Ring Sizes

As we are a Jewellers in the UK, we use UK ring sizing for measuring rings, this starts from A (the smallest) to Z. Half sizes are also available for a more perfect fit. We stock a wide range of sizes, with M being the most popular however, if we don’t have your size in stock we will order it especially for you.

It’s a good idea to know what your ring size is before you buy a ring. But we know that’s not always possible, especially if you’re buying it for someone else. If it’s not perfect, just bring it or send it back to us to re-size to make sure you get the perfect fit.

When measuring your finger you need to bear in mind that a wide band ring like a wedding or a fancy dress ring will need to be slightly larger than your normal size, so keep this in mind.

Many rings can be resized but this does depend on the design, for instance, a diamond set full eternity ring cannot be sized so this would need to be exchanged.

Guide to ring sizes

To help you find the right ring size this table shows the inside circumference of each UK ring size. Please note that this is a guide only and that having your finger measured by a jeweller is the most accurate way to find out your ring size.

Or alternatively, you can call us or email us your full name and address to sales@lesterandbrown.com and we can post you a free ring sizer which you can try on to determine the right size.
