Ring Finger Size Chart: How to Find Your Ring Finger Size?

The ring finger is the fourth digit of a human left hand. It is between the pinkie and the middle finger. In many societies, it is so named for its traditional association with wedding rings, though not all use this digit as the ring finger (skip straight to the Ring Finger Size Chart).

A wedding ring should fit like a second skin; it shouldn’t be too tight to irritate your skin or restrict circulation, but it also shouldn’t be too loose to provide a fall-off risk. Getting the size right is vital because it’s one highlight of a wedding, engagement, or even just giving someone a ring.

What is a standard ring finger size?

Women’s ring finger sizes are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm), while men’s ring finger sizes are 10 (19.8 mm), 10.5 (20.2 mm), and 11 (19.8 mm) (20.6 mm)

How should a ring fit on your ring finger?

Your ring should snugly encircle your finger’s base, with no bulges or indentations. Push your ring up from the bottom and check if there is a small gap between it and your finger to see if it fits properly. This shows there is enough space. If you’re undecided, it’s probably best to size a ring up. It is simpler to alter a ring that is too big than one that is too small. No ring will fit perfectly, but try to get the best one you can. The more accurate you can gain your measurements, the better.

You might probably know your ring size as a simple number — somewhere between 5 and 10. But that number isn’t universal. Many factors can affect the size of the ring that fits you best.

There’s not a formula to pick the correct ring size across the board because everyone is so different and it depends on their lifestyles.

Finger Shape

There are various finger types, and these can affect ring fit and size. Your ring will fit snugly at the base of your tapered ring finger, which spreads downward toward the tip. Rings should fit snugly because they can easily fall off tapering fingers if they slide up.

Ring Width

Rings with thinner bands typically run a little larger, while rings with thicker bands fit more snugly, claims David Borochov, manager of R&R Jewelers in New York City. Your finger will enclose more area and fit more snugly the more metal there is around it. According to Borochov, “A thin size 6 band will not fit the same as a thick size 6 ring.” Choose a slightly lower ring size if your heart is set on a thin, delicate band (now quite fashionable) (pro tip: thinner bands make the center stone stand out more).

If you want to take matters into your own hands, you can use a few different at-home measurement methods with our printable size guide, which features both the diameter and circumference of each ring size.

Paper Technique

You can also use string, but it’s less reliable because it’s so thin and more likely to move about. Wrap a thin piece of paper around your ring finger, keeping it close to your knuckle where an engagement ring would realistically hit. Avoid wrapping too tightly and make sure the improvised ring is snug. Mark the area of the paper where the ends overlap with a pencil. With a ruler and your ring size in mind, measure the length of the paper and compare the result to the circumferences on the size chart.

Printable Ring Sizer Technique

The ring sizer is at the bottom of the size guide; print it and cut it out. By accurately measuring the dimensions above against a ruler, you can confirm that the guide is printed to scale. The sizer should be cut through the slot shown at the end, wrapped around the base of your left ring finger, and the pointed end inserted into the slot. Pull gently until it fits snugly. For your ring size, check the number on the sizer.

Ring Technique

Take a ring off your finger on your left hand that fits the ring finger and place it up against a ruler. Calculate the ring’s inner diameter and compare it to the size conversion chart. You can also get the exact diameter and ring size by printing the guide to scale and setting the ring directly on top of the ring photos. either narrow rings or wide rings always be careful when taking measurements.

Looking for a way to gauge your ring size secretly from your spouse? Don’t worry! Asking your partner about their ring size won’t wreck a surprise marriage proposal. Look for a knowledgeable insider who may know their ring size.

Put the ring on your finger and make a note of where it fits if your partner actually only removes their rings for five seconds to apply hand lotion. You or a jeweler should be able to duplicate the fit using the various ring sizers and charts.

In order to avoid getting the wrong size, it’s important to use the sizing tool and also the correct sizing method. The diameter measurement can be obtained using a paper strip. Ensure you get the correct measurement of the intended finger to avoid inconveniences and get the actual size.
