How to determine ring size: correspondence between Chinese, European and Russian sizes

Whether you choose the right ring size directly determines how comfortable it will be to wear. Will the ring bring pleasure or become an unnecessary irritant? A narrow ring is, at a minimum, a constant discomfort, a wide ring dangles on your finger, quickly gets scratched and loses its appearance, you just want to take it off and put it somewhere.

With the development of high technologies, life has become much easier and many problems have been solved. But as often happens, solving old problems often creates new ones. And indeed, with what, and with the sizes of the rings, there were never any difficulties. You go to the store, choose a ring, try it on, and the size, by and large, doesn’t matter. Many did not even bother themselves with such difficulties. Unless buying a ring as a gift meant certain difficulties.

But what if the ring is ordered via the Internet, and even in another country? And returning goods sometimes involves certain difficulties. Then all that remains is to accurately determine your ring size and, if necessary, convert it to the size of the country where the order is made.

The procedure for determining the size is simple, but, at the same time, responsible, and it is worth approaching it seriously, unless you intend, of course, not to bomb the search engine with queries “how to narrow (expand, sell) a ring.” Even if a jeweler can help you in case of problems with the size by slightly narrowing or widening the ring, he still can’t always do this without losing the proportions and appearance of the product.

How to determine the ring size? If you don’t have a jewelry measuring instrument at hand, such as a ring gauge or a finger gauge, then it doesn’t matter. You can figure out how to determine the size both in the store and at home. There are several ways to do this.

Types of sizes

The most popular types in our country are Russian, Chinese and American. When purchasing a product in an online store, please note that sellers usually provide size charts. It is enough to know the size according to the Russian system and compare it with tabular data. Russian

According to Russian standards, the ring size is equal to its internal diameter. In this case, rounding up or down is allowed.

Chinese

China uses the centimeter measurement system, so there will be no need to convert anthropometric measurements. The size is calculated mainly according to the American method.

When ordering jewelry from a large Chinese online store, for example, Aliexpress, please note that if the ring size is not indicated according to Russian standards, there must be a size conversion table. To clarify the size, you can always contact the seller of the product.

American

To bring the ring size, which is indicated according to the American system, into line with Russian standards, you can apply the following formula: USA = 1.2 x ROS - 13.8, i.e.

Russian size will be = (US +13.8) /1.2.

For example, the size on the ring is 6, we substitute it into the formula: (6+13.8) /1.2=16.5.

International tables for men's and women's rings

The Russian table of sizes for men's and women's rings is compared with the European one on the basis of a mathematical relationship between size indicators. The value is determined by exact calculation. With European rings the situation is simpler than with American and Japanese ones. In Russia, the size of the ring is determined by the internal diameter, in Europe - by the circumference.

To understand which European ring sizes correspond to Russian ones, you need to measure the internal diameter of the jewelry and multiply it by 3.14 (“pi”). If the reverse comparison is carried out, i.e. If you need to find out the Russian size corresponding to the European one, then the first one must be divided by 3.14.

Formulas for determining numbers that will correspond to foreign indicators:

• American = (Russian – 11.5):0.83.
• Japanese = (Russian + 12.67)*3.
• English = (Russian – 11.5):0.4.

Size relationship between different measurement systems

The table below shows the relationships between different measurement systems:

For example, if your size is 16.5 according to the Chinese and American system, it will be equal to 6.

Features of determining ring size

The methods for determining ring size are the same, regardless of the person’s gender. Features are expressed in sizes, which depend on the configuration and age.

For women

You can simply use any of the proposed methods. You can find out the size either using the ring the girl has or use extraordinary options.

For men

For men, wide joints can be a problem, so you will need to buy a ring a size larger, even though it will fit loosely on your finger.

For children

Children need to most accurately calculate the size of the ring so that it does not fly off the hand, but also does not put pressure on the finger. Children grow quickly, so when purchasing expensive jewelry, you need to understand that you won’t be able to buy it “for growth.”

Life hack: determine the size using your fingers

The method is suitable for those who do not know how to discreetly pick up a ring for a girl without knowing the size of her ring finger. This secret method is often used by guys who are planning to propose to their beloved. Ask her for one of the rings, “just try it on.” Place the jewelry on your finger and remember where the ring fits most comfortably. While your memory is fresh, run to the jeweler and ask him to measure the diameter of the marked area. Done, you are amazing!

Finding your ring size using your fingers

Keep in mind that on average, the smallest ring size for women is 14, and the largest is 22. Therefore, if your value suddenly turns out to be much smaller or larger, perhaps you made a mistake somewhere - try to calculate the required diameter again.

What to consider when determining size

The circumference of a person's fingers is not a constant value; it depends on many factors that must be taken into account to correctly determine the ring size.

Weather conditions and time of day

If it’s hot outside, your fingers swell; in the cold, the process is reversed - they will be smaller than their standard size. The same applies to morning measurements, when the overnight swelling has not yet passed.

Decoration design and width

Large, wide rings with additional decorations should be easily removed from the hand. Experts recommend that if the ring width is more than 4 or 5 mm, add 0.1 mm of its size for each subsequent one mm of ring width. For example, a ring 9 mm wide with a finger size of 16.5 needs to increase the ring size by 0.4 mm and get a size of 16.9, rounded to 17.0.

For thin people, it is allowed for the ring to fit more tightly on the finger.

Physical condition of a person

A change in finger volume can occur after active physical activity or training. If there was a wild party the day before, it is better to wait to take measurements until the next day. You can’t measure immediately after you’ve carried something heavy; you need to let your fingers relax.

A change in the size of the fingers can occur as a result of a disease characterized by swelling: disease of the kidneys, heart, blood vessels.

Measured arm

The ring can be designed to be worn on any finger of the left or right hand. There are special jewelry for thumbs or little fingers, the size of which is larger or smaller, respectively.

Regardless of which finger the jewelry is intended for, it is better to measure the size on the fingers of both hands and choose the largest value.

What is finger size?

Let's start by studying the hardware: what is finger size and why do you need to know it? Take any ring of yours; draw an imaginary line from one edge to the other - in other words, measure the diameter. For greater accuracy, all measurements are taken in millimeters. The resulting result is the parameter you need. Knowing these numbers, you can easily select a suitable gift and calculate the size.

Jewelry ring sizes

As a rule, the gradation step in sizes is 0.5 mm - in jewelry stores you will see sizes 16, then 16.5, then 17 and so on. Now that we understand the terminology and technical nuances, let's talk about how to find out your ring size.

Popular ways to determine ring size at home

There are several ways to determine the ring size for your hand or the hand of another person.

You can find out the size even if you want to surprise a loved one so that he doesn’t have to guess about it.

Using thread

Procedure:

• take a strong thread, preferably twine;
• wrap your finger, do it lightly and apply pressure;
• cut to the required length;
• take a ruler and measure the length in mm;
• using the formula: Circumference/3.14, calculate the diameter using a calculator;
• this will be the size of your decoration.

If the thread is thin, wrap your finger several times to make it easier to measure the size.

If you do not use a calculator, you can get the data from the table below. Just round the result to the given values.

Using pen and paper

The measurement is carried out in the same way as using thread, only we use a piece of paper instead. Mark the required length with a pen, then measure the length. This method is more accurate, because you can choose any width of the segment and it will be more convenient to try it on.

Using a measuring tape

You can use the following measuring tape template:

It needs to be printed and cut out, then cut in the indicated place. After inserting the sharp end into the slot, place the paper ring on your finger and measure it.

With the help of friends

If you want to make a surprise, you can ask friends or relatives for help. But this method will not be accurate; rarely does anyone know the ring size of even a loved one, especially since it changes throughout life.

In addition, not all loved ones can keep other people's secrets and the surprise may be ruined.

According to existing decoration

If you have a ring that is exactly the right size, measure its diameter on the inside and round up accordingly.

How to take a measurement:

• place the ring on a clean sheet of paper;
• carefully circle the inside of the circle several times;
• measure the diameter of the resulting circle in millimeters;
• You can compare the size with the picture below.

According to clothing size

The size of our fingers, of course, depends on the size of our clothes, but this connection is very approximate. There are people who wear plus size with thin fingers and vice versa.

Therefore, this method will allow you to determine the size only if you first pay attention to whether the lady’s (or young man’s) fingers correspond to their overall sizes.

If you do not notice any significant deviations, use the following table:

other methods

You can find a lot of lifehacks on the Internet that offer different ways to measure ring size.

In our opinion, the most productive:

• To measure your partner's finger and avoid making a mistake, do it while she is sleeping.
• Take the ring the person is wearing and take it to a jewelry store. This way you will get the exact size, the main thing is that you won’t miss any.
• If you can’t take the decoration out of the house, trace its inner circumference and take the drawing to the master. It will help you determine the size accurately.
• Bring the jewelry maker a photograph of the girl, preferably one with her hand visible. A specialist will be able to determine the size immediately from the photograph. You won’t be able to get an accurate result on your own this way.
• Place the girl's ring on your little finger and draw a circle where it stops, or just remember this place. A jeweler will be able to determine the exact size by visually examining your pinky finger.

How to take your measurements

If you don’t know the girth of your finger, here are some proven tips to help:

• Take a cotton thread and wrap it around your finger so that it fits snugly against the skin, but does not press. Mark the points of contact with a felt-tip pen, and then measure the distance between them. Divide the resulting number by 3.14.

• You can find it in jewelry stores or here

  
  . In the second case, you will have to try to print it in full size. Then the strip should be cut out and a cut should be made at the place where it is marked. After this, insert one end into this cut and tighten the ruler on your finger. At which number the strip is fixed, this will be the size of the ring.

These two methods are quite accurate and will help you buy the optimal size jewelry.

How to round the result to get the correct size

When measuring the circumference of a finger, the result may not be whole. More often you get uneven numbers: 15.76, 16.43. When rounding, pay attention to the thickness of the decoration. If the ring is up to 5 mm wide and narrower, it is better to round down, for example, from 15.23 or 15.12 to 15. With a wide decoration, it is better to round up, for example, instead of 15.6 it will be 16.0. The margin must be at least 0.5 mm.

Be sure to consider how often your fingers are swollen. In some cases, it is better to purchase a ring 0.5 size larger.

When is the best time to measure your finger?

Take three measurements: in the morning, at lunch and in the evening. During the day, the finger may swell, which must be taken into account when choosing jewelry. It is important that it does not sting or cause discomfort even if the fingers are swollen.

The most favorable time to determine the ring size according to the circumference of your finger is the middle of the day. It is during this period that a person is at the peak of his activity, and the water-salt balance of the body is optimal. The room must have a comfortable temperature; heat or cold is unacceptable.

Additional tips:

• You should not take measurements after sports training or on a hot day.
• For greatest accuracy, measure several days in a row.
• Round the resulting values ​​correctly. If the product is up to 5-7 mm thick, then round up (for example, 14.9 is 15 rubles). But if you choose a massive ring, it’s worth including a “margin” of 0.5 mm.
• You should not take measurements after drinking a lot of liquid, or during illness.
• Your left hand is slightly smaller than your right, so take measurements on the hand on which you plan to wear the jewelry.
• To make the jewelry easy to put on and take off, when measuring, take into account the “bone” of the phalanx.

Ring size charts

Below are standard tables for determining ring size depending on the size of your finger circumference.

For women

Sizes considered here are in the range 15.0–19.0.

For men

For men, sizes range from 18.5–22.0:

Additional recommendations

There are a few important things to keep in mind when measuring your fingers.

Firstly, for the most accurate results, it is ideal to measure your finger three times: morning, afternoon and evening. Depending on the time of day, your hands may swell or swell, so you need to choose a ring that will not pinch even with swollen fingers. You should not measure your fingers on hot days or after active sports. Take measurements several times and on different days - if at least two values ​​are similar to each other, then you have found the exact size.

Secondly, it is important to know the thickness of the gift ring. If it is thin (up to 7mm), round the value obtained during measurements to the nearest one. For example, if during your measurements you get a value of 15.8, then the required size will be 16. If the ring is thicker than 7mm, it is worth making a reserve of 0.5mm. With the same value of 15.8, it would be better to choose size 16.5.

Jewelers' recommendations

Jewelry craftsmen adhere to precision in determining sizes, so they advise turning to specialists.

What recommendations do professionals give:

• Roll up a small roll of paper and insert it into the girl's ring, winding the roll until the ring sits securely on it. Staple the resulting scroll and go with it to the store to select decorations.
• Do not buy expensive jewelry “by eye.” You may not only not get the size, but also not satisfy the desire of the person for whom it is intended. He may not like the design or execution of the ring. Therefore, it is better to coordinate an expensive purchase.
• If you do not know the exact size, then it is better not to buy a ring with stones or moving elements, because if you have to reduce it, the stones and additional jewelry may be damaged.
• Engrave only if you know the exact size of the item. Otherwise, it will deteriorate when the jewelry increases or decreases.

How to choose a measuring time so as not to make a mistake with the size

Depending on the time of day when the finger size is measured, the indicators can vary greatly. On average, the error may be 0.5 sizes. We recommend taking measurements in the middle of the day. This is the optimal period when optimal balance is achieved in the body.

When it is not recommended to take measurements:

• during illness;
• early morning or late evening;
• after training;
• in excessive heat or cold;
• after drinking large quantities of water.
