Which one fits you
On wrists narrower than about 52mm, the Redmi Watch 6 is the safer pick — it stays proportionate down to roughly 49mm, where the Redmi Watch 5 Active starts to hang over the edge. Above 52mm both sit cleanly, and the Redmi Watch 5 Active gives you more presence.
The Redmi Watch 5 Active and Redmi Watch 6 share a near-identical 40.4mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Redmi Watch 6 is the slimmer of the two (9.9mm vs 11.4mm), so it slides under a cuff more easily.
On the wrist the Redmi Watch 6 feels lighter (31g vs 42.2g, case only).
Among the 508 40mm watches we hold thickness for, the Redmi Watch 5 Active is thicker than 74% — it will sit high even though the case width reads modest.
Among the 539 40mm watches we hold thickness for, the Redmi Watch 6 is thinner than 67%, so it wears flatter than its width suggests.
The Redmi Watch 5 Active is 0.4mm wider, 2.6mm longer, 1.5mm thicker and 11.2g heavier than the Redmi Watch 6. Both are rectangle.
