A Guide On How To Accurately Measure Your Ring Size 

At Gear Jewellers we get asked daily about ring sizing, especially when buying an engagement ring and wanting to keep it a surprise. We understand it’s difficult to know your own ring size, let alone your partner’s ring size! Finger size is quite a precise measurement and guessing is not really an option. So here’s some tips and tricks to help find that perfect size!


How to Accurately Measure Your Ring Size?

Take a look at our ring size chart. In Ireland we use the alphabet but other countries use numbers. Use this handy guide if you already had your finger measured in a different country.

Drop in!

Most jewellery stores offer a free ring sizing service so drop into your local jewellers to have this done. It usually takes no more than a couple of minutes and is done using metal rings and a ring mandrel. 

Ring Size fluctuations 

Your finger size can fluctuate slightly throughout the day due to the cold, exercise or just general use of your hands. It’s best to have your finger measured later in the day as opposed to first thing in the morning as this will give the most accurate reading. 

Ring width & thickness

The width and thickness of a ring will play a role in what size you will need. A wide or thick band will feel tighter on the finger. In this case you will need to go up 1 size or a half size. Please note, not all jewellers do half sizes. At Gear Jewellers we believe that a half size can make all the difference. This is why we offer this service on all of our diamond engagement rings and wedding rings.

But I want to keep it as a surprise?

That’s perfectly ok! At Gear Jewellers we offer a free ring sizing service. We always recommend taking the average size for the proposal or gifting, which for ladies is a size M and for men it’s a size U. Then after the proposal you notice the ring doesn’t quite fit, you can pop back into us, we will measure the finger and have the ring adjusted accordingly.

I have a ring that she wears on her ring finger..

We can measure any ring that is brought into us using a ring mandrel and have the ring adjusted to that size, but you will need to be confident that it is worn comfortably and on the correct finger as we would prefer to get the measurement 100% accurate the first time!

I can’t get to a store for measuring!

Not to worry! With every diamond engagement ring purchased with us online we will send a complimentary at home ring sizer along with your order. These are easy to use, plastic belts that can be used over and over. Then simply post the ring back to us with your new measurement and we will have it adjusted for you. 

If you would like to avail of one our at home ring sizers then you can purchase themhere. They are €5 with free delivery!
