Which one fits you

On wrists narrower than about 49mm, the Garmin Venu 4 45mm is the safer pick — it stays proportionate down to roughly 47mm, where the Amazfit Active Edge starts to hang over the edge. Above 49mm both sit cleanly, and the Amazfit Active Edge gives you more presence.

The Amazfit Active Edge wears larger than the Garmin Venu 4 45mm (46.6mm vs 45mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Amazfit Active Edge is the slimmer of the two (12mm vs 12.5mm), so it slides under a cuff more easily.

On the wrist the Amazfit Active Edge feels lighter (34g vs 38g, case only).

The Amazfit Active Edge is thinner than 69% of the 47mm watches we track and the Garmin Venu 4 45mm than 70% of the 45mm ones — so both wear flatter than their widths suggest.

The Amazfit Active Edge is 1.6mm wider, 1.6mm longer, 0.5mm thinner and 4g lighter than the Garmin Venu 4 45mm. 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

46.6mm on a 55mm wrist

10:09TUE 12lug to lug 46.6mmyour 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 4753mm lug to lug. This one is 46.6mm, 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.
