A Man's Guide to Getting the Right Wedding Band Size

Key Takeaways

Here's a fast rundown to ensure the perfect men's wedding band fit:

• Go Pro: A jeweler's measurement is always best for precision.
• Pay Attention to the Width & Fit: Size up a half-size for wide bands and be aware if you're ordering a comfort or standard fit.
• Time it Right: Take the measurement in the afternoon when results are most accurate.
• Know Your Metal: Ensure your selected metal can be resized if required.

Sizing correctly from the beginning is the most critical aspect of purchasing your ring. Your ideal wedding band should be such a part of you that you hardly notice it. Yet, an improper fit can make that symbol a daily annoyance. Here, you'll learn simple steps to size your finger and discover how details like ring width and even the time of day can impact your ultimate size. Let's get it right the first time!

Men's Ring Size Basics and Sizing Systems

The US uses a simple number system for men's ring sizes that usually goes from size 8 to 14. Each full size up is an increase of approximately 0.8mm in diameter. For an even more precise fit, half- and even quarter-sizes are also available. The most reliable way to find your size accurately and without guesswork is to use a professional ring sizer.

The Men's Ring Size Chart

A men's ring size chart is an easy way of converting finger measurements to the US ring size number. You'll see two general measurements: circumference (the measurement around the inside of the ring) and diameter (the measurement across the inside of the ring). Both are usually in millimeters.

• Diameter: The straight-line distance through the middle of the ring.
• Circumference: The complete distance around the inner edge of the ring.

US Ring Size	Diameter (mm)	Circumference (mm)
8	18.2	57.2
9	18.9	59.5
10	19.8	62.2
11	20.6	64.8
12	21.4	67.5
13	22.2	69.7
14	23.0	72.3

You can use this ring size chart to match your measurement to the correct ring size.

A Note on International Ring Sizing

Ring sizes differ throughout the world. The UK and Australia work in letters, and Europe uses a different set of numbers. Be certain to find out which method they are using if you are going to be shopping online or from an international jeweler. Double-check your men's ring size chart and ask the retailer for help if you are unsure.

The Best Ways to Measure Your Ring Size

Now that you know the basics, it's time to find your correct ring size. There are several reliable ways to measure, each with its pros and cons.

Method 1: The Gold Standard – Go to a Professional Jeweler

For the most accurate men's wedding band fit, go to a professional jeweler. Jewelers have calibrated ring sizers for men—metal or plastic rings in each size—so you receive an exact measurement. This is particularly crucial if you desire a flawless men's wedding ring fit.

• Expect the jeweler to try several sizers to find the best fit.
• Request to be sized more than once, preferably by two different jewelers, to ensure your size.
• Professional sizing is easy, quick, and typically free.

Method 2: The Reliable At-Home Option – Use a Physical Ring Sizer

If you wish to take your measurement at home, purchase a ring sizer for men online. These are inexpensive and simple to use.

How to take the ring size at home using a ring sizer:

• Slide the sizer onto your finger.
• Adjust to fit comfortably but not tightly.
• Ensure that it slides over your knuckle with a bit of resistance.
• Draw a line where the paper sides meet.
• Measure the distance between the lines. That's your circumference.

Repeat a few times for precision, and measure both hands if you're not sure which finger the ring will go on. Or, for a hassle-free alternative, Saga Bands provides a free Ring Sizer service—order one online and accurately measure your men's wedding band size at home.

Method 3: The DIY Method (Use with Caution) – The String or Paper Test

This is the most popular home method, but also the least precise. Only use it if you cannot obtain a ring sizer for men. Steps:

• Cut a strip of paper or take a piece of string.
• Wrap it around the base of your finger—not too loose, not too tight.
• Mark the point where the ends intersect.
• Measure the length in millimeters.
• Use the above men's ring size chart to determine your ring size.

Caution: The String can stretch, and it's easy to wrap it too loosely or too tightly. Verify your measurement, and don't depend on this technique by itself if you wish for an ideal wedding ring fit.

What Other Critical Factors Will Affect Your Ring Size

Even with a correct ring size, other factors can affect how your men's wedding band fits. Here's what you need to consider for the best wedding band fit.

Your Body: Temperature, Diet, and Time of Day

Finger size changes throughout the day. Heat, cold, salty foods, and hydration can all cause your fingers to swell or shrink. An actionable tip is to measure your finger in the late afternoon, when your body temperature is stable and your finger is at its largest “normal” size. This helps avoid a ring that's too tight during daily wear.

The Ring's Width: Why a Wide Band Fits Tighter

A wide men's wedding band (like 8mm) will always feel tighter than a narrow band (like 4mm) of the same size. This is because more metal covers your finger, creating more friction. Here's the rule of thumb: go up a half-size for bands wider than 6mm. Always try on bands in your preferred width to see how they feel.

The Ring's Profile: Comfort Fit vs. Standard Fit

• Standard Fit: Flat on the inside. Sits flush against the skin.
• Comfort Fit: Slightly domed on the inside, which reduces contact with the finger and feels looser.

Most men's wedding bands use a comfort fit. If you're switching from a standard fit to a comfort fit, the same ring size may feel slightly looser. We recommend consulting your jeweler to learn more about the different wedding ring profiles and trying on both styles if possible to ensure you find the perfect fit.

How to Secretly Find His Ring Size

If you plan to buy a man's wedding band as a surprise, that could be tricky, but there are plenty of clever ways to get his ring size without giving away your plans.

• Borrow an Existing Ring: Find a ring he wears on the correct finger and take it to a jeweler, or place it on a men's ring size chart to check the size.
• Ask for Help: Get a close friend or family member to casually ask about his ring size or borrow a ring for you.
• The Sleep Mission: Carefully wrap a piece of string or a strip of paper around his finger while he's asleep. Mark where it overlaps and use a ring size chart to find the size. This method can be tricky, so try not to wake him.
• Trace the Ring: If you can't borrow his ring, place it on a piece of paper and trace the inside and outside with a pencil. Bring this outline to a jeweler for sizing.
• Compare Fingers: Slip one of his rings onto your own finger and note where it fits. A jeweler can measure that spot on your finger to estimate his size.
• Ask About Ring Sizes Casually: Bring up ring sizes in a group conversation or while watching TV, and see if he mentions his size.

A little creativity goes a long way in keeping your surprise safe while making sure his men's wedding band fits perfectly.

What to Do If the Ring Doesn't Fit

Don't worry—it's a common issue with simple fixes. If your men's wedding band size is not ideal, you have choices.

Option 1: Resizing Your Ring

The majority of jewelers are able to resize gold, platinum, or silver rings. Resizing is accomplished by adding or removing a small quantity of metal to change the fit.

• Metals that can be resized: Gold, Platinum, Silver.
• Metals that cannot be resized: Tungsten, Titanium, Ceramic, Cobalt, Wood.

Always inquire with your jeweler regarding resizing possibilities prior to purchasing, particularly if you're looking at alternative metals.

Option 2: Exchanging the Ring

If your men's wedding ring cannot be resized, exchanging it is usually the best solution. Most retailers offer exchanges for non-resizable rings, but policies and time limits differ.

• Always check the store's exchange policy before you make a purchase.
• Save all receipts and packaging in the event that you have to return or exchange your ring.

With Saga Bands, you have 90 days from the date of delivery to exchange your ring. You can change your size, width, and style during this period, making it easy to get the perfect fit.

3 FAQs about Men's Wedding Ring Size

Q1: How should a man's wedding band actually fit?

A: A good fit is when the ring remains on your finger without it feeling as though it's tightening around you. It should go over your knuckle with a bit of a twist and a pull, yet not so readily that it might fly off if you wave your hand. What you're aiming for is security without constant pressure.

Q2: My ring fits perfectly in the morning but is tight at night. Is it the wrong size?

A: That's normal. Your fingers expand and contract throughout the day based on temperature fluctuations, hydration, and activity. Your ring should be slightly looser when it's cold and tighter in warm weather. If it's not painful and isn't constricting blood flow, the size is likely correct.

Q3: I fall between two sizes. Which do I take?

A: Always go with the larger side. A jeweler can add sizing beads to a ring that's a little too large for a snugger fit, but a ring that's too small is impossible to wear. Be patient, use the proper equipment, and hesitate to seek out professional assistance.
