Why is knowing your ring size important?

It’s vital to know your ring size prior to choosing an engagement ring. Of course, re-sizing can be done for a ring that’s already been made. But if you buy the exact size ring you are assured that the integrity of the shank is super strong. In some instances (your diamond professional will guide you on this) re-sizing certain ring styles might affect the integrity of the stones set on the front of the shank.

So while re-sizing can be accomplished successfully, it’s always best to ask your diamond professional for guidance through this process—especially if you have a certain style in mind.

Resizing involves adding or removing a tiny bit of metal from the ring—most often in the exact back of the shank. A good bench jeweler can make this modification appear seamless—just like the ring was always its new size.

Measure your ring finger at the right time

Our bodies change a little or a lot during a day—and during different seasons. When it’s very cold, you may notice your shoes fit looser. The same thing is happening with your fingers. They are a bit slimmer due to the colder environment. Have you ever felt a bit ‘puffy’ after consuming salty foods or perhaps alcohol? There are many subtle changes that the body goes through during a day. So we recommend sizing your ring finger later in the day. Also—be aware of days that are too cold, or extremely hot. Avoid taking your ring size on those days to prevent you from getting a ring size that is not normal for you. Pay attention to your hands when you measure them later in the day for your ring size. Are they a bit warm? That’s good. You’ll get an accurate ring size reading at that time.


Printable Charts for determining ring size


Here’s a very handy method for checking your correct ring size. A printable chart is portable and very easy to use. This little tool makes measuring ring size on the go a breeze. Simply print out the chart and place a ring that the wearer already has on each round ring guide. Look for the one that is the nearest match to the person’s own ring. Each diameter shown on the chart has a corresponding US ring size with it.

But what if the person’s ring is in between two printed ring diameters? No problem, when that occurs (and it often does) then select the larger of the sizes to be sure you’ll be getting a good fit.

When you’re buying a ring as a surprise, you can enlist the help of her family or friends who can secretly get a ring from her to accomplish this task!

Using the string method for determining ring size

There’s more than one way to get an accurate ring size. It may sound overly simple, but the string or paper strip method works very well. And you’re bound to have one or both of those items to check the ring size. Here’s how you do it.

Wrap a piece of string or a strip of paper around the base of the ring finger.

Carefully mark the meeting point with a pen where each end comes together. Be careful not to pull the string or paper too tight. If it feels secure but comfortable, you’ve got the fit correctly measured.

Now measure your sized string or paper with a ruler or tape measure. Use the mm markings and divide that number by Pi or 3.14. That will be the diameter of the ring.

Look at the closest measurement on the paper ring size chart to find the correct ring size.

Seek professional assistance

Selecting your ring and making sure the size is exactly right is an important decision. So this might be the time to enlist the help of your diamond professional. He or she is expert in this field and understands the slight differences in rings styles. They’re here to help and are pleased to serve you. So many ring details known only to your professional can make their service an important part of your final choice.


Consider ring width and style

For example, if you were to select a ring with a very wide band, you may be surprised to learn that you often need to size up a ¼ to even a ½ size to get a comfy fit. Many other ring styles may have an impact on the final size you need.

Eternity bands, as another example are stunning pieces of jewelry. These bands are encrusted with diamonds all around the shank. Their message is one of never ending love—just like the ring has neither beginning nor end. But the extra diamonds on the ring may require sizing up just a tiny bit to ensure comfort when worn on a daily basis.
