Below is a standard full size ring chart in mm, US and UK sizes. If you have any questions about your size or our sizes available please contact info@zohrehv.com.

If you are unsure of your ring size you can purchase a ring sizer from various online companies or go to a Jeweller to have your finger measured.

A rough guide to measuring your ring size is to cut a piece of paper around 10cm long by 0.5cm wide. Place it around your finger where you want the ring to sit and then mark with a pen where you feel you would have a comfortable fit for your ring. Measure the length with a ruler up to the mark drawn and translate into your ring size using the circumference column on the below table.

Please do note that your fingers do change size throughout the day, especially when you are hot or cold or even on medication. Bear this in mind and try sizing a few times throughout the day to get the most accurate measurement.
