Ring sizes vary between brands, so we strongly recommend measuring with our Sizing Kit before you order. The kit contains sample rings in every available size and costs $4.99. You can also follow the measuring instructions on our Size Guide page. Not sure which model to choose? See b.ring G2 vs Pro: which ring and size to choose.

b.ring G2 and b.ring Pro are available in US 7 to US 12. b.race R1 is one size and adjusts to fit wrists from 180mm to 235mm. Choosing a running band? See our running smart band guide.
