Which size of smartwatch is best?
For most people the best smartwatch size is 40 mm to 45 mm. Because the screen is large enough to be easy to use and it still fits nicely on the wrist. If you have a wrist size between 15 cm (6.7 inch) and 20 cm (7.9 inch) or smaller, we would recommend an 38 mm smartwatch. Yet there is more range with a larger watch case.
The Garmin brand also sells smartwatches with a larger screen. This is cool and attractive to buy, but be aware that these run rather large for many ladies and gentlemen.
Does a smartwatch fits on a small wrist?
Yes, a smartwatch will fit a small wrist. Do not choose a size larger than 42 mm. For example, a model from 38 to 40 mm would be perfect. Keep in mind that for the best fit, the smartwatch should be between 1 and 2 cm from the edge of your wrist.
What is a good smartwatch size for kids?
Children’s wrists are still growing, so it is important to know what size of smartwatch to buy for them. For example, the Garmin Vivofit Jr, Fitbit Ace 3, Xplora or Kurio watch. The most popular smartwatch size for children is 28 mm to 32 mm which seems to be the perfect balance between being big enough for kids but not too big where they look like an adult wearing a watch.
Best smartwatch screen size comparison for men or women

What is the average size of a Smartwatch?

However, there are quite a few differences per brand. For example, the Fitbit is a lot smaller than the Garmin models by default.
Why are smartwatches so big?
Some people wonder why smartwatches are so big. This is because more electronics and a larger battery are required than the normal watches. That requires more space in the watch case. Nevertheless, the smartwatches are getting thinner and thinner these days.
