Ring Size Guide
1. Getting Started
Online shopping offers a wide variety of choices, but when it comes to purchasing rings, it can be tricky—you can’t be certain of the fit without trying it on!
At Noirva, we completely understand your concerns, which is why we’ve created this guide to make your decision easier.
Please take the time to carefully review this guide, as all of our rings are made to order, and a 35% restocking fee applies to exchanges and refunds.
Now, let’s walk you through the measurement process!
2. Key Points to Know About Ring Sizes
1) Different Band Widths Affect the Wearing Experience
- The Band Widths We Commonly Use: We usually use a band width of 1.4 to 2 mm for our women’s rings, which can be considered narrow bands. Please check the specific band width in the product description section.
- Narrow Bands May Feel Larger: For rings with a narrower width, some customers may find that the size feels larger than expected. This is because narrow bands apply less pressure to the finger, making them feel looser when worn.
- Wider Bands and Enhancer Bands May Feel Snugger: A ring with a wide band usually feels tighter than its actual size because it covers a larger area of the finger. Therefore, if you choose a wider ring—more than 2 mm—or an enhancer band, also known as a ring guard or ring jacket, you may need to choose a quarter or half size larger to ensure a comfortable fit.
- Adjusting for a Better Fit: Please consider how the band width may affect the wearing experience before selecting your ring size.
2) Resizing Considerations
- Resizing Limitations: Not all rings can be resized easily. Rings with intricate designs and eternity bands with stones around the band may have limited resizing options. It is important to choose the correct size from the beginning if you are considering these styles.
- Potential Risks of Resizing: Resizing can sometimes weaken the structural integrity of a ring, especially when it requires a significant adjustment. For rings with side stones, resizing may also affect the settings and increase the risk of stones becoming loose.
- Alternatives to Resizing: When resizing is not suitable, alternatives may include sizing beads, ring guards, or exchanging the ring for the correct size when possible. These options can help improve the fit without compromising the ring’s original structure.
3. How to Determine Your Ring Size
1) Measure an Existing Ring
If you have a ring that fits perfectly but are unsure of its size, measure its inside diameter and band width by placing it against a millimeter ruler, as shown below.
- Please send us clear photos following the examples below, and we will assist you in choosing the correct size.
2) Use a Ring Size Gauge to Find the Perfect Size
If you do not know your ring size, a metal ring size gauge is one of the most reliable ways to take your measurements. Because it is made of metal, it closely resembles the feeling of wearing an actual ring, and you can easily identify the size by checking the labels.
For additional confirmation, you can also take the two measurement photos shown in Method 1 and send them to us.
3) Use an Adjustable Ring Sizer
Please do not fasten the ring sizer too tightly or leave it too loose. It should be able to rotate slightly around your finger without leaving a visible gap.
Sending us a clear photo of the ring sizer on your finger will help us review the measurement.
4) Get Sized at Your Local Jeweler
It’s a good idea to get sized at a nearby jeweler. However, please ask them about the band width they usually use. As mentioned above, a ring with a narrow band may feel slightly looser in the same size, while a ring with a wider band may feel more snug. The reason is simple: the more metal that covers your finger, the tighter the ring may feel.
5) Measure the Circumference of Your Finger
Unlike metal or plastic, paper strips and thread are thicker and more flexible. As a result, they can create a slight bulge or slack when wrapped around the finger, leading to a measurement slightly larger than the actual size.
Though this method is simple and convenient, it is usually used as a secondary reference because it may not provide the same accuracy as professional ring-sizing tools.
Notice: Please measure multiple times to minimize errors. Additionally, please let us know your or the wearer’s height and weight as a reference if you intend to use this method.
Use a strip of paper, a piece of string, or a measuring tape around your finger and mark the overlap. Then remove it, lay it flat, and measure from the beginning to the overlap.
Please send us a clear photo of the measuring strip or string.
In conclusion: If you are measuring at home, sending us photos of your measuring process is a very important step.

4. Sizing & Design Tips
For Ring Sizes Smaller Than US 4
Rings with smaller circumferences have a tighter curvature. This may place additional pressure on the side settings and make side stones more likely to loosen over time.
For better long-term durability and comfort, we recommend choosing designs with fewer or smaller side stones.
For Ring Sizes Larger Than US 9
Larger rings may experience greater structural stress because the metal band spans a wider circle and is exposed to more bending force during daily wear.
To maintain suitable strength and balance, we recommend choosing a ring with a band thickness of at least 1.6 mm.
If the thickness listed on the product page does not meet this recommendation, please contact Noirva to discuss customization options.
