Garmin Venu 3S vs Venu 4 45 mm: Choose by Wrist Fit, Display, and Battery Mode
Start with wrist fit and display size: Garmin lists the 41 mm Venu 3S for 110–175 mm wrists and the 45 mm Venu 4 for 135–200 mm wrists. Battery estimates are mode-dependent rather than a simple generation win: Venu 4 is listed at up to 12 days in smartwatch mode versus 10, while Venu 3S is listed at up to 5 versus 4 days with always-on display and 21 versus 20 hours in GPS-only mode. These are manufacturer estimates, not measured results.

The buying question
Which exact Garmin watch fits the buyer’s wrist and display preference, and how do Garmin’s published battery estimates change with use mode?
The Venu 3S is the smaller watch with a smaller display; Garmin lists longer maximum battery life for the Venu 4 in standard smartwatch mode, but longer Venu 3S estimates with the display always on and in GPS-only mode.
Quick verdict
Choose Garmin Venu 3S – 41 mm, French Gray if
- Your wrist is within 110–134 mm, where only the Venu 3S published range fits.
- You prefer the smaller case and 1.2-inch display.
- Always-on display or GPS-only use is your planning scenario and you value the slightly longer Venu 3S published maximum for that mode.
Choose Garmin Venu 4 – 45 mm, Slate with Black Silicone Band if
- Your wrist is within 176–200 mm, where only the Venu 4 published range fits.
- You prefer the larger case and 1.4-inch display.
- Standard smartwatch mode is your planning scenario and you value the longer Venu 4 published maximum for that mode.
When the recommendation changes
- Wrist circumference below 135 mm or above 175 mm separates the listed fit ranges.
- Battery choice changes with mode: standard smartwatch estimates favor Venu 4, while always-on display and GPS-only estimates favor Venu 3S.
The differences that matter
Case Display And Wrist Size
What this changes: The listed wrist ranges overlap from 135–175 mm. Outside that overlap, Garmin’s published range points to one size; inside it, the smaller or larger display and case are the practical fit choice. The specifications do not establish which watch feels more comfortable on an individual wrist.[1]
Generation Feature Workflow
What this changes: For planning, the listed maximum favors Venu 4 in standard smartwatch mode, while the always-on and GPS-only estimates favor Venu 3S. Choose using the mode you expect to use; these figures are manufacturer estimates and do not establish real-world endurance or a tested winner.[1]

Value and trade-offs
One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.
Consider any current price difference only against the size, display, and usage mode you value. No fixed premium is justified by this comparison.
Current catalog price observations are a point-in-time snapshot, not price history; this comparison does not advise buying now or waiting.
Limitations
- No hands-on fit, battery, GPS, or display testing was performed.
- Battery figures are Garmin maximum estimates under named modes and may differ in individual use.
- Fit ranges are manufacturer guidance, not a comfort guarantee.
- Garmin comparison table cells that are blank are not treated as proof that a feature is absent.
Questions shoppers ask
Which watch is listed for smaller wrists?
Garmin lists the Venu 3S for wrist circumferences of 110–175 mm and the Venu 4 45 mm for 135–200 mm. The ranges overlap from 135–175 mm.
Does the Venu 4 last longer on one charge?
Garmin’s maximum estimates depend on mode. Venu 4 is listed higher in standard smartwatch mode; Venu 3S is listed higher with always-on display and in GPS-only mode. They are not independent real-world measurements.
Methodology and sources
Compared Garmin’s published case fit, display and band specifications, then reviewed its maximum battery estimates separately for standard smartwatch, always-on-display and GPS-only modes. These estimates are not independent measurements.
