Which one fits you

On wrists narrower than about 49mm, the Garmin Lily 2 Active is the safer pick — it stays proportionate down to roughly 40mm, where the Amazfit Bip 6 starts to hang over the edge. Above 49mm both sit cleanly, and the Amazfit Bip 6 gives you more presence.

The Amazfit Bip 6 wears larger than the Garmin Lily 2 Active (40.2mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Amazfit Bip 6 is the slimmer of the two (10.45mm vs 11mm), so it slides under a cuff more easily.

Both are middle-of-the-pack for thickness among the 40mm and 38mm watches in the database.

The Amazfit Bip 6 is 2.2mm wider, 8.3mm longer, 0.6mm thinner and 1.1g lighter than the Garmin Lily 2 Active.

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

46.3mm on a 55mm wrist

10:09TUE 12lug to lug 46.3mmyour 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 46.3mm, 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.
