Use this chart to convert your measurements into US ring sizes to order.
If your size comes out smaller than available choose the smallest size from the drop down menu and put your actual size in the notes.
If your size is larger than available please use the contact form to reach out so we can set up a custom order.
Please keep in mind that not all metals can be used for all sizes, larger sizes are only available in nickel free stainless and titanium to ensure the splint will be strong enough. 
Splints that cannot be made larger or smaller than the available sizes will be noted as such in their description.
