.

On the wrist the Amazfit Active 2 feels lighter (29.5g vs 53g, case only).

Among the 316 44mm watches we hold thickness for, the Amazfit Active 2 is thinner than 99%, so it wears flatter than its width suggests.

The Garmin Forerunner 965 is middle-of-the-pack for thickness among the 89 47mm watches in the database.

The Garmin Forerunner 965 is 3.3mm wider, 3.3mm longer, 3.3mm thicker and 23.5g heavier than the Amazfit Active 2. Both are circular.

Watch Fit Tool

For sports watches, lug-to-lug (L2L) is what matters most — it decides whether a watch overhangs your wrist. Bulky is fine; overhang is not.

Balanced Fit

43.9mm on a 55mm wrist

10:09TUE 12lug to lug 43.9mmyour wrist 55.0mm

Comfortably inside the edges of your wrist, and it seats and sits low enough to wear without thinking about it.

On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 43.9mm, so you could go bigger.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 1. Flat width — arm flat on a table, palm up. Measure straight across the top of the wrist, bone to bone, ignoring the curve down the sides.
  2. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
