How to find your ring size without going to a jeweller
UpperEast JewelsYou’re about to buy a ring online and you realise you don’t know your size. The jewellers are closed, you don’t fancy asking the shop assistant, and the rings you’ve got at home are all different sizes (one was your grandad’s, one your cousin’s).
Don’t panic. There are 3 easy methods you can use at home, and they work really well. Here they are, in 5 minutes.
First: do you really need your exact size?
Honest question: if you buy from a brand that only sells adjustable rings, you’re covered. You don’t need a size.
Our Adjustable Flower Ring adjusts from about size L½ to Q½: the easy choice if you don’t know your size.
But if you want a fixed-size ring (sturdier, no squeezing it tighter or pulling it looser), you need your size. Here’s how.
Method 1 — String and a ruler
The easiest. You’ll need:
- A piece of string, fine wool or thick sewing thread
- A ruler
- A pen
How to do it:
- Wrap the string around the finger you want to wear the ring on. Make it snug but not tight (if you can feel your pulse throbbing, it’s too tight).
- With the pen, mark the point where the string overlaps.
- Lay the string flat along the ruler. Measure the length in millimetres from the start to the mark.
- That’s the circumference of your finger in mm.
- Check it against the chart below.
Ring size chart (mm and UK/AU sizes)
| Size on our product pages (circumference in mm) | Inside diameter (mm) | UK / AU size (approx.) |
|---|---|---|
| 48 | 15.3 | I½ |
| 50 | 15.9 | K |
| 52 | 16.6 | L½ |
| 54 | 17.2 | N |
| 56 | 17.8 | P |
| 58 | 18.5 | Q½ |
| 60 | 19.1 | S |
On our product pages the size is the inside circumference in millimetres (European sizing), from 48 to 60: for example, 52 means 52 mm. Letter sizes, the ones used in the UK and Australia, are in the right-hand column: they’re the closest match, give or take half a size.
Method 2 — A ring you already own
If you have a ring at home that fits perfectly on the finger where you want to wear the new one:
- Get a ruler with a millimetre scale.
- Measure the inside diameter of the ring (from inner edge to inner edge).
- Compare it with the “Inside diameter” column in the chart above.
Example: your ring = 17.2 mm inside → size 54 on our product pages (about N in letter sizes).
Method 3 — Print a ring sizer (more accurate)
Lots of jewellery brands offer “ring sizer” PDFs to print and cut out. Search Google for “printable ring sizer” and you’ll find free versions.
Careful: when you print, check the PDF hasn’t been resized. Most have a check box (e.g. “this rectangle should be 50 mm tall once printed”). If it doesn’t measure up, don’t trust it.
The 3 most common mistakes
Mistake 1 — Measuring in the morning
Your fingers are slimmer (less swollen) in the morning than in the evening. The result: you buy a ring that’s too small and feels tight by the evening. Always measure around 5–7pm, when your hand is at its “average” size.
Mistake 2 — Measuring when you’re cold
Cold hands = narrower blood vessels = smaller fingers. Measure on a mild day, not straight after coming in from the cold.
Mistake 3 — Measuring only the base of your finger
The point to measure is your knuckle (the widest part of the finger). The ring has to get over it. If you only measure the base of your finger, the ring won’t go on.
What if you’re between 2 sizes?
Always go for the bigger size. A slightly loose ring is comfortable. A tight ring cuts off your circulation, leaves a mark and hurts.
Example: your circumference comes out at 53.5 mm → between 52 and 54. Go for 54.
If you’d rather not think about it, get an adjustable ring. Our Adjustable Flower Ring, 18K gold plated, adjusts from about size L½ to Q½ without you having to choose. Just open or close it gently with your fingers to fit.
It’s also the safe choice for gifts: no risk of getting the size wrong. With the lifetime anti-tarnish guarantee.
