Let me share something fun—my friend Emma decided to measure her ring size at home with just a piece of string and a ruler. She was a bit unsure at first, but it worked like a charm, and the ring fit perfectly!
If you’re curious about the costs associated with resizing rings later, check out this helpful guide on how much it costs to size a ring. But for now, let’s dive into how you can find your exact ring size!
Why Measuring in CM is a Game-Changer
Let’s be real—when it comes to rings, every millimeter counts. A slight difference can mean the ring feels too tight or keeps slipping off. That’s why measuring in centimeters is such a smart move. It’s precise, easy, and works like a charm, especially if you’re dealing with international ring sizes.

Here’s why measuring in cm is the way to go:
- Accuracy matters: Measuring in centimeters gives smaller, more precise units compared to inches, ensuring the perfect fit.
- Ideal for online shopping: If you’re buying rings from an international retailer, cm measurements are often the standard.
- DIY-friendly: You don’t need special tools—a simple string, paper, and ruler are enough.
Even the Gemological Institute of America (GIA) emphasizes precision when measuring for rings, stating, “Proper sizing is essential for both comfort and ensuring the ring stays secure on your finger.”
And if you’re planning to size your ring down the road or get it appraised, you might find it helpful to understand the importance of a ring appraisal for its value and future adjustments.
Whether it’s your first ring or a meaningful upgrade, measuring in cm guarantees you’ll get it right without relying on guesswork!

What You’ll Need Before You Start
Before you dive into measuring your ring size in cm, make sure you have everything you need ready. Trust me, it’s super easy when you’re prepared! Here’s a quick checklist:
- A string, strip of paper, or measuring tape: This is what you’ll use to wrap around your finger.
- A pen or marker: Use this to mark the point where the string or paper overlaps.
- A ruler marked in centimeters: You’ll use this to measure the length of the string or paper accurately.
- (Optional) A ring size chart: This is handy for converting your cm measurement into a standard ring size.

The String Method: Simple and Effective
The string method is one of the easiest and most cost-effective ways to measure your ring size at home. With just a few household items, you can get an accurate measurement and ensure your ring fits perfectly. Let’s go step by step to help you nail this process.
Steps to Measure Ring Size with String
- Choose a non-stretchy string: Select a thin, non-elastic string like embroidery thread or dental floss for the most accurate results.
- Wrap the string around your finger: Place the string at the base of your finger (where the ring will sit). Ensure it’s snug but not too tight.
- Mark the overlap point: Use a pen or marker to note where the string overlaps itself.
- Flatten the string: Lay the string flat on a ruler or measuring tape.
- Measure the string in cm: Take the length from the start of the string to the marked point, and record the measurement.
- Use a detailed chart for size conversion: Match your measurement to a chart that includes US, UK, European, and Asian sizes.
Pro Tips for Accurate Measurement
- Measure at the right time: Fingers swell throughout the day, so measure in the evening for the best fit.
- Avoid cold or hot conditions: Cold fingers shrink, while heat may cause them to swell. Measure at room temperature.
- Double-check for accuracy: Repeat the process at least twice to confirm your results.
According to the Gemological Institute of America (GIA), “Ring sizing should prioritize both comfort and functionality, ensuring the ring fits snugly without being difficult to remove.” For added security, measure the widest part of your finger, including the knuckle.

Why This Method Works
This method is perfect for:
- DIY enthusiasts: No need for professional tools.
- International buyers: Measurements in cm can be easily converted to international sizes.
- Budget-conscious shoppers: It’s free and accurate.
The Paper Strip Method: Another Easy Option
If you don’t have string available, a strip of paper works just as well. This method is reliable, quick, and provides the precision needed to ensure your ring feels comfortable all day long.
Steps to Measure Ring Size with a Paper Strip
- Cut a thin strip of paper: Use a piece about 1 cm wide and long enough to wrap around your finger.
- Wrap the paper around your finger: Place the strip at the base of your finger, ensuring it’s snug but not tight.
- Mark the overlap point: Use a pencil or pen to note where the paper meets itself.
- Flatten the paper strip: Lay the strip flat on a ruler or measuring tape.
- Measure the length in cm: Record the measurement from the start of the strip to the marked point.
- Match your measurement: Use a size conversion chart to find your perfect ring size.
Quick Tips for Accurate Results
- Avoid glossy paper: Slippery or shiny paper can shift while measuring. Stick to plain paper.
- Keep the paper flat: Ensure no folds or creases distort the measurement.
- Check multiple times: Repeat the process to verify your result.
The American Gem Society (AGS) advises, “Ring sizes should be determined with precision to avoid resizing, which can weaken certain types of rings.” This method is especially helpful for delicate settings like moissanite or diamond solitaires.
Why This Method is Great
The paper strip method works well because:
- It’s accessible: Most people already have paper and rulers at home.
- It’s simple: No need for complicated tools or devices.
- It’s accurate: When done correctly, it provides results comparable to professional ring sizers.

How I Measured My Ring Size in CM
I still remember the first time I had to measure ring size in cm—it was for my sister’s engagement ring. She had her eye on a beautiful solitaire, but we didn’t have a professional ring sizer on hand. So, we decided to go with the string method.
It felt a bit like a DIY project at first. We carefully wrapped a piece of string around her finger, making sure it wasn’t too tight or too loose. Then, we marked the overlap point, measured it with a ruler, and matched the length to a ring size chart.
To be extra sure, we repeated the process a couple of times. Each measurement matched perfectly! When the ring arrived, it slid on her finger like it was made just for her. Honestly, the relief and joy on her face made all the effort worthwhile.
Mehedi Hasan, an expert gemologist from Aurelia, often emphasizes the importance of precision in sizing, saying, “Even a small mistake in measurement can affect comfort and security, so it’s always wise to double-check your results.” His advice gave us confidence in our approach, ensuring my sister’s engagement ring became a flawless fit without any need for resizing.
This experience taught me two things:
- Measuring in cm is accurate and reliable when done correctly.
- Taking the time to double-check measurements saves a lot of stress later.
If you’re ever in doubt about the best method to measure your ring size, remember that simple tools like string or paper, combined with expert tips, can make all the difference. It’s an easy process with results you can trust!
FAQs: All Your Questions Answered
Q. Can I measure ring size without a ring sizer?
Ans. Absolutely! You don’t need a professional ring sizer to measure your ring size accurately. Here are a few alternatives:
- String method: Use a non-stretchy string to wrap around your finger, then measure the length with a ruler.
- Paper strip method: A thin strip of paper works just as well; just make sure it’s snug.
- Use an existing ring: Measure the inner diameter of a ring you already own and compare it to a size chart.
- Printable ring sizers: Many jewelers provide free printable ring sizer templates online.
With these easy methods, you can confidently measure your ring size at home!
Q. What if my size is between two measurements?
Ans. If your size falls between two measurements, here’s what you should do:
- Always choose the larger size for comfort, especially if the band is wider.
- For thinner bands, the smaller size might still fit snugly without being uncomfortable.
- Consider your knuckles—if they’re larger than the base of your finger, the larger size will be easier to slide on and off.
Choosing the right size ensures your ring feels comfortable all day long!
Q. How do I find a ring size chart?
Ans. Ring size charts are widely available and can make sizing so much easier. Here’s how to find one:
- Ask your jeweler: Most jewelers provide detailed ring size charts for free.
- Search online: Look for trusted sources like the GIA or the American Gem Society.
- Printable versions: Download and print a chart to measure an existing ring at home.
Using a chart helps you match your measurement to the correct size effortlessly.
Q. Does finger size change throughout the day?
Ans. Yes, your finger size can vary depending on several factors:
- Time of day: Fingers are usually larger in the evening due to natural swelling.
- Temperature: Heat causes fingers to expand, while cold makes them shrink.
- Activity level: Physical activity and hydration levels can temporarily affect finger size.
For the most accurate measurement, size your finger in the evening at room temperature.
Q. Can I measure someone else’s size secretly?
Ans. Measuring someone else’s ring size without them knowing is possible. Here’s how:
- Use an existing ring: Borrow a ring they wear on the intended finger and measure its inner diameter.
- Trace the ring: Place their ring on a piece of paper and trace the inner circle, then measure it.
- Enlist help: Ask a trusted friend or family member to subtly gather the information for you.
These tricks can help you surprise someone with a perfectly sized ring!
