Method 1: Use the factory Sport band that comes with your Apple Watch. (Recommended Method)
Simply follow the steps that correspond with the circled numbers labeled on the illustration below.
Step 1: Determine which size Apple Sport band you use, either S/M or M/L. The size is located on the underside of your Sport band.
Step 2: Find the hole you use most often on the illustration below.
Step 3: The hole you use will point to your exact Spark*l size. That's it!
For Example: If you use the 4th hole on the S/M Apple Watch Sport band, you would be an XS in Spark*l sizing. If you have any questions, about custom sizes, using different Smart Watches, or anything else, feel free to contact us!
Method 2: Use our Wrist Sizing Guide.
Our Spark*l Wrist Sizing Guide is similar to a tape measure. Click the button to print out the guide and follow all instructions in order to find your correct size.
Method 3: Use a flexible tape measure.
If you have a flexible tape measure on hand, then you can measure the size of your wrist snugly and match the circumference to our sizes below. If you are between sizes, we recommend sizing to the larger size.
