Rubber bands are sized using a numbering system, where the number generally indicates both the width and length of the band. The smaller the number, the smaller the band; generally, numbers increase as size increases, but understand that the numbers relate to a combination of width and length, not just one dimension.
Here's a breakdown:
-
Numbering System: Rubber bands are numbered, and these numbers relate to their dimensions (width and length).
-
Width: Rubber bands are often categorized by their width, which is frequently expressed in fractions of an inch. For instance, rubber bands numbered 8-19 usually have a width of 1/16 inch. Rubber bands numbered 30-35 usually have a width of 1/8 inch.
-
Length: Within each width category, the numbers typically increase with length.
-
Example: Rubber bands numbered 8 through 19 all have a width of 1/16 inch, but their lengths increase from 7/8 inch to 3-1/2 inches. Similarly, bands numbered 30 through 35 are 1/8 inch wide and vary in length.
In summary, rubber band sizes are indicated by a number that reflects both width and length. Larger numbers typically mean larger rubber bands overall. While the system can seem a bit abstract, understanding the interplay between width and length is key to selecting the right size for a specific application.
