A Complete Ring Size Guide for Online Shopping

Choosing the correct ring size is one of the most important steps when buying jewelry online. With the simple methods below, you can accurately measure your ring size at home and place your order with confidence.

You can measure your ring size in two easy ways:

Using an existing ring or using paper/string

Both methods are explained step by step below.

Method 1: Diameter Measurement Method (Measure Ring Size Using an Existing Ring)

This method is ideal if you already own a ring that fits the finger you plan to wear your new ring on.

Step 1

Place your ring on a flat surface and lay it on top of a ruler.

Step 2

Measure the widest inner part of the ring from inside edge to inside edge. Make sure to measure in millimeters (mm) and round to the nearest whole number.

Step 3

Find your ring size by matching the diameter measurement with a ring size chart.

Your ring size is now determined.

Method 2: Circumference Measurement Method (Measure Ring Size Using Paper or String)

If you don’t have an existing ring, this method is quick and effective.

Step 1

Cut a long strip of paper approximately 5 mm wide, or use a piece of string.

Step 2

Wrap the paper or string tightly around the finger where you will wear the ring.

*Don’t worry — the correct ring size is based on a snug measurement. The ring itself will not feel this tight when worn.

Step 3

Make sure the paper or string overlaps evenly. Mark the point where the ends meet.

*Paper is recommended over string for more accurate marking and measurement.

Step 4

Lay the paper or string flat and measure its length in millimeters (mm). Round to the nearest whole millimeter.

Step 5

Use this measurement to find the corresponding size in the ring size chart.

Your ring size is now determined.

Important Tips for Measuring Ring Size Accurately

Measure at the Right Time

Finger size can change throughout the day. Measure your fingers in the evening, when they are at their largest. Avoid measuring when your hands are too cold or too warm.

Consider Your Knuckle

Make sure the ring can comfortably pass over your knuckle. If your knuckle is wider than the base of your finger, measure according to the knuckle size.

Final Tip

If you’re between two sizes, we recommend choosing the larger size for maximum comfort.
