How to Measure Your Ring Size at Home
Use one of these simple methods to measure your ring size accurately. For the best results, measure in the evening when your fingers are slightly larger, and ensure the ring can slide over your knuckle comfortably.
Method 1: Paper Strip Method
- Cut a thin strip of paper (about 1/4 inch wide) and wrap it snugly around your ring finger.
- Mark where the paper overlaps with a pen.
- Measure the length from the start of the paper to the mark using a ruler with millimeter (mm) measurements.
- Compare the measurement to the ring size conversion chart below to find your size.
Tip: Measure twice to ensure accuracy. If your measurement falls between sizes, choose the larger size.
Method 2: Printable Ring Sizer
Download our free printable ring sizer and follow these steps:
- Print the guide with page scaling set to 100%.
- Place a ring you already own over the circles on the guide.
- Match the inside edge of the ring to the closest circle size (based on inside diameter).
- If the ring is between two sizes, opt for the larger size.
Note: Wider bands may feel tighter, so consider going up a half size for comfort. For precise sizing, visit a local jeweler.
