How to Find Your Ring Size
Unsure where to start? Finding the right size doesn’t have to be complicated. Follow one of these easy methods to measure accurately at home or in-store.
Option 1: Measure an Existing Ring
Place a ring you already own flat across a ruler and measure the internal diameter (the clean circle inside the band) from edge to edge. Record this in millimetres, then use our Ring Size Chart to find the matching UK size.
Option 2: Measure Your Finger
Take a slim piece of string, ribbon, or paper and wrap it around the base of the finger. Mark where the ends meet, then lay it flat against a ruler to measure in millimetres. It should sit comfortably — snug, but never tight.
Measure later in the day when your hands are warm and at their most natural size.
Helping You Guess a Size
Planning a surprise? Here are a few discreet ways to estimate your partner’s size:
- Borrow a ring they already wear on that finger and take it to a local jeweller for measurement.
- Wrap a soft string around the inside of their ring and measure its length.
- Or ask a friend or family member to help guide them into a jewellery store — a timeless classic that still works beautifully.
Most engagement rings fall between sizes J, L and O, with M being our most commonly ordered.
Resizing Options
Before Purchase
If you’re keeping a proposal a surprise, an educated guess is perfectly acceptable. Simply order the most likely size, and we can resize the ring before dispatch at no extra cost.
After Purchase
If your ring arrives slightly loose or snug, our first resize is complimentary. Visit our Cheltenham boutique and our team will refine the fit with care and precision.
For guidance on sizing or adjustments, you can always contact us — we’re here to help.
Tips for the Perfect Fit
A well-fitted ring should slide over the knuckle with light resistance and rest comfortably at the base of the finger — secure, but never tight.
Remember: your hands can change size slightly throughout the day or with temperature. For best results, measure later in the afternoon and take into account band width — wider rings feel tighter than slender bands.

Sizing FAQ
How can I measure my ring size at home?
You can measure your ring size in two simple ways.
Use a ring you already own and measure the internal diameter in millimetres, then match it to our UK ring size chart.
Or, wrap a slim strip of paper or string around the base of your finger, mark where it overlaps, and measure in millimetres.
This gives an accurate guide for your ideal fit.
What time of day should I measure my finger?
Measure later in the day when your hands are at their most natural size.
Fingers can be smaller in the morning or in cooler temperatures, which may cause your ring to feel tighter later.
Do wider bands affect ring size?
Yes. Wider rings tend to fit more snugly than slimmer bands.
If you’re choosing a bold or heavy design, we may recommend going up half a size to ensure lasting comfort.
What are the most common UK ring sizes?
At Beards, our most frequently ordered size is M.
Engagement rings often fall between J and O, with L, M and N being particularly popular starting points.
Can Beards resize my ring before it’s dispatched?
Absolutely. If your ring is being purchased as a surprise, we can resize it before dispatch free of charge on Beards engagement rings.
Simply let our team know your preferred size during checkout or via our contact page.
Is resizing after purchase free?
Yes. Your first resize is complimentary on all Beards engagement rings.
If your ring feels a little loose or snug, visit our Cheltenham boutique and our expert jewellers will perfect the fit.
How do I discreetly find my partner’s ring size?
Borrow a ring they wear on the same finger and have it measured by a jeweller, or carefully measure its inner diameter at home.
Alternatively, ask a friend or family member to take them ring shopping under another pretext — it’s a time-tested approach that works beautifully.
