How to Measure Your Ring's Inner Diameter

1. Gather Your Tools: Use a digital caliper for the most accurate measurement. If you don’t have one, a clear ruler and a steady hand can work too.
2. Place Your Ring on a Flat Surface: Ensure your ring is on a stable, flat surface for an accurate reading.
3. Measure the Inner Diameter: Gently close the caliper’s jaws until they just touch the inner edges of the ring. Read the measurement in millimeters (mm).
4. Double-Check Your Measurement: Repeat the process a few times to ensure accuracy.

The inner diameter is key for converting to a US ring size.

How to Measure Your Ring's Inside Circumference

1. Tools Needed: A flexible measuring tape or a strip of paper and a ruler.
2. Wrap the Tape or Paper: Wrap it snugly inside the ring without forcing it.
3. Measure the Length: Use a ruler to measure the length in millimeters (mm).

Ensure you measure inside circumference of the ring, not the outside circumference.

How to Measure Your Finger

1. Cut a Piece of String: Take a small piece of string (which is generally more accurate) or a thin strip of paper that’s long enough to wrap around your finger.
2. Wrap It Around Your Finger: Wrap the string around the base of your finger where you plan to wear your ring. Ensure it’s snug but not too tight.
3. Mark the Spot: Use a pen or marker to mark where the string meets its starting point.
4. Measure the String: Lay the string flat and measure its length in millimeters (mm). This is your finger’s circumference.
5. Convert Your Measurement: Use the ring sizing chart below or the conversion tool above to determine your US ring size.

The string method is quick and cost-effective. For maximum accuracy, consider professional sizing.
