Rubber Band Size Numbers
A rubber band is assigned an industry-standard number based on its dimensions. Most people are not familiar with this numbering system.
Generally, rubber bands are numbered from smallest to largest, with width first. Thus, rubber bands numbered 8–19 are all 1⁄16 inch wide, with lengths going from 7⁄8 inch to 3-1⁄2 inches. Rubber band numbers 30–35 are for widths of 1⁄8 inch, going again from shorter to longer. For even longer bands, the numbering starts over for numbers above 100, again starting at width 1⁄16 inch.
