Choose how you’d like to find your ring size:
Let’s determine your screen’s dimensions. Then we can accurately measure your ring size.
Use the + and - buttons to adjust the slider until the red lines match your card’s height.
Use the + and - buttons to adjust the markings until the measurements on both the screen and your ruler match up.
Place your ring on the circle below. Use the + and - buttons to adjust the size of the circle until you can’t see any blue within the ring.
You’ll know you’ve adjusted correctly when you see only pink inside the ring, and only blue on the outside. Click “Apply” when you’re finished.

Wrap a non-stretching string, ribbon, thread, or thin paper strip comfortably around your ring finger, near the knuckle.
Using a pen, mark the precise location where the string overlaps, aiming for minimal markings for optimal accuracy.
Remove the string with the mark you made. Then, using a ruler, measure its length either in mm or inches. Input your measurement above.
