Garmin Fenix 7S Pro Solar Edition vs Forerunner 165
Size, specs & wrist fit compared

Which one fits you
Both need much the same wrist — roughly 44–61mm across the flat of the wrist. Neither will fit where the other won't, so decide on thickness, weight and features instead.
The Forerunner 165 wears larger than the Fenix 7S Pro Solar Edition (43mm vs 42mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Forerunner 165 is the slimmer of the two (11.6mm vs 14.1mm), so it slides under a cuff more easily.
On the wrist the Forerunner 165 feels lighter (39g vs 63g, case only).
Among the 655 42mm watches we hold thickness for, the Fenix 7S Pro Solar Edition is thicker than 81% — it will sit high even though the case width reads modest.
Among the 318 43mm watches we hold thickness for, the Forerunner 165 is thinner than 86%, so it wears flatter than its width suggests.
The Forerunner 165 is 1mm wider, 1mm longer, 2.5mm thinner and 24g lighter than the Fenix 7S Pro Solar Edition. 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.
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.

Case 42.0mm · Lug-to-lug 42.0mm · Thickness 14.1mm · 63g
Balanced Fit
42mm on a 55mm wrist
Across the wrist it works — 6.5mm 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 42mm, 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.

Case 43.0mm · Lug-to-lug 43.0mm · Thickness 11.6mm · 39g
Balanced Fit
43mm on a 55mm wrist
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 43mm, so you could go bigger.

Frequently Asked Questions
Is the Garmin Fenix 7S Pro Solar Edition bigger than the Garmin Forerunner 165?
The Garmin Forerunner 165 is bigger — 43mm vs 42mm case width.
Which fits a smaller wrist better, the Garmin Fenix 7S Pro Solar Edition or the Garmin Forerunner 165?
The Garmin Fenix 7S Pro Solar Edition suits wrists around 44–60mm wide, and the Garmin Forerunner 165 around 45–61mm. The one with the smaller lower bound is the safer pick for a small wrist.

Yes — the schematics and photos above show both watches at matched scale, and our fit tool overlays each on your wrist width.
