How to find your ring size at home using our printable ring size guide

We've created a ring sizer for you to print off, as this is the most accurate way to measure your size. These are often free or inexpensive tools available online or at jewellery stores. Simply slip the adjustable ring sizer onto your finger and tighten it until it fits snugly, then note the size indicated on the tool.

  1. First, ensure the PDF is printed at 100% scale on A4 paper. Use a ruler to verify the scale on the printout.

  2. Select a well-fitting ring that is worn on the finger you wish to size.

  3. Place your ring over the printed circles on the chart. The inner edge of the ring should align perfectly with the outer edge of the circle.

  4. If your ring falls between two sizes, choose the larger one for comfort.

Ring size typically has a scale of A to Z, with A being the smallest and Z being the largest. Each letter indicates the ring's circumference in millimetres. Most jewellers provide half sizes to ensure a more precise and comfortable fit.

The average ring sizes in the UK

The average ring size for engagement rings and wedding rings varies slightly from country to country. A person’s ring size typically depends on their dress size, height, and of course, how they’re built.

The average men’s ring size in the UK differs from women’s, essentially because men and women tend to differ in height and build. That said, we all come in unique shapes and sizes, and our ring sizes are no different. There’s no completely fail-safe way to predict a ring size, but understanding the average ring size in the UK may help you learn where you (or your partner) fall in the sizing chart.

What is the average ring size for women?

The average engagement ring size in the UK is L. Likewise, the average wedding ring size for women is also L.

What is the average ring size for men?

The UK average men’s ring size is T – a whole seven sizes bigger than women’s.

International ring size conversion chart (UK, US, EU)

Just as with clothes and shoes, ring sizes are referred to differently across the world. The UK ring size system uses letters, from A-Z, with ½ size increments (for example, you may have a ring size of K ½).

The US and Europe use a numerical measurement system, so a typical question we often get asked is ‘what is a ring size 10 in the UK?’.

Converting ring sizes between the various systems needn’t be difficult – simply use our UK to US or EU ring size converter below to find your size.

Factors affecting your ring sizes

It’s important to know that your fingers aren’t always the same size, and they can change subtly throughout the day and over time, affected by:

  • Temperature

  • Ring width

  • Medications & hormones

  • Finger shape

  • Dominant hand

  • Pregnancy

  • Menstrual cycle

  • Time of the day that you measure

When is it best to measure your ring size?

The best time to measure your ring size is in the evening, as this is when your fingers are at their largest due to natural swelling that occurs throughout the day. Avoid measuring your ring size in the morning or after exposure to cold temperatures, as your fingers may be smaller. Ensuring the measurement is taken at the right time of day helps achieve a more accurate fit and ensures your ring is comfortable to wear at all times.

Quick tips for getting your ring size right

  • If possible, have your ring size measured by a reputable jeweller – they’ll likely have you try on a couple of sample sizes to see what works best, and will use a professional sizing stick. We offer this service free of charge – simply book an appointment at your nearest showroom.
  • Your hands swell slightly when hot, and are smaller than usual when cold. If you are particularly hot or cold, get your hands to temperature by running them under room temperature water
  • Determine whether the size is ‘leading edge’ or ‘centre’. At Queensmith, we tend to use the ‘leading edge’ measurement and craft our rings accordingly.
  • Consider your knuckle – If you have larger knuckles, ensure the ring can slide over comfortably without being too loose on the base of your finger.
  • Measure multiple times – Take measurements 3-4 times throughout the day to account for finger size changes due to temperature or activity.

Here at Queensmith, we can help you guess your partner's ring size when you order your ring. If we don't get it spot on, we'll reszie your ring free of charge within 60 days of collection or delivery.

Ring size is directly correlated to our height and clothing size, so if you know these details about your partner, we’ll be able to make a very good estimation.

Ring Size FAQs

Most people wear their engagement rings on their ring finger, the finger next to the pinky on the left hand. Some people move their engagement ring over to their right-hand ring finger once they're married, wearing only their wedding ring on their left hand, but this is quite unusual.

It’s unlikely many people know their own ring size, let alone their partner’s ring size. When it comes to finding out the ring size of your loved one, it’s best to consult with industry experts. At Queensmith, our consultants have a knack for estimating the ring sizes of people they’ve never met – but this isn't purely down to guessing.

As well as the sheer experience of handling rings, meeting with clients post-proposal and getting to know the ins and outs of ring sizing, our consultants use a combination of details to predict people’s ring sizes.

Don’t be alarmed if one of our experts asks about the height and dress size of your partner – more often than not, the correlation between height and dress size provides a great basis for predicting their engagement ring size! If you happen to have a photo of your partner with their hand in full view, this can also be a valuable tool in helping our consultants to get it right.

Whilst these trusty methods get accurate results more often than not, it is certainly not uncommon for a proposee to need their engagement ring resized following the big moment. It is unlikely the ring will need altering massively – this is usually a case of sizing up or down by a half to one full size.

If you or your partner’s Queensmith ring doesn’t quite fit right, we’ll resize your ring free of charge within 60 days of collection or delivery. As proposals are usually a surprise, we’ll invite you and your partner to come into the store following the big moment. Then, we’ll properly measure the right ring size and make any needed adjustments to ensure the perfect fit.

Yes, we can alter your ring to any size for free if needed within 60 days of receiving it. After that, you can book a resize any time you need – find the costs and more info here.

If your measurement falls between two sizes, we generally recommend opting for the larger size to ensure the most comfortable fit. Bear in mind that at Queensmith, we provide half sizes (such as a K ½) to help you find a much more precise fit.

Try not to worry too much if you're still unsure, we're on hand to give you the best advice, and if we don't get it spot on the first time, we'll resize your ring free of charge within 60 days of collection or delivery.

Not necessarily. One of the main factors that affects how a ring fits is the width of the band. Wider rings cover more surface area on your finger and tend to feel a little tighter, so you may need to go up a half or even a full size compared to a finer, more delicate band.

If you are ever unsure, booking an appointment with an expert is the best way to try on a couple of sample sizes and widths to see what works best and ensures a lifetime of comfort.
