Which one fits you

On wrists narrower than about 47mm, the Garmin Forerunner 570 42mm is the safer pick — it stays proportionate down to roughly 45mm, where the Google Pixel Watch 3 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Google Pixel Watch 3 45mm gives you more presence.

The Google Pixel Watch 3 45mm wears larger than the Garmin Forerunner 570 42mm (45mm vs 42.4mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.

The Google Pixel Watch 3 45mm is the slimmer of the two (12.3mm vs 12.9mm), so it slides under a cuff more easily.

On the wrist the Google Pixel Watch 3 45mm feels lighter (37g vs 42g, case only).

The Garmin Forerunner 570 42mm is middle-of-the-pack for thickness among the 720 42mm watches in the database.

Among the 385 45mm watches we hold thickness for, the Google Pixel Watch 3 45mm is thinner than 71%, so it wears flatter than its width suggests.

The Google Pixel Watch 3 45mm is 2.6mm wider, 2.6mm longer, 0.6mm thinner and 5g lighter than the Garmin Forerunner 570 42mm. Both are circular.

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

42.4mm on a 55mm wrist

10:09TUE 12lug to lug 42.4mmyour 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 42.4mm, 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.
