Watch Band Size

Find the right band size for your Samsung smart watch

If you’re getting bored of always wearing the same strap with your Samsung smart watch, you can simply get a new watch band. They are available for purchase on our website. But which one is the right size for your Samsung watch? And can you use a band that is meant for a different model? We have your guide right here.

How to change the band on your Samsung smart watch

If you're bored of wearing the same band day after day, we have good news. Samsung watch bands are easily replaceable. All you need to do is make sure the new band is the correct width for your watch model. Once you have one that matches your style, you can swap them out in just a few quick steps to further customize your look.


Note: When purchasing a Galaxy watch you can select from a variety of styles and colors of watches and bands that best suits you.

Find the correct width for your watch

Official Samsung watch bands are offered in two sizes. Size S/M fits 130mm - 190mm wrists. Size M/L fits 145mm - 205mm wrists. To find the right size for you, you'll need to measure your wrist. If you don't have a cloth or paper tape measure, just use a string!

  1. Take a piece of rope or string and wrap it around your wrist.
  2. Use a pen or marker to mark the spot where the string meets.
  3. Take the string and lay it flat on a ruler or tape measure to find the size in millimeters.

Note: The leather band may make a squeaking sound where it connects with the Galaxy Watch3 due to characteristics of the material. This is normal and you can address this issue by applying leather care products to the band at the connection point.

Change your watch band

Once you know the correct size of your watch, you can change the band by following a few quick steps.
