Check out this quick diamond-buying cheat sheet.

Ring Sizes Measurement Considerations

A ring is a typical band worn on the fingers. Rings are made of metal and usually have one or more gemstones. People wear rings as an ornament to beautify themselves; some wear rings as a sign of authority, marriage, or engagement.

Point 1: the first point is to ensure you measure the exact finger you want to wear the rings in because our fingers are different

Do you know the sizes of your fingers are different? Yes, they are different because research and studies have shown a significant difference between the sizes of fingers.

To avoid mistakes or errors due to differences in finger size, measure the finger you want to wear the ring on.

Point 2; consider your knuckle size when taking measurement

Use the size between your knuckle and your finger if you have a finger with a smaller base size than your knuckle. This will allow the ring to move freely (but not too loosely) into your hands.

Point 3; measure your finger at the end of the day

This sounds awkward, right? Yes, it is, but it is the best time to take finger measurements.

This is because of the effect of temperature on the body. The body shrinks when the temperature is cold and expands when the body is hot. It is just a natural mechanism for regulating external temperature.

Our finger sizes are always smaller in the morning because our body is cold and large later in the day when the body is warm.

Point 4; repeat measuring the ring size more than once to get an accurate value.

The aim of measuring finger sizes is to get rings that fit snugly on your finger. A ring should slide into your finger with ease, but it should not be above to fall or come off easily.

A properly sized ring should not put too much pressure on the hand, and it should not be able to fall off easily.

Repeating the process will minimize the risk of getting a ring that won't size you perfectly. It will also help you get the right fit ring that will prevent you from wasting time searching for how to resize the oversized ring or purchase another ring.

Point 5; know the type of ring you will be buying

If you buy normal-sized rings, any measurement you take will work perfectly, but if you are considering buying a thick or wide ring, you need to add an allowance to the ring size. The allowance for the ring size can be an addition of 0.2-0.5.

This simply means if your ring size is 6.0, you must add 0.2-0.5 to the size, resulting in a 6.2- 6.5.

Having discussed what you need to know before measuring ring size, let’s move to the body of the article, which explains how to measure ring sizes.

The methods that will be explained in this article will require the use of a ring-size table or chart.

First Measuring Method

THE FIRST METHOD TO MEASURE YOUR RING SIZE IS BY USING A STRIP OF PAPER

This is one of the easiest and simplest yet most effective and efficient ways to measure the size of your ring.

What do you need to figure out your ring size using this method?

  • This method requires you to have a pencil, pen, or marker to mark points when you measure
  • A ruler is also needed for you to figure out the length you will use to calculate the circumference

  • Lastly, you will need a strip of paper to be folded around the finger.

The process of measuring

  • To use this method, the first step is to cut a strip out of your paper. Ensure the strip of paper is about 100 millimeters in length.
  • The next step is to fold the thin strip of 100 millimeters at the base of your finger. Ensure the paper is folded close to your knuckle so you can have a perfect measurement.
  • Use the marker, pen, or pencil to mark where the end of the thin strip of paper meets.
  • Use your ruler to measure the length of the paper that was folded around your hand
  • Finally, you convert your measurement to your ring size and check the size of your ring in the table above.

Second Measuring Method

THE SECOND METHOD IS FOR YOU MAKE USE OF A STRING

What do you need to measure your ring size using this method;

  • This step requires you to have a pencil, pen, or marker to mark points when you measure.
  • A ruler is also needed to measure the length you will use to calculate the circumference.
  • Lastly, you will need a string that will be folded around the finger.

The process of measuring

  • Just like you had to cut a thin strip of paper, you will cut the string too, but the string should be about 6 inches long this time.
  • The next step is to fold the 6 inches of string at the base of your finger. Ensure the string is folded close to your knuckle so you can have perfect measurements.
  • Use a marker to mark where the string meets.
  • The measurement string should be placed on the ruler.
  • Record the point on the ruler where the string meets in millimeters.

Use the table above to check for your ring size.

Third Measuring Method

A RING THAT FITS YOU CAN COME IN HANDY TO HELP YOU DETERMINE YOUR RING SIZE

What do you need to measure your ring size using this method?

  • A ring that you have been wearing fits you perfectly.
  • A ruler to measure the diameter of the ring.

The process of measuring using this method

  • The internal diameter of the ring you have at home will be measured using a ruler.
  • What is the diameter of the ring? The diameter of the ring is the distance between two sides of the internal hole, excluding the metal.

Take down the diameter of the ring and use the table above to determine your ring size.

Fourth Measuring Method

This approach is like making use of a string. The only difference is the thread you would be using. This method is also easier because threads are easily assessable, and taking a measurement using threads is also easier.

What do you need to measure your ring size using the thread method?

  • This step requires you to have a pencil, pen, or marker to mark points when you measure.
  • A ruler is also needed to measure the length you will use to calculate the circumference.
  • Lastly, you will need a thread to be folded around the finger.

The process of measuring

  • Just like you had to cut a thin strip of paper and the string, you will cut the thread to about 6 inches.
  • The next step is to roll the 6 inches of thread at the base of your finger. Ensure the thread is folded close to your knuckle so you can have a perfect measurement.
  • Use a marker to mark where the thread meets.
  • The measurement string should be placed on the ruler.
  • Record the point on a ruler where the thread meets in millimeters.
  • Use the table above to check for your ring size.

You may be bothered by what happens to your ring when the size of your finger grows.

Because wedding rings are meant to be worn forever, you will be bothered by what happens to the ring when you outgrow the ring or when the finger shrinks due to physiological changes.

Resizing and shaping simple rings is easy and can be done by a jeweler but rings with wholesale loose diamonds band may not be possible to resize. Some diamond rings have set diamonds that will be displaced when metal work is done.

Other Common Methods

Another problem you may face is getting her the ring without her consent.

Marriage proposals or promise rings are always the best when they come as surprises. But the challenge is how to get the perfect ring size.

The following will help you.

Meet with her confidant

Meet her best friend or sister to help you with her ring size. They will help you with the measurements. Avoid asking more than one person because asking too many will allow her to get the news prematurely.

Use one of her Rings to get the Measurement

You can use one of her rings to measure if she has a jewelry collection, but if otherwise, be watchful of moments when she takes off her ring. Immediately she takes the ring off and quickly measures without her notice.


All you need to do is to trace the ring out on a piece of paper or press the ring in a bar of soap.

Use Your Brain

To do this, you need to be smart and creative. All you need is a thread, string, or paper to measure while caressing her or when she is sleeping.

Take her to the Jewelry Store

You may wonder why this is coming in when I said it is better that you surprise her. Be relaxed; the ring is not for her.

Just take her to the ring section, where you can get casual rings, and tell her you want to get one for your sister or mom. Allow her to test it on her fingers and be watchful of the ring that sizes her perfectly.

I am sure, at this point, you have gotten all the necessary details required to figure out the ring size.

You now understand the process of measuring ring sizes, what you need to know before you measure the ring size, and the tops that can make measuring the ring size very easy.
