what size rubber bands teeth
Generally, rubber bands are numbered from smallest to largest, width first. Thus, rubber bands numbered 8â19 are all 1/16 inch wide, with lengths going from 7/8 inch to 3 1â2 inches. Rubber band numbers 30â34 are for width 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. The origin of these size numbers is not clear and there appears to be some conflict in the standard numbers.
