Ring Sizing

There are two types of sizing systems in North America; Standard Fit and Comfort Fit. Standard fit rings and wedding bands are the most common types. Comfort Fit is newer and not as well known as Standard Fit. Both types of fit are explained below.

Comfort Fit:

This type of fitting is defined as a ring that is domed in the interior (where the ring touches the finger), instead of flat, like Standard Fit. The diameter at the exact middle of the ring (between the two edges) is smaller than the diameter at the edges of the ring. This type of fit is most commonly used in rings that are difficult to resize, such as tungsten, ceramic, cobalt chrome and titanium. The advantages of Comfort Fit are the ring slides over the knuckle easier and the ring creates less friction because it covers less skin surface area.

Determining Comfort Fit Size:

A good method of determining your Comfort Fit size is to first determine your Standard Fit size at a local jeweler (explained below), and then order a half size smaller. For example, if you are measured for a Standard Fit size 9.0 by your local jeweler, you should order a Comfort Fit size 8.5. This is simply a general recommendation, not a hard rule. For rings that are wider than 8 mm, it is not recommended to go down half a size because rings wider than 8 mm fit tighter. Ring sizes are a bit like shoe sizes and differ slightly from manufacturer to manufacturer. This is why different jewelers may measure your finger at slightly different sizes. The most accurate way to determine your Comfort Fit size is to get our adjustable ring sizer and have it delivered right to your doorstep.. Our ring sizer is very accurate so, you do not need to order a half size smaller. Just order the exact size you were measured at by our ring sizer. It costs only $4.99 and you can get it here

Standard Fit:

This type of fitting is defined as a ring that is flat along the interior of the ring (where the ring touches the ring finger). This is easiest to illustrate by comparing the interior of the ring to the interior of a pipe, it is the same diameter from one edge to the other. This type of fit is most commonly used in precious metal rings such as platinum, palladium, and white gold. Although it is slightly less comfortable to wear when compared to Comfort Fit, Standard Fit is definitely not “uncomfortable”. Standard Fit has been used in the jewelry industry for centuries.

Determining Standard Fit Size:

The most accurate method of determining your Standard Fit size is to visit a local jeweler. They will most likely have a tool that looks like a bunch of rings on a keychain. This will provide an accurate measurement for any of our Standard Fit rings. You may also request our ring sizer, which is very accurate. 

International Sizing:

If you live outside of North America, you can go to a jeweler near you to get your finger measured. Then, go to our international ring size conversion page to find the correct US ring size to order. Or, if you can find out the diameter or circumference of your ring size in millimeters, we will be able to convert it to the proper US size as well. If you can wait about 1 - 2 weeks, you may request a our ring sizer and we can send it to any country in the world, just pay shipping. Just fill out the form to the right. If you do not see your country, e-mail us so we can add it for you.

Ring Sizing FAQ's

- Why do fingers swell when sleeping?

Fingers can swell up during the night for many reasons. One of the more common causes is having a diet high in sodium (salt), which makes water accumulate in the tissue and cause swelling. Lying still for prolonged periods of time may also lead to swollen fingers. Other benign causes are poor sleeping positions that may put pressure on the hands, warmer temperatures, taking certain medications, and pregnancy. However, there are also some more serious finger swelling causes which may require a visit to the doctor. Waking up with swollen fingers frequently may indicate arthritis, carpal tunnel syndrome, or kidney issues.

Can you tell ring size by height and weight?

No, you can not tell a ring size by a person’s height and weight. While taller people often have larger hands, this is not always the case. Shorter people may also have larger hands or wider knuckles. Weight does have a bigger impact on ring size, which means that a person’s ring size will fluctuate with weight gain or weight loss.

Is a 2mm wedding band too thin?

Generally, a wedding band should be at least 2mm to ensure its durability and integrity over time. Ultra-thin rings of 1mm and 1.5mm may crack or bend more easily. Many women prefer to wear their engagement ring alongside their wedding ring, which makes 2mm-wide rings a popular choice.

What is the average wedding band width?

The average wedding band width for men is 8mm while for women it’s 4mm.

 Does resizing a ring damage it?

Several factors can determine if resizing a ring will damage it. For example, adjusting a ring too many sizes up or down can damage the ring or the design. Inlays, prong settings, and delicate patterns may restrict how much a ring can be resized or even if it can be adjusted at all. The type of metal also plays an important part. Gold, silver, and platinum are easy to resize. Titanium rings are difficult to adjust in size and they can not be adjusted to a smaller size. Tungsten carbide and ceramic rings can not be resized without completely breaking the ring.

Is it better to size up or size down a ring?

It is always better to go up a size. Not only because it is safer to wear a larger ring, as a tighter one may cause swelling, but also because it is easier to size down a ring than to enlarge it. Of course, some rings can not be resized at all, like tungsten carbide or ceramic rings. During summer, fingers can also swell and make a ring fit tighter.

 Does ring size change with age?

Yes, ring size may change with age due to a range of factors. Weight gain or weight loss, muscle gain or muscle loss, arthritis, and other illnesses can have a direct impact on ring size.

 Is it true your ring size is the same as your shoe size?

No, your ring size is not the same as your shoe size. If yours match, it’s not something common.

Do wider rings fit tighter?

Yes, wider rings fit tighter on the finger and thus affect ring size. In general, for standard sizes and rings of 5mm and 6mm, you should order a ¼ size larger, while for 6mm and 8mm you should buy a wedding band ½ size larger. For comfort size rings that measure under 8mm in width, you should order ½ size smaller than standard size as these rings have a rounded interior and fit more loosely. So if you have a standard size of 8mm, order a 7.5mm comfort fit ring. Comfort rings wider than 8mm fit like a standard size, as they fit more tightly. Visiting a local jewelry store is the safest way to find exactly what width and ring size fit you perfectly.

 How many mm should a man wedding band be?

Choosing a wedding band width should always be a matter of personal preference. The average men’s wedding band width is 8mm. Generally, men with larger hands and fingers prefer a wider wedding band of 8mm-12mm, but many men choose a 6mm wedding ring. The width also depends on the ring’s style, for example if it’s a domed ring or a design with an inlay that may make the ring seem narrower.

 Can you tell a woman ring size by her shoe size?

No, you can not tell a woman’s ring size by her shoe size, as these measurements are not correlated or the same.

Will my fingers get skinny if I lose weight?

Yes, if you lose weight your fingers will also become thinner. The change will vary depending on the amount of weight loss and the person’s hand size and finger shape.

How do you size a comfort fit ring?

The best way to make sure you get the perfect comfort fit size for your wedding band is to visit a jewelry store. However, if this is not possible, ordering a comfort ring size in a half a size smaller than a standard ring size is generally the best option and applies to most rings. For wider wedding bands of 8mm and over, you should order a standard size, as wide rings usually fit a bit tighter on the finger.

How thick should a wedding band be?

The average wedding band width for men is 8mm. Many men prefer a thinner wedding band of 6mm, but others like extra-wide designs of 10mm and 12mm rings. For women, the average wedding ring width is 4mm, but a 2mm thin wedding band is a great choice if they want a more delicate ring or prefer to wear both the wedding band and the engagement ring on the same finger. Couples who want to wear matching wedding bands usually choose sets in 6mm and 8mm sizes, as these are more common. Hand size, finger size, available styles, and personal preference all contribute to the choice of wedding band width. Even someone’s job may affect the chosen wedding band size, as people who use their hands a lot as they work may prefer a slightly wider ring.
