Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 52mm, the Garmin Instinct E 40mm is the safer pick — it stays proportionate down to roughly 42mm, where the Xiaomi Redmi Watch 5 Active starts to hang over the edge. Above 52mm both sit cleanly, and the Xiaomi Redmi Watch 5 Active gives you more presence.
The Garmin Instinct E 40mm and Xiaomi Redmi Watch 5 Active share a near-identical 40mm case, so wrist presence comes down to thickness, lug-to-lug and weight.
The Xiaomi Redmi Watch 5 Active is the slimmer of the two (11.4mm vs 13.6mm), so it slides under a cuff more easily.
The Garmin Instinct E 40mm is thicker than 98% of the 539 40mm watches we hold thickness for, the Xiaomi Redmi Watch 5 Active than 74% — so both sit higher than their widths suggest.
The Xiaomi Redmi Watch 5 Active is 0.4mm wider, 9.1mm longer, 2.2mm thinner and 1.2g heavier than the Garmin Instinct E 40mm.

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.
Measure at the point where you wear your watch — typically just below the wrist bone.
Flat width — lay your arm on a table, palm facing up, and measure straight across the top of your wrist with a ruler. Bone to bone; do not follow the curve down the sides.
Around — wrap a tape measure snugly round the wrist. No tape? Wrap a strip of paper, mark the overlap and hold the strip against a ruler.
Width ≠ circumference. They are different numbers — around 170mm is about 64mm across — so set the toggle to whichever one you actually measured before you type it in.

Balanced Fit
40mm on a 55mm wrist
Across the wrist it works — 7.5mm spare each side — but a tall watch on this wrist. Fine over a sleeve, awkward under one.
On a 55mm wrist the sweet spot is 47–53mm lug to lug. This one is 40mm, so you could go bigger.
Measure where you wear it, just below the wrist bone. Either of these works — the tool converts between them.
- 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. Around — a tape, or a strip of paper marked and held against a ruler, snug the whole way round.
Leather: Attaches at the lugs, so the case back rests on your skin. Thins and softens with wear. Typical figures, not this model’s own.

Sweet Spot
49.1mm on a 55mm wrist
Across the wrist it works — 2.9mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
