It is especially important to get your ring size accurate when buying a ring on line.  So I thought I would start with some basic considerations in the hope you you being thrilled with your purchase.  Before we start, remember that all your fingers may be different sizes.

Our Fingers and Finger Sizes Expand and Contract

Our fingers expand and contract due to different environmental factors such as heat, cold, humidity, and our level of activity. Often, our fingers are smaller when we wake up and get bigger as the day goes on. For this reason, getting sized for a ring is usually better done later in the day than earlier.

There are Four Things Not to Do Before You Get Your Finger Measured for Size

  1. Work out. It makes your fingers bigger!
  2. Eat salty nuts, or chips, etc. because salt makes your fingers bigger.
  3. Eating apples. This surprised me too, but they make you lose water weight, making your fingers smaller.
  4. Or, do strenuous or even repetitive work with your hands. This makes your fingers bigger.

Five Other Considerations About Measuring your finger for a Ring

  1. Humidity and heat enlarge your fingers
  2. Your finger become smaller in colder temperatures, so never measure cold fingers.
  3. Your fingers go up and down in size during the day and during the month.  Therefore, measure your finger at the end of the day, when they are largest.  And, measure the largest part of your finger.
  4. Some medications can even affect your finger size
  5. Measure 3-4 times to make sure you have an accurate measurement.

How Should a Propper Fitting Ring Feel?

A proper fitting ring should slide over your knuckle with a little friction and fit snugly on your finger, but not too tight. You should feel resistance and need to apply a little extra force to remove the ring backwards over your knuckle.

Are Large knuckles a Problem?

If you have large knuckles due to arthritis for example, you may prefer a Comfort Fit ring.  These rings are made like cuffs with a space in the back and can even be put on like a cuff.  Custom rings are possible!  And, I will have these clearly marked in the Ring section of my Products.

Ring Width

Another consideration is the width of the ring.  My suggestion is to go with the one that looks the best on your hand.  You can always visit your local jewelry store to get an idea.  And then you can get your finger measured for your size as well.  You can also try Michaels, if you have one near you because they sometimes carry ring sizers.

That being said, many men will order a 8mm or 6mm wide wedding bands. Most women order a 4mm wedding band.

If you are looking for a band width of 1 to 4mm, use narrow finger-sizing gauges.

If you are looking for a band width of greater than 4mm, use the wide finger-sizing gauges.

Wider Bands

Wider bands fit more snugly than narrow bands, so the width of the ring sizer will affect the size. Generally, if sized with a narrow ring sizer, you would want to size up 1/4 size for rings 5-6mm wide and 1/2 size for rings 7-8mm wide.

Can I Get My Ring Size From a Favorite Ring I Own?

Great question!  The answer is yes!  All you need to do is to place your ring on a ruler and measure the distance, or internal diameter, in millimeters from the inside walls of your most favorite fitting ring.  Simple!  


Measuring Your Finger with Paper or String

You can measure your ring size using either string, floss, or by cutting a strip of paper approximately 1/4” wide and 4” long. Make the paper about 1/2” wide for a wider ring. 

Take one of these measurement tools and wrap it around the part of your finger where you want to wear the ring.  Mark where the string, floss or paper first overlaps with a pen. Then, line that up with a ruler and take down its length in millimeters.

With standard ring sizes, every half-size matches up to a 0.4 millimeter increment, starting with size 3 equaling 14 mm, size 3.5 equal to 14.4 mm, size 4 equal to 14.8 mm, and so on. Common ring sizes for women are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm). For men, the most common sizes are 10 (19.8 mm), 10.5 (20.2 mm), and 11 (20.6 mm).
