Sizing Apple Watch Strap

In anticipation of purchasing an Apple Watch soon (after 12 September 2023 announcement) I thought it best to size my wrist for the strap. Downloaded and printed out the PDF with the Apple sizing guide. Made sure it was at 100% scale; the appropriate for checking credit card size was okay.

The problem is that there is no size number close to my wrist size. Even at the tightest the arrows do not point to a number. The nearest number (12) is at least 3cms away!

Anyone else experienced this problem and if so what strap size did you go for?

Although others might think different manufacturers devices are better I want something that will integrate into my Apple-only eco-system of Macs, iPhone and iPad as near seamlessly as possible. So not looking for Fitbit, Samsung, or others.
