Which one fits you
On wrists narrower than about 49mm, the Huawei Watch Fit 4 Pro is the safer pick — it stays proportionate down to roughly 47mm, where the Amazfit Bip 6 starts to hang over the edge. Above 49mm both sit cleanly, and the Amazfit Bip 6 gives you more presence.
The Amazfit Bip 6 and Huawei Watch Fit 4 Pro share a near-identical 40.2mm 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 10.45mm), so it slides under a cuff more easily.
On the wrist the Amazfit Bip 6 feels lighter (27.9g vs 30.4g, case only).
The Amazfit Bip 6 is middle-of-the-pack for thickness among the 529 40mm watches in the database.
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.
The Amazfit Bip 6 is 0.2mm wider, 1.8mm longer, 1.1mm thicker and 2.5g lighter than the Huawei Watch Fit 4 Pro. Both are rectangle.
