How to Measure Your Ring Size at Home
No jeweler needed — a few easy methods to find your ring size accurately.
Buying a ring online? Getting the size right is easier than you'd think. Here are reliable ways to measure at home, plus tips to make sure your number is accurate.
Method 1: Measure a ring you own
Take a ring that already fits the correct finger and measure the inside diameter in millimeters. Compare it to a ring size chart to find your size — one of the most accurate home methods.
Method 2: The string or paper strip
Wrap a strip of paper or string around the base of your finger, mark where it overlaps, and measure the length in millimeters. That's your finger's circumference — match it to a size chart.
Tips for accuracy
Measure at the end of the day when fingers are largest, in a warm room (cold shrinks fingers), and a few times for consistency. Make sure the size clears your knuckle comfortably.
