When purchasing rubber bands, you may have noticed a size number that corresponds to the length, width, and thickness of the rubber band. How these sizes came about we don’t know (the Rubber Band Olympics of 1845 is our guess), but they are helpful when identifying the many different sizes. Below is a rubber band sizing chart that will be helpful when placing your next rubber band order! But first, let’s take a look at how they are measured.

LengthHalf of its circumference.

Width – The distance from one edge to the other.

Thickness – The distance from the inner circle to the outer circle.

Aside from the basic rubber band, there are a few specialties. Ergonomically correct rubber bands are easy to stretch. You can also find latex-free rubber bands, corner-to-corner rubber bands, X-treme file bands (remarkably durable), and extra large rubber bands. There are colored rubber bands and packs with assorted sizes. And of course, the rubber band ball is also available. Have a question about rubber band sizing? Please ask! We are always happy to help!

Did you know? Rubber bands last longer when refrigerated-don’t mistake them for spaghetti noodles the next time you have Italian night.

Love the “did you know” fun fact? Post it on your Facebook page and tag Keeton’s– we’ll send something awesome to the first 10 people who do it!
