Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 47mm, the Watch Fit 4 is the safer pick — it stays proportionate down to roughly 45mm, where the Watch Fit 4 Pro starts to hang over the edge. Above 47mm both sit cleanly, and the Watch Fit 4 Pro gives you more presence.
The Watch Fit 4 Pro wears larger than the Watch Fit 4 (40mm vs 38mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
On the wrist the Watch Fit 4 feels lighter (27g vs 30.4g, case only).
The Watch Fit 4 is thinner than 78% of the 38mm watches we track and the Watch Fit 4 Pro than 77% of the 40mm ones — so both wear flatter than their widths suggest.
The Watch Fit 4 Pro is 2mm wider, 1.5mm longer, 0.2mm thinner and 3.4g heavier than the Watch Fit 4. Both are rectangle.
