How To Measure Ring Size At Home

Measuring your ring size is a lot trickier as it sounds. Your finger fluctuates in size from day to day and season to season. Warm weather makes them plumper. Pizza night or sodium loaded burrito will temporarily swell them up. A dip in the pool will string them down. Your finger size is not constant, and it depends on what you are doing on a daily basis and what kind of environment you are in.

You will want the ring you purchase to fit you well according to your comfort.

So how to measure ring size at home with confidence? Here are the three simple methods which you can follow to get your ring size:

1. Measure a ring diameter

If you have a ring you are wearing and you want to buy another one of the same sizes, then you can simply measure its diameter with a ruler.

The simplest way to do so is to place a ring on a piece of paper, circle it inside, and measure the diameter (two opposite points through the center of the circle). When you obtain the length of the inner diameter, multiple it by the Pi number (3.14), and you will get the circumference.

When using this method to measure ring size at home, you should keep in mind that rings with a wide shank sit more tightly on a finger than thin ones. Therefore, their circumferences should be slightly larger than that of their skinny counterparts. When you buy these rings with a shank of around 3mm, then there is no need to size up.

2. Thread, measuring tape or strip of paper or floss

`Dr. Aragona from Prescription Doctor suggests that the most common method is to tie something around your finger – either a piece of string or floss – and then you must measure its diameter in millimeters. A ring size 3 is 14mm, and each size up from that is an additional 0.4mm. For example, a ring size 3.5 is 14.4mm. This method is not completely accurate though, so it may be best to buy a ring sizer. They are usually quite cheap online. They are like a zip tie that you tighten around the finger to get a perfect size.

One of the easiest ways to measure ring size at home is to use a piece of dental floss says Albert Reyes, founder of Home Living Lab. Dental floss is readily available in our homes and it does not cost much to take a piece out to measure your ring size. Simply wrap it around your finger and measure it against the ruler. Fast and accurate. After you are done measuring, you can use it to floss as well. No wastage!

Please make sure that you need to fit out the same finger on the same hand you are going to rock your ring on. Because all fingers are different and the dominant hand tends to have a slightly larger size, if you measure a different finger, a ring may not fit.

So, for that, you need to make a thread or a strip of paper, wrap it around your finger, and cut off the ends or mark them with a paper. Then, measure the piece you have got with a ruler.

This method has a right chance of error since any ring, unlike a thread or strip of paper, has a certain thickness. Rings of paper, metal, and thread are completely different things. A thread may get too deep into the skin while, on the other hand, paper vice versa might be too loose.

3. Multiple measuring

The previous method is pretty simple because we have access to our own fingers. Moreover, to minimize the errors, wrap a thread or paper around your finger five times. Then, measure the length of the piece and divide the sum of values by 5. Thus, your measurements will be more exact.

How to secretly measure a ring size?

If you want to purchase an Engagement Ring as a gift for your girlfriend, then you have a tough task ahead! You could take her pre-existing ring in a witty way and just slip it in your finger.

How are rings resized?

Following are the processes to resize a ring-

Cutting the Ring

The first thing that needs to be done when resizing a ring, whether it is being tightened, is to cut the metal. An incision is made so that the jeweler can work with the metal and extend the ring or shorten it from both ends of the cut metal.

Heating the Metal

Next, the jeweler heats the metal, which demands a great deal of expertise and precision. The temperature cannot be too hot or cold, as a cold temperature would result in having difficulty working with the metal, while a hot temperature could change the chemical properties of the metal. Without the necessary knowledge, heating the metal can cause irreversible damage to the metal and the ring as a whole. So, moreover, you must never allow inexperienced individuals to resize your ring.

Reshaping the Ring

When the metal is heated, the jeweler manipulates it with his hands and tools so that it is wider or narrower, thinner, or thicker than the original ring, depending on your requirements.

Once your ring has been resized, the jeweler will polish it so that it looks just as beautiful as it did when it was first made.

Though resizing may sound simple enough, it is truly a complex ordeal, which requires a great deal of patience and talent. Moreover, though many rings can be resized, some rings, such as those with stones all around it cannot be resized or would require a process that is very complex. In such cases, one can either upgrade the ring altogether or have the stones reset into a new setting with the correct ring size. Regardless it is imperative for your jewelry to be the correct size for you so that you can enjoy it properly and wears it with peace of mind.

Q1. How do I figure out my girlfriend’s ring size without telling her? I need to give a surprise gift.

Ans. If you’re surprising her with a proposal or getting a gift, there are a few ways to find her ring size without ruining the surprise.

A great way to find out her ring size is to ask one of her friends. Friends occasionally have this insight! And, if the friend doesn’t know right away, she can be the one to ask (nonchalantly). Even better, ask the friend to take your girlfriend engagement ring shopping “for fun.” Have her get professionally sized and ask her friend to report back to you. It’s best to choose a friend who might have once had acting aspirations!

Slisha Kankariya CMO With Clarity suggests few methods.

Method 1: Simply ask her. If she knows that you are about to propose, you can still surprise her with the ring style and center stone and in the process, ensure that the ring is a perfect fit.

Method 2: Measure a ring she currently owns, by taking it to a local jewelry repair shop. They can quickly and easily tell you her ring size. However, ensure that the ring you’re measuring is worn on the ring finger.

Method 3: Take a string and measure the inside diameter of a ring that she wears on her ring finger. Or wrap it around her ring finger while she is sleeping. Measure the inside portion of the ring. Once you have determined the millimeter diameter, compare it to the sizing chart to find the right size.

Method 4: Enlist the help of a close friend or family member to try and get the information about her ring size. Just be sure that they’re not giving the surprise away. They can find out the size for you and let you know before you make your purchase.

Q2. What’s the average ring size? What is the most common ring size for a woman?

Ans. The average ring sizes are 8. For women, the most common sizes are 9.

Q3. Does your ring size change when you gain weight?

Ans. Unfortunately: there’s no way to predict how your fingers will be affected by even a small amount of weight change. We recommend keeping an eye on how your rings fit throughout your weight gain journey.

Q4. How do you measure your ring size in inches?

Ans. If you want to measure your ring size in inches, you can follow the below approach:

a) Cut a thin strip of paper.

b)Wrap the paper around your finger. Make sure the paper is below the joint of your finger and close to your knuckle.

c) Mark the spot where the paper meets and measure the distance with your ruler.

d) Use the following chart to determine your ring size. Rings also come in half sizes, the measurements of which, of course, will fall somewhere in between the whole sizes.
