Ring Sizing: Your guide to buying a ring online

Buying a ring and deciding on the right size can be a tricky business when shopping online. If you can't try rings on before you buy, this guide will help you avoid any potentially expensive mistakes, and make the process hassle free!

When it comes to ring sizing there is no ‘average’ size or formula based on our clothing or shoe size (oh how I wish there was!). Our hands, knuckles and fingers are all unique and our finger sizes can fluctuate throughout the day. Temperature, hydration, hormones and medication can all impact our ring size.

Getting the size right for a ring that will be worn every day such as a wedding or engagement ring is vital! There is a real risk of losing it if it is too loose, and a risk of getting one stuck if it’s too tight. I have had to cut rings off customers who have got rings stuck on their fingers – not my rings of course!

While a ‘fashion’ ring may be purchased and worn on any finger, something more expensive and sentimental needs to be right. Follow these steps to ensure you get an accurate ring size!


Your finger size will change throughout the day based on a number of factors (such as temperature and physical activity). It is important to measure at different times during the day to make sure you get a true size or range of sizes.


Personal preference will play a big factor in how your jewellery feels when worn. A ring should not fall off and should slide comfortably over the knuckle without having to force it on. If you have to force it on or off it is too tight and likely to get stuck!


You will need the ring to slide over your knuckle without too much difficulty. If you have lager knuckles or arthritis in your finger joints you need to take this into account when measuring. Make sure you measure your knuckle as well as your finger where the ring will sit. Choose a size in between your finger size and knuckle size and check to be sure that a ring that size will fit over your knuckle.


Basic ‘at home’ method

(You may need an extra pair of hands to help you!)

1) Pick which finger you want to wear the ring on

2) Cut a thin strip on paper – 10cm long and 0.5cm wide

3) Get help wrapping the strip around your finger where you want the ring to sit. Don’t pull the strip tight

4) Mark the spot where the paper meets/crosses over

5) Measure the distance from the edge of the paper to your mark – This circumference measurement will convert to your ring size!

Converting your ring size There are two common ring-sizing scales of measurement:

· Alphabetical (or Wheat Sheaf) ring sizes used in the UK and other countries (for men and women

· Numerical ring sizes used in the US, Canada and much of Asia (for men and women)

Click to for your ring chart to convert your ring measurement. Find your ring circumference and read across the chart.

Visit your local jeweller Your local jeweller or high street jewellery shop will be able to measure your fingers if you pop in! They will be able to measure your fingers, or take a measurent from any exising ring you have. If you've got a ring that fits you perfectly, this is a great way to find out your ring size (or to secretly find out someone else’s size if you're buying a ring as a gift).

I have a range of sizing kits, which I can post out to ensure you get the most accurate size possible! These reusable kits are perfect to keep for future use when buying gifts for friends or relatives too!


If you find you are between ring sizes or your finger fluctuates dramatically between sizes throughout the day, it’s always better to choose half a size larger. Going up half a size will ensure that your new ring will slide on and off with ease and won’t get stuck!

I do advise that you get your fingers measured for an exact size before buying a wedding or engagement ring. If you need help, or would like to make an appointment or request a sizing kit then please get in touch via
