Method 2 – Measuring your fingers
Cut a strip of paper or ribbon long enough to wrap around your finger.
Wrap it around the largest part of your finger.
Use a pen to mark the point where it forms a circle.
Using a ruler, measure the distance from the end of the strip of paper to the mark you made.
Compare your measurement with the chart below to determine your ring size.
Tip: Your fingers become smaller in cold temperatures so never measure cold fingers. Measure your fingers at the end of the day which is when they are usually at its largest.

MIDI RING SIZING
A general rule of thumb is that a midi ring will be 3-4 sizes smaller than your normal size. For example, if you are a size 7 on your middle finger, you should take a size 4 in midi ring. However, it is always best to measure your own fingers to be sure.
