Ring Size Guide by Francesca


Ring Size Guide

When shopping for rings in-store and online, we want to make sure that the ring you love fits like a charm!  

At Francesca, our rings are specified in standard US sizes, our smallest size is a US 5 (XS) and our largest size is a US 9 (XL).

Determine your ring size or the ring size of a loved one by requesting one of our free ring sizers or using our ring size chart and helpful tips below!

You can easily measure your ring size with one of our ring sizers or create your own!

How to Measure your Finger

You will need a piece of string, a pen/marker and some measuring tape or a ruler. We recommend measuring your finger size 3-4 times to eliminate errors. 

Step by Step Method to Measuring your Finger

  1. Cut a piece of string long enough to secure around your fingers.
  2. Wrap it around the base of your finger (make sure it’s at the widest part of your finger) and ensure it’s a snug yet comfortable fit.
  3. Using a pen or marker, mark where the ends of the string overlap.
  4. Lay the string flat against a ruler or some measuring tape and measure the length in millimetres.
  5. Use the Ring Size Conversion Chart below to find the corresponding ring size.

How to Measure a Ring You Already Own

Alternatively, you can use a ring that you already own by using a ruler/ measuring tape to determine the diameter of the inside of the ring, then find the corresponding ring size below. 

International Ring Size Conversion Chart

Our rings are sized as follows: 5 (XS), 6 (S), 7 (M), 8 (L) to 9 (XL).

The difference from one whole ring size to next is between 2-3mm in the circumference of the inner part of the ring’s band.

  1. Our dominant hands are generally slightly larger - ensure you measure the finger the ring will be worn on most, on the correct hand!

  2. Rings with wider bands may fit a bit tighter – if you are measuring a ring for a gift, try to measure one with a similar width as the style you are purchasing.  

  3. Make sure the finger is at a normal body temperature – fingers can expand or shrink when hot, cold or damp.

  4. Your fingers tend to change size throughout the day – the best time to measure your finger is towards the end of the day (when at its largest).

  5. If your knuckle is bigger, take 2 measurements and choose a size between them. The ring should fit over the knuckle but not be too loose or it will shift around.

  6. If the ring falls between two sizes, order the larger size up – just to be safe!



How Should My Ring Fit?

We’ve found there’s no such thing as a perfect fit, for most a ‘good fit’ means that your ring should be ‘comfortable most of the time’. Sometimes, your ring may be slightly loose or a little snug.

As a rule, rings should go on with relative ease and come off with little difficulty. Your ring should fit your fingers comfortably, snug enough that it will not fall off but loose enough to slide over your knuckle. 

A Surprise Gift for Someone Special?

Ask your loved one’s friends or family if they know their ring size. Borrow one of their rings (from the correct finger) and use the ring measurements in our guide to determine the correct size.

You could even use one of your fingers as a reference!  If you really don’t know someone’s ring size, selecting one of our standard ring sizes is usually your best option (between sizes 6, 7 and 8).

Still Unsure on Ring Sizing?

You can avoid returning/ resizing issues by visiting a Francesca store for a personalised size assessment. We are happy to exchange your Francesca ring for another size or style provided it is returned to the store within two (2) weeks of purchase (excludes sale) and in original condition/ packaging with all tags attached.

Otherwise, if you have any queries about the size of your Francesca ring, or any questions about returning or resizing, please contact our online customer service team. 

Our rings are stunning, worn on their own or easily stacked. From $69, most styles are available in silver, rose gold or yellow gold. Choose a style from a signature logo ring, a limited-edition statement or solid gold and diamonds!
