Beginning in 2020 Apple began offering Apple Watch band designs that were specifically sized to wrists. These bands included the Apple Watch Solo Loop and the Apple Watch Braided Solo Loop. These Apple Watch bands were available in sizes 1–12.
In order to allow individuals to determine their Apple Watch Band size, Apple provided three methods:
1. Printable Tool (online PDF)
2. Everyday items (using a “tailor’s measuring tape” or a narrow strip of paper)
3. Sizing Tool (in-store paper tool)
Options 1 and 2 were available online. After measuring your wrist, Apple provided an online converter that allowed users to enter their wrist size to a maximum of 10 15/16 inch (although the Solo Loop only fit wrists to a maximum of 8 2/16 inches).
This Sizing Tool was available to Apple Store Customers. The tools includes the directions on the outer package, instructing individuals through diagrams to open the package, peel back an adhesive dot, wrap the tool around the wrist, and determine the band size based upon the location of arrows printed on the Sizing Tool.
This example is unopened and was obtained at the Apple Store Michigan Avenue in Chicago in December 2021.
