Rubber Band Size Chart
How to Measure a Rubber Band
Thickness: The band’s thickness helps determine how much stretching and wear it can handle. Thin rubber bands can stretch more but snap more easily, while thicker bands are generally less stretchy but more robust and durable.
Width: This is how wide the cut width of the rubber band strip is, not the length of the rubber band.
Flat length: This is how long the rubber band is when it’s lying flat and straight (not stretched). This measurement is taken by pressing the ends flat and measuring from one end to the other. Flat length is usually about half the total circumference of the rubber band in a relaxed position.
