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.

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.

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.

How to Measure

Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.

  1. 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. 2. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
