Written by Rachel


You’re about to get hitched, and naturally, you’d want every aspect of your wedding to go as smoothly as possible. And that includes that moment when you exchange your vows and put your wedding rings on each other’s fingers. This is when getting the proper ring size matters. Fortunately, you can count on a mens wedding ring sizes chart to know the groom’s size.

Printable Men’s Wedding Ring Sizes Charts And Sizing Tools

Looking for a printable men’s ring sizes chart? Check these out.

This has a ruler at the top and circles corresponding to the ring sizes. You can use the ruler to measure the cut string, dental floss, or paper strip and get the length. Meanwhile, you get an existing ring and simply place it above the circles until you find the one that matches its size.

You can also use this as a reference for the string and existing ring method. Straighten the string (floss or paper strip) and find the horizontal line that matches its length. Note that the millimeter here corresponds to the diameter of the circle.

This printable strip has a ring measurement ranging from size 0 to 16. Before wrapping it around the ring finger, make sure to slice the indicated slot.

6 Methods To Measure Men’s Wedding Rings

Mens wedding ring sizes chart usually shows a range from 3 to 15, and each number corresponds to a ring’s inner circumference measurement. For example, ring size 3 means that the inner circumference measures 44.2 millimeters. Meanwhile, ring size 15 is equal to about 74.8 mm.

When using different techniques to measure a man’s wedding ring size, take note of the circumference of the base of the ring finger and choose a ring size that gives a wiggle room of .25 or .50 mm. Also, consider the size of the knuckle. If it’s bigger than the base, settle with a size that falls between the two. 

Using a tape measure

If you have this flexible measuring tool at home, wrap it around the base of your finger and note down the length (be careful not to wrap it tightly). 

Before you take the measurement, make sure that you’re thoroughly prepared. Measure at room temperature at the middle or end of the day. Don’t measure when you’ve just eaten, had a significant fluid intake, or performed high-impact activities — all these can make your hand swell.

When you use this method (or any other method), measure three to four times to help guarantee accuracy.

Using a string, dental floss, or paper strip

Get a string, floss, or a thin paper strip, then wrap it around the finger. Note where the ends overlap and cut it from there. Use a ruler to determine the length of the cut string, floss, or paper strip. 

If you don’t have a ruler, print a ring size chart. One version has a ruler element complete with markers in inches, centimeters, millimeters, or ring size equivalent. Another version has pairs of circles and horizontal lines. Each pair corresponds to a certain ring size; in some charts, the horizontal line has a millimeter measurement that refers to the circle’s diameter above it.

Straighten your string, floss, or paper strip and identify the line that has the same length as it. 

Using a ruler

Though a ruler isn’t as flexible as the tools mentioned above, you can still use it if that’s the only measuring tool available at home. 

Choose the finger where the ring will be worn and pick a starting point. From the starting point, pivot your ruler carefully (remember that the ruler must not move away from your skin). Once you’ve completed the spin and reached the starting point, note the measurement in millimeters. 

Using a printable ring sizing tool

Many ring sizers are available online that you can print at home (You can also order a keyring online). They look like a combination of a tape measure and a paper strip. However, instead of a millimeter measurement, the units are already the ring sizes. 

On one end of the tool, you have a wider portion where you have to slice a slot. That slot is where you’ll insert the thinner part (where you can find the ring sizes). To use it, simply wrap the sizer around the finger. Put the other end through the slot and see which ring size fits the finger.

Using another ring as a reference

If the groom has another ring that fits his ring finger, uses that as a reference when shopping for a wedding ring

You can take that to a jewelry shop. Or, if you’re ordering the ring online, use a tape measure, a string, a paper strip, or a ring sizer printable (the one with circles) to know the size of the existing ring. Even if you fail to order the perfect size, leading shops like James Allen, Clean Origin, and Blue Nile offer complimentary resizing for the rings you’ve bought from them.

Going to a professional jeweler

If you want to take away the burden of measuring the ring size yourself, you can also visit a jeweler. Professionals use a special device to take a more accurate measurement of the finger. Jewelers such as James Allen have a virtual ring sizer to help their customers.

What’s The Average Men’s Wedding Ring Size?

Generally, men’s fingers are larger and wider than women’s. Therefore, their average ring size is about 8 to 14. That is equivalent to around 69 to 72 mm. Men also tend to choose a wider band (8 mm to 10 mm on average). This is to make the ring proportional to their fingers.

What To Do If Your Size Falls Between Two Ring Sizes?

The question of how to measure ring size doesn’t end with just taking the circumference of the base of the ring finger. In many instances, the measurement taken will fall between two ring sizes. In this case, you have to choose the larger size. Remember that it’s always easier to resize a ring to make it smaller. 


With the help of a mens wedding ring sizes chart, you can get a ring that properly fits the groom’s ring finger. However, getting the right size is just one part of the equation. Explore our website for more wedding ring-buying guides.
