How to Size a Ring for the Perfect Fit

So, you've found the perfect ring, and now you're wondering how to ensure that it fits comfortably and securely. Whether you're shopping online or in person, finding the right ring size can be a challenge.

While other pieces of jewelry like chains and earrings are easier to shop for visually, the fit and feel of a ring are equally as important as its aesthetics. No one wants to be caught in a cycle of buying jewelry online, trying it on at home, and returning it in hopes that one will finally click. 

If you’re looking to size up your finger for a new ring, you’ve come to the right place. Today, we’ll be going over everything you need to know about ring sizing. First, though, let’s get familiar with how ring sizes work. 

Ring Sizes Explained

Ring sizes are numbers that match the circumference of your finger. In the US, most ring sizes range from 3 to 13.5, with half sizes in between. Women's average ring size is around 6 to 6.5, while men's average ring size falls between 9 and 10.

In some other countries, rings are measured differently. Some places may use a letter-based system while others may go by a different set of numbers. If you’re shopping a U.S. store from overseas, you may want to check a conversion chart to determine the right size for your finger. 

Keep in mind, though, that ring size is not a static measurement. It can vary depending on multiple factors, such as temperature, time of day, and physical activity. 

For example, when it's hot or after you exercise, your fingers tend to swell, which can affect their circumference. Conversely, your fingers tend to shrink when it's cold, resulting in a smaller ring size. It's also worth noting that our fingers are generally larger in the evening than in the morning.

Besides external factors, your diet and health can also impact your ring size. Certain health conditions like arthritis, pregnancy, or weight fluctuations can cause changes in your fingers. 

How to Measure Your Ring Size 

You don’t have to leave your home and visit a jewelry store to learn your finger size. It can be done at home or with a sizing tool that you can order online. 

Here are some ways that you can find your ring size: 

• Printable Ring Sizer: Many jewelers offer printable ring sizers that you can download and print at home (check the GLD ring size chart here). These sizers typically include a set of circles that correspond to ring sizes. You just need to wrap the sizer around your finger and note which circle matches the circumference of your finger.

• String or Paper Method: If you don't have access to a printable sizer, you can use string or a length of paper to measure your finger. Wrap the measuring item around your finger and mark where the two ends meet. Measure the length in millimeters and compare it to your ring size chart.

• Measure a Ring You Already Own: If you currently own a ring that fits well, it can be used to determine your ring size. Measure the diameter of inside of the ring in millimeters and hold it up to your ring size chart.

Understanding Ring Size Adjustments

Depending on the ring’s material, you may be able to resize it if needed. However, not all materials can be adjusted, such as tungsten. 

The level of detail and embellishments on the ring can also affect resizing. In most cases, you may need to take it to a professional jeweler or use a repair service offered by the brand you purchased it from. 

Wherever possible, we do not recommend resizing a ring at home. This can damage the metal, void any warranty on it, and result in a broken piece that you can no longer use. This goes double for iced out pieces where there are more intricate details like intricate stone settings. 

Tips for Buying Rings Online

Shopping for rings online can be tricky, but here are some tips to help you find the perfect fit:

• Read Product Descriptions Carefully: Pay close attention to the sizing information and make sure you understand which sizing system the jeweler is using.

• Look for Size Guides and Customer Support: Check if the jeweler provides size guides or customer support to help you choose the right ring size.

• Check Reviews from Other Customers: See if other customers have commented on the ring's fit and if it runs true to size.

• Check the Return and Exchange Policy: Make sure you have enough time to try on the ring and return or exchange it if it doesn't fit.

Mistakes to Avoid When Trying Out Rings

When it comes to figuring out your ring size, there are a few common mistakes that you'll want to avoid. By keeping these in mind, you can get a more accurate measurement and a better fit for your ring.

Measuring at the Wrong Time of Day

One of the most common mistakes is measuring your finger at the wrong time of day. Our fingers tend to be at their largest in the evening, so it's best to measure at the end of your day when your fingers are their largest. When doing this, you can pick the ring size that will fit comfortably throughout the day, even if your fingers swell from physical activity or changes in temperature.

Forgetting the Size of Your Knuckle

Except for the thumb, each finger has 3 joints (knuckles): The metacarpophalangeal joint (MCP) at the base, the proximal interphalangeal joint (PIP) in the center, and the distal interphalangeal joint (DIP) closest to your fingertip. 

When measuring your finger, also note the size of its circumference around the PIP knuckle in the middle. You'll want to make sure the ring can slide over your knuckle but still fit snugly on the other side. This is particularly important if you're shopping for a wide-band or thicker ring, as these styles may require a larger size to fit as intended. 

Keep the Ring Style in Mind 

Finally, it's important to choose a style and design of the ring that you feel the most confident wearing, but also at a size that will fit you best. As we mentioned above, some ring styles or designs may fit differently than others. 

Generally, you may want to purchase a wider ring a half-size up. If you’re still unsure, read reviews from other customers to see if they had to also adjust their sizing when they made their purchase.
