Rubber bands have three core measurements that communicate their dimensions: band thickness, width, and flat length.
- 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.
The different sizes of rubber bands convey important details about the circumference of the band, its structural durability, and potential applications. Other factors, such as rubber content, also influence the capabilities of each band and its fitness for certain applications.
This chart describes the approximate number of rubber bands per pound, as well as the attributes of different rubber band types.
|Approx. Rubber Band Count Per Pound|
|Size||Length”||Width”||Pale Crepe Gold®||Sterling®||Advantage®||Pale Crepe Gold|
The rubber band with the softest stretch to help prevent Carpal Tunnel Syndrome and resulting costly insurance claims. It has the highest percentage of rubber content and the greatest number of pieces per pound. Pale Crepe Gold is highly recommended for repeated application.Sterling
The best value per rubber band. It has a high percentage of rubber content and an excellent count per pound. Sterling is highly recommended for fast application and repeat use.Advantage
The rubber band for everyday use. It has a mid-range rubber content. Advantage is recommended for industrial applications where a sturdy band with higher tensile strength is required.

In addition to the length and width measurements, there are other factors to consider when choosing a rubber band.
- Approx. Count Per Pound: The approximate number of natural crepe color bands per pound.
- Ultimate Elongation: Elongation at point of failure.
- Permanent Set: After a rubber band has been stretched, it will typically come to rest at a longer length than before it was stretched. This is expressed as a percent of the original length of the band.
- Specific Gravity: The ratio of the density (weight) of a substance to the density of water.
- Durometer: Measure of the hardness of nonmetallic materials or “resistance to indentation”
At Alliance Rubber, we offer the following three main types of rubber bands.
This is the softest, most pliable band. It’s lightweight and contains the highest amount of rubber compared to the other two bands. Pale Crepe Gold® rubber bands are a popular option for repeated use cases because they are softer and less likely to cause repetitive stress injuries compared to harder rubber bands.
Sterling® rubber bands offer excellent value: they have a high rubber content and a low cost per pound. They’re easier to work with for quick applications and repeated use.
Advantage® rubber bands are slightly harder, stiffer bands with a lower rubber content. Because of their sturdiness, Advantage® rubber bands can be used for industrial and commercial applications that demand stronger, more resilient fasteners.
