Why an Accurate Ring Size Measurement Matters So Much

Hi, I’m Sarah! I’m not a professional jeweler, but I’m a huge jewelry lover. Over the years, I’ve helped countless friends and family secretly find a ring size for engagement proposals and birthday gifts. I’ve also ordered my fair share of rings online and learned the hard way what happens when you guess your ring size measurement. (Hint: it involves a ring getting stuck or, worse, slipping off!).

After you get an accurate ring size measurement, a ring that fits perfectly feels like it’s a part of you. It doesn’t pinch, slide around, or get in the way. It just feels right. That’s why I put together this simple guide on how to measure ring size. I want you to feel confident and excited about your next ring purchase.

How to Measure Your Ring Size: 3 Easy Methods

Here are three reliable ways for measuring ring size. For the best results, I recommend trying at least two methods and comparing them to get the most accurate result.

Method 1: The String or Paper Method (Most Common)

This is the classic DIY method if you want to know how to measure your ring size with household items. All you need is a piece of non-stretchy string or a thin strip of paper, a ruler, and a pen.

Step-by-Step Instructions:

1. Wrap It Up: Wrap It Up: The first step in how to measure ring size with this method is to take a piece of non-stretchy string (about 6 inches long and 1/4 inch wide). Wrap it snugly around the base of the finger you want to measure. It should be snug, but not uncomfortably tight.
2. Mark the Spot: Use a pen to mark the point where the end of the string or paper overlaps, forming a complete circle. This is a crucial step for an accurate ring size measurement.
3. Measure the Length: Straighten out the string or paper and use a ruler with millimeter markings to measure the length from the end to your pen mark. This is the circumference of your finger.
4. Find Your Size: Write down the measurement in millimeters (mm). Now, use the ring size chart below to convert your ring size measurement into a standard US ring size.

Ring Size Conversion Chart (Circumference)

Measurement (mm)	US Ring Size
49.3 mm	5
50.6 mm	5.5
51.9 mm	6
53.1 mm	6.5
54.4 mm	7
55.7 mm	7.5
57.0 mm	8
58.3 mm	8.5
59.5 mm	9
60.8 mm	9.5
62.1 mm	10

Method 2: The Existing Ring Method (Easiest)

If you want to measure ring size using something you already own, this method is for you. It’s fast, easy, and very accurate if you have a ring that already fits the intended finger perfectly.

Step-by-Step Instructions:

1. Find a Perfect Ring: Choose a ring that fits the correct finger comfortably. This is the simplest way to find your ring size without any wrapping or marking.
2. Measure the Inside: Measure the Inside: A key part of how to measure ring size this way is to place the ring on a ruler and measure the inside diameter in millimeters. Make sure you are measuring the widest part of the ring, from one inner edge to the other.
3. Use a Chart: Compare your diameter measurement to an online ring size chart. This confirms the correct ring size measurement from your existing ring.

Method 3: The Printable Ring Sizer Method (Most Accurate DIY)

This is another great way to measure ring size and it removes some of the guesswork. You can print a to-scale ring sizer chart to get a reliable result.

Step-by-Step Instructions:

1. Find and Print a Chart: Search online for a “printable ring size chart.” Make sure to print it at 100% scale. This step is critical if you want this method of measuring ring size to work.
2. Verify the Scale: This is a critical step if you want to know how to measure ring size accurately; use a physical ruler to check the scale. Use a physical ruler to measure it and confirm the printout is the correct size.
3. Use the Sizer: Use the cut-out sizer on the chart to wrap around your finger. The arrow will point to your size, giving you an easy way to find your ring size.

7 Helpful Tips for an Accurate Ring Size Measurement

Getting the right size is about more than just technique. Here are some pro tips for anyone learning how to measure ring size.

1. Measure at the End of the Day: Your fingers naturally swell slightly. Measuring in the evening will give you the most accurate ring size measurement.
2. Temperature Matters: This is a key factor in how to measure your ring size, as cold hands can shrink. An accurate attempt at measuring ring size requires normal body temperature.
3. Don’t Forget the Knuckle: If you have larger knuckles, when you measure your ring size, measure both the base of your finger and your knuckle, then choose a size in between.
4. Measure Multiple Times: For the best result, repeat your ring size measurement 3-4 times on different days to find the most consistent number.
5. Consider the Band Width: A wider band will feel tighter. Consider going up a half size. This is an important factor in how to measure your ring size correctly for different styles.
6. When in Doubt, Size Up: It’s easier to size a ring down than up. If you’re stuck between two sizes, choose the larger one.
7. Check International Sizing: Always confirm which country’s sizing standard you are using, as it’s a key part of how to measure ring size for international jewelry.

Common Mistakes When Measuring Ring Size

When you’re learning how to measure ring size, it’s easy to make a small error. Avoid these common slip-ups:

• Using a Stretchy String: Avoid this at all costs when learning how to measure ring size. Elastic or stretchy string will give you an incorrect, smaller measurement.
• Pulling Too Tight: The sizer or string should be snug. How tightly you pull is a key detail for an accurate ring size measurement.
• Measuring Once: Your finger size fluctuates. Relying on a single measurement is a risky way to find your ring size.
• Forgetting to Check Print Scale: A printable chart that isn’t printed at 100% is useless. Always double-check.

Troubleshooting: When How to Measure Ring Size Goes Wrong

So you’ve followed the steps on how to measure your ring size, but you’ve hit a snag. Don’t worry! Here are solutions to the most common issues people run into.

Problem 1: Your measurement is between two sizes.

This is a common outcome for those learning how to measure ring size; it can be confusing whether to size up or down.

• The Solution: When in doubt, it’s almost always better to choose the slightly larger size. It is much easier and cheaper for a jeweler to make a ring smaller than to make it larger. If the ring you want has a wide band (thicker than 6mm), you should definitely choose the larger size, as wider bands fit more snugly.

Problem 2: A ring fits over your knuckle, but then spins or feels loose at the base of your finger.

This is a common issue for people with larger knuckles. You need a size that can get over the knuckle but doesn’t feel like it will fall off.

• The Solution: Ask a jeweler about adding “sizing beads” or a “sizing bar” to your ring. These are two small metal bumps placed on the inside of the band. They anchor the ring at the base of your finger to prevent spinning, without changing the actual ring size. It’s a simple, comfortable, and affordable fix.

Problem 3: You need to find someone else’s ring size for a surprise.

This is the ultimate challenge in measuring ring size! Getting it right without them knowing requires a bit of detective work.

• The Solution: The most reliable method is to secretly borrow a ring they already wear on the correct finger and use our “Existing Ring Method.” If you can’t sneak the ring away, try a spy trick: when they aren’t looking, press the ring firmly into a bar of soap to create a clear impression. You can also discreetly trace the inside of the ring onto a piece of paper with a very sharp pencil. For even more clever ideas, the Gemological Institute of America (GIA) offers excellent tips on finding a ring size in secret.

Problem 4: The ring you are using for reference is a “Comfort Fit” band.

You might be using a ring that fits perfectly to find your size, but not all bands are created equal.

• The Solution: A “comfort fit” ring is domed on the inside, which makes it feel looser and slide on more easily. A “standard fit” ring is flat on the inside. If your reference ring is a comfort fit, a new standard fit ring in the same size will feel much tighter. When using a comfort fit ring as your guide for a standard fit purchase, a good rule is to subtract a quarter to a half size from your measurement.
