Which one fits you
On wrists narrower than about 47mm, the Garmin Vivoactive 5 is the safer pick — it stays proportionate down to roughly 44mm, where the Google Pixel Watch 4 - 45mm starts to hang over the edge. Above 47mm both sit cleanly, and the Google Pixel Watch 4 - 45mm gives you more presence.
The Google Pixel Watch 4 - 45mm wears larger than the Garmin Vivoactive 5 (45mm vs 42.2mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Garmin Vivoactive 5 is the slimmer of the two (11.1mm vs 12.3mm), so it slides under a cuff more easily.
The Garmin Vivoactive 5 is thinner than 82% of the 42mm watches we track and the Google Pixel Watch 4 - 45mm than 70% of the 45mm ones — so both wear flatter than their widths suggest.
The Google Pixel Watch 4 - 45mm is 2.8mm wider, 2.8mm longer, 1.2mm thicker and 0.7g heavier than the Garmin Vivoactive 5. Both are circular.
