Find Your Correct Measurement
With Our Ring Sizing Guide
If you would like to measure your ring size immediately, print out our Ring Sizing Guide. Before you print the Guide, be sure to check that ‘page scaling’ is set to “none” on your document’s ‘print dialog box’. Use the Ring Sizing Guide to measure a ring you have at home by placing the ring over the size circles until it matches the inside edge of your ring. Make sure the ring you measure fits the exact finger (and hand) you would like your new diamond ring on.
Start by cutting out the Ring Sizer. Wrap the ring sizer snugly around the widest part of the intended finger with the numbers visible, and insert the pointed end through the slit you made in the Sizer. Take note of the number that lines up with the slit. This is your ring size!

All Royal Asscher rings are specified in standard European sizes. View the conversion chart to see how these sizes map to finger circumference and how they convert in measurement units of other countries.
Helpful Ring Size Tips
Our dominant hands are generally slightly larger. So ensure you measure the correct finger on the correct hand!
Rings with wider bands will fit a bit tighter. If you plan to measure one of your partner’s rings, measure one with a similar width as the ring you intend to purchase.
When measuring, ensure the finger is at normal body temperature. Fingers can shrink or expand when hot or cold.
Your fingers tend to change size throughout the day. The best time to measure your finger is the end of the day.
If your knuckle visibly protrudes, take two (2) measurements and choose a size in between. Your ring needs to pass over the knuckle but not be too loose as that will cause it to shift around.
If you’re unsure, choose a slightly bigger engagement ring. Making a ring smaller is much easier than increasing its size. In addition, a size up might be ideal if you live in warm areas because the heat can make your fingers swell.
