Determining the best watch size for your wrist is not a guessing game. You need to understand how to measure watch size and to be familiar with the watch sizes’ measurement basics.

For better understanding, here are some important key points to remember when sizing a watch.

  • Case Size (Diameter) and Thickness

    You might wonder how a watch’s case thickness is related to sizes. The principle is: As the diameter of a watch case increases or decreases, the thickness does as well.

    That is why you should first identify how thick the watch’s case should be. For example, in mostcollections of automatic watches, a case’s thickness may range from six to ten (6-10) mm. Based on this, the ideal case thickness of watch sizes for small wrists are usually from six to seven (6-7) mm.

    You have control when it comes to the diameter because you can choose a case size but not the case’s thickness which is decided by the manufacturer.

    Here is the standard case’s thickness of most watches in the industry:

    • 6mm – 8mm as thin,
    • 8mm – 12mm as average, and
    • 14mm – 18mm as thick

  • Watch Band Width, Kind, and Material

    When sizing a watch, it is also vital to determine your band width because it can greatly affect the way your watch will look on the wrist. It is recommended that you choose a band ora leather watch strapthat is half of the case diameter such as the following:

    • Case Diameter: 36mm, Strap Size: 18mm
    • Case Diameter: 40mm, Strap Size: 20mm
    • Case Diameter: 44mm, Strap Size: 22mm

On the other hand, choosing the kind of strap or band and the material used should be based on your preferences. Metal bracelets may come in a mesh or a link form and are mostly preferred by men with larger wrists. At the same time, metal bands are still popular for women’s watches although most prefer the leather straps. Fabric or nylon straps are commonly used for sports watches though these kinds of straps can also be seen on casual watches.


To determine a wrist size or watch sizes for small wrists:

  1. Get a measuring tape or a foldable ruler and then wrap it around your wrist.
  2. Make sure that the tape or ruler is neither too tight nor too loose on your wrist before getting the measurement.

After getting your size, it is important to understand the proportion of your wrist size and the case diameter. So, to answer the question, what watch size should I get for my wrist? Refer to these sizing guides:
