Know Your Ring Size

If you know your ring size but you have a different number than the size we use in Belgium (ISO 8653:2016 which defines the number in terms of internal circumfrence) use the table below to convert your size. We also recommend cross referencing your ring size by measuring the ring internal diameter and/or internal circumference.

HOW TO FIND YOUR RING SIZE

It is best if you can measure your ring size at a jeweler’s but if this is not possible, please follow the instructions below to measure your finger.

Use a strip of paper app the width of an average ring band (approximately 4- 6 mm).
Wrap it around your finger at the spot you put the the ring.
Mark the point on the paper where it overlaps.
With a ruler measure the length. This number is the internal circumference of the ring.

We recommend cross referencing this measurement with the measurement of an existing ring or a measurement you have received from a jeweler.

Use a strip of paper long enough to fit around your finger. Width should be around 5 mm

Warp the paper around your finger, Not too tight, aim for a comfortable fit but not too loose.
