How to Choose Your Ring Size: Practical Methods

Whether it’s for you or for your loved one, choosing a ring is always tough. Not only its appearance but also the right ring size, and avoiding the mistake of getting one that’s too small or too large. Our practical tip of the day.

Here are a few tips to correctly choose your ring size, with practical illustrations.

Methods for choosing the right ring size

To determine your ring size, consoGlobe.com offers 4 methods:

1. Measure manually the circumference of the finger that will wear the ring
2. Measure the size of your ring with a ruler
3. Use our virtual ring sizer
4. Have your finger measured by a professional jeweler

1. Measure the circumference of your finger manually

• Grab a tailor’s measuring tape or cut a strip of paper or a piece of string several centimeters long.

• With this strip or the measuring tape, wrap it around the finger that will wear the ring at the most prominent knuckle: it’s often recommended to measure at the level of the second phalanx, in the middle of the finger.

• Make a mark where the strip meets.

• Unwind your strip and measure with a millimeter ruler the length needed to go around your finger. If the mark falls between graduations, record the higher graduation.

• To know your ring size, refer to our conversion table above. Example: if the measured length is 5.4 cm, the size to order is 54.

Be mindful of heat and swelling

•  Measure your finger’s circumference at the end of the day, when the temperature is higher. It’s when your fingers are most swollen. This will help you avoid choosing a ring that fits too tightly.
• If you’re between two sizes, choose the larger one

document.getElementById(‘diameter-input’).addEventListener(‘input’, function(e) {
const diameter = parseFloat(e.target.value) ;
const container = document.getElementById(‘result-container’) ;
const display = document.getElementById(‘ring-size’) ;
const advise = document.getElementById(‘advise-text’) ;

if (diameter > 10 && diameter < 30) {
// Standard formula : Diameter * PI = Circumference (FR sizing)
// We round to the nearest whole number since sizes are often integers
let size = Math.round(diameter * Math.PI) ;

container.style.display = ‘block’ ;
display.innerText = size ;

if (size % 1 !== 0) {
advise.innerText = “If you’re between two sizes, we recommend going with the larger one.” ;
} else {
advise.innerText = “Precise measurement based on the diameter entered.” ;
}
} else {
container.style.display = ‘none’ ;
}
}) ;

2. Measure the inner diameter of your ring with a ruler

Measure the inner diameter of one of your rings with a ruler or caliper and note the corresponding size from the conversion table below.

3. Use a virtual ring sizer:

For women, the average finger circumference is between 52 and 54, sizes suggested by consoGlobe. To determine your ring size, use the virtual sizer below, making sure that the 10 cm marker on your screen reads exactly 10 cm.

• Place one of your rings (the one that fits your finger best) on the different circles of the sizer that determine your finger girth.

• Move your ring across the screen until you find the inner diameter that corresponds. When the inner diameter of your ring exactly matches the inner diameter of a circle, you have found the finger size that suits you.

Note: The outer edge of the sizer’s line must still be visible. If there’s any doubt, choose a size up, because fingers tend to swell slightly in the summer.

4. Have your finger measured by a professional jeweler

They will use a ring sizer (a set of rings of different sizes that they try on your finger until they find the one that fits) or a triboulet, a cone-shaped sleeve into which a ring is slid to measure its inner circumference.
