How to Measure Your Ring Size at Home
In This Guide
Finding the right fit shouldn’t be guesswork. We offer three simple ways to determine your UK ring size—ranging from Size A to Z—to ensure your piece sits perfectly from day one.
Use Our Free Ring Sizer
We will post a free, reusable ring sizer to your home. It is designed to be gender-neutral and easy to use. Simply wrap the sizer around your chosen finger and adjust until it feels comfortable.
The Perfect Fit: Your ring should be snug enough not to slip off, but loose enough to slide over the knuckle with a small amount of resistance.
Make Your Own Ring Sizer
What you’ll need:
- Printer & paper
- String, yarn, floss, or a thin strip of paper
- Pen or marker
- Ruler
Steps:
1. Cut a piece of string, yarn, floss, or thin strip of paper to at least three inches long.
2. Wrap one end of the string around the base of the intended finger.
3. Using a pen or marker, mark where the end of the string overlaps with the rest.
4. Lay the string flat and use a ruler to measure the length between the end and your mark in millimeters.
5. Use the Ring Size Conversion Chart to match the millimeter length to the corresponding ring size.
Print a Ring Sizer
What you’ll need:
- Printer & paper
- Scissors
Steps:
1. Print the Printable Ring Sizer & Conversion Chart. Set page scaling to “100” in your print settings and use A4 standard paper.
2. Cut out the ring sizer and the slot as instructed.
3. Wrap the paper ring sizer snuggly around the base of the intended finger so that the numbers are visible and insert the pointed end through the slit you made in the sizer.
4. Note the number that lines up with the slit; this is your ring size! Remember that quarter sizes are also available if your sizer indicates that you are between whole and half sizes.
Ring Size Chart
All of our rings are crafted in UK sizes. View the chart below to see how UK sizes map to finger circumference and convert to international sizes. Engagement rings, wedding bands, and fashion rings all follow the same size format.

How Should a Ring Fit?
A ring that fits appropriately will slide over your knuckle with minimal friction and sit snugly on your finger without feeling too tight. You should feel slight resistance but not need to apply too much force to take it on and off.
What to Do if You're in Between Ring Sizes
If you’re in between sizes, we suggest sizing up rather than sizing down. Finger size can fluctuate throughout the day, and a ring that is too tight may not come over the knuckle easily—which can be painful. Additionally, there are simple, at-home ways to make a slightly loose ring feel tighter, but you’ll need to consult a professional to size it up. Remember, if a standard letter doesn’t feel quite right, contact us and we can craft your design in a half-size (e.g., M½) to help you find the perfect fit.
Ring Size Tips
Dominant Hand: Our dominant hands are generally slightly larger – measure the hand you plan to wear the ring on.
Temperature: Ensure your body temperature is normal – fingers tend to shrink when cold and expand when hot.
Daily Fluctuations: Fingers change size throughout the day based on the water we drink and the food we eat – the best time to measure is towards the middle or end of the day.
Pronounced Knuckles: If your knuckle is pronounced, you may want to measure both the knuckle and the base of the finger. Then, choose a size in between those measurements, as rings need to fit over the knuckle but not be too loose or tight to wear comfortably.

Ring Size FAQ
Of course. We offer half-sizes across our entire range to ensure your ring sits exactly as it should.
Should the fit not be quite right, please contact us to begin our complimentary resizing process. This service is available within 60 days of your piece being dispatched or collected from our showroom. We will work with you to confirm the adjusted size and refine the fit free of charge.
To achieve the perfect fit, our jewellers will carefully add or remove a small section of metal from the back of the band before seamlessly soldering it back together. The structural integrity remains uncompromised—the adjustment will be entirely invisible to the eye.
While every hand is unique, there are some common benchmarks to guide you:
For Women: The average UK ring size typically falls between L and N, with M being our most requested size.
For Men: The average size usually falls between R and T, with S being the standard baseline.
To determine your precise size request a free physical ring sizer to be sent to your home.

If the proposal is a surprise, selecting a standard size—typically an M for women or an S for men—is the safest starting point. You might also consider borrowing a ring they already wear (for the correct finger) or consulting a close friend.
