Which one fits you
On wrists narrower than about 48mm, the Garmin vívoactive 6 is the safer pick — it stays proportionate down to roughly 44mm, where the Samsung Galaxy Watch8 - LTE · 44mm starts to hang over the edge. Above 48mm both sit cleanly, and the Samsung Galaxy Watch8 - LTE · 44mm gives you more presence.
The Samsung Galaxy Watch8 - LTE · 44mm wears larger than the Garmin vívoactive 6 (43.7mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - LTE · 44mm is the slimmer of the two (8.6mm vs 10.9mm), so it slides under a cuff more easily.
On the wrist the Garmin vívoactive 6 feels lighter (23g vs 34g, case only).
The Garmin vívoactive 6 is thinner than 84% of the 42mm watches we track and the Samsung Galaxy Watch8 - LTE · 44mm than 99% of the 44mm ones — so both wear flatter than their widths suggest.
The Samsung Galaxy Watch8 - LTE · 44mm is 1.5mm wider, 3.8mm longer, 2.3mm thinner and 11g heavier than the Garmin vívoactive 6. 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.

Case 42.2mm · Lug-to-lug 42.2mm · Thickness 10.9mm · 23g
Balanced Fit
42.2mm on a 55mm wrist
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 42.2mm, 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.
