Bead Size

The size of a bead is usually measured in millimeters, and charts often convert to inches using decimals. If you have trouble visualizing bead size in those measurements, perhaps my conversion tables will help you.

I have converted to the closest eighth of an inch.

Another way to help visualize the millimeter size of a bead is to look at a ruler that has inches along one edge and millimeters, or centimeters, along the opposite edge.
