Use the instructions below to measure your ring size and find your best fit. Start by measuring your finger’s circumference or the diameter of a ring you already own. Next, use the ring size chart to find your size and choose the style you love. If you’re between sizes, we recommend choosing the next size up.
How to Measure Your Circumference
Circumference is the measurement around the base of the finger
You'll need:
5mm wide strip of paper
Pencil of fine tip pen
Ruler
Step 1:
Cut a long strip of paper that is 5mm wide.
Step 2:
Wrap a strip of paper around the base of desired finger. For the most accurate result, pull paper as tight as possible.
*Don’t worry! The correct ring size is determined based on a tight measurement. The ring itself won’t fit that tight.
Step 3:
Make sure the paper is evenly overlapped and pulled tight, and mark where the strip of paper meets itself.
Step 4:
Measure the length of the strip of paper in millimetres. Round to the closest whole millimeter.
How to Measure Your Diameter
Diameter is the measurement across the inner width of the ring
You'll need:
A ring that fits you
Ruler
Step 1:
Find a ring that fits.
Step 2:
Lay ring on top of ruler, and measure the widest area inside the ring from inner edge to inner edge. Round to the closest whole millimetre.
Tip:
If your ring is a different shape and is not circular, measure the shortest distance across.

Ring sizing tips for wide bands
Wide bands, like Pandora’s statement rings, fit more snugly than slim styles due to their fuller surface. For a comfortable feel, consider going one size up.
