Which one fits you
On wrists narrower than about 52mm, the Huawei Watch Fit 4 Pro is the safer pick — it stays proportionate down to roughly 47mm, where the Xiaomi Redmi Watch 5 Active starts to hang over the edge. Above 52mm both sit cleanly, and the Xiaomi Redmi Watch 5 Active gives you more presence.
The Huawei Watch Fit 4 Pro and Xiaomi Redmi Watch 5 Active share a near-identical 40mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Huawei Watch Fit 4 Pro is the slimmer of the two (9.3mm vs 11.4mm), so it slides under a cuff more easily.
On the wrist the Huawei Watch Fit 4 Pro feels lighter (30.4g vs 42.2g, case only).
Among the 539 40mm watches we hold thickness for, the Huawei Watch Fit 4 Pro is thinner than 77%, so it wears flatter than its width suggests.
Among the 509 40mm watches we hold thickness for, the Xiaomi Redmi Watch 5 Active is thicker than 74% — it will sit high even though the case width reads modest.
The Xiaomi Redmi Watch 5 Active is 0.4mm wider, 4.6mm longer, 2.1mm thicker and 11.8g heavier than the Huawei Watch Fit 4 Pro. 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.

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.

Sweet Spot
49.1mm on a 55mm wrist
