Which one fits you
Both need much the same wrist — roughly 45–62mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Watch Fit 4 wears larger than the Watch Fit 3 (38mm vs 36.3mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Watch Fit 3 is middle-of-the-pack for thickness among the 126 36mm watches in the database.
Among the 356 38mm watches we hold thickness for, the Watch Fit 4 is thinner than 78%, so it wears flatter than its width suggests.
The Watch Fit 4 is 1.7mm wider, 0.2mm shorter, 0.4mm thinner and 1g heavier than the Watch Fit 3. Both are rectangle.

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 Fit 3
Case 43.2mm · Lug-to-lug 43.2mm · Thickness 9.9mm · 26g
Balanced Fit
43.2mm 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 43.2mm, 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.
