Size is the number one reason people hesitate before buying a ring online. The good news: measuring your size at home takes a minute, and if you do it right, you'll be accurate. Here are three ways, from easiest to less easy, and a few tricks we give customers in the shop.
How we measure size
On our site, the size is the inner circumference of the ring in millimeters. In other words, how many millimeters go "around" the finger. 52, for example, means a circumference of 52 mm. It's a simple system, because you can measure circumference at home with a ruler.
Way 1: string or a strip of paper
The quickest way. All you need is a piece of string (or a strip of paper half a centimeter wide), a pen and a ruler.
- Wrap the string around the base of your finger. Snug, but not tight.
- Check that the string slides over your knuckle. The ring has to get over the knuckle, not just sit at the base.
- Mark with the pen the point where the string meets itself.
- Open the string and measure the length to the mark with the ruler, in millimeters.
The number you got is the circumference, and that's your size. String stretches a little, so a paper strip is more accurate.
Way 2: a ring that already fits
If there's a ring that sits well on the right finger, it's the best measuring tool there is.
Measure the inner diameter of the ring with a ruler, side to side inside the circle, in millimeters. Then multiply by 3.14. For example, an inner diameter of 17 mm gives a circumference of about 53.4 mm. That's the size.
Make sure you measure the inside, without the thickness of the gold. A mistake of one millimeter in the diameter is already almost three millimeters in the circumference.
Way 3: a printable ring sizer
We made a printable ring sizer as a PDF file. It has a measuring strip to cut out, and a chart of circles you lay an existing ring on.
The only thing that matters: print it at actual size. In the print settings choose 100% or "actual size", not "fit to page". There's a 10 cm line on the page, and you measure it with a ruler after printing. If it isn't exactly 10 cm, the print was shrunk and the size won't be right.
Tips that prevent mistakes
- Measure at the end of the day. In the morning and in the cold your fingers are smaller, and after a full day they're at their biggest. A ring measured in the evening will be comfortable all day.
- Measure the right finger. Each finger has a different size, and so do your right and left hands.
- A wide ring needs a bit more room. For a wide ring (more than 6 mm), go up half a size.
- Between two sizes? Take the bigger one. It's easier to go down a little than to put up with a tight ring.
- Thick knuckle. If your knuckle is much thicker than the base of your finger, measure so the ring gets over the knuckle, even if it's a little loose at the base.
How to find out someone else's size
Buying a ring as a surprise? There are a few ways to find out the size without asking:
- "Borrow" one of her rings. Take a ring she wears on the same finger, measure the inner diameter (way 2), and put it back before she notices. If there's no time, lay it on a sheet of paper and trace the inner circle in pencil.
- Get help from someone close. A sister or a friend can ask without raising suspicion.
- Compare with your own finger. If her ring slides onto your little finger up to a certain point, mark that point and measure the circumference there. It's less accurate, but better than guessing.
And if it still comes out not quite right: under our terms, the first resize of a ring bought from us is free. So you don't give up a surprise because of the size. If you're planning an engagement ring, you're welcome to read our guide to choosing one too.
Your size changes over time too
Finger size isn't fixed for life. In summer, in the heat, fingers swell a little, and in winter they're smaller. Pregnancy, a change in weight or just the years can change your size by one or two. So if you measured a few years ago, measure again before buying a new ring, and don't rely on an old size from a ring you no longer wear.
Rings that are hard to resize
Most gold rings can be made bigger or smaller. A few kinds are very hard to change, so with them it matters more to get it right from the start:
- A ring with stones all the way around (eternity).
- A ring with a pattern or engraving along its whole length.
- A very thin ring, which a big size increase could weaken.
If you're not sure about a particular ring, ask us before you order.
The most accurate way

Not in the area? Send us a photo on WhatsApp of a ring you have next to a ruler, and we'll help you work out the size. And once you have a size, you can choose from women's gold rings or men's gold rings.
Frequently asked questions
How do I find my ring size without a sizer?
Wrap a string or a strip of paper around the base of your finger, mark where it meets itself, and measure the length with a ruler in millimeters. That's the circumference, and that's the size.
How do I turn a ring's diameter into a size?
Multiply the inner diameter by 3.14. A diameter of 17 mm is a circumference of about 53.4 mm.
What time of day should I measure my finger?
At the end of the day, when your hands are warm. In the morning and in the cold your fingers are smaller.
What if the ring I ordered doesn't fit?
The first resize of a ring bought from us is free, under our terms. Get in touch and we'll arrange it.
Does a wide ring need a different size?
Yes. For a ring wider than 6 mm, go up half a size, because it covers more of the finger.
Can I get measured in the shop?
Yes. At our shop at 64 Bilu St., Rehovot, we'll measure your finger in a minute. If you live far away, you can send us a photo on WhatsApp of a ring you have next to a ruler.
