How to select your ring size

An ideally sized ring will glide over your knuckle with a slight resistance, indicating a good fit, and then fit snugly around the base of your finger. It should not feel overly tight or restrict blood flow, yet it should be secure enough not to spin freely or slip off easily.

Ring size tips

When measuring for ring size, keep in mind that your dominant hand is usually slightly larger. Therefore, it’s important to measure the specific finger on the hand where you intend to wear the ring.

When selecting your ring size, it’s crucial to consider the design of the ring. Rings with wider bands, typically those wider than 4 millimeters (mm), tend to have a tighter fit. In such cases, you might need to choose a ring that is at least a half size larger than your usual size to ensure comfort. Conversely, for rings with very thin bands, those less than 1.3 mm, you may find a slightly smaller size provides a better fit.

It’s important to remember that ring sizes are usually measured in millimeters, not inches. This standard measurement ensures precision and helps in selecting the most comfortable fit for your ring, taking into account the band width and your personal comfort.

When measuring your ring size, it’s important to ensure that your body temperature is normal. This is because your fingers can shrink when they are cold and expand when they are warm. Measuring your finger when it’s at a standard temperature gives you a more accurate size, as extreme temperatures can lead to incorrect measurements and a ring that fits poorly either too tight or too loose under different conditions.

When determining your ring size, it’s important to consider that the size of your fingers can fluctuate throughout the day. Factors such as hydration and food intake can cause your fingers to swell or contract. To obtain the most accurate measurement, it is advisable to measure your ring size later in the day, preferably in the mid to late afternoon. This timing typically reflects your fingers at their most typical size, having adjusted to your daily activities and diet.

It’s advisable not to measure your ring size during pregnancy. Hormonal changes and fluctuations in body weight during pregnancy can lead to temporary changes in finger size, often causing fingers to swell. Measuring your ring size while pregnant may result in choosing a size that will not fit properly once your body returns to its pre-pregnancy state. For the most accurate and lasting fit, it’s best to measure your ring size either before pregnancy or after your body has fully adjusted post-pregnancy.

Medications can affect your ring size due to their impact on bodily fluids and tissue, potentially causing swelling or contraction in your fingers. If you are taking medication for a short period, it’s best to wait until you have completed the course before measuring your ring size to ensure you get a stable and accurate measurement. For those on long-term, chronic medication, it’s advisable to measure your ring size later in the day, after you’ve taken all your doses. This timing allows the medication’s full effects to manifest, ensuring that the ring size you choose accommodates these influences for a comfortable fit.

Avoiding Inaccuracies

Why We Discourage Using Printable Ring Size Guides

We strongly discourage the use of self-printed (PDF) ring size guides for measuring your ring size. Our experience has shown that these methods are often unreliable, and we have yet to see a successful ring sizing result from clients who use printed size charts. The primary issue with these guides lies in the variability of printer settings, which can lead to inaccuracies in scale and, subsequently, incorrect ring size measurements.

Factors such as printer resolution, paper size settings, and scaling options can all alter the actual size of the printed guide, resulting in a ring size that may be too large or too small. Because of these potential inconsistencies, we recommend using more reliable methods for determining your ring size. Ideally, you should have your ring size measured professionally in-store or request a ring sizer from us, which is designed to provide accurate measurements and avoid the pitfalls of printable guides.

Can't find a size that fits?

We suggest selecting a size that fits more snugly—the smaller option. It’s crucial to consider that your finger size can vary throughout the day. We recommend reading our Ring Size Tips to determine the optimal time to measure your finger.

Although a ring can generally be stretched to increase its size by a half or even a full size, depending on the design, reducing its size is more complex. Making a ring smaller involves cutting and resoldering, which introduces more risks compared to sizing up. Choose carefully to ensure your ring not only fits well but also maintains its integrity and design quality.

Enlarged knuckles or Finger joints

Finding the right ring size for enlarged knuckles can be challenging because there isn’t a one-size-fits-all solution. Many clients face this issue, and since each person’s situation is unique, a personalized approach is essential. Enlarged knuckles may require the ring to be loose enough to slide over the knuckle comfortably but snug enough not to move excessively on the finger.

At Ralph Jacobs, we recognize the complexity of this issue and offer several options. However, we strongly recommend booking a consultation with one of our specialists. During the consultation, we can discuss your specific needs and explore various solutions tailored to ensure your ring not only fits comfortably over your knuckle but also feels secure around your finger. This personalized approach helps us provide the best fit for your unique finger shape.

Choosing the Incorrect Ring Size

Selecting the wrong ring size not only complicates wearability but also poses risks to the ring’s structural integrity, as not all rings can be resized easily or without risk.

Too Large

A ring that is too big can easily become misshapen and lose its perfect round form. This size issue can cause the ring to shift on the finger, leading to the head or top part of the ring turning frequently. As a result, the center stone may be more exposed to surfaces, increasing the risk of scratches or other types of damage.

Too Small

Choosing a ring that is too small carries significant risks as well. A tight ring puts additional stress on the metal, which can weaken the structure over time. The continuous strain of putting on and taking off a tight ring can eventually lead to metal fatigue, causing the ring to break.

Important Safety Warning

Remove Your Ring Immediately in Case of Hand or Finger Injury

In the event of an injury to your hand or finger—particularly cuts—it is crucial to remove your rings right away. We have observed numerous instances where clients have injured their fingers, such as by broken glass while washing dishes, leading to rapid swelling and even infections.

Your fingers can swell significantly and quickly, making it difficult to remove the ring later and potentially worsening the situation. To avoid complications like severe swelling and infections, take off your rings immediately, seek medical attention, and only consider wearing your rings again once your finger has completely healed. This precautionary step is vital for your safety and well-being.
