Which one fits you
On wrists narrower than about 49mm, the Huawei Watch Fit 4 is the safer pick — it stays proportionate down to roughly 45mm, where the Xiaomi Redmi Watch 3 Active starts to hang over the edge. Above 49mm both sit cleanly, and the Xiaomi Redmi Watch 3 Active gives you more presence.
The Xiaomi Redmi Watch 3 Active wears larger than the Huawei Watch Fit 4 (38.9mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Huawei Watch Fit 4 is the slimmer of the two (9.5mm vs 10.9mm), so it slides under a cuff more easily.
On the wrist the Huawei Watch Fit 4 feels lighter (27g vs 42g, case only).
Among the 356 38mm watches we hold thickness for, the Huawei Watch Fit 4 is thinner than 78%, so it wears flatter than its width suggests.
The Xiaomi Redmi Watch 3 Active is middle-of-the-pack for thickness among the 376 39mm watches in the database.
The Xiaomi Redmi Watch 3 Active is 0.9mm wider, 3.9mm longer, 1.4mm thicker and 15g heavier than the Huawei Watch Fit 4. Both are rectangle.
