💍 The Only Ring Size Guide You’ll Ever Need
There’s nothing worse than ordering a beautiful piece of jewellery — something you’ve been daydreaming about — and then it arrives… and it doesn’t fit. It slips off. Or worse, won’t budge past the knuckle.
Sizing shouldn’t be guesswork — especially when you’re investing in something meaningful. So I’ve pulled together everything I’ve learned over the years designing and fitting rings for women who value quality, beauty and a touch of soul.
Here’s how to find your perfect size — without any of the faff.
🔍 Quick Tools to Measure Ring Size:
-
Use the Ring Size Guide Download: It’s printable, accurate, and super simple.
-
Order a Ring Sizer: I’ll send you one. Pop it on while you’re watching TV, and you’ll know your size in minutes.
-
Measure a Favourite Ring: Take its inner diameter (in mm) and match it on the guide.
🎁 Buying for Someone Else? Ring sizing for gifts can feel like mission impossible — but here are my tricks:
-
Borrow one of their rings (from the correct finger) and measure it.
-
Enlist a friend or partner to subtly find out.
💡 Good to Know:
UK sizes go alphabetically from A to Z+ — most women fall between J and P. (I’m an L½ on my middle finger if that helps). The width of the band also affects the fit — thicker rings feel tighter.
💡 Ring Sizing: Your Most-Asked Questions, Answered
1. Can I measure my ring size at home?
Yes, you absolutely can. A strip of paper, a piece of string, or one of our printable ring sizers can give you a good estimate — especially if you're in a pinch. But for the most accurate results, nothing beats trying a ring sizer or popping into a jeweller for a professional fitting. If you're gifting a ring and can’t measure in person, it’s worth erring slightly on the larger side — resizing down is often easier than going up.
2. How can I measure my partner’s ring size without them knowing?
A classic! If your partner already wears rings, borrow one they wear on the correct finger (discreetly, of course) and measure the internal diameter. You can also trace it onto paper. Otherwise, enlist a trusted friend or family member for intel — or go full rom-com and stage a try-on “just for fun” moment.
3. Do finger sizes change over time?
They do! Temperature, hormones, time of day, and even hydration can all cause slight fluctuations. For best results, measure at the end of the day when your fingers are at their most “average” size — not straight after a workout or when you’re chilly.
4. What's the difference between UK and US ring sizes?
In the UK, ring sizes are letters (like L or M), whereas the US uses numbers (like 6 or 7). If you're shopping internationally or just browsing Pinterest, use a ring size conversion chart to keep things simple. We’ve got one on our ring size guide page to help.
5. Can all rings be resized?
Most can — but not all. Rings with full eternity bands or intricate details all the way around can be trickier. If you're unsure, get in touch with your jeweller (or with me!) before buying. For gifting, choosing a ring that allows for resizing later is always a thoughtful move.
6. How snug should a ring feel?
You want it to feel secure, not restrictive. It should slide over your knuckle with a little resistance and sit comfortably without pinching or leaving a mark. A good fit feels natural — like the ring has always belonged there.
7. Is there an average ring size?
There is, but it varies! For women, it's typically between UK size L to N (US size 6 to 7). For men, it’s usually UK size R to T (US size 9 to 10). If you’re totally in the dark, starting in the middle of those ranges is a sensible bet.
8. Does the width of the ring band affect sizing?
It does — wider bands tend to feel snugger. If you're choosing a chunky design, consider going up half a size for comfort. Thinner bands are usually more forgiving in fit.
