DIY Measure Your Ring Size

The best way to figure out your ring size is to get measured at a local jeweler, but that’s not always an option. If you’re in need of a DIY ring sizing method, try one of these three easy ways to measure your ring size at home. If you want your DIY sizing to be as accurate as possible, be sure to read our ring sizing tips before you start measuring your fingers. 

Ring Sizing Tips

• Understand how a ring should fit. Your ring should fit snugly yet comfortably at the base of your finger. You want your ring to be loose enough to take on and off easily, but tight enough for there to be some resistance as you pull it over your knuckle. 
• Measure the exact finger(s) you want to wear your ring on. Your ring size can vary not only between fingers but also between your hands. For example, your left-hand ring finger may be a slightly different size from your right-hand ring finger. 
• Measure your ring size a few times throughout the day. Your fingers change slightly in size depending on your body temperature. Your fingers will be slightly smaller when you’re cold and slightly larger when you’re hot. To make sure your ring will fit regardless of your body temperature, take 3 or 4 measurements throughout the day. 
• Think about your knuckles when measuring your ring finger size. Remember that your ring will need to get over your knuckles when you’re putting it on, so be sure to think about both the size of your finger and the size of your knuckles. 
• Compare your results to standard ring sizes. Most women wear rings between size 3 and size 9, and the average women’s ring size is size 6. Most men wear rings between size 8 and size 14, and the average men’s ring size is size 8.5. Consider how your ring size measurement compares to these typical sizes. If you’re outside these ranges and you don’t have a particularly large or small hand, there may be something wrong with your measuring strategy.
• When in doubt, go with the larger size. If you find that you’re in-between ring sizes, it’s usually best to go with the larger size. This is especially true if you have larger knuckles. 
• Don’t measure your fingers with anything that stretches. Some people suggest using floss or a piece of string to measure your ring size, but there are better DIY sizing methods. Why? Floss and string are both stretchable, making them less than ideal for accurate measuring. The difference between half sizes is only 0.4 millimeters, so using something that’s even slightly stretchy to measure your ring size is not the best idea. 
• Understand whether or not resizing is an option Some rings, like plain yellow gold wedding bands, are very easy to resize. But other rings, like diamond eternity bands and tension set diamond engagement rings, can be challenging or impossible to resize. If you’re buying a ring style that’s hard to resize, be extra careful when measuring your ring size. 

DIY Ring Sizing Method #1: Use a Paper Ring Sizer

To use this method, you need a printer, scissors, and a printable ring sizer, like the one available here in our free Ring Size Guide. 

1. Print out the paper ring sizer in our Ring Size Guide. Make sure you print with your printer’s Page Scaling set to “None.” You can double-check that your page is printed correctly by measuring the two-inch and twenty-millimeter marks on the chart with a ruler. 
2. Cut out your paper ring sizer and cut a slit in the perforated area along the strip of paper. 
3. Wrap your paper sizer around the widest part of your finger, keeping the numbers on the outside. 
4. Slip the pointed end of your sizer through the open slit on the other end and note the number it lines up with. 

DIY Ring Sizing Method #2: Compare Your Own Ring to a Ring Size Chart 

It’s easy to figure out your correct ring size using this method, but you need to have an existing ring with a perfect fit. You also need a printable ring diameter comparison chart, like the one in our Ring Size Guide. 

1. Grab the ring that has the fit you want for your new ring.
2. Print our ring size chart, making sure you print with your printer’s Page Scaling set to “None.” You can double-check that your page is printed correctly by measuring the two-inch and twenty-millimeter marks on the chart with a ruler. 
3. Place your ring on the sizing circles until you find one that lines up with the inside diameter of your ring.

DIY Ring Sizing Method #3: Order a Ring Sizer 

The most accurate way to figure out your perfect ring size at home is to order a ring sizer online, then use it once it arrives. This is an easy and inexpensive option, but it does involve a bit of waiting since you’ll have to wait for your sizer to come in the mail. 

There are two common types of at-home ring sizing tools: keyring sizers and plastic measuring tape sizers. Both of these tend to be more accurate than using a printable sizer since they allow you to simulate slipping each ring size on and off.
