Measuring the Diameter

The easiest way, to do this is if you have a ring which already fits the same finger. Download our printable size guide above and place your ring on them, you’ll need to close one eye to get a really accurate size. For a normal narrow ring, all of the lighter colour should fill the inside edge. For our wider rings, then all of the circle, including the darker border needs to fill the inside edge. You can also use a ruler to measure across the inside edge of the ring in millimetres.

Useful tip: Always measure your finger at room temperature. If it’s too cold your finger will be smaller; if it’s too hot your finger will be larger.

Measuring the Circumference

Use a measuring tape no wider than (2cm), or you can print out our ring sizer above to wrap around your finger. Do not use a piece of string or thread as this will follow your finger too closely and record an incorrect size. Wrap the measuring tape around your finger, making sure it slides easily over the knuckle. Using a pen, mark the tape at the point where it overlaps. Now measure the length in millimetres from the start of the tape to the pen mark.

Please note that all sizes are approximate due to the handmade nature of the majority of our rings The very best way to get an accurate measurement of your ring size is by visiting a jeweller and getting them to size your finger Please bear in mind that many of our rings (spinning rings in particular) are wide in design, and therefore may come up a little larger than standard sizes.
