Irrespective of your finger size and your ring circumference, how a ring should fit is all about comfort. “Your wedding or engagement ring should fit your finger snug enough it does not fall away from your finger. The rings should also wear loose enough that it can, without much pulling resistance, slide and pass over your knuckles.

If there is one hefty task to lift when buying an engagement ring, it is doing the exact ring measurement before ordering a diamond wedding or gift ring for her.

Some people love to wear multiple rings. If you are love that multiple ring aesthetics, you must measure all the fingers for the rings.



How to size a ring accurately

When you plan to sit down and take measurement for a ring, you should consider eliminating errors. More importantly, when you ask a friend over the phone to pick you a gorgeous engagement ring from a jewelry store and send, you must provide accurate ring size.

Here is how to figure out ring size accurately.

1. Consider large knuckles

Common with chubby fingers, the big knuckles can ruin your engagement party if the ring does come down past the knuckles.
Except you want to be left with injury and bruises, don’t expect a tiny ring to enter a finger with fat knuckles.

To check your ring size accurately, you should make your final finger or ring measurement to be half a size bigger. If you get a ring based on the exact number you got for ring size, it can probably feel tight.

Adding an extra half a size to the ring or finger size would help it to slide over your knuckles easily into the right place, without resistance.

Your accurate finger size = measurement in mm + 0.5mm, or reading in inches + 0.5 inch

 


2. Measure ring size on several attempts

You have to take your ring or finger size measurements for about 3 to 5 times to ensure accuracy. Make sure that the plenty tries produce approximately the same readings.

If you measure your finger size up to five times using a flexible tape, sum all the readings and divide by five. That is your average finger size.

Your accurate finger size = sum of all the readings divided by the number of trials

 

3. Measure your knuckles and base of your finger

Another way how to tell your ring size accurately is to measure the circumference of the base of your finger and the circumference of your knuckle.

The diameters for these two sections of your finger significantly differ. The knuckle diameter and circumference are larger than the dimensions of the base of the same finger.

The true size of your finger is the average value between base size and knuckle size. What I mean is, you should choose a size that falls exactly in the middle of the base and knuckle measurements.

Your accurate finger size = size on finger base in mm + size of knuckles in mm, divided by 2

 

4. Check the weather of the day

You want to know calculate average finger width for your ring, take the finger thickness reading 3 times a day – morning, afternoon and evening. Average the ring size by dividing the three results by 3.

Here is the simple reason: your hand and finger size fluctuate depending on weather temperature. You might have noticed it, your fingers are swollen in hot weather, shrink and look too skinny in mornings and nights when it gets colder.

It is best to measure your fingers on a warm day, as opposed to very cold, winter-like days or extremely high temperatures.

Your accurate finger size = sum of reading in the morning, afternoon and night divided by 3

 

5. Compare with ring size chart

The standard ring sizes help most ring wearers make the right choices and it can also guide you to choose your or her perfectly fitting diamond wedding ring.

To ensure you are accurate, use the ring size chart. You have to compare your finger size measurement to the standard ring sizes. Contact our professionals to help if you can’t find your own ring size. Perhaps, you can place a special order from jewelry makers.

Step 2 : Mark where the string or the ends of the string overlap with a pencil.

Step 3 : Take off and stretch out the string along a ruler or tape.

Another simple but straightforward method how to measure your finger for a ring is by using a tape. A measuring tape like the one for a seamstress is more flexible.

There is no need for a string or paper ass before. Check the inches and the centimeter scale, and wrap the flexible measuring tape round your engagement or wedding finger.

How you measure the finger for ring may produce inaccurate result, on one trial. So if you expect to get accurate dimensions, adjust tape so that it feels too tight, or too loose.

However, if you are going to pass the tape over or across the knuckles, at least pull it tighter. The tape is scaled in inches and centimeters, so depending on your favorite unit, read the value where the ends of the tape overlap.

To know your correct ring size, compare the tape reading to the nearest measurement on the ring size chart.

How to find out ring size using an existing Ring

If you already have a ring, that is pretty easier. The ring will serve no purpose when you’ve gained overall body weight (due to COVID-19 lockdown), get pretty fat fingers, and your old ring has become or feels too small to fit.



How to find out ring size with a Caliper

If you are fortunate to have an old standard ring that fits comfortably, you can measure it yourself or bring it to the jeweler to use calipers. Actually, a caliper is the best measuring tool if you want to figure out your ring size using another ring you already have.

Before you find out ring size of an existing ring, make sure the ring already fits your finger snugly–not loose and not tight. The ring with a comfort fit is rounded on inside and a ring with standard fit is flat on the inside.

It requires a bit of math to determine a ring size with caliper and this method is the most accurate. This will same result only if you are measuring a comfortable fit ring and a standard fit ring.

 

Step 1: Measure outside diameter of ring

how to find outside diameter of a ring with calipers

Measure the outside diameter (OD) repeatedly to ensure you have the same reading. If they differ, measure the OD three times and divide their sum by 3.

For example, OD = 22.91+22.93+22.92 divided by 3 is 22.92mm

 


Step 2: Measure ring thickness

Measure the ring thickness (TH) three times on three different sides of the ring, and record the average.

For example, TH = 2.27+2.28+2.76 divided by 3 is 2.77mm

 

Step 3: Measure inside diameter of ring

Use the caliper to measure the inside diameter of the ring in millimeters. It is just as simple as inserting the other ends of the caliper and adjusting them to touch the inside of the ring. Turn the ring (like spinning it) by an angle, take another measurement and calculate the average.



Step 4: Accurate ring size calculation

Your average inside diameter of the ring should come close to the difference between the ring thickness and the outside diameter. If they are not the same, get the average of the measurement and the calculated size (OD –TH).

You have to compare your ring calculations with the ring measurement-conversion chart.

 

how to measure ring size with tape measure or ruler

Place a tape or a ruler over a ring you already own if it fits your finger comfortably. The ruler or tape should come straight across the inside of the ring from one edge to another.

Let the zero-mark of the tape or ruler be exactly on one edge and you extend the tape to another edge. Turn the ring flat, and repeat the same measurement 3-5 times and calculate the average.

Sometimes, rings don’t come exactly round-shaped even though it may not be visible. Accurate measurement of the diameters on multiple sides is necessary for precision.

This can reveal irregularly shaped wedding rings. Anyway, this method is how to measure ring size in cm or mm since the ruler or tape has both scales – millimeters and in centimeters.

When you get the diameter measurement in millimeters, compare it to the measurement conversion or ring size chart to choose the right ring size.

 

how to measure ring size with paper or string

If you choose to use a paper, ribbon, thread or a string, that is ok but you still need to have a ruler or tape nearby.

Step 1: Cut out a thin sheet of paper, ring or thread, and place it over a ring that fits your finger well. If you can precisely detect the middle of the ring, make sure the edge of the ribbon or paper just pass over it.

Step 2: Mark the sections of the paper or thread that indicate the inside of the ring. Of course, this technique is prone to many errors because you may not place the paper exactly across the center of the ring.

Custom ring sizer cost few dollars, although they are the most accurate way to figure out or determine ring size. The ring sizers are designed with estimated size, width and fit for most rings.

Tips when measuring an engagement or wedding ring size

Fingers on the dominant hands are often slightly larger than on the less dominant hand.

Measure your finger later in the day when finger looks chubby. Finger looks thinner at night and in the morning. The best way is to measure the finger in the morning, afternoon and at night and get the average.

The ring size and any other measuring item should slip over your buckle with ease

It takes time to measure ring size accurately

Plastic ring sizers can be more accurate and reliable than paper ring sizers

Measure only the particular finger that will wear the ring and nothing else

There are vast differences in finger shapes.–your finger shape is as unique as you

If you are using paper ring sizers, know that printers have settings for margins that can change with each print size width. If your printer has larger margins set up, your ring size measurement will be affected as the measurement on the strip will get larger and bigger.


What Should I Do If My Ring Is Too Big or Too Small?

Now you know how to find your ring size. With everything done right, you can probably still have your ring too big or too small to fit your hand. In that case, you need to have your ring resized.

It is either you made a mistake picking the correct size ring, or you just received a surprised engagement ring or a family heirloom ring that does not fit you correctly. Another big reason is that you have probably gained weight and your fingers got bigger to fit your ring.

Above all, an improperly fitting or loose wedding or engagement ring has a bigger chance of falling off and getting lost. So you must do something to wear it properly.

The best skilled person to resize your ring is a professional jeweler. You know, you can’t just throw away a precious ring, so you must send it for standard service for ring resizing.

 

How do you resize rings – sizing up or sizing down?

First, Can You Resize a ring? Yes. Probably your ring is made of a non-metals like wood, quarts and metals like silver, gold or platinum. Some rings can be resized, others cannot. 

Rings can be resized, depending on many things, but heating up and cutting the band. First, if the ring is smaller and tight-fitting, an expert can resize up to make it bigger.

A jeweler can make the ring larger by either stretching the metal or extending it by soldering with another short metal. Unfortunately, enlarging a ring to half size bigger can make the ring weaker.

In the same manner, a jeweler can heat up your oversized ring and cut off a small piece of metal from the band. This will reduce your ring circumference and make it smaller. If it can’t be resized, a jeweler can install sizing assistant to anchor a top-heavy ring to your finger.

At the end of it, after soldering the ends, most jewelers will clean and polish your gorgeous ring to maintain the aesthetics and glittering appearance.

  • Rings with a simpler design are the easiest to resize
  • If the ring can’t be resized, larger or smaller, you can wear it on a different finger
  • Rings with gemstones around the entire band cannot have the size altered. Any attempt may compromise the tensile strength of the ring or cause the gemstone to mis-align.
  • Some metals are just too hard to cut, so a tungsten ring is too hard to cut or be weltered together
  • Rose gold rings and other variations of gold rings can break or crack when resized

The cost of resizing a ring varies. It depends on the work to be done on it by a knowledgeable and skilled jeweler. The engravings on the ring, and handling of the delicate gemstone is huge time consuming. All these can range from $20 per simple ring resizing to several hundred dollars for complicated and hard to resized rings.
