What is ring size?
Ring size is a measurement used to denote the diameter of a ring. This measurement, in turn, must match the circumference of the finger where the ring is worn.
In the UK, there are 26 different ring size measurements ranging from letter A to letter Z.
From one letter to another, the ring size goes up by increments of 1.25mm, with half sizes in between.
Why does ring size matter?
To purchase a ring, you must know the correct size of the wearer’s finger. Otherwise, the ring will be too big or too small.
This is especially important if you’re buying a ring as a gift, or for a proposal.
You can be sure that the recipient of the ring will want to wear the ring straight away. If you get the size wrong, it can ruin a big moment like an engagement.

Measuring ring size in secret
If you want your proposal or special gift to remain a surprise, you may want to get the ring size in secret. For this, you have a few options…
#TOP TIP – Write down the ring size!
Ring size is one of those things that you think you’ll remember… but the truth is that most of us will soon forget it unless we write it down. So make a note (or even email it to yourself) so you’ll always have it to hand.
Warning: How NOT to measure ring size
If you’re buying an important ring, like an engagement ring, it’s best not to measure ring size with home-spun methods.
For example, a popular “hack” often seen on the internet advises you to tie a piece of string around a finger and then measure it. However, this method will almost always end in disappointment because a string is soft and stretchy, while a real ring is hard and keeps its shape.
Ring size can vary by fractions of a millimetre, and nothing except a properly calibrated tool will give you the correct size.
What is the average ring size?
In the UK, according to the latest statistics, the average ring size for women falls between ring size L and N. For men, the average UK ring size is T.
What happens if a ring is too big?
What happens if a ring is too small?
The obvious result is, if a ring is too small, that it will not fit your finger. Never force a ring on, as it may be extremely difficult to take off and can even cut off the blood supply to your finger!
Even if you can get a ring that is a little bit too small on your finger, the band will feel uncomfortable to wear. In the long term, it will leave a deep indentation on your finger.
The band can also snap as your finger exerts pressure on the metal.

If your ring needs to be resized
A ring resize has to be done by a specialist craftsperson. They will need to add or remove small amounts of metal to make up the difference between in size.
As a result, your ring’s band may become slightly thicker or thinner after resizing.
Rings that cannot be resized
Some rings are notoriously difficult or even impossible to resize.
For instance, eternity rings that have diamonds all around the band have to be made again from scratch. This is because each diamond has to sit at an equal distance from the next, and cannot overlap.
Very ornate ring styles, such as bands with milgrain work, can also be impossible to resize without leaving noticeable marks. Note that rings that cannot be resized may also be non-refundable.
