BOT quick wrap sizes

I have 2 pair of BOT quick wraps that I bought ages ago. Horse that I am using them on now needs a size larger. However I have no idea what sizes I actually bought at the time & can’t find that information on the boots anywhere.

Does anyone know how to tell what size they are?

They’re measured vertically, just like with no-bows.
