I'm looking at ordering a custom press-on set, but the seller only offers Small, Medium and Large with no mm measurements.

How do you know whether you'd be a Small, Medium or Large set if they don't tell you the measurements?

When I buy press-ons from the drugstore, I usually go by the 0-9 numbers, so l've never really paid attention to the mm sizes. Now I'm realising I have no idea what those numbers actually translate
to.

Do you know your nail sizes in mm, or do you just use the 0-9 numbers? If you know your mm sizes, what are they? I'd also be interested to know whether you'd consider yourself a Small, Medium or Large set.

I think I'm around 0-6-3-6-10. I have quite small hands, but I feel like my nail beds are fairly wide-although maybe they're just proportional. Most drugstore brands don't list the mm measurements, so l've never been able to compare.
