There are three common ways you can measure your ring size right at home so you can finally get your ring measurement right, for good.
Don’t guess it, measure it for the right fit.
Ring Size Guide
- Step 1 – Get a non-stretchy string or paper about 6″(152MM) long and 1/4″(6.5MM) wide.
- Step 2 – Wrap the piece of string or paper strip around the base of your finger. It has to fit snug, but not too tight.
- Step 3 – Mark the point on the string/paper where it overlaps forming a circle.
- Step 4 – Measure the length of the string/paper from the starting point to the mark.
- Step 5 – Compare your measurement with this chart to determine your ring size.
Tips & Tricks
If you are between sizes, order a larger size. Make sure your finger is at a normal body temperature — fingers can shrink or expand when cold or hot. If your knuckle is much larger than your finger’s base, take two separate measurements, and choose a size in between. You want a ring to fit over your knuckle, but not be too loose or it will shift around.
- Measure your fingers at the end of the day when they’re at their largest.
- Cold weather can shrink your fingers up to half a size, so make sure they’re warm.
- Lastly, alcohol and salt can make your fingers swell, so refrain from measuring them after cocktails and appetizers.
When measuring your finger, your measurements need to be a 100% accurate as even a fraction of a millimeter can make a difference
Global Ring Sizing Systems
There are several systems for indicating the size of a ring used around the world:
- In the United States, Canada, and Mexico, for indicating a ring size uses a numerical measure, for whole and half ring sizes. An increase of a full ring size is an increase of 0.032 inches (0.8128 mm) in diameter or roughly 1/10 inch in inside circumference.
- In the United Kingdom, Australia, New Zealand, South Africa, and Ireland, the ring sizes are specified using an alphabetical letter, for full and half ring sizes
- In Japan, India, South America, and China, ring sizes are specified using a numerical measure, that only has whole size rings, and does not have a direct correlation with diameter or circumference.
- In Italy, Spain, Netherlands, and Switzerland, ring sizes are specified as the circumference minus 40mm. A 50 ISO was a 10 in Switzerland.
- In France and Germany, the numbers of each size simply translate to the circumference of the inside of the ring in millimeters. So a size 40 would mean the inside circumference of a ring is also 40 mm.
This is a chart that will be extremely helpful for you to determine the ring size that you need. You can either make use of a tape or a small piece of string to measure the area that will be occupied by the ring. When it becomes a complete circle, make a mark on such string. This will be helpful for you to compare with the chart that is mentioned below. For extra width, you can add another size to accommodate.
