Ring Sizer
Use a ring that already fits the finger you want to wear it on. Match it on screen, or print this page.
Step 1 · Set up your screen
Hold your phone upright, and place any bank or ID card upright too, short edge at the top. Don’t turn your phone sideways.
Lay the card flat on the outline below, then move the slider until the outline’s left and right edges line up with the card’s.
Set up once per device. Make sure the page isn’t zoomed in or out.
Step 2 · Match your ring
Lay your ring on the circle. Change the size until the line sits just inside the ring’s inner edge, with no gap showing.

Between two sizes? Choose the larger one. Wide bands fit more snugly, so consider going up a size.
