Which one fits you
Both need much the same wrist — roughly 49–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Huawei Watch 4 and Samsung Galaxy Watch8 LTE Classic share a near-identical 46.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
On the wrist the Huawei Watch 4 feels lighter (48g vs 63.5g, case only).
The Huawei Watch 4 is thinner than 86% of the 157 46mm watches we hold thickness for, the Samsung Galaxy Watch8 LTE Classic than 97% — so both wear flatter than their widths suggest.
The Samsung Galaxy Watch8 LTE Classic is 0.2mm wider, 0.2mm longer, 0.3mm thinner and 15.5g heavier than the Huawei Watch 4. 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.
Huawei Watch 4
Case 46.2mm · Lug-to-lug 46.2mm · Thickness 10.9mm · 48g
Balanced Fit
46.2mm 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 46.2mm, 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.
