What Is the Average Ring Size for Men?

Shopping for wedding rings can be a journey. Whether you’re a stylish man or a casual guy, chances are that the scales of the jewelry world remain an unexplored territory. Well, you’re in luck! We’ve created a no-nonsense ring size guide so you can find the perfect fit. But before diving into the nitty gritty, it makes sense to get a baseline for ring size itself.

So, what is the typical men’s ring size?

The average male ring size in the U.S. is a 10. However, if you happen to be shopping in the United Kingdom, you will want to look for “T ½.” Japan and Switzerland both come in at 20, even though they have different conversion scales. For Japan, simply double the U.S. measurement. For Europe, you can add 10.

What are the exact measurements?

Need to know the specific measurements of a ring? Across the board, the standard “stock” size (aka, a ring size around 10) possesses an inside circumference of about 2.44 inches or 62.1 mm. And the inside diameter is .78 inches or 19.8 mm. Keep in mind that a wider band will slightly alter these measurements.

Men’s ring size conversion table (U.S., U.K., EU, Japan)

Use this men’s ring size chart to convert ring sizes between the most common systems. Measurements are approximate and shown in both diameter (mm) and circumference (mm).

Wide band sizing adjustments

If you’re choosing a ring with a wide band (8mm or more), you may need to go up slightly for comfort. That’s because wider rings cover more surface area on your finger, which increases friction and resistance when sliding over the knuckle.

Take a look at the chart below to get an idea of your adjustment:

Finding your ring size doesn’t have to be a mystery. Here are a few easy, tried-and-true ways to figure it out.

1. Use a printable ring sizer

Download and print our Ring Size Chart (make sure printing is at 100% scale).

Cut along the guide, wrap the strip around the base of your finger and match the measurement to the nearest size on our chart. And there you have it!

2. Measure an existing ring

If you already have a ring that fits perfectly, you’re halfway there.

• Lay it flat and measure the inside diameter in millimeters.

• Match that number to the chart above for your U.S. size.

3. Use a string or paper strip

No ring? No problem.

Wrap a thin piece of string or paper around the base of your finger. You want it just tight enough to stay put, but not so tight it squeezes.

Mark where it overlaps, measure that length in millimeters and compare it to the conversion table. That’s your finger’s circumference (and your ring size!).

4. Get professional-sized

Most jewelers can measure your finger using a ring mandrel or metal sizer. This is the best ring size method for accuracy, especially if you’re buying a high-value ring or have thick knuckles.

What are some other factors to keep in mind when measuring ring size?

Depending on the time of day, the internal diameter of your ring finger’s size will fluctuate by about 0.7 mm, and the fingers on your dominant hand will likely be bigger than those on the mitt opposite. For the most accurate ring size, we recommend measuring your finger size at the end of the day. 

If you go to a jeweler in person, they should be able to provide you with a ring sizer tool to help measure your finger. Don’t have time to visit the jewelry store? No worries! We have a handy online ring size chart you can reference from the comfort of your own home.

Ring Sizing Tips to Consider

Ah, the old shoe trick. We’ve all heard it, so it has to be true, right? Right? We hate to break it to you, but that just isn’t a real thing. While your ring size can correspond perfectly (or at least within a half size) to your shoe size, that’s just a coincidence.

So, what can you do to find the perfect size? Before wrapping a measuring tape around the base of the finger, you’ve got a couple of options.

Option 1: Work From Average

There’s a decent chance you probably wear a size 10 ring. It is, as we know, the most common ring size for men. Does that mean you’re guaranteed to wear a 10? Well, no. You might have slender fingers that require a smaller size or big fingers that would do better with a larger size. Definitely tough to guess the correct ring size there. Take your left hand and then utilize some tools you can find around the house, like a piece of string to wrap around your finger. Once you get the circumference of your finger with the string, lay it next to a tape measure to determine the measurements. Then, consult our ring chart, starting with the average size, and go from there.

Option 2: Just Get Close

Hand grenades, horseshoes and certain types of rings, as the saying goes. While you can’t resize all rings, there are plenty of materials that can be resized. You can go up to about one ring size up or down without much trouble. As long as you’re in the ballpark, you should be able to ensure a comfortable fit after resizing. Do note that not all ring materials can be resized, so make sure you’re getting the size exactly right if you’re getting one of those. At Modern Gents, we offer affordable rings with hassle-free returns and exchanges, so if you don’t feel confident about how your ring fits, we’ll make sure to get you a ring you feel comfortable in!
