Rannka rings are offered in US unisex standard sizing 5-13.
Other sizes are available too (i.e. size 4, size 14, etc) and in between sizes (i.e. 5.5, 6.5, etc), just add a note at the checkout stating your size.
It is recommended that you chose a size as you would for any other ring as the stretch quality of rannka rings is already accounted for, unless otherwise noted on the product page.

I don’t know my Ring size.
1. Measure your fingers at home by simply wrapping your finger (at the place you want to wear a ring, if knuckle, than chose that spot) with a piece of thread or thin yarn; mark the circumference and lay flat on a ruler and add a note at the checkout.
2. Go to any jewelry shop near by and ask to have your fingers professionally measured.
