Which one fits you
On wrists narrower than about 49mm, the Samsung Galaxy Watch FE - Bluetooth · 40mm is the safer pick — it stays proportionate down to roughly 43mm, 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 Samsung Galaxy Watch FE - Bluetooth · 40mm (40.2mm vs 39.3mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Samsung Galaxy Watch FE - Bluetooth · 40mm is the slimmer of the two (9.8mm vs 10.45mm), so it slides under a cuff more easily.
The Amazfit Bip 6 is middle-of-the-pack for thickness among the 530 40mm watches in the database.
Among the 405 39mm watches we hold thickness for, the Samsung Galaxy Watch FE - Bluetooth · 40mm is thinner than 73%, so it wears flatter than its width suggests.
The Amazfit Bip 6 is 0.9mm wider, 5.9mm longer, 0.6mm thicker and 1.3g heavier than the Samsung Galaxy Watch FE - Bluetooth · 40mm.

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 46.3mm · Lug-to-lug 46.3mm · Thickness 10.4mm · 28g
Balanced Fit
46.3mm 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 46.3mm, 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.
