Apple Watch 38 vs 42: Determining Factors
Whether you are a man or woman, everyone has a different wrist size. So, you can’t decide which smartwatch will suit you best solely based on your gender.
In general, people with small wrists are always advised to avoid large watches, as the chances of the watch being damaged are much higher. Of course, your taste is essential, so the most significant factor is the design of the watch.
Therefore, before buying a watch, it is recommended to try both of these models to determine which one suits you best. If you have a wider wrist, the Apple Watch 42 might be a better solution for you. It has a much longer band than the Apple Watch 38.
The smartwatch screen is essential because it affects the way you interact with the device. This is why the screens of portable devices are getting bigger. However, wearing a phone-sized smartwatch on your hand would be ridiculous. In this case, a bigger screen doesn’t mean a better user experience.
The most common smartwatch screen sizes are between 1.5 and 2 inches. The watches we present in this article are exactly in this size range. The Apple Watch 38 has a 1.5-inch screen. On the other hand, the Apple Watch 42 has a 1.6-inch screen.
However, in some cases, several millimeters more can help you navigate the system better. Therefore, if you have thicker fingers, the Apple Watch 42 might be a better solution for you.
Both models are equipped with the Retina OLED display. It is a 3D touch display protected with Sapphire crystal glass.

Apple has made sure that both devices have enough pixels to ensure the everyday use of all features. However, because of its bigger screen, the Apple Watch 42 has a higher resolution of 390 x 312 pixels.
On the other hand, the Apple Watch 38 resolution is 340 x 272 pixels. But, there is no difference between the two regarding image quality. In other words, whether you purchase the Apple watch 38 or 42, you won’t see individual pixels on their screens.
When people buy new devices, they want them to be as light as possible. In case you drop your device, there will be less damage. This rule also applies to smartwatches.
The weight of the Apple Watch 38 is 42.4 g. It is a winner in this segment because it weighs less than the Apple watch 42. The weight of the 42 mm version is 52.8 g.

The Apple Watch 38 and 42 have a built-in rechargeable lithium-ion battery. Due to its larger size, the Apple Watch 42mm has a bigger battery.
In fact, the 42mm version of every Apple Watch has a bigger battery. This is why these devices have longer battery life and better performance.
Therefore, the Apple Watch 42 from the Series 3 has a battery life of around 21 hours. The battery life of the Apple Watch 38 is 18 hours.
If your Apple Watch battery is draining fast, you should consider getting the GPS version of the Apple Watch 3.

On the other hand, the cellular model can use the cellular internet connection instead, which results in shorter battery life.
