How to Find Your Ring Size at Home: The Complete Guide
Buying a ring online or preparing for a surprise proposal? Knowing the right ring size is essential to make sure the ring fits perfectly and comfortably. The good news is, you don’t need to go to a jeweler to find out your ring size. You can do it easily from home with just a few common items and a little patience.
In this article, I’ll explain how to find your ring size at home, covering multiple methods in both centimeters and inches. Whether you’re shopping for yourself or planning a surprise gift, you’ll find everything you need here.
Use a String or Paper Strip to Measure Your Finger
One of the easiest and most popular ways to find your ring size at home is by using a piece of string or a strip of paper. This method doesn’t require any special tools and gives fairly accurate results when done carefully.
Here’s how you do it:
- Cut a piece of string or paper strip about 10-12 cm (or 4-5 inches) long.
- Wrap it around the base of the finger where you plan to wear the ring.
- Make sure the string fits snugly but not too tight.
- Mark the point where the string or paper overlaps using a pen or marker.
- Lay the string or paper flat on a ruler and measure the length in centimeters (cm) or inches.
This measurement gives you the circumference of your finger. Use a ring size chart to convert that into a ring size. For example, a circumference of 5.4 cm (2.13 inches) typically corresponds to a US ring size 7.
If you’re wondering how to find your ring size at home in cm or in inches, this is the best method to start with. Just remember to take the measurement a couple of times and average the results to be more accurate.
Measure an Existing Ring That Fits Well
If you already own a ring that fits perfectly on the intended finger, you can use it to determine the correct ring size. This method is fast and reliable, especially if the ring has a round shape and isn’t bent.
Here’s what to do:
- Place the ring on a ruler and measure the inner diameter of the ring in millimeters (mm) or inches.
- Don’t include the metal thickness—just the inside edge to inside edge.
Once you have the diameter, use a ring size chart to match it to the correct ring size.
For example:
- An inner diameter of 17.3 mm (0.68 inches) corresponds to US size 7.
This is a great option if you’re shopping for someone else and you can borrow a ring they already wear on the correct finger.
Use a Printable Ring Size Chart
Many jewelry websites offer printable ring size charts that make it super easy to find your size. These charts typically include:
- A circle guide where you place an existing ring over the circles until it matches one exactly.
- A measuring strip that you can cut out and wrap around your finger.
Make sure to print the chart at 100% scale (do not scale to fit), or it will give incorrect results. Double-check the scale by measuring the calibration line on the chart with a ruler.
This method is especially useful if you’re trying to confirm your size after using the string method.
Ring Size Conversion Chart (cm and inches)
Use the table below to convert finger circumference measurements into common ring sizes:
| Circumference (cm) | Circumference (inches) | US Ring Size |
|---|---|---|
| 4.6 | 1.81 | 3 |
| 4.9 | 1.93 | 4 |
| 5.2 | 2.04 | 5 |
| 5.4 | 2.13 | 6 |
| 5.7 | 2.24 | 7 |
| 6.0 | 2.36 | 8 |
| 6.3 | 2.48 | 9 |
| 6.5 | 2.56 | 10 |
| 6.7 | 2.64 | 11 |
This table helps answer both how to find your ring size at home in cm and how to find your ring size at home in inches. Measure your finger’s circumference and look up the matching size.
Ring Diameter to Size Chart
Here’s another helpful table if you are measuring the diameter of an existing ring:
| Inner Diameter (mm) | Inner Diameter (inches) | US Ring Size |
|---|---|---|
| 14.1 | 0.56 | 3 |
| 14.8 | 0.58 | 4 |
| 15.7 | 0.62 | 5 |
| 16.5 | 0.65 | 6 |
| 17.3 | 0.68 | 7 |
| 18.1 | 0.71 | 8 |
| 19.0 | 0.75 | 9 |
| 19.8 | 0.78 | 10 |
| 20.6 | 0.81 | 11 |
Always measure at least twice to ensure accuracy. Small differences in diameter make a big difference in the fit.
Tips to Get Accurate Results
Getting your ring size right is important, and small errors can lead to a tight or loose fit. Use the tips below to make sure your measurement is as accurate as possible:
- Measure your finger at the end of the day. Fingers swell slightly throughout the day.
- Make sure your hands are warm. Cold fingers are thinner, which can result in a ring that feels too tight later.
- Measure multiple times. Take 2-3 measurements and use the average.
- Consider your knuckle size. If your knuckles are large, choose a slightly bigger size so the ring can slide over them.
- Don’t pull the string too tight. You want the ring to be snug, not squeezing.
Following these tips will improve your chances of getting the perfect fit the first time.
Common Mistakes to Avoid When Measuring at Hom
Avoid these common pitfalls when measuring your ring size at home:
- Using stretchy materials (like elastic or thread) that give inaccurate results.
- Not measuring the correct finger. Each finger is slightly different.
- Using a ring that’s out of shape to measure diameter.
- Relying on just one method. Always verify with at least one other method.
- Guessing the size. Even a small size error can make the ring uncomfortable or unwearable.
These mistakes are easy to avoid and can save you from resizing hassles later.

FAQs
1. How can I find my ring size at home accurately?
You can find your ring size at home by using a string, a strip of paper, or a printable ring sizer. Measure the circumference of your finger or the diameter of a well-fitting ring, then compare the results with a ring size chart.
2. How to find your ring size at home in cm?
Wrap a string or paper around your finger and measure the length where it overlaps using a ruler in centimeters. Then, use a ring size chart to convert that measurement to your ring size.
3. How to find your ring size at home in inches?
Just like measuring in centimeters, wrap a string or paper around your finger and use a ruler to measure the length in inches. Then, use a size chart that includes inch-to-size conversions.
4. Can I find out my ring size at home without any tools?
While it’s best to use a ruler and string, some online tools and apps can help you estimate your size. However, physical measurement is more reliable for accuracy.
5. How do I know if I measured my ring size correctly?
Double-check by measuring more than once and using different methods. Also, compare your results with a reliable ring size chart. Consistent results across methods usually mean you’ve measured correctly.
6. What time of day is best for measuring ring size?
The best time to measure is at the end of the day when your fingers are warm and slightly swollen. Measuring in the morning or when you’re cold can lead to a size that’s too small.
7. What if I’m between two ring sizes?
If you’re between sizes, it’s safer to go one size up. A slightly looser ring is more comfortable and can be adjusted more easily than a tight one.
8. How tight should a ring fit?
A ring should slide over your knuckle with a little resistance and sit snugly on your finger without spinning. It should not cause discomfort or leave deep marks.
9. Can I use a phone app to find my ring size?
Some apps let you measure a ring by placing it on your screen, but results vary by phone and screen size. Always confirm app-based results with a physical method.
10. Can rings be resized if I get the wrong size?
Yes, most rings can be resized by a jeweler. However, resizing has limitations depending on the material and design. Getting the right size first is always better.
