If a ring is too small it won't fit over your knuckle, and if it's too big it won't stay on your finger when you start to slow clap after a dog wins a basketball tournament. Find your ring size using one of the below methods.
Method 1: How to Measure Ring Size Using a String or Strip of Paper and a Ruler (No Printer Required)
- Ruler with millimeter measurements
- Non-stretchy string / strip of paper
- Wrap a piece of non-stretchy string or strip of paper around the base of your finger
- Mark the point where it overlaps using a pen or fine-point marker
- Measure the length in millimeters using a ruler
- Compare the length to the ring-size chart below to determine your ring size
- All measurements match the inside circumference of the ring
- If your finger measurement falls between sizes, order the larger size.
- Fingers, like brains, are smaller in the morning and bigger by the end of the day. Measure your fingers at the end of the day.
- Take multiple measurements to ensure an accurate reading.
- Weather and temperature affect finger size. Do these measurements where it's moderately warm.
- If you have large knuckles, measure both the base of your finger and your knuckle and select a size between the two.
- Fingers tend to be one half-size larger on your dominant hand
Method 2: How to Measure Ring Size by Comparing a Ring That Fits to a Printed Diagram (Printer Required)
