41mm or 45mm: Which Size is Rigth For You?

With a wider and brighter display size as well as a higher screen-to-body ratio, the 41mm or 45mm can make a perfect choice for you. It’s no longer about display size since even the 41mm has a display size that allows you to see more at a glance in a very compact size.

Nevertheless, the 41mm size is recommended for individuals with thin wrists while we recommend the 45mm size for individuals with fat wrists.

To get the best size, you want to use a meter rule to measure the width of your wrist-ankle, then compare it to the 41mm or 45mm length to know which is more suitable for you. But bear it in mind that each of these two has a large display size that allows you to see more at a glance even though the 45mm size has a bigger display size.
