Garmin Venu 2 vs. 2S: Does size matter? Finding the best Android smartwatch depends on a few factors. In many cases, size will play a part in your decision, like choosing between the new Garmin Venu 2 and 2S, for example. The company is introducing an assortment of new features that can be found on both models. The only difference to be concerned about is the size. The Venu 2 comes in a 45mm case, while the Venu 2S comes in a smaller 40mm case. When the original Garmin Venu was released nearly two years ago, it was only available in one size: 43mm. However, it's not unlike Garmin to release a smartwatch that comes in two sizes. One example is the Garmin Vivoactive 4, which also offered the 40mm and 45mm variants. There are plenty of new features to cover when it comes to the Garmin Venu 2 and 2S. Fortunately, both models offer the same features. Therefore, your decision will come down to your size preference.
