Boutico Ring size and conversion guide

If you are not sure of your ring size, we suggest you visit your local jewellery store for sizing as no charge is normally made for this. Otherwise, there is a very clever online ring size guide website at http://findmyringsize.com/. First, follow the instructions on Let's Start to calibrate, and then (on Step 3) CHANGE SCALE TO UK SIZES. Place an existing ring that you know fits over the circles until you find the one that is the correct size. The appropriate UK size is shown highlighted. If you are in doubt, we advise you to get it done professionally!

There are several different formats used for defining size of ring – dependent upon where you are in the world. Below you will find a simple conversion chart. We kindly ask you to use UK sizes whenever possible.

We hope that you will agree that it is your responsibility to provide correct ring sizes where applicable when ordering on line. If an item needs to be resized after purchase, we will try to be understanding, but there may be an extra charge (of up to £10 per item) plus return postage costs. Please contact us within 14 days of receipt if resizing is needed.

Tips for Ring Sizing

  • If you have a ring that is already comfortable, use this size as a guide.
  • Try and measure your finger size when your hand is at a natural ambient temperature. Your finger will give different sizes when very hot or very cold.
  • If in doubt, choose the larger size.
  • The ideal fit allows the ring to move easily over the skin when in place, without being either loose or slack. Pushing the ring up from the palm side should create just a little gap at the upper side.
