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)

Supplies Needed

• Ruler with millimeter measurements
• Non-stretchy string / strip of paper

Instructions

1. Wrap a piece of non-stretchy string or strip of paper around the base of your finger
2. Mark the point where it overlaps using a pen or fine-point marker
3. Measure the length in millimeters using a ruler
4. Compare the length to the ring-size chart below to determine your ring size

Measuring Tips

• 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
