How to know my ring size? Discover the guide to choose well

Rings are one of the most popular and meaningful pieces of jewellery to give as a gift (or even to buy for yourself!). However, when choosing the perfect ring for someone special or shopping online for a ring you love, you often face the same dilemma: How do I know my ring size?

Rings are a unique and personal accessory. It’s essential that they aren’t too tight, as this can be uncomfortable, nor too loose, as they could slip off and get lost. The ring should fit just right—and while it may seem like an impossible task, getting the perfect size on the first try is easier than you think. Whether you need to find out your own size, choose the right fit for a gift, or prepare for a proposal, we’re here to help you find the correct ring size.

Ring sizes and conversions

In Spain, there is a standard sizing system, with corresponding equivalents in other European and international measurements. However, some brands also have their own unique sizing systems. The most common sizes range from 8 to 30, for both men and women.

To help you find your ring size in different sizing systems, we’ve created the following chart, which includes the main measurements in European and international formats:

*Note: Measurements may vary by 0.1-0.2mm.

How to find your ring size

If you don’t know your ring size in any of the existing sizing systems, there are several ways to determine it, depending on whether you have a ring on hand or not. While not all methods are equally precise, they can give you a good estimate of your correct size.

Ring size guide

On the JOSE LUIS Joyerías website, you can find a ring size guide to help you determine the right ring size. You can access it here. You will need to print the guide and have a well-fitting ring (one that slides on and off easily) to use as a reference.

The process is simple: match the inside of your ring to one of the printed circles, and the one that aligns perfectly is your size. Be careful! The printed circle’s line should not be fully hidden inside the ring nor too far apart from it—the correct size is the one where the line just touches the inner edge of the ring.

Measuring the diameter of a ring

If you don’t have access to a printer, an alternative (though less reliable) method is to use a rigid ruler to measure the diameter of your ring. You can do this by placing the ruler directly across the ring or by tracing its outline on a piece of paper and measuring the diameter from there. Afterwards, refer to the size chart from the previous section to find your ring size.

This method is not as precise because measuring the internal diameter of a ring with a ruler can be tricky, but it will give you a rough estimate.

Measuring your finger

Another way to determine your ring size is by measuring the circumference of your finger. There are professional ring sizers that fit around your finger and provide an accurate size, but if you don’t have one, there are other methods you can try:

• If you have a sewing tape measure: Wrap the tape around your finger and note the measurement in centimetres. Then, refer to the size guide for the correct ring size.
• If you don’t have a tape measure: Cut a thin strip of paper and wrap it around your finger. Mark where the ends meet, making sure not to pull too tightly, then measure it with a regular ruler or match it against a printed ring size chart. You could also use a thin piece of string or thread in the same way.

Professional ring sizers

One of the most accurate ways to find your ring size is by visiting a jeweller, where they will have professional tools to measure your size precisely. Some of the most commonly used tools include ring mandrels (tatum stick), ring sizers, and callipers.

Tips for finding your ring size

Before measuring your ring size, consider the following factors, as they can significantly affect the result:

• Temperature and humidity affect your hands. Your fingers tend to swell in warm weather and contract in cold temperatures, which can cause variations in ring size.
• Measure the exact finger on which you’ll wear the ring. Each finger has a different size, and the same finger on your dominant hand may be slightly larger than on your non-dominant hand.
• Wider rings fit more snugly. If you are measuring using a reference ring, try to use one with a similar width to the ring you plan to purchase.
• A well-fitting ring should not be too loose or too tight. It should slide over the knuckle with some resistance but not feel uncomfortably tight once on.
• If you are between two sizes, choose the larger one. It is easier to adjust a ring that is slightly too big than one that is too small.

With all these methods gathered in this guide, finding your ring size is easy. Don't forget to browse our available rings, and if you have any questions, feel free to contact us—we’d be happy to help!
