Which one fits you

Both need much the same wrist — roughly 48–67mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Apple Watch Series 11 GPS + Cellular Aluminium 46mm and Xiaomi Redmi Watch 3 Active share a near-identical 39mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Apple Watch Series 11 GPS + Cellular Aluminium 46mm is the slimmer of the two (9.7mm vs 10.9mm), so it slides under a cuff more easily.

On the wrist the Apple Watch Series 11 GPS + Cellular Aluminium 46mm feels lighter (36.9g vs 42g, case only).

Among the 374 39mm watches we hold thickness for, the Apple Watch Series 11 GPS + Cellular Aluminium 46mm is thinner than 83%, 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 Apple Watch Series 11 GPS + Cellular Aluminium 46mm is 0.1mm wider, 0.9mm shorter, 1.2mm thinner and 5.1g lighter than the Xiaomi Redmi Watch 3 Active. 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

46mm on a 55mm wrist

10:09TUE 12lug to lug 46.0mmyour 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 46mm, 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.
