Whether you’re buying an engagement ring, a ring for a special occasion (such as a birthday, anniversary or milestone), or even just treating yourself to a beautiful piece of jewellery, there’s one thing many people find a little bit difficult: choosing the correct ring size. Ring sizes can be challenging get right, but it’s important that you do - otherwise, that beautiful ring will sit in a box or need returning for re-sizing. So, how do you find out what ring size to buy? Well, here’s a ring size guide we have created, suitable for use when choosing any of the rings on our website. Our chart will ensure that you choose a ring that’s precisely the right size for you or your special someone, meaning it can be worn right away. And, the ring size converter below will also help you if you already know which ring size you’d like based upon a measurement in another country. 

How to measure your finger

Before you can use the charts below, you’ll need to know how to measure your ring size. This method below will teach you how to measure your ring size in the UK, using millimetres.

1. Take a piece of string or a piece of paper (no wider than 1.4cm or ½ inch), as this will help you to be accurate.
2. Wrap it around the base of the finger you would like to measure.
3. Use a pen to mark the point on the string or paper where it overlaps. The overlap will form a complete circle.
4. Take a ruler and measure the length of the string or paper from the starting end, to the end you marked with the pen.
5. Finally, use this measurement and compare it against the chart below to determine your UK ring size.

Of course, if you’re buying a ring for a gift or for an engagement, our advice guide on choosing an engagement ring contains some helpful tips on how to measure someone’s ring size discreetly.
Tips for measuring your ring size

• Measure when your fingers are at their largest - usually at the end of the day.
• Make sure you can comfortably slide the string or paper over your finger joints/knuckles.
• Measure your finger 3 or 4 times to make sure you’re getting a correct reading.
• Use a few different pieces of paper or string too - these materials can twist or stretch so it’s best to take a few readings.

Measuring your finger using our ring sizer chart

If you’d prefer not to measure your ring size using the tips above, simply download our ring sizer chart here. Here’s how to use it:

1. To guarantee that your ring measurements are perfectly precise, ensure that page scaling is set to ‘None’ when you print it off. Use A4 paper.
2. Then, double check you’ve printed the chart correctly by measuring the line on the right. This will show you whether or not scaling has occurred.
3. Take a ring that fits on the desired finger and place it over the circles on this chart.
4. Line up the ring by placing it in such a way that the inside edge of the ring matches the circle nearest in size. This measurement will reveal the diameter of the ring.
5. If the ring falls between two sizes, order the larger size. (Remember you may be able to order a half or quarter size).

Men’s ring sizes and ladies ring sizes

The ring size charts below can be used for determining both men’s ring sizes and ladies ring sizes. Male and female fingers are measured using the same scale - men's hands just tend to be larger than women's, and therefore will fall under the bigger sizes.
