Step 1: Preparations

Before you measure your finger there are a few things you must keep in mind:

Measure your finger at the end of the day when it is the largest, as our fingers change sizes throughout the day.
Measure your finger three to four different times as the size changes depending on temperature- your finger can shrink or expand when hot or cold.
Make sure you leave enough room to accommodate your knuckle.

Step 2: Wrap Paper

Cut a strip of paper to be about 8 inches long and 0.5 inches wide.
Wrap the paper close to your knuckle, as this is the thickest part of your finger, making sure not to wrap it too tight, to assure it will be a fit that is comfortable.
Make sure that to measure the finger that you would like your ring to sit on. Use a pencil or pen to mark where the strip forms a complete circle and begins to overlap.

Step 3: Measure

Use your ruler to measure from the edge of the paper to the line marked, remember to measure up to the nearest millimeter, this is the circumference of your finger. Record your measurement on a separate piece of paper.
