Ring sizing tips


When choosing a ring size

If you’re wondering how Pandora rings should fit, we can help. Choose the ring size of the largest finger you’ll be wearing the ring on. When measuring, round to the closest whole millimetre. Ideally, a ring should be able to fit well enough so that it won’t fall off. However, you don’t want it to get stuck, so make sure it’s also loose enough to fit over your knuckle relatively easily.

Use our plastic ring sizer for an accurate ring measurement.

Take measurements throughout the day

It’s important to remember that finger size changes throughout the day and can be affected by things like weather and hydration. We recommend measuring your finger several times over a day to calculate your ideal ring size.

Choose a larger size

Considering that your finger size changes throughout the day, it’s always best to choose a ring that’s slightly too large rather than slightly too small. You don’t want to risk getting it stuck on your finger.

Stackable rings

For stackable rings, select one size up from your normal ring size for a looser fit.

Wide shank rings

For wide shank rings, we recommend going one size larger than your normal ring size, as this ring has a wider band.

Finding Out Someone Else’s Ring Size

Want to surprise a loved one with a beautiful ring? The first step to finding their perfect piece of jewellery is figuring out their ring size. There are a few ways you can do this without raising any suspicion.

Check their jewellery

One of the easiest ways to find out someone else’s ring size is to check their other jewellery. Take a peek inside their jewellery box and analyze the rings they already have. Use a ruler to measure the diameter of a couple of the rings. That way, you’ll have enough information to closely guess your loved one’s ring size.

Use a piece of string

While it may be tricky, using a piece of string is a great way to measure ring size if you’re buying for a partner.

Wrap a small piece of string around your partner’s finger while they’re sleeping and use a pen to mark where the ends meet. Take the string to a jeweler and you’ll receive an accurate measurement of ring size.

Ask friends or family

Encourage your loved one to try on their friends’ or family members’ rings so you can get a better idea of what their ring size might be.
