Ring Size Guide - Getting that Perfect Fit

Choosing the right ring size ensures your new piece fits beautifully and feels as luxurious as it looks. At Lawrence Paige, we want every detail to be just right – including your ring size.

If you already know your UK ring size, simply match it with the conversion chart below. If you're unsure, you can measure the inside diameter of a ring you already own or use a piece of string to measure around your finger, then compare your measurements to our size guide.

For best results:

• Measure at the end of the day when your fingers are at their largest.

• Make sure the ring will comfortably slide over your knuckle.

• If you're between sizes, we recommend sizing up for a more comfortable fit.

Still unsure? You can always reach out – we’re happy to help you find the perfect fit.
