Average Women’s Ring Finger Size by Country

It is important to note that ring finger sizes can vary significantly among individuals, and this average serves as a general guideline.

In the United Kingdom, the average women’s ring finger size is slightly smaller than that of their American counterparts. According to a survey conducted by ABC Jewelers, the average size in the UK is X.X millimeters.

This measurement took into account data from various jewelry stores in major cities throughout the country.

Canada has its own unique average ring finger size for women. Based on data collected by XYZ Jewelers Canada, the average size in the country is X.X millimeters. This data was obtained from customers in major cities such as Toronto, Vancouver, and Montreal.

It is important to remember that these average sizes are just reference points and may not be representative of every individual. Factors such as genetics, ethnicity, and lifestyle can influence finger size.

When purchasing a ring, it is always best to consult with a professional jeweler who can accurately measure your finger and provide the best fit for you.

What Affects Ring Finger Size


The size of a woman’s ring finger can be influenced by various factors, and one of them is age. As women age, their fingers tend to become slightly larger. This is primarily due to changes in the body’s bone density and the distribution of fat.

While the increase in finger size may be minimal, it can still affect the fit of a ring.

Weight Changes

Another factor that can affect ring finger size is weight changes. When a woman gains or loses weight, it can lead to changes in the size of her fingers. Excess weight can cause fingers to become larger, while significant weight loss can result in fingers becoming smaller.

Therefore, it’s important to consider these fluctuations when choosing a ring size.


Pregnancy is a time when many women experience changes in their body, including their finger size. During pregnancy, hormonal changes can cause fluid retention, leading to swelling in various parts of the body, including the fingers. This temporary swelling can result in a larger ring finger size.

It’s advisable for pregnant women to choose a slightly larger ring size or opt for adjustable rings to accommodate these changes.

Weather and Fluid Retention

The weather can also play a role in finger size. In hot and humid climates, individuals may experience increased fluid retention, which can cause temporary swelling in the fingers. Conversely, during colder weather, blood vessels constrict, potentially resulting in slightly smaller finger size.

It’s important to consider the impact of weather conditions on ring fit, especially when purchasing rings for special occasions.

Time of Day

Believe it or not, the time of day can affect the size of a woman’s ring finger. Our fingers tend to be slightly larger in the morning compared to the evening. This is because during the day, our hands may swell slightly due to factors such as temperature, physical activity, and fluid retention.

Therefore, it’s recommended to measure ring size in the afternoon or evening for a more accurate fit.

Dominant Hand

The size of a woman’s ring finger can also differ between her dominant and non-dominant hand. The dominant hand typically has slightly larger fingers due to increased muscle development and usage. When choosing a ring, it’s essential to consider which hand it will be worn on and take measurements accordingly.

How to Measure Ring Size Accurately

Knowing your ring size is essential when shopping for a new piece of jewelry. Whether you are buying a ring for yourself or as a gift for someone else, getting the right fit is crucial. Here are several methods to help you measure your ring size accurately:

1. Trace Your Finger

One simple method is to trace the outline of your finger on a piece of paper. Then, using a ruler, measure the length of the traced area from the starting point to the tip. This measurement can be compared to a ring size chart to determine the appropriate size.

2. Use a Ring Sizer

A more precise way to measure your ring size is by using a ring sizer. These are plastic or metal devices with multiple ring size options. Simply slide the sizer onto your finger until it fits comfortably. The marked size on the sizer will indicate your ring size.

3. Consult with a Jeweler

If you want a professional opinion, visit a jeweler who can accurately measure your ring size. They have specialized tools and experience to ensure an exact fit. Plus, they can provide valuable advice on choosing the right ring design and style.

4. Order a Free Sizer

Many jewelry websites offer free ring sizers that can be sent to your home. These sizers usually come with detailed instructions on how to measure your size accurately. This method is convenient and can be done in the comfort of your own home.

5. Size Based on Existing Rings

If you already own a well-fitting ring, you can use it to determine your ring size. Place the ring on a ring size chart or measure its inner diameter with a ruler. This measurement can guide you in selecting the right size for your new ring.

Remember, accurate ring measurements are essential for a comfortable and secure fit. It is always better to have a slightly larger ring that can be resized, rather than a smaller one that may be too tight.

By using these methods, you can confidently find the perfect ring size for yourself or someone special.

Tips for Getting the Right Fit

Test Different Widths

When it comes to finding the perfect ring, one size definitely does not fit all. The width of the band can have a significant impact on how a ring fits. It’s important to try on rings of different widths to see which one feels the most comfortable and looks the best on your finger.

Some women prefer a narrower band, while others may find that a wider band suits their hand better. By trying on different widths, you can find the perfect fit for you.

Allow a Slight Gap

It’s important to leave a slight gap between the ring and your finger to ensure a comfortable fit. This gap allows for any potential swelling that may occur throughout the day. Additionally, it helps prevent the ring from becoming too tight and difficult to remove.

A general guideline is to be able to fit a small piece of paper between the ring and your finger. This ensures that the ring is not too tight, but also not too loose.

Size Up for Knuckle Rings

If you’re considering wearing a knuckle ring, it’s recommended to size up. Knuckle rings are typically worn above the knuckle, which means they need to be slightly larger than a regular ring. Sizing up ensures that the ring will fit comfortably and won’t feel too tight when worn in this unique position.

Keep in mind that you may need to try on a few different sizes to find the perfect fit for your knuckle ring.

Consider Your Lifestyle

When choosing a ring, it’s important to consider your lifestyle and daily activities. If you lead an active lifestyle or work with your hands, you may want to opt for a ring that is more durable and less likely to get damaged.

For example, a ring made of titanium or tungsten carbide is incredibly resistant to scratches and is a great choice for those with an active lifestyle. On the other hand, if you work in a professional setting and prefer a more delicate and elegant ring, a thinner band made of gold or platinum may be more suitable.

Taking your lifestyle into consideration will ensure that you choose a ring that not only fits well but also stands up to your daily activities.

Frequently Asked Questions

How often should I get my ring size rechecked?

It is recommended to get your ring size rechecked every couple of years, especially if you notice any changes in the fit of your rings. Our fingers can naturally fluctuate in size due to factors such as weight gain or loss, temperature, and even hormonal changes.

By getting your ring size rechecked regularly, you can ensure that your rings fit comfortably and securely.

Which finger do you wear a promise ring on?

Traditionally, a promise ring is worn on the ring finger of the left hand. However, there are no hard and fast rules when it comes to the finger you choose to wear your promise ring on. Some people prefer to wear it on a different finger or even on a chain around their neck.

The most important thing is that the ring holds meaning to you and symbolizes the commitment you have made.

Do fingers shrink with age?

As we age, our bodies go through various changes, and this can include changes in the size of our fingers. While it is not guaranteed that everyone’s fingers will shrink with age, it is not uncommon for some individuals to experience this.

Factors such as loss of muscle mass, changes in hormones, and the natural aging process can contribute to a decrease in finger size. If you find that your rings are becoming looser over time, it may be a good idea to have your ring size checked and consider resizing if necessary.

Can ring size change during pregnancy?

During pregnancy, it is common for women to experience swelling in various parts of their bodies, including their fingers. This swelling, known as edema, can cause the fingers to temporarily increase in size.

As a result, some women may find that their rings no longer fit comfortably during pregnancy. It is best to remove any tight-fitting rings to avoid discomfort or the risk of them getting stuck. After giving birth and the swelling subsides, your ring size should return to normal.


Finding your accurate ring finger size is an important step in getting a ring that properly fits your hand. Don’t rely on guessing – take the time to measure properly so your special ring feels comfortable and stays securely in place.

With the average women’s ring size falling between 5 and 8, you now have a starting point to begin your search. But your individual size may vary based on your location, changes to your body, and measurement method. Be sure to follow our tips to end up with the perfect fit for lifelong wear.
