There are three ways to find your ring size.

Option 1 (most accurate)

If you have a ring you already love, grab it and your ruler. Measure the inside diameter to find your ring size. Another option is to use the Ring Sizer app.

Option 2 (most accurate)

Visit your local jeweler to get your finger sized. Or use our $3 ring sizer to size your finger.

Option 3 (less accurate)

To find your size, you'll need a piece of string or thread and a measuring tape. Then...

• Wrap the string around your finger and mark where the string overlaps
• Remove the string from your finger. Using a measuring tape or ruler, measure how long the string is from the end to the spot you've marked. This is the circumference of your finger
• Using the chart below, find the US ring size that matches the circumference you measured
• Note: The string should not be too tight or too loose when measuring your ring size, otherwise the size will not be accurate
