Apple recommends the 40 mm version for wrists from 130 to 200 millimeters. Again, you can measure your own wrist if you're not sure, but it's generally more comfortable for smaller wrists. If you want the largest and clearest screen available on an Apple Watch, the 44mm one is for you. You'll also benefit from a larger battery and, therefore, longer battery life with 44 mm.
If you have a small wrist or just want the cheaper Apple Watch, then the 40mm one will fit you perfectly. The two 38 mm and 42 mm Series 3 watches are almost the same in terms of their characteristics. The main difference is in the size and the available viewing area. Those who prefer larger screens should definitely opt for the 42mm Apple Watch with a viewing area of 740 square mm.
The 38mm watch is a budget option: you can have a decent screen and save a few dollars. While Apple's strap options are always updated, it's worth noting that some straps are specific in size, as you can see by looking at several available models of the Apple Watch Series 6.One thing that has remained constant over the years is that Apple releases every Apple Watch in 2 sizes. The 6 Series is the latest and most advanced version of the Apple Watch and has some incredible features, unlike previous versions.

However, what size is best for you? We do an Apple Watch size comparison and try to answer these questions here, along with our own observations on the watches currently available. While the strap of an Apple Watch can be adjustable, it's essential to consider the size of the case before buying it. When I queued up for the first test session, I swore that the watch on display in the window was 38 mm, but the Apple employee said it was 42 mm. In a survey on his site, most men preferred a watch between 40 and 44 mm in size, suggesting that the larger size of the Apple Watch is a good bet.
The 42mm Apple Watch has a viewing area of 759 square mm, while the 44mm Apple Watch has 977 square mm of the total viewing area. The internal functions, sensors, compatibility with Health App and everything else that might make you curious about the Apple Watch are the same in both sizes. In Ask Men, the Watch Snob says that 39 mm is the right size, which points to the smaller Apple Watch of 38 mm, so there really isn't a perfect answer. When in doubt, go to local stores and see if you can try on an Apple Watch in each size to see which one you prefer.
According to Bain's expert opinion, the smaller Apple Watch should work perfectly well for a man of my slenderness. Therefore, if you were already using a Series 5 watch that was comfortable enough and needed an upgrade, we recommend that you go back to the same size.
