Garmin Lily 2 Active vs Venu 4 45mm
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 47mm, the Lily 2 Active is the safer pick — it stays proportionate down to roughly 40mm, where the Venu 4 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Venu 4 45mm gives you more presence.
The Venu 4 45mm wears larger than the Lily 2 Active (45mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Lily 2 Active is the slimmer of the two (11mm vs 12.5mm), so it slides under a cuff more easily.
On the wrist the Lily 2 Active feels lighter (29g vs 38g, case only).
The Lily 2 Active is middle-of-the-pack for thickness among the 356 38mm watches in the database.
Among the 385 45mm watches we hold thickness for, the Venu 4 45mm is thinner than 70%, so it wears flatter than its width suggests.
The Venu 4 45mm is 7mm wider, 7mm longer, 1.5mm thicker and 9g heavier than the Lily 2 Active. 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.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Understated
38mm on a 55mm wrist
Well inside your wrist on every measurement — you have room to go a size up if you want more presence.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 38mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 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. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.

45mm on a 55mm wrist
