Before You Measure

01

Choose the Right Finger

Finger size can vary between your left and right hand, even for the same finger.

02

Measure Under Normal Conditions

Cold weather can make fingers smaller, while heat, travel, or swelling may make them feel larger.

03

Check More Than Once

For the most reliable result, measure your finger at least twice before choosing a made-to-order size.

04

Between Two Sizes?

For comfort, we usually recommend choosing the larger size, especially for wider bands or stacking rings.

Recommended Method:

Use the Printable Ring Size Guide

For the most accurate at-home measurement, download and print our Ring Size Guide at 100% scale (Actual Size). Before measuring, check the print accuracy using the credit card reference frame or the 1-inch and 5 cm reference lines. If needed, adjust the print scale slightly and print again. The printable guide includes a print accuracy check, true-to-size ring circles, and a paper ring sizer.

Method 01

Measure a Ring You Already Wear

Use this method if you have a ring that already fits the same finger comfortably.
After printing the guide at 100% scale, place your ring over the printed size circles. Match the inside edge of your ring to the circle that fits most closely.

If your ring falls between two sizes, we recommend choosing the larger size for comfort.

Method 02

Measure Your Finger

Use this method if you do not have a ring that already fits the finger you plan to measure.
After printing the guide at 100% scale, cut out the paper ring sizer. Wrap it around the base of your finger, pull it snugly but not too tight, and read the measurement where the end meets the scale.

Then compare your measurement with the Finger Circumference chart below.

No Printer?

Measure Manually

You can still measure your size without printing the guide.

Measure a ring you already wear

Measure the inside diameter of a ring that fits you well, using millimeters. Then compare your measurement with the Inner Diameter column in the chart below.

Measure your finger with paper or string

Wrap a thin strip of paper or string around the base of your finger. Mark where it meets, then measure the length in millimeters.
Compare your measurement with the Finger Circumference column in the chart below.
