Taper that shows ear size?

Hello friends,

I was wondering if you guys knew of a way to see what size my ears are currently? Kind of like a taper with markings or something. I blew out my lobes when I moved up to 1/2 in and now they have healed and Id like to start stretching again, but all of my jewelry that I have right now is either way too large or way too small. TYIA
