How to Find Your Ring Size

Find Your Ring Size

The most reliable way to determine your ring size is to have your finger measured free of charge by a jeweller. If this is not possible, you can find your ring size at home using one of the methods below. Please note that slight variations may occur.

Measure the Inside Diameter

Place a ring that fits you well on a flat sheet of white paper. Carefully trace the inside of the ring using a fine-tipped pencil.

Using a ruler, measure the widest part of the circle you have drawn. Make sure you measure directly across the centre, as measuring off-centre may give an incorrect result.

Write down the inside diameter in millimetres and compare it with the ring size chart below.

Example: An inside diameter of 17.5 mm corresponds to a ring circumference of 55 mm and Turkish ring size 15.



Measure Your Finger Circumference

Step one: Take a piece of string or a narrow strip of paper to measure the finger on which you intend to wear the ring.

Step two: Wrap it comfortably around your finger and mark the point where the two ends meet.

Step three: Lay the string flat against a ruler and measure the distance between the marks in millimetres. This measurement is your finger circumference.

Step four: Compare your measurement with the chart below to find the correct ring size.
