Have you ever tried to use the wrong size rubber band only to have it break and snap back on your own hand? If this has happened to you, you understand the importance of choosing the right rubber band size. Too big, and you run the risk of the rubber band not being secure, but too small, and you run the risk of the band breaking and potentially snapping back at you. Continue reading for a rubber band size chart as well as our rubber band buying guide and ideas for rubber band projects.
Rubber Band Sizes and Measurements
Most rubber bands are manufactured out of natural rubber instead of synthetic rubber, as natural rubber has more elasticity. When rubber bands are on the larger side, they are often made from elastomer.
There are a few different measurements to a rubber band, which are then classified with a number. Rubber bands are measured by length, width, and thickness.
For example, size 14 rubber bands are 2 inches long, 1/16 inches wide, and 1/32 thick. The length of a rubber band is defined as half its circumference, the width is the distance from one cut edge to the other, and the thickness is the distance from the inner surface to the outer surface.
The classification of a standard rubber band size goes from smallest to largest, leading with the width measurement. Rubber bands that are 1/16 inches wide are numbered from 8-19. The next step up (numbered 30-35) are rubber bands measuring 1/8 inches wide. This continues for 1/4 inches, 3/8 inches, ½ inches, etc. Longer rubber bands start with a numbered classification above 100.

Colorful Rubber Bands
Colorful rubber bands can be used for creative projects, but they also serve a practical purpose. Colored rubber bands are easier to see if they fall on the floor or ground. In the UK, the postal service is known for using red rubber bands, called Royal Mail rubber bands.
These red rubber bands were implemented in the 2000s after the public complained about the number of rubber bands that were being left in the streets. The idea behind it was that the red bands would be easily noticed by mail carriers if they dropped them by mistake. The switch became a notable campaign and cultural phenomenon.
Projects with Rubber Bands
Rubber Band Ball
A rubber band ball is made by wrapping band after band over an initial ball or knot of rubber bands. The bands are continually added until the ball reaches your desired size.
You can use colored rubber bands to create different styles and patterns around the ball. The largest rubber band ball, which broke the world record, reached 2 meters in diameter. The over 700,000 band ball weighs over 4000 pounds.
Rubber band balls can also be purchased premade in a number of different sizes and colors.
Rubber Band Tie Dye
Rubber bands are the key tool in tie dye projects. Bands are used in different designs to create various patterns on shirts and other items.
The rubber bands hold the shirt in place and ultimately decide where your dye ends up bleeding or not bleeding into the shirt. With rubber bands, you can create as many splashes of color as you want.

Fun Facts About Rubber Bands
- Rubber bands are made by heating a mixture of rubber, sulfur, and other chemicals into strips. The strips are extended into tubes, cured, and then cut into bands.
- The largest consumer of rubber bands is the United States Postal Service. They use rubber bands to organize and sort mail. While the US Postal Service uses the most, the newspaper industry also uses an enormous amount of rubber bands to keep individual newspapers rolled or folded together for home delivery. Florists use a lot of rubber bands to make bouquets, and the agricultural products industry uses rubber bands to bunch vegetables together.
- Rubber bands were first patented in England by London industrialist Stephen Perry on March 7, 1845.
- Ancient civilizations in Mexico and Central America, such as the Aztec, Olmec, and Maya of Mesoamerica, are known to have made rubber using natural latex—a sap-like, milky fluid found in some plants—3000 years before Charles Goodyear received a patent for vulcanized rubber. It is believed they used the rubber to make bouncing balls for use in the legendary Mesoamerican ball games (which often ended in ritual sacrifice.)
