How to Use a String to Measure Your Ring Size

Men's and women's ring size measurements at home using the string technique. Follow these steps:

-Take a piece of string or floss and wrap it around your finger's base.

-Make a pen mark at the point where the floss or string first overlaps.

-Measure the length of the string in millimeters by stretching it out along a ruler or measuring tape.

Your finger's circumference is the length you measured; divide that number by pi (division by 3.14 will suffice) to find the diameter.

To determine the standard ring size, use the ring size chart provided below to compare your finger's diameter.

How to use a tape to determine ring size

Your ring size can be determined with exceptional accuracy by using a tape measure. Simply wrap the base of the ring finger on which you want to wear the ring around with a measuring tape. Additionally, you should confirm that the wrapping was not done excessively loosely or firmly. If the tape measure, for instance, can slide past your knuckle, it's too loose. Next, measure the amount of millimeters that the tape overlaps on your finger, and then compare that measurement to the chart's ring sizes.

To get the ring size that fits your inner circumference, print out a true-to-size ring size chart and set your ring on the circles.

Make use of a ring size chart and ring sizer measurement tool for both men and women.

By employing a ring-measurement tool, you may determine ring size with the highest degree of accuracy. They're usually not too costly, and there are lots of options available online.

There are two types of ring-sizing tools: a keychain with a gradient of ring sizes on it or a thin measuring tape. You can easily loop the measuring tape-style ring sizer around your finger and adjust its tightness or looseness using the belt. Simply try the metal loops on your finger until you find the perfect fit on the keyring-style ring sizer, which contains loops for every ring size. Having ring sizers on hand might be useful while shopping for rings for other family members as well.

Tips for Ring Sizing

When determining your ring size, bear the following tips in mind:

-Think about your knuckle: Order a half size larger than what your finger size suggests if you know your knuckles are on the larger side. If not, you won't be able to move a ring into the proper position.

-Verify correctness by trying several times: According to the Catbird website, you should take three or four measurements of your finger because the size varies with temperature: It may swell more when you're warm and lessen when you're chilly.

-Measure the finger where the ring will be worn: For a comfortable fit, make sure to measure the finger you want to wear the ring on most frequently, as your ring finger may be smaller or larger on one hand than the other.

How do you determine whether a ring is too tight or too loose?

Over the knuckle, a properly fitted ring should remain in place. Turning a ring upside down will cause it to slide off the finger if it is too loose. Furthermore, an overly tight ring may leave an impression on the finger after removal or may not come off over the knuckle easily when pulled. A ring that is too tight may even cause the finger to swell or impede blood flow.

What Happens If I Resize My Ring?

Depending on the difference between the purchased and required sizes, the ring resizing process may involve adding or removing small quantities of metal to provide the optimum fit. Your ring might therefore be marginally slimmer or thicker after resizing. Often, these minute alterations are invisible to the naked eye.

The skilled jewelry artisans at Blue Nile follow exacting quality guidelines to ensure that your resized ring fits and sparkles flawlessly. Each ring is cleaned and polished once the band is resized and then given back to you.

What Happens If I Purchase The Wrong Ring Size?

Don't worry yourself silly over the size debate.

How to purchase a ring as a surprise

You should be discreet when measuring your partner's finger if you plan to surprise them with a gorgeous engagement ring or another eye-catching gift they can wear on their ring finger. Should that be the situation, you ought to:

Invite your family and friends to help.

Ask your significant other's parent, sibling, or best friend for advice on ring size. If they are unaware, they might propose that you try on rings just for fun and smuggle sizing into the schedule.

To determine size, use more jewelry.

If your partner's ring is readily available for loan, you can use it to measure their finger size by taking it to a jeweler or comparing it to the measurements on a ring chart that you can download.

Prepare to adjust the size.

You can always estimate your partner's ring size, but always err on the larger side. If it is too little, adding more metal to size up will be a little more difficult—and possibly more expensive. If it is too big, your neighborhood jeweler can easily adjust it.


There are many ways to measure your finger to know your ring size. You can measure another person's ring and ask them, or you can choose a larger ring size and resize it later, to find out someone's secret ring size.
