Like its predecessor, Apple Watch 5, Apple Watch Series 6 is available in two sizes; 44mm and 40mm – the difference between these two is basically the slight differences in size and weight. Beyond that, both models offer the same features. This post compares the difference between Apple Watch Series 6 44mm vs 40mm specs and features to help you decide which size is right for you.

As you may already know, although Watch 6 has the same appearance as its predecessor, it comes with new features such as sleep tracking, blood oxygen monitoring and the Apple S6 chip which Apple claims is 20% faster than Watch 5 or SE. Other features include a handwashing app that reminds you to wash your hands and a hearing protection that alerts you when you have reached the recommended listening dose for the week. New workout modes have been added and the activity app has been redesigned and renamed to the Fitness app with the introduction of a Fitness Plan where you can get 3 months free when you buy an Apple Watch and $9.99/month on a subscription.

Other new features include the family app that allows family members who own an Apple Watch but don’t own an iPhone to still enjoy the benefits of an Apple Watch. the new cycling map app and an improved Siri. See all the features WatchOS 7

Which Size is Right For You?

It boils down to which size is right for you, the best way to know is to measure your wrist size or compare with other watches you’ve worn to determine that. I’ve always recommended the 40mm for women and those with smaller wrist sizes and the 44mm for men and for those with bigger wrist size. You can watch the video below to learn how to properly measure your wrist size.
