Ring Size Guide

If you're wondering where to find your ring size then you've come to the right place! Getting an accurate ring size is an important step before investing in a precious ring. Rings which are too small can cause swelling, discomfort and can lead to circulation issues. Rings which are too large are likely to slip - and may even fall off your finger altogether. So whether you're looking to find the ring size of a loved one to purchase an engagement ring (congrats!), or just want to treat yourself but aren't sure about your size, here's our helpful guide.

Frequently Asked Questions

  • How do I find my ring size at home?

    You can measure your ring size at home using a piece of string or a thin strip of paper. Wrap it around the base of your finger, mark where it overlaps to form a complete circle, then measure the length with a ruler. Compare this measurement to the ring size chart above to find your size. Remember your finger can change size based on temperature!

  • Does ring size vary by hand or finger?

    Yes, ring size can vary between your hands and even between fingers on the same hand. It's common for your dominant hand to have slightly larger fingers. Always measure the specific finger on which you plan to wear the ring.

  • What should I do if I'm between sizes?

    If you find yourself between sizes, it's usually best to choose the larger size for comfort, especially if you're choosing a wider band, which can feel tighter.

  • How can temperature affect my ring size?

    Temperature can cause your fingers to expand or contract. Fingers tend to be larger in warmer weather and smaller in cold weather. For the most accurate measurement, try to measure your finger at a moderate temperature.

  • What is the best way to size a ring as a surprise gift?

    To size a ring as a surprise, you can borrow a ring that the recipient currently wears on the same finger and measure it with a ruler. Compare the value to the chart above.

Ring Sizes in Different Countries

Just to keep you on your toes, ring sizes can be different in different countries. the uk, usa and canada, france, germany, japan and switzerland all have a slightly different ring size scale - you can see how they vary, and convert one type to another in the ring size table below.

A Quick Ring-Size Geography Lesson

Ring sizes are laughably inconsistent across the world - brazil have their own thing going on; most of Europe has its own scale - apart from Germany who decided that wasn't good enough for them (Argentina agreed - they use the German ring size scale too).

UK ring sizes

The uk uses a system of letters, plus a fraction - e.g. A, A 1/2, B etc. the closer the letter to the end of the alphabet, the larger the ring size. once you get to 'Z', the uk ring sizes start adding on extra sizes with a '+' symbol followed by a number - e.g. Z+3, Z+3.5 etc.

note that this system is also used in Australia, New Zealand, Ireland and South Africa

US & Canadian Ring Sizes

You might also come across us ring sizes, which are also used in Canada. these are made up of numbers only, starting at '0000', '000', '00', '0', '1/2', '3/4' '1'; going up to '13.5'. The US system of ring sizes goes smaller than the UK, covering sizes all the way down to 31.33 mm in circumference. However, the UK system covers larger sizes at the opposite end of the scale.

Asian ring sizes

marked as 'Japanese' in our table (as this is where this scale originated), the Asian ring size is used across the entire continent, including India, China and the Middle East (though not Hong Kong, confusingly!). This scale is also used in some South American countries such as Peru and Bolivia. it's the simplest to figure out as it's literally just a case of counting up 1, 2, 3 - there's no fractions or letters to deal with! however, this means it covers fewer sizes than some of the other scales.
