Different Ring Size Conversions

While you may wear one size in the U.K., your sizing in the states may be completely different. Thankfully, though, conversion charts are available to ensure you order the right size regardless of which country the ring was sized in, which ensures complete accuracy.

Ring sizes in the United States and Canada range from 3 to 13, which includes half and quarter sizes. A ring’s size is determined by its diameter or circumference and is measured in inches or millimeters. The diameter measures the inside length of the ring, whereas the circumference measures the length of the entire band. 

International ring sizing involves the same measurement process, but the numbered sizes run on different scales, which vary by country. Australia and the United Kingdom actually use an alphabetical letter sizing system.

How To Measure Ring Size With A Tape Measure

Using a measuring tape is considered to be the best and most accurate method to determine your ring size. Give yourself enough space to accommodate your knuckles for the best results. Also, you should measure the finger where you plan to wear the ring, since the finger size on your left and right hands may differ.

STEP 1: 

Place the measuring tape over your finger and pull it around into a circle. 

STEP 2: 

You should adjust the size of the circle, move it over your knuckles, and make sure it fits comfortably.

STEP 3: 

Take note of the measurements in millimeters and use the comparison chart if needed. 

How To Measure Ring Size With A String

This next method is simple and works well for those who don’t have a ring nearby. All you need to do is take some string or ribbon and wrap it comfortably around your ring finger.

Once the piece of string is around your finger, carefully mark the spot where the string overlaps. For an accurate result, try to make the smallest mark possible. Then, take the string and measure it against a ruler or measuring tape. Enter your measurements here in either millimeters or inches. We’ll do the calculations for you and, voila, you now have your ring size.

3. Use non-stretchable material – If you’re measuring your finger on your own, you want an accurate measurement! Good materials: ribbon, twine, even paper.
4. Measure your finger close to your knuckle – This is where the ring will usually sit, so you want it to be comfortable.
5. Measure your finger in the middle of the day – Our fingers tend to swell overnight, so it is recommended not to take your measurement in the morning as you wake up. 
6. It’s also recommended to not measure your finger, When the weather is either too hot or cold, after an intense workout or if you are sick.

These include:

• Eternity rings 
• Ceramic rings 
• Rings made from wood 
• Tungsten

FAQs

How will I know if I have the right size?

A good ring size should fit snug around the base of your finger without bulging or leaving any indentations. However, the ring should also be loose enough to slide over your knuckle. Check if your ring fits right by pushing it up from underneath and making sure there is a small space between it and your finger. This means there is enough room.

Does band thickness affect size?

Yes, band thickness can affect your ring size. The more a ring covers your finger, the tighter it will fit. In addition, stacking many types of bands, such as a wedding ring set, will increase your ring size. We recommend measuring your ring size with a sizer that’s close to the thickness of the ring that you’ll be wearing.

How to secretly find someone’s ring size?

Planning a surprise romantic and creative proposal? You can easily find out your partner’s ring size without them knowing. One of the easiest options is to simply ask their family or friends. Another way to measure your partner’s ring size secretly is by measuring a ring they already wear.

Are men’s and women’s rings measured using the same scale?

Yes, women’s and men’s ring sizes are measured on the same scale. The average size of men’s hands tends to be larger than that of women’s, so they will fall into the larger category.
