The Ring Size Chart-Comprehensive Buying Guide

Introduction

Think about you’re going to order rings in bulk quantities from the factory, but the ring size does not fit your local customer. Not only will you lose many businesses, but also waste time and costs to solve this problem.

This guide will tell you the different ring size systems, the standard size for men and women, the international ring size chart comparison, and how you can be professional to tell your customers to measure their ring size by themselves.

Understanding Ring Sizes

Countries that use different ring sizing systems, with simple education, you can easily avoid mistakes.

US/Canada Sizing

The US and Canada use a numbered system that comes in sizes 3 to 13, with half sizes. Most women wear sizes 5 to 8; size 7 is the typical woman’s size. While men typically need sizes 8 through 12, size 10 is very common for men. Because of this system, it is easy to go up or down a size as each full size is about 0.8mm in diameter difference.

UK/Australia Sizing

Australia and the UK use letters instead of numbers. Sizing starts with A and continues through Z, using A½, B½, etc. for half sizes. The use of letters for ring sizes is based on the traditional English method of jewelry making. During this period, rings were stamped with letters for identification. A woman’s typical ring size in the UK is L to P.

European Sizing

European sizes represent the size of the ring based on the circumference of the ring in millimeters, which is the most accurate measurement of the size. 49 – 65 mm is the typical size range for the average person. Many jewelry manufacturer prefer this system because it provides exact measurements for working on custom work.

Ways to Measure Ring Size At Home

Method 1: Using Paper or String

This method will work if you do not have a ring you can measure already. Just find a paper, pen, and ruler at home.

1. First, cut the paper to 6-8 inches long, and make it ⅓ inch wide.
2. Then use the cut paper to wrap around the bottom of your finger that you’re going to wear the ring.
3. Make sure the strip can slide over your knuckle
4. Mark where the strip overlaps with your pen
5. Measure the distance from the mark to the start of the paper.
6. Use the above chart to convert the measured dimension to the exact ring size.

The paper should be snug but not tight. If your knuckle is larger than the bottom portion of your ring finger, measure your knuckle. This will ensure the ring comes on and off easily.

Method 2: Measure Existing Ring

This method will give you the best results at home. You will just have to find a ring that fits the target finger perfectly.

1. Check out whether you have a ring at home that fits your finger
2. Best to measure the inside of the ring by a vernier caliper; if not, use a ruler.
3. Record your measurement in mm
4. Use the conversion chart to get the closest size that corresponds to that mm measurement

Method 3: Using Printable Ring Sizer

macys.com offers a free download ring sizer; try using it, you can quickly determine your finger size.

1. Print the ring sizer to 100% scale (do not shrink or enlarge)
2. Cut the sizer out along the lines carefully
3. Wrap around your finger to see how it fits
4. Read the size where the sizer overlaps

It is helpful to double-check the sizers accuracy by measuring a distance on your paper you know first.

Tips to Make the Measurement Accurate

When to Measure

Measure in the evening when your fingers are at their widest. Your fingers swell a little during the evening, so morning measurement sometimes gives you a ring that feels tight by the end of the day.

Temperature Effects

Heat and cold can make your finger size a little different. Avoid measuring immediately after hot showers, after exercise, or after exposure to cold. The most accurate and consistent results can be achieved by measuring at room temperature.

Knuckle Considerations

In case your knuckle is much larger than your finger base, you should measure your knuckle. The ring must easily slide over the knuckle. Some will upsize to accommodate a large knuckle even if the base feels loose to the wearer.

Multiple Measurements

Always measure three times and take the average. Fingers can change slightly from day to day, so consistency is more important than just one measurement.

Ring Width Adjustments

Wide rings are tighter than thin rings. For example, if your average size is 51.5mm in European sizing and you are selecting a wide band, then you should consider going up to 52mm. Thin, smooth bands can typically be worn smaller, so you may find that 51mm is better.

What If the Ring Still Doesn’t Fit?

Rings may need occasional adjusting to fit; even with a measurement process that is as thorough as the one outlined above.

Simple rings made of gold or silver can usually be resized at home, or must receive help resizing from a jeweler, usually for free. However, rings with stones, more complex designs, or special coatings lead to potential risk for damage. If that is a concern, an exchange policy will probably give you better options.

If it must be adjusted, ring size alterations cost from $20 to $100, depending on its metal and the complexity of the design.
