When it comes to purchasing rings, whether as a gift or for personal use, knowing the correct ring size is crucial. An ill-fitting ring can lead to discomfort or, worse, can become lost. This guide is designed to provide you with thorough and reliable information on how to determine ring size in centimeters. You’ll find methods, tips, and additional considerations to help you nail down the perfect fit.
Understanding Ring Sizes
Before diving into how to measure ring size, it’s important to understand what ring sizes are and where they come from.
- Ring sizes are numeric values that help classify the circumference of a ring.
- Measurements can be expressed in different units; while some countries use inches (US and UK), others use centimeters (Canada, Europe).
Common Ring Size Charts
In many regions, ring sizes correlate to a standard chart. Here’s a quick overview:
- US Sizes: Typically numerical, starting from size 3 and going up to size 13.
- European Sizes: Often listed in millimeters or centimeters, using a different numbering system (e.g., 45 for size 3, 70 for size 15).
- Asian Sizes: Commonly measured in millimeters, similar to European sizes.
Importance of Knowing the Correct Size
- Comfort: The right size ensures comfort throughout the day.
- Security: A properly sized ring is less likely to slip off.
- Aesthetic: A ring that fits well enhances your overall look.
Tools You Will Need
Before measuring for your ring size, gather the following tools:
- A flexible measuring tape (in centimeters)
- A strip of paper or a thin string (if no measuring tape is available)
- A ruler (for more accurate measurement)
- A ring sizer (optional, can be purchased or borrowed)
How To Measure Ring Size in Cm
The following methods outline how to measure your ring size accurately. Choose the one that’s most convenient for you.
Method 1: Measuring With a Measuring Tape
- Wrap the Tape: Take the flexible measuring tape and wrap it around the base of your finger.
- Note the Size: Make sure the tape is snug but not too tight. Mark where the tape overlaps.
- Read the Measurement: Read the measurement in centimeters.
Important Tips:
- Ensure your finger is at normal body temperature; cold fingers shrink, and hot fingers expand.
- Measure multiple times throughout the day for the most accurate reading.
Method 2: Using String or Paper
- Cut the String: Cut a strip of paper or a piece of string about 15 cm long.
- Wrap Around Finger: Wrap the paper or string around the base of your finger.
- Mark the Overlap: Mark the point where the string or paper meets.
- Measure Against a Ruler: Lay the string/paper flat and measure the length up to the mark using a ruler.
Method 3: Using a Ring Sizer
- Obtain a Ring Sizer: If you have access to a professional ring sizer, use it to determine your size.
- Choose Your Size: Slide different rings onto the sizer until you find the one that fits comfortably.
Method 4: Measuring an Existing Ring
If you have a ring that fits your desired finger well, you can use it for measurement.
- Measure Diameter: Place the ring on a flat surface and use a ruler to measure the inner diameter of the ring from one inside edge to the other.
Convert It to Circumference: Use the formula:
- Circumference (cm) = Diameter (cm) × π (approximately 3.14).
- Determine Size: Use this measurement as reference to consult size charts available online.
Common Mistakes to Avoid
- Wrong Time of Day: Avoid measuring your finger in extreme temperatures. Ideal times are in the evening when your fingers are at their largest.
- Tight or Loose Fit: Rings should slide on easily but shouldn’t be loose enough to come off without a gentle tug.
- Not Considering Knuckles: If you have larger knuckles, consider that when sizing, sometimes opting for a slightly larger size is necessary.

When To Get Help from a Jeweler
If after all your measurements, you’re still unsure about the size, it may be best to visit a jeweler. A professional can easily size your finger accurately and let you try on different styles.
