Ring Size Guide & Most Common Ring Size

Avoid ordering the right ring in the wrong size. This guide covers how to measure your ring size, handy measuring tips and includes tools (ring sizers, ring size chart, and ring size conversion chart) so you can shop with confidence.


When buying a ring, it’s important to select one that fits comfortably. The ideal ring should have enough grip so that it doesn’t fall off by itself and still be loose enough to slide off with little to no effort. Before measuring your finger you need to keep in mind that its size changes depending on the time of day and the temperature of your surroundings.

The average ring size for women ranges from size 3 to 9, with 6 being the global average ring size. The average men’s ring size ranges from size 8 to 10, with size 10 being the average size in the U.S.

Measuring your size ring accurately is important and you’ll want to be sure you’re getting the right size before you order. There are several ways to find your ring size at home. All the best methods are outlined below.

  • Ring size may vary with temperature and time of day. It is best to measure your finger at the end of the day when your fingers are warm.
  • Take measurements several times to ensure accuracy. 
  • While the ring fit can be a matter of personal preference, we recommend selecting a ring with a size that is comfortable but requires slight force to slide over your finger. If a ring slides on and off too easily, it may fall off when your ring finger is at its smallest (when it’s cold, etc.).

Engagement rings are probably the most special jewelry purchases that most men will make. However, picking out a perfect engagement ring can be quite difficult because of varying women’s ring sizes if she has slender fingers or large knuckle size. Especially if you are hoping to make it an unforgettable surprise for your girlfriend. After all, this ring is a symbol of your undying love and commitment. So you want it to be a perfect fit, not just a rough estimate.

If you already have an idea of the design and style of the engagement ring you want from the jewelry store, here are some ideas on how to get your partner’s right ring size without her catching on. There have been some tales of getting a ballpark figure of one’s ring size by the shoe size, another based on average height and weight. There is more bearing, though, on using average height and weight to determine your ring size or get your finger sized and have your rings fit. Tall and heavy people usually have large knuckles. So, if your surprise proposal allows no time to get the size of her finger early, you can use the average woman ring size as your guide. With more time to prepare, here are some other methods to try.

Method 1 : Use a String

Try looping a piece of string around her finger while she’s sleeping. Just be sure it’s not wound too tightly. Once you’ve got it on right, make note of the meeting point of the string, then mark it with a pen or cut to the correct length. You may then use the ring sizer from our website to measure the exact finger size.

Use A String


Remember that her dominant hand will most likely be about a half size a little bigger than the other. If she’s right-handed, her ring finger on the left hand might be smaller in size.

Also, be sure to not make the knot too tight when using string to measure her finger. If this happens, the measurement you get may end up being smaller than her actual size. The string should be able to move gently over her knuckle. Also, when using a pen or a marker, make sure that the pen you use is finely tipped. If the ink bleeds, the markings will be too wide and you will end up having a highly inaccurate measurement. Even a half size change will make the ring measurement too small or too big.

Also keep in mind that rings are not as flexible as a string so even when this method is executed perfectly, it’s still less accurate than simply having her try a ring on. Errors of even half sizes could have you get the ring to be resized.

Method 2 : Trace a Ring She Owns

You can also check her jewelry box when she’s not looking. All you have to do is trace out her favorite ring on a piece of paper and bring it to an expert for accurate sizing. But be careful! She might own a ring that is meant to be worn on the thumb or pinky finger. And even a ring for her middle finger will most likely be at least a half size larger. If you happen to measure the wrong kind of ring, you will get a completely different size than the one she wears on her designated ring finger.

Trace A Ring She Owns

Method 3 : The Direct Approach

Alternatively, there is always the option of simply asking for her ring finger size and gifting her some fashion jewelry from an accessories store – this could make for an even bigger surprise when she receives her actual gift.

The Direct Approach

Method 4: The Subtle Approach

You can also ask her if she has a trusted jeweler. Most jewelers keep the sizes of their clients on file. You can tell her you need to buy some jewelry for your mom and would love to try her trusted providers. If she has jewelers she uses and trusts, not only can you find her ring size but you can also gain insight into her design preferences too.


For most of our customers, a tight-fitting ring is preferred. But how can you tell if a snug ring is in fact “too tight?” It may not seem important, but having an overly narrow ring may cut off circulation and leave your own finger feeling numb.

Is Your Ring Too Tight

One way to know whether your ring is too tight is by twisting it on your finger. If you can effortlessly turn it from side to side with little resistance, the size is just right. If your skin sticks to the metal and twisting the ring requires extra force, then it’s safe to say that your ring is too tight for your finger.

Alternatively, you can simply try taking off your ring. If you can remove it without a hitch, the ring fits you perfectly. If it remains stuck on your finger, even with thin fingers, it’s too tight. If you’re in a situation where you can’t slide your ring off, you can try icing your finger or dipping it in oil or butter. If it still doesn’t come off by itself you should immediately seek medical help.


No couple wants their wedding rings to fit too tightly, but you also don’t want them to be too loose. Rings are often quite costly, and losing one can be a nightmare! It’s even more devastating when you don’t realize it’s gone until hours later. A good ring must slide off your finger comfortably but not have too much mobility around the base of the finger that it can slide off without you knowing.

If the ring can slide off your finger without having to twist or pull or it’s so loose that it spins on your finger, you should have your ring resized immediately.


We Offer Free Resizing

ICONIC provides resizing for most engagement and wedding rings. Certain pieces, such as eternity rings and rings intricately designed by wedding band designers that are very ornate may not be eligible for a resizing. In such a case, a jeweler will have the right gadgets to get the perfect ring sizes for both men and women.

Resized or altered rings may not be returned. After getting it resized the first time, the ring will get weaker with each following resize from the manipulation. This will only make the ring more susceptible to tearing and damage, so we highly recommend adjusting ring sizes only once, for both men and women.

If you do decide to have your ring resized, make sure that you get an expert’s opinion on your size. 

We are always happy to help. Our team of jewellery experts will be delighted to assist you in getting the perfect fit for your engagement ring! We’re online daily via live chat, or you can simply send our team an email to inquire about ring sizes.

Average Ring Size for Women

The typical range of the average female ring size is between a size 5 and 7, although this can vary depending on the person’s height. We also know that the average-sized woman in America is about 5-feet 4 inches tall, so you can use these averages to get her finger dimensions without her knowledge. If she’s shorter or weighs more than just mentioned you can go up a size or two. You can get a rough estimate of the size of the ring based on height and weight then.

You might want her finger measured if you know she wears thin band rings frequently because anything bigger could cause pain from inflammation. The important thing is for the ring to fit comfortably!

Average Ring Size for Men

The average ring size for men or average finger size ranges from 8 – 14. The commonly purchased sizes in men’s rings are from 8-12. The average ring size men on the numeric scale is 10 in the US, which is around 19,8 millimetres inside circumference.

Men’s ring sizes also vary, like women’s ring sizes and how they are measured, as well, in different countries. Fortunately, there are conversion charts to guide you get the right size regardless of where the ring was sized. As mentioned above, there are a number of ways of ensuring the right fit for your partner’s ring size. If all else fails, you can ask him directly.

Frequently Asked Questions

A general rule is that you should spend at least 2 months’ salary on the engagement ring. For example, if someone makes $60K per year they could put down 10% of their annual income or 1/6th which equals about 500 dollars for an average price range in America today ($5-$10k).
According to The Knot 2020 Jewelry and Engagement Study, the average cost of an engagement ring is currently $5.500 USD which may be a restrictive factor for some couples. Considering how much to spend varies per couple, depending on factors such as their income or location in relation to other countries’ currencies rates at the time when purchase was planned, making any comparison difficult.
There are many factors that impact the cost of a diamond, but it’s most often determined by its Cut quality. A 1 carat stone will vary in price from about $1,800 to 12 grand depending on what you’re looking for and how much clarity or color is desired among other things like shape as well!
Rings can usually be resized up to two sizes either way. Any more than that and it’s too much stress on the rings which could cause them to bend or crack under pressure, so make sure you get a size suitable for your unique finger shape!
In the US, the average ring size for women is between a size 5 and a size 7, all of which are almost equally as common. You can also check out our size guide for women for more information.

To measure ring size at home, take a piece of string or dental floss and wrap it around the base of your finger or the finger of your partner to determine the ring size. Mark the meeting point of the string, then line that up with a ruler and note its length in millimeters. You may use a ring sizer from our website to check your finger size.
Rings for men come in a variety of sizes, with the average ring sizes being 8 to 15. Men naturally tend to be larger than women and this means that their thicker fingers put the ring larger size ranges slightly than what is considered normal for women with long thin fingers. In general, rings on male hands will also have thicker bands which makes it easier to put them on or take them off when needed; plus one should buy his ring about 1/2-sized larger if he has bigger finger sizes so as not to get stuck trying hard while sliding it onto the finger.
The average ring size for women is 7, the most popular choice in women’s rings. The range between 6-8 can be expected depending on lifestyle changes like pregnancy or weight fluctuations when they gain weight. Thus, it is highly recommended to measure ring sizes with an additional quarter size in case of any possible alterations to their most consistent weight.
Here are some important points to consider.
A perfect engagement ring is one that will last forever – classic and timeless. To find this, look at your future spouse’s current jewelry and take cues from it, how you should pick out a piece for them so it suits their style preferences as well, and will make you both want to wear yours even after the wedding itself.
A diamond is a stone of beauty and rarity, but don’t let its Four Cs (carat, color, cut, clarity) fool you: certificate grading should only be one factor in your decision-making process. You may not need something flawless to create the ring of your dreams. The grade serves as an initial starting point for many people who judge their options based on this number alone–you don’t need a flawless stone with D grade quality if it gives off bad vibes. A better way would probably depend more upon “what type of feeling I get from holding/squeezing this particular rock” vs comparing grades.
Size doesn’t matter! The ring is more of an extension of your personal style, and sometimes that means intentionally opting out of ‘bling.’ It’s wonderful to see women go against traditional jewelry store molds in order to find something that speaks for themselves—whether it be big or small size preferences, color preference (or lack thereof), clarity…whatever speaks volumes about who you are as a person.
Know where the stone came from. According to Page Neal, jewelry designer and co-founder of Bario Neal, clients appreciate jewelry with backstories—especially when those stories involve ethically sourced gems. He searches high and low for mines that can prove their diamonds are 100% natural (and completely traceable) or have been handpicked by experts in different fields like metalwork & gemology. Suppliers even offer online auction listings so shoppers know exactly what they’re getting themselves into before making purchases!
When falling in love with the stone, think about what can be done to make it stand out. The centerpiece as artwork and its surroundings are like how we frame our favorite paintings or sculptures for display. Be bold but also thoughtful–your rings will reflect both your personal style as well as who is wearing them (so don’t copy other people). Get expert help by asking around, too.
Don’t get stuck on traditional engagement rings. Today, millennials are more likely than ever before to eschew diamonds in favor of something personal and different; a customized piece that matches their own vibe while still being timeless enough to match with fashion trends or society’s changing needs over time.
Consider opting for something more unique – custom-made rings. Generally, people now want the best of both worlds: quality more than size or shape. Engagement rings aren’t one-size-fits-all anymore—they’re tailored specifically to each individual couple’s needs!
You don’t have to go it alone when shopping for engagement rings. Friends and family are great sources of advice, so ask them their opinion. Nine times out of ten they’ll know what’s best in terms of aesthetics or personal preference without even having been consulted themselves previously by you- which makes getting that perfect gift easier than ever before!
Avoid getting into an agreement with the jeweler, as there may be a situation where your intended hates what you’ve come up with and can exchange it for something else that she loves. Even more so both of you will enjoy wearing these pieces together forever!
It’s not the cost! The truth is there’s no exact science when it comes to how much you should spend on an engagement ring, and some women prefer smaller cheaper diamonds (or want nothing at all). Some are going for a vintage look while others just need something basic à la Amanda Seyfried. Get your perfect match in terms of size rather than price as well!
