You see the perfect ring online, but how do you know it will fit your finger. Unlike shoe sizes, most of us don't know our ring size. Well, good news! It is easier to measure your ring size than your shoe size.What you need to know
Your ring should fit your finger comfortably; snug enough so that it will not fall off, but loose enough to slide over your knuckle with some resistance. Easy enough, right?
Typically, women's rings in the U.S. range between sizes 3 to 9, while men's rings are usually sized between 8 and 14, and those units match up to your finger's width in millimeters. But, before you get out the tape measure, there are a few things you should keep in mind:
- Consider your knuckle. If you know your knuckle is on the larger side, you should order half a size bigger than what your finger alone indicates otherwise you won't be able slide a ring into the right place.
- Ensure accuracy with multiple tries. Measure your finger three to four different times because the size actually fluctuates depending on temperature, tending to be smaller the colder you are and more swollen if you're overheated.
Prepping for Measurement
Before you begin taking your measurements, pick the finger on which you want to wear your ring. The fingers on your dominant hand tend to be larger than those on your non-dominant hand, so keep that in mind when measuring for your ring size.
Ensure that your finger is at its normal size before taking a measurement. Cold weather can cause your fingers to shrink a bit, while heat or water retention caused by food, medications, or illness can cause finger swelling.
Three easy ways to DIY Ring size
- Using a string, floss or piece of paper
- A ring size chart
- A ring sizer
Option One: Using String, Paper or Floss to Measure Your Finger
You can measure your ring size using either string or, perhaps a more common item in your home, floss. Take one of these measurement tools and wrap it around the base of your finger, marking where the string or floss meets the start with a pen. Then, line that up with a ruler and take down its length in millimeters.
With standard ring sizes, every half a size matches up to a 0.4 millimeter increment, starting with size 3 equaling 14.1 mm, size 3.5 equal to 14.5 mm, size 4 equal to 14.9 mm, and so on. The most common ring sizes for women are 6 (16.5 mm), 6.5 (16.9 mm), and 7 (17.3 mm). For men, the most common sizes are 10 (19.8 mm), 10.5 (20.2 mm), and 11 (20.6 mm).
There is one caveat with this method: String and floss can stretch, so try not to force your measuring tool too taut because you may be forcing your ring size smaller than what it will be with a more rigid material.
Option Two: Place a Ring You Already Own on a Ring Size Chart
You can measure your ring size using a piece of jewelry that you already have and know fits you. Print out a true-to-size ring size chart—like this one attached—and place your ring on the circles until you find the one that matches up with the inside circumference of your ring.
The ring size chart also tells you how many millimeters the matching circle is as well as what ring size that measurement correlates to.
