Garmin Forerunner 165 Music vs Forerunner 965
Size, specs & wrist fit compared

Which one fits you
On wrists narrower than about 50mm, the Forerunner 165 Music is the safer pick — it stays proportionate down to roughly 45mm, where the Forerunner 965 starts to hang over the edge. Above 50mm both sit cleanly, and the Forerunner 965 gives you more presence.
The Forerunner 965 wears larger than the Forerunner 165 Music (47.2mm vs 43mm case), giving it more wrist presence — and needing a wider wrist to sit cleanly.
The Forerunner 165 Music is the slimmer of the two (11.6mm vs 13.2mm), so it slides under a cuff more easily.
On the wrist the Forerunner 165 Music feels lighter (39g vs 53g, case only).
Among the 318 43mm watches we hold thickness for, the Forerunner 165 Music is thinner than 86%, so it wears flatter than its width suggests.
The Forerunner 965 is middle-of-the-pack for thickness among the 89 47mm watches in the database.
The Forerunner 965 is 4.2mm wider, 4.2mm longer, 1.6mm thicker and 14g heavier than the Forerunner 165 Music. 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 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.
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
47.2mm on a 55mm wrist
Across the wrist it works — 3.9mm spare each side — but wide enough that the edge of the case back lifts clear of the skin.
