Choose the Venu 3 for on-wrist calls, ECG (where supported), a barometric altimeter, more size options, and broader cycling features; choose the vívoactive 5 if you want core Garmin health and fitness tools for less.
Both are previous-generation models: Garmin has since released the Venu 4 and vívoactive 6. The comparison below can still help if you are considering these watches at a discount, but check current prices and compare the newer alternatives before buying.

1. Size, materials, controls, and display
The full-size Venu 3 is larger and heavier than the vívoactive 5 and has a larger 1.4-inch AMOLED display. The Venu 3S is the smaller Venu option, with a 41 mm case and 1.2-inch display—closer to the vívoactive 5 in screen size, but with Venu features and a smaller case diameter.
| Specification | Venu 3 | Venu 3S | vívoactive 5 |
|---|---|---|---|
| Case size | 45 × 45 × 12 mm | 41 × 41 × 12 mm | 42.2 × 42.2 × 11.1 mm |
| Display | 1.4-inch AMOLED, 454 × 454 | 1.2-inch AMOLED, 390 × 390 | 1.2-inch AMOLED, 390 × 390 |
| Bezel | Stainless steel | Stainless steel | Anodized aluminum |
| Weight with band | 47 g | 40 g | 36 g |
| Buttons | 3 | 3 | 2 |
All three use fiber-reinforced-polymer cases, AMOLED touchscreens, Gorilla Glass 3, silicone bands, and 5 ATM water resistance. The Venu’s steel bezel gives it a more premium appearance; its case is not all metal. The vívoactive 5 is the lightest, but it is not smaller in diameter than the Venu 3S. None is a rugged, button-first outdoor watch.

Choose the 45 mm Venu 3 if screen area matters most; choose the Venu 3S or vívoactive 5 if you prefer a smaller display. For small wrists, compare the Venu 3S and vívoactive 5 by fit and weight rather than assuming the vívoactive is the smallest.
2. Health sensors and wellness features
Both watches cover everyday wellness, including HRV Status, Sleep Coach, nap detection, Health Snapshot, Body Battery, and Pulse Ox (availability varies by country). The Venu 3 adds ECG support in eligible regions, skin-temperature tracking, and a barometric altimeter. The vívoactive 5 has no ECG or barometric altimeter.
Garmin’s ECG app is available only in supported regions, requires compatible software, and is intended for adults aged 22 and over. Garmin describes it as similar to a single-lead ECG that can detect signs of atrial fibrillation; it is not a general diagnostic tool. Pulse Ox and wrist-based heart-rate readings are estimates, not a substitute for medical advice or diagnosis.
The Venu 3 uses newer heart-rate hardware, but that does not mean it is always more accurate. Fit, movement, wrist contact, exercise type, and other factors affect optical readings. Choose it if ECG and the more advanced wrist-health hardware matter to you, not because the vívoactive 5 is inherently inaccurate.

3. Smartwatch features: calls, voice assistant, and music
The Venu 3 has a built-in speaker and microphone. When paired with a compatible phone, it can make and receive calls and access the phone’s voice assistant. It is not an LTE watch: calls require the paired phone nearby and connected.
The vívoactive 5 can show incoming-call notifications but cannot handle calls on the watch. It supports message replies using an Android phone’s on-watch keyboard. Both watches support notifications, music storage and playback, Garmin Pay, and Connect IQ; Garmin lists 8 GB of storage for the Venu 3 and 4 GB for the vívoactive 5. Compatible music services may require subscriptions.
Both work with iPhone and Android phones, though some reply features depend on the phone operating system. Choose the Venu 3 if calls or voice commands from your wrist are useful; otherwise, the vívoactive 5 retains much of the everyday connected functionality.
4. Fitness, hiking, cycling, and training
The vívoactive 5 is not a basic activity logger. Both models support GPS activities, a broad selection of sports, Garmin Coach, workouts created through Garmin Connect, workout benefit, recovery time, VO2 Max for running, HRV Status, and wheelchair mode.
The Venu 3’s extras are most useful for particular activities: its barometric altimeter supports floors-climbed and elevation tracking; it offers animated on-screen workouts, more outdoor and sport profiles, and broader cycling support, including compatible power meters and smart trainers. Three physical buttons may also be preferable during exercise if you do not want to rely on the touchscreen.

- INCLUDED IN THE BOX: Venu 3 | Charging/Data Cable | Documentation | Garmin Limited Protection
- BUNDLE INCLUDES: Additional 2 YR CPS Enhanced Protection Pack
For hiking and stairs, the Venu 3 is the better fit because of its altimeter and floors-climbed tracking. For cycling with a power meter or indoor trainer, its added compatibility matters. For general gym sessions, running, walking, or yoga, the vívoactive 5 already covers many buyers’ needs. Neither is Garmin’s strongest choice for serious runners seeking advanced race tools, maps, or training-readiness features; consider a current Forerunner for those priorities.
Both support wheelchair mode. Garmin says it changes activity tracking from steps to pushes and offers wheelchair-specific activities and weight-shift alerts; VO2 Max updates and incident detection are disabled in that mode.
5. Battery life and value
| Battery mode | Venu 3 | Venu 3S | vívoactive 5 |
|---|---|---|---|
| Smartwatch mode | Up to 14 days | Up to 10 days | Up to 11 days |
| Always-on display | Up to 5 days | Up to 5 days | Up to 5 days |
| GPS-only | Up to 26 hours | Up to 21 hours | Up to 21 hours |
| All-systems GPS | Up to 20 hours | Up to 15 hours | Up to 17 hours |
These are Garmin estimates, not guaranteed real-world results. Notifications, GPS sessions, music, Pulse Ox, sensors, and display settings affect battery life. The always-on-display estimate is up to five days for all three, so do not expect the headline smartwatch-mode figures with that setting enabled.
Garmin’s US comparison page lists the Venu 3 at $449.99 and the vívoactive 5 at $269.99, a snapshot that can change with discounts and availability. Their launch prices were $449.99 and $299.99 respectively. The Venu 3 is worth paying more for if you will use features such as calls, ECG, altimeter, its size choices, or cycling extras. If not, the vívoactive 5 offers core wellness and fitness features at a lower listed price.
Which Garmin should you buy?
Choose the Venu 3 if you want calls and voice-assistant access from your wrist, need ECG where supported, hike or track stairs, cycle with compatible equipment, or want the larger screen or smaller Venu 3S option. Choose the vívoactive 5 if budget, low weight, and everyday health and fitness tracking matter more than those extras.

Before buying, compare current prices and features with Garmin’s newer Venu 4 and vívoactive 6. The Venu 3 and vívoactive 5 can still make sense at the right price, but they are no longer the latest generation.

FAQ
Is the Venu 3 worth more than the vívoactive 5?
It is if you will use its calls, ECG (where supported), barometric altimeter, broader cycling support, or Venu 3S size option. If you mainly want core wellness, workouts, music, and GPS, the vívoactive 5 is the better-value option at Garmin’s listed US prices.
Can the vívoactive 5 make or answer calls?
No. It can display call notifications, but it lacks the speaker and microphone needed for on-watch calls. The Venu 3 can handle calls when paired with a compatible phone; neither watch makes standalone LTE calls.
Does the vívoactive 5 have ECG, and is Garmin ECG a medical diagnosis?
The vívoactive 5 does not support Garmin’s ECG app. The Venu 3 supports it in eligible regions with compatible software. Garmin says the app can detect signs of atrial fibrillation; it is not a general diagnostic tool.
Which watch tracks floors climbed?
The Venu 3 and Venu 3S have a barometric altimeter and track floors climbed. The vívoactive 5 does not have a barometric altimeter.

Which is better for sleep tracking and naps?
Both offer Sleep Coach and nap detection. The Venu 3 adds skin-temperature tracking, while the lighter vívoactive 5 may be more comfortable to wear overnight. Neither is a universal winner; consider which features and fit you prefer.
Is the Venu 3 more accurate for heart rate or GPS?
The Venu 3 has newer heart-rate hardware, but there is no universal accuracy guarantee; fit and activity affect optical readings. The dossier does not establish a general GPS-accuracy advantage for either watch.
Which has better battery life?
Garmin estimates up to 14 days for the Venu 3, 10 days for the Venu 3S, and 11 days for the vívoactive 5 in smartwatch mode. With always-on display, the estimate is up to five days for each; actual life depends on settings and use.
Do both watches support Garmin Pay, music, Garmin Coach, and wheelchair mode?
Yes. Both support Garmin Pay, music storage and playback, Garmin Coach, and wheelchair mode. Garmin notes that VO2 Max updates and incident detection are disabled in wheelchair mode.
