Everything You Need to Know About Sizing a Ring

Shopping for a ring? Whether you’re looking for yourself or as a gift for someone else, here’s how to find the right size. Can I measure my ring size at home? Of course! Head to our ring sizing guide and print it out to get started — we’ve included a measuring bar at the top of the page to make sure that you print it to the correct scale. Then you can use it to find your ring size in one of two ways:

  • From an existing ring: Simply place your ring inside the circles until you find the one that fits. You’ll need to make sure that the inside of your ring sits nicely against the circle — it shouldn’t cover it up.

  • From your finger: You’ll need a length of string (or floss) for this, and it’s important to make sure that it doesn’t stretch. Wrap it around the base of your finger — or above the knuckle, if that’s where you intend to wear your ring — and mark the point where it completes the circle. Then, measure this length in millimeters or inches, and compare it to the circumferences in our table to find your ring size.

Is there a best time to get measured?

Finding your ring size is like shopping for shoes — your fingers can swell up slightly towards the end of the day, just as your feet do. You might also find that your fingers feel more swollen in the heat. So we recommend measuring your fingers around the middle of the day when they’re at a comfortable room temperature.

Does the style of ring make a difference?

As a general rule, wide bands feel more snug on the finger than slim, delicate styles, so you may want to size up slightly with our wider rings for a more comfortable fit.

Any tips for buying a ring as a gift?

Looking for the correct ring size for someone else? It’s tricky… but not impossible. The easiest way to get it right is to borrow one of her rings without her noticing, and measure it against our sizing guide printout. (If you don’t think you can get away with that, an even quicker method is to press the ring into a bar of soap and then use the imprint for comparison). 

But unless you’re shopping for an engagement ring, or a ring for a specific finger, remember that you have a little leeway: if you’re in the right ballpark, she’ll wear it on the finger where it fits best.

I’m ordering from outside the US. Are ring sizes the same everywhere?

Good question! Tiary uses US and Canada sizing, with our rings ranging from size 3 to 10. 

International ring sizes don’t correspond to the same numbers (and Australia and the UK use letters instead). So make sure to refer to our ring sizing guide for the correct fit. 

What if I get the size wrong?

Don’t worry — we’ve got you. At Tiary, we’ll resize your ring once for free within 45 days of the original shipment date.
