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 Xiaomi Redmi Watch 6 starts to hang over the edge. Above 49mm both sit cleanly, and the Xiaomi Redmi Watch 6 gives you more presence.
The Huawei Watch Fit 4 Pro and Xiaomi Redmi Watch 6 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 9.9mm), so it slides under a cuff more easily.
The Huawei Watch Fit 4 Pro is thinner than 77% of the 539 40mm watches we hold thickness for, the Xiaomi Redmi Watch 6 than 67% — so both wear flatter than their widths suggest.
The Huawei Watch Fit 4 Pro is 2mm shorter, 0.6mm thinner and 0.6g lighter than the Xiaomi Redmi Watch 6. Both are rectangle.
