In the Internet age, more and more rings are bought online. While all ring buyers spend lots of time looking for the best design, stones, and metal for their ring, only a few give enough attention to measuring the ring size they need. Meanwhile, the ring should not only look amazing but also fit just fine.
When you buy online, you need to know the ring size before you place an order. Similarly, if you want to buy a present for your loved one or to make that long-awaited offer, asking for the ring size in advance would spoil the surprise. The good news is that there are several simple methods that can help you find out the ring size you need without going to the jewellers.
Although these methods are quite simple and mentioned on many sites, they can produce inaccurate results if applied without caution, which will make you resize or return your ring. Here is a guide for ring sizes for the US and Canada, how to measure the ring size at home and what you need to do to make sure you have accurate measurements.
RING SIZE CHART
The ring sizes in the United States, Canada and most of Mexico are expressed in numbers from 1 to 16. While most women’s ring sizes fall between 3 and 13.5, men’s rings are usually larger, with an average size between 8 and 14.
Each ring size matches certain finger width, expressed in millimetres, with every half-size corresponding to approximately 0.4 mm width increment. The smallest ring size of 3 matches the finger that is 14.1 mm across, size 3.5 fits the finger of 14.5 mm diameter and so on. You will find the table showing the relationship between ring size, finger width and circumference below, which you will need later on when you start measuring your ring size.
|Ring size||Diameter, mm||Circumference. mm||Diameter, inches||Circumference, inches|
Most jewellers use similar charts as above, with minor differences explained by rounding decimals. Sometimes, measuring the ring size with different jewellers results in a half-size difference, so it is safer to pick a size half-size bigger when in doubt.
MEASURING THE RING SIZE WITH A STRING, FLOSS OR A STRIP OF PAPER
One of the most popular methods of measuring the ring at home without special tools is using a string, floss or strip of paper. Simply wrap a string or strip around the base of your finger and mark where they start to overlap with a marker or a pen. After that, measure the marked length with a ruler in millimetres and find your ring size from the chart above.
In doing so, you should always keep in mind that string and floss can stretch. Therefore, try to avoid overstretching the string or floss while you measure their length with a ruler; otherwise, your measurement will result in the size which would be bigger than you need.
When measuring the base of your finger, don’t forget that you will need to get the ring over your knuckle. If your knuckle is larger than the finger base, you will need to measure both places and pick the size between the two. In this situation, the ring will have the right size to slide over the knuckle relatively easily and sit comfortably on your finger, even though it can feel a little loose.
The final piece of advice with this method is to take several measurements both for the finger base and the knuckle at different times of the day to account for changes in finger size due to temperature and timing. Fingers are usually smaller in the morning and shrink in cold temperatures. You will also need 3-4 measurements to exclude occasional errors.
MEASURING THE RING YOU ALREADY HAVE
You might be spared the need to measure the width of your finger or the one of your beloved if you have another ring that fits perfectly. It can also be helpful when you want to make a gift for your special one but want to keep it a secret for a while.
In this case, you can check the size of the other ring with a ruler by measuring across the ring’s inside diameter from edge to edge. Don’t forget to take several measurements for accuracy and avoiding errors. After you find the exact diameter, you can check the ring size using the above chart.
WORD OF CAUTION FOR WHEN YOU MEASURE RING SIZE AT HOME
Some guides offer to download and print out a paper sizer or a template, which can be wrapped around your finger to measure the ring size at home. Although it sounds simple, this method comes with a caveat as most printers don’t print out in the correct size and result in shorter or longer templates. Therefore, this method is not recommended to avoid skewed measurements.
WHAT HAPPENS IF YOU ORDER THE WRONG SIZE
Sometimes, despite all caution, an error sneaks into your measurements, resulting in a larger or smaller ring than you need. You might also want your ring resized after time due to your weight fluctuations or for other reasons.
If this happens to you, don’t panic and take another set of measurements, making sure they are accurate by following the above tips: take several measurements for accuracy, measure your finger at different times of the day, and account for your knuckle size. After that, you can have your ring resized by jewellers who will either add a small amount of metal to enlarge the ring or remove metal to make it smaller. This may result in a thicker or thinner ring, but the difference would usually be unnoticeable to the naked eye.
When you choose a ring, keep in mind that not all rings can be resized due to their design without losing visual appearance. For example, this relates to the so popular eternity or infinity woman’s ring with a continuous line of stones. Similarly, rings with ornaments such as milgrain rings cannot be made smaller or larger simply by adding or removing metal. So you will need to account for your possible weight fluctuation over time and pay double attention when measuring ring size for these designs.
