Which one fits you
On wrists narrower than about 45mm, the Garmin Venu® 3S is the safer pick — it stays proportionate down to roughly 43mm, where the Samsung Galaxy Watch8 - LTE · 40mm starts to hang over the edge. Above 45mm both sit cleanly, and the Samsung Galaxy Watch8 - LTE · 40mm gives you more presence.
The Garmin Venu® 3S wears larger than the Samsung Galaxy Watch8 - LTE · 40mm (41mm vs 40.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch8 - LTE · 40mm is the slimmer of the two (8.6mm vs 12mm), so it slides under a cuff more easily.
On the wrist the Garmin Venu® 3S feels lighter (27g vs 30g, case only).
The Garmin Venu® 3S is middle-of-the-pack for thickness among the 375 41mm watches in the database.
Among the 509 40mm watches we hold thickness for, the Samsung Galaxy Watch8 - LTE · 40mm is thinner than 83%, so it wears flatter than its width suggests.
The Garmin Venu® 3S is 0.6mm wider, 1.7mm shorter, 3.4mm thicker and 3g lighter than the Samsung Galaxy Watch8 - LTE · 40mm. 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.
Garmin Venu® 3S
Case 41.0mm · Lug-to-lug 41.0mm · Thickness 12.0mm · 27g
Balanced Fit
41mm 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 41mm, 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.
