Want to get a ring for yourself or your loved one? It's not as easy as you would think. For one, do you know the size you need?

To know what's right, you need to look at the diameter of the finger. Measure the width of the forefinger, before buying it, as it can help you get the exact ring size diameter.

Also, before measuring the finger, know that:

  • Be wary of inflammation. Don't measure your finger if you've a swollen finger
  • You need to be at room temperature.

There are several techniques to measure the finger, to manufacture the ring and determine the size of it. While many use finger-sizing gauges to know the right size, it's not the only way. You can know your ring size in your home by using some simple techniques. Regardless of which method you use, don't forget to consider other factors such as the material of the ring.

Your Ring Size Can Change With Many Elements

When manufacturing rings, the material of production is a factor to consider. Hard metals such as titanium are hard metals do not alter in size regardless of environmental factors. Soft metals such as gold can change size a little if subjected to temperatures.

Metals such as iron, on the other hand, are deformed and corroded by oxidation, deforming the dimension of the ring. In the case of silver, it is a malleable metal, easily disfigured by alterations in the environment.

The temperature affects several metals, varying the ring size diameter significantly. In the case of cold, the metals tend to contract and at high temperatures they expand. In these the most vulnerable are silver, steel, gold, copper alloys, among others.

Preparing Before Measuring Your Ring Size.

Measuring the finger helps avoid getting the wrong size. However, you need to follow a few simple tips for the process to be one hundred percent reliable. The first is the temperature of the finger at the time of measuring. The temperature causes the finger to swell or thin, depending on whether it is hot or cold.

The finger should be its standard size, and it cannot be affected by swelling from blows. The forefinger also may not have a rash or any rash that can affect the measurement of the width of the finger.

In other cases, whether due to diet, malnutrition, or disease, the size of the finger shrinks. It is essential first to recover the mass lost by some of the situations raised before measuring the finger.

Can You Resize Rings?

There are cases where the person wants to change the ring size diameter, either by deformation or mis-measurement. In some cases, it is possible to change the size of the collar to the desired diameter. The first factor to consider is the manufacturing material of the ring; there are metals such as titanium that cannot be modified.

Another factor is the engraving and decorations that may embed in the metal. Sometimes the ring is engraved with dedication, and the modification process can permanently damage it. In the case of embedded jewelry, it can hurt when trying to change the diameter of the ring.

If the ring does not contain the descriptions described, you can change the size of the ring. You can go to a goldsmith or a specialist, and they will reduce or widen the diameter of the ring.

I Can't Resize My Ring, Now What?

At times, it is impossible to readjust the size of the ring; the question is what we can do. The truth is there are very few alternatives; the first is to transform the jewel into a different one. You want to change the gem; the first option is to melt the material to use it to produce necklaces or earrings.

Another way to reuse the rings is to create new ones of better quality. In some cases they develop alloys with several rings, creating a more resistant and striking material. In the fact that the piece has incrustations, they are reused to make necklaces and earrings.

The last option is to change the owner's ring, whether the ring was for you or someone else. Ask the goldsmith to make you another ring with the desired specifications and give the other to a person who serves him.

So, How Can You Measure Your Ring Size?

To measure the ring to the finger, think about the following. The first is the scales of the graph of the ring sizes in mm; this shows the different categories by finger size. Some goldsmiths use the ring size in mm, which is the US ring size chart measurement system.

The graph of the ring size chart apart from setting a standard in classification can also guide. The wire gauge size chart also serves as a guide for measuring finger size and establishing an approximate ring size in mm. It allows the goldsmith to have an idea of the size of the ring, and to know the most appropriate method of measurement.

There are different scales of graphs to measure rings. T the standard is the US ring size chart. The system characterizes by calibrating the ring sizes in mm, as a unit of measurement. It then measures the width and length of the wire gauge to mm, allowing a more precise measurement of the finger size.

Another system is the European one characterized by calibrating the ring chart in cm, not in mm. The diameter of the finger is measured in cm, causing the measurement to be less accurate and useful.

The graph of the US ring size chart is essential; however, there are other tools and measurement methods.

  • Using A Ring Sizer.

One of the most used tools is the ring sizer. It allows measuring the size of the finger, with several templates, which can either be metal or paper, depending on the manufacturer. Each piece has a specific size. The collection contains twelve to sixteen pieces with ring models that let mm to gauge.

The metallic pieces are models, which the customer tests to determine the most comfortable for himself. It examines with the closest measurements established by the wire gauge size chart.

In the case of the paper game, there are several templates with different sizes wire gauge to mm, which customers place on the finger. The paper measures the size of the forefinger and allows you to calibrate on the scale of the ring chart for better manufacturing.

  • Using String.

Using traces or chains to calibrate the ring size is very common and an easy process to use. For this, there are several methods or techniques using hints that allow you to calculate the size of the finger. The most common is a homemade method using a marker and paper, marking the diameter of the finger on the sheet.

Another way to make strokes is with the whole finger; usually, only the diameter measure, but this is the entire finger. The technique consists of wrapping a trace of paper around the finger, adjusting it as much as possible to it. The next step is to mark the trail from beginning to end to establish the length of the circumference.

As you can see, it is a method that calculates without measuring the size in mm, it base on traces of samples that reused from the mold.

  • Using A Paper Strip.

Paper strips are very commonly used to measure the size of the finger for the ring. There are several ways to measure it using pieces of paper, the most common being using blank strips. The simple technique involves wrapping half of the finger and marking the beginning and end to delimit the diameter of the ring.

The method is prevalent its implementation by people who want to give a ring. It is a highly effective homemade method and is very common in marriage petitions.

Another way to make it more specialized and professional are strips with the measurements of the ring size diagram. The pieces have different sizes; the client tries several until he finds the right one. It is a way to calibrate in mm the width of the diameter of the ring and to obtain the exact dimensions of the same one.

  • Going To A Jeweler.

Going to the jewelry store is the safest way to obtain the size of your ring since you will have a professional in the subject. The first thing is that you will be able to test the ring personally and wire gauge to mm exact of ring diameter. It's like going to a store to buy shoes, you liked it, you tried them on your size, and you purchased it.

If you don't find one with your tastes and preferences, you can have it made. Jewellers have their measurement tools like a kit of ring models, where they can measure the width of your finger. Another quality is their experience; they know how metals react to temperature changes and adapt to it.

Another advantage of a professional jeweler is the guarantee of the work; you can ask for a warranty if the size of the ring is not adequate.

  • Using A Soap Bar.

Using a ring reference is a logical way to go about it. However, what if you cannot use the ring? Whether it's a surprise gift to a particular person or a gift to a stranger, you need the measurement. A bar of soap can help you to get the dimensions of the ring without so much effort.

The technique is simple, wet a bar of soap and press the ring on its surface. Squeezing the ring will leave a mark, where you will have the dimensions of the ring without having to wear it. It is important to emphasize that you must measure without moving the ring laterally because you will damage the measurement.

This form is not professional. It is also important to point out that you will not be able to use the bar of soap until you have given the sample to the jeweler. The soap can wear away and erase the ring size sample.

  • Using A Ring, You Already Have for Reference.

Another way mm to gauge the size of the ring to be manufactured is with another reference ring. You can use an old ring to show the size of the desired jewel without having to measure your finger. It is also important to note that the reference ring must be well adapted to the thickness of your finger.

In some cases, whether due to weight loss or gain, the diameter of the finger varies and the ring loses relevance. We see cases where the ring is small or large because the reference ring was not left to the person either.

Another point to consider in the ring is its constitution; it is not advisable to use those that are deformed. The deformation can prevent to calibrate the diameter in mm of the new ring and to be able to make an active duplication.

You're Looking For A Surprise, So What Can You Do?

You want to give a surprise with a ring. Take the sample and go incognito. Here are some techniques to get the ring reference you want, without letting your loved one know.

  • Ask For Help From A Confidant.

The first way is to ask another trusted person, who is close to the receiver of the ring. You can ask them to find out the information without looking suspicious or complicit in the surprise. In the case of women, the best way is to ask a friend of hers for a favor. It is usual for women to measure the size of their rings and other jewelry stores.

Another way is to ask that other person to take a sample of some ring she has. You can request a brother-in-law or mother-in-law to take it without her noticing the width of any ring. It will guarantee you to have the sample of the ring, either in physical or in a bar of soap without raising suspicion.

  • Borrowing Another Ring.

Borrowing another ring without asking is a good option. You can use old rings to make a new one. It's common for both sexes to have rings they don't use either because they don't like it or they forgot it. It's an advantage since we can take it as a reference to make a new one and they will never notice.

Use the earlier ring as a reference for the real present to create an unforgettable moment.

Another way is to ask someone else to take it for you, a relative who is your accomplice and then return it unseen.

  • Comparing Finger Sizes.

Comparing finger size is an implicit way to find out the size of a finger without raising suspicion. You can buy a sample kit with the excuse that it's for you and invite her to measure the ring. You will be able to get her ring measurement through a typical situation without raising suspicion.

Another way is to compare rings; you can use your rings and propose comparing them with hers. You can provoke a conversation with the subject and ask her to measure the size of the rings without raising suspicion.

Another way is to ask her to measure her fingers; you can use paper strips or another measuring tool. With this, you will have the measurement of her finger either the diameter or the circumference of the finger.

Additional Ring Size Measuring Tips.

  • Take Note Of The Temperature.

An essential element in measuring finger size is the temperature of the finger. The temperature can vary the dimensions of the finger by dilating and contracting. It is important to note what temperature you had at the time of calibrating, to anticipate a significant change in the measurements.

You can use a thermometer or take note of the environment to which your hand was exposed before taking the measurement. In hot temperatures, they tend to increase in size due to the thermal dilatation characteristic of this. In the case of a cold, the finger decreases the dimensions by thermal contraction, the lower, the higher the shrinkage.

Ideally, the measurement should be at room temperature, to have the standard measurement of the finger. If you can keep track of the three cases is better, you can have the size of your finger and adjust your ring to these.

  • Measure Your Fingers Several Times.

Measuring a finger once can be insufficient, as you may have an inadequate or wrong calibration. The first reason is that the tool can't be adequate or you don't have the experience of its implementation. Another reason is that it will allow you to make sure the size is right; otherwise, the ring will get the wrong dimensions.

Another tip is to take measurements with different tools; you can use ring models. Then you can use strips of paper to measure the diameter of your finger and compare it to the diagram of the ring size.

Take notes of each measurement and take it to the jeweler so that he can determine the recommended size of the ring. Doing this will ensure greater accuracy and fit the ring better.

  • Think About Ring Type.

Think about what type of diamond you will want, to determine the size and make adjustments. For example, take into account that blows can deform soft metals such as gold or silver. Another reason is that these metals can be distorted, but also modified at any time desired.

In the case of heavy or hard metals such as platinum or titanium are durable but impossible to modify. Their high density makes them malleable and does not alter their consistency at any time.

In the case of incrustations must be taken into account, since some people also incrust inside the ring. The incrustations can occupy a significant space that should consider at the time of making the ring. Another factor to consider is the density of the materials, and the damage it can do to the skin of the user.

  • Don't Forget About Knuckles.

You can't forget your knuckles when measuring your fingers. Most people only measure the base of the finger as it is the area that will occupy the ring. The knuckle area is the most extensive area of the forefinger and can cause the finger not to go beyond this area. It is why you should measure both the base and the knuckle area.

This characteristic is more important in the case of men. Women tend to have thin knuckles, and the variations are not as marked and can pass without a problem. Men tend to have more pronounced fingers, which mean that the rings do not move quickly.

Measure the different zones of the finger to know that the dimensions pass along this one.

  • It's Better To Buy A Ring That's "Too Large" Instead of "Too Small".

It is indeed better to buy a ring with exact measurements, but sometimes this is not possible. Either because we can't get the precise measurements for any of the tools mentioned. In that case, it is better to buy a ring with larger dimensions, to make sure it fits your finger.

A ring that you cannot use is more useless than a car without rubbers; the ring is to show off and be shown to the public. A small ring that does not fit on the finger is surely not a worthwhile purchase. If in doubt, go for a size larger.

Everyone loves a good ring, whether it be for a special event or just to look good. Why not ensure that you pick the right one?
