Getting ready to take the plunge and order that ring you’ve been eyeing? Good for you! The narrowing-down is always the hard part. But you’re not done yet. Now you’ve got to think about sizing. Getting your ring size right the first time can save you a ton of disappointment, headache and back and forth. But it’s not the end of the world if you don’t get it right up front, at least if you shop at Modern Gents where returns and exchanges are a breeze. With that said, we’re here to help you measure your finger the easy way.
Understanding How Rings Are Measured
The good news is that there’s no real science to ring measuring and pretty much anyone can do it at home. In the U.S. and Canada, ring sizing follows a scale ranging from 0.5 to 14. This is the measurement standard for US ring sizes. You must measure the circumference of your finger — preferably in millimeters — and then use that measurement to find your coordinating ring size according to the U.S. and Canadian standard. Note that all Modern Gents rings are made to U.S. and Canadian standard ring sizes.
If you’re ordering from another country or an international brand, take note that sizing systems can vary widely. The UK, Europe, and Asia all have their own sizing conventions, which could easily cause confusion. Always double-check which sizing system your retailer uses and consult their conversion charts. Knowing this ahead of time can save you unnecessary returns and ensure your new ring fits like a glove, whether it’s coming from down the street or across the globe.

How to Measure Ring Size Without a Ring
The easiest and most effective way to get your ring size at home is to measure your finger using a piece of string, floss or a ribbon. If you’re in a pinch, a slim strip of paper will work, too. This is the best method if you don't have a ring that fits the finger you're shopping for. You’ll also need a pen and a ruler or measuring tape. Here’s how to do it:
-
Wrap a piece of loose, thin string or ribbon around the base of your finger. This is a critical step, so make sure you choose the best finger for ring size measurement (usually the one you plan to wear the ring on). Wrap tightly so there’s no slack at all in the string.
-
Use a sharpie or a dark pen to mark where the ends meet.
-
Using a ruler, measure the distance between your pen marks and record it in millimeters. This is the circumference of your finger.
-
You can now use a ring size chart to translate the circumference of your finger into your standard U.S. ring size.
-
You know what they say: Measure twice, cut once! Just to be double-sure, repeat the process. If you get a different number, do it one more time.
How to Use an Existing Ring to Measure Size
If you already have a ring that fits your intended finger perfectly, you can use that existing ring to measure your size. This is a great way to ensure a comfortable fit.
-
Find a printable ring sizer at home. There are many available online that you can download and print. Make sure to print it at 100% scale.
-
Place your ring over the circles on the chart. Find the circle that perfectly matches the inside edge of your ring without any overlap.
-
The number associated with that circle is your ring size. You can also use an online ring sizer tool, which often works in a similar way using your screen.
When using physical tools, don’t forget to take into account the width and style of the ring you're measuring against. A wide band may feel tighter than a slender one, and certain designs can influence comfort. If you’re comparing a ring that isn’t the same width as what you plan to purchase, adjust your final size appropriately.
Tip #1: It’s Generally Wiser to Size Up
With rings, should you size up or size down? It depends, but, in general, it’s a good idea to size up on rings. That’s because it’s a bit trickier to resize rings that are too small. As you can imagine, it’s easier for a jeweler to take material out than add material in, so we’d recommend jumping up a size if you’re on the cusp.

Tip #2: See a Professional
If you’re worried about finding the right fit, you can always stop in at your local jeweler and have your finger professionally measured. Jewelers have special ring-sizing devices that will provide a perfect fit. You can also purchase a ring sizer tool online relatively cheaply to keep at home.
For those purchasing wedding rings or expensive statement pieces, investing in a reliable sizer might be a smart move for lasting accuracy.
Tip #3: Measure at the Right Time of Day
You’ve probably noticed the change in finger size during the day, and that’s totally normal. What you eat, the time of year and the weather can have a huge effect on how your ring fits throughout the day. Make sure you measure at a time when your finger is not shrunken or swollen. For many people, ring size is the most stable in the afternoon or evening.
Another good trick is to avoid measuring your fingers when you’re extremely cold or right after physical activity. Both situations can cause temporary swelling or shrinkage that throws off your measurement, so try to measure in comfortable, room-temperature conditions when you’re relaxed.
Tip #4: Consider Your Knuckle
When measuring, you need to think about your knuckle size vs. base size. If your knuckle is significantly larger than the base of your finger, you’ll need a size that can slide over the knuckle without being too loose at the base. Measure both your knuckle and the base of your finger, and choose a size that’s somewhere in between.
Tip #5: Account for Wide Bands
Wide band ring sizing is crucial because wider rings fit more snugly than thinner ones. If you're buying a ring with a band wider than 6mm, we recommend sizing up by a quarter to a half size to ensure a comfortable fit.
