Which one fits you
On wrists narrower than about 47mm, the Samsung Galaxy Watch FE Bluetooth 40mm is the safer pick — it stays proportionate down to roughly 43mm, where the Huawei Watch Fit 4 Pro starts to hang over the edge. Above 47mm both sit cleanly, and the Huawei Watch Fit 4 Pro gives you more presence.
The Huawei Watch Fit 4 Pro wears larger than the Samsung Galaxy Watch FE Bluetooth 40mm (40mm vs 39.3mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Huawei Watch Fit 4 Pro is the slimmer of the two (9.3mm vs 9.8mm), so it slides under a cuff more easily.
On the wrist the Samsung Galaxy Watch FE Bluetooth 40mm feels lighter (26.6g vs 30.4g, case only).
The Huawei Watch Fit 4 Pro is thinner than 77% of the 40mm watches we track and the Samsung Galaxy Watch FE Bluetooth 40mm than 73% of the 39mm ones — so both wear flatter than their widths suggest.
The Huawei Watch Fit 4 Pro is 0.7mm wider, 4.1mm longer, 0.5mm thinner and 3.8g 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 44.5mm · Lug-to-lug 44.5mm · Thickness 9.3mm · 30g
Balanced Fit
44.5mm 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 44.5mm, 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.
