Which one fits you

Both need much the same wrist — roughly 49–66mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.

The Amazfit Bip 6 and Xiaomi Redmi Watch 6 share a near-identical 40.2mm case, so wrist presence comes down to thickness, lug-to-lug and weight.

The Xiaomi Redmi Watch 6 is the slimmer of the two (9.9mm vs 10.45mm), so it slides under a cuff more easily.

On the wrist the Amazfit Bip 6 feels lighter (27.9g vs 31g, case only).

The Amazfit Bip 6 is middle-of-the-pack for thickness among the 530 40mm watches in the database.

Among the 539 40mm watches we hold thickness for, the Xiaomi Redmi Watch 6 is thinner than 67%, so it wears flatter than its width suggests.

The Amazfit Bip 6 is 0.2mm wider, 0.2mm shorter, 0.5mm thicker and 3.1g lighter than the Xiaomi Redmi Watch 6. 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

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 46.3mm, 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.
