Which one fits you

On wrists narrower than about 49mm, the Amazfit Cheetah Square is the safer pick — it stays proportionate down to roughly 46mm, 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 Amazfit Cheetah Square and Xiaomi Redmi Watch 3 Active share a near-identical 38.7mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Amazfit Cheetah Square is the slimmer of the two (9.9mm vs 10.9mm), so it slides under a cuff more easily.

On the wrist the Amazfit Cheetah Square feels lighter (37g vs 42g, case only).

Among the 339 39mm watches we hold thickness for, the Amazfit Cheetah Square is thinner than 74%, 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 0.2mm wider, 2.9mm longer, 1mm thicker and 5g heavier than the Amazfit Cheetah Square. Both are rectangle.

Watch Fit Tool

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.

Balanced Fit

44mm on a 55mm wrist

10:09TUE 12lug to lug 44.0mmyour wrist 55.0mm

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 44mm, 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.
