It is necessary to impose your ring on the most suitable stencil, on which the dimensions are indicated. The contour of the stencil must lie exactly along the inner contour of the ring. When choosing between two sizes, choose the largest.

You will need a pen, thread or paper strip about 4 millimeters wide. In this case, the thread should not stretch. Loosely wrap a thread or paper strip around your finger and mark the docking point with a pen. After that, straighten the thread or strip and put it on the size ruler. When choosing between two suitable sizes, choose the larger one.

Cut out the size strip, cut in the designated place, thread the sharp end into the cut - you get a paper ring. Put it on your finger and tighten, but not very tight. The fixed value on the size scale is your ring size.
