Rubber Band Size Chart
The rubber band is undoubtedly one of the most adaptable pieces of office supplies, with uses ranging from container sealing to keeping documents and other items together to even creating the biggest rubber band ball. The type of resistance band or type of rubber band is very important for band elasticity and band flatness. The advantages of resistance bands are they also have a custom color, have tensile strength, and the manufacturing process guarantees their durability.
Band thickness, width, and flat length are the three primary dimensions that rubber bands communicate.
The thickness of the band influences how much stretching and wear it can withstand. While thicker-colored rubber bands are typically less stretchy but more robust and durable, thinner bands can stretch further but snap more easily.
Width: Not the length of the colored rubber band, but the cut width of the rubber band strip.
Flat length: This is the length of the rubber band when it is flat and straight (not stretched). By flattening the ends flat and measuring from one end to the other, this measurement is taken. A rubber band’s flat length is typically equal to half of its overall circumference when it is relaxed.
There are many rubber product sizes available, and which one you choose will depend on the task you need it to complete. Here is our size chart for elastic bands.

How to choose the right rubber band
Natural rubber, which is more elastic than synthetic rubber, is used to make most rubber bands. When rubber bands are on the bigger side, we frequently used elastomers in their construction.
A rubber product has a few different measurements, each of which is assigned a number. The dimensions of rubber bands are length, width, and thickness.
Rubber bands of size 14 measure 2 inches long, 1/16 inches broad, and 1/32 inches thick, for instance. A rubber band’s width is measured from one cut edge to the other, we measure its thickness from the inner surface to the outer surface, and its length is equal to half of its circumference.
They categorize standard rubber band sizes from least to largest, starting with the width measurement. They print numbers 8 through 19 on 1/16-inch broad rubber bands. Basic Rubber bands that are 1/8 inches wide are the next level up (numbers 30-35). This continues for 1/4, 3/8, 1/2, etc. inches. Longer colorful rubber bands begin with a categorization number higher than 100.

What Other Factors Should I Consider When Buying Rubber Bands?
When selecting a rubber band, there are more aspects to consider besides the length and breadth parameters.
- The Highest Elongation—the rubber band can be stretched before snapping. If the rubber band can stretch to multiples of its original size before the walls thin down, it has a greater ultimate elongation value.
- Permanent Set—When the rubber band is stretched to its maximum elongation and then returned to its natural, un-stretched form, how much longer will it be? A rubber band will stretch to a length that is significantly more than its initial length if the permanent set figure is higher.
- Specific Gravity—a ratio that compares the rubber band’s density to the density of water. A lower specific gravity value can show that the rubber band is of higher quality and contains fewer fillers.
- Durometer—a measurement of a material’s hardness, such as rubber or plastic. The harder and less snap-resistant anything gets, the higher the durometer number is.
How should someone who wants to use rubber bands for simple arts and crafts projects interpret these numbers? They won’t help much—just when you require rubber bands for industrial use. However, if you use rubber bands to bind bulkier objects together, pay attention to the ultimate elongation rating.
Does Rubber Band Size Matter?
The size of a rubber band only matters when you wish to use it to arrange big objects, like using rubber bands to close a laptop or keep books together.
For illustration, contrast rubber bands in Sterling Sizes 117A and 32. Both of them use the same components and have the same proportion of fillers as rubber. They have the same maximum elongation rating of 750%.
According to the sizing table above, a Size 117A rubber band has a maximum stretch of 750% over 7 inches, or up to 52.5 inches, compared to the maximum stretch of merely 22.5 inches for size 32 rubber bands. The largest object that a size 32 rubber band can secure may be a double-coil around a Size 117A rubber band.
But with securing smaller objects, the fewer times you have to loop a rubber band, the easier it will be to unloop from the object later. For this reason, size 32 rubber bands are preferable over Size 117A in these circumstances.
Frequently asked questions
1. What is the standard size for rubber bands?
Rubber bands typically have a standard thickness of 1/32 inches and the standard rubber band sizes, ranging from size 8 to size 107.
2. How large is a size 33 rubber band?
(3-1/2 x 1/8 Inch), 600 Bands/1 lb.
3. How big is a size 64 rubber band?
3-1.2″ x 1/4, 320 Bands/1lb Pack (164).
4. How do I know what size rubber band I need?
When choosing the best rubber band for your project, consider both the rubber content and the cut width, or the band’s width measured perpendicular to its length.
The rubber band is easier to apply and has a softer hold when it is thinner. Rubber bands are more difficult to apply and have a tighter hold when they are wider.
5. How big is a #12 rubber band?
The length measures 38 mm while the width is 1.5 mm
6. How long is a size 54 rubber band?
Size 54 is described as assorted.
7. What is the strongest rubber band?
The alliance rubber band.
Rubber, synthetic rubber, or silicone are the three materials that can make rubber bands. Genuine rubber harvested from rubber trees was used to make rubber bands in the beginning. They make it of a strong, extremely elastic cloth that can stretch up to several times its original size without ripping or breaking.
Non-latex rubber bands, commonly known as synthetic rubber bands, are rubber bands that have latex proteins taken out. A frequent allergy that can cause skin irritation is latex. Synthetic rubber bands are not as strong as natural rubber, despite their ability to stretch and have a respectable snap.
Contrary to its name, silicone rubber bands are completely devoid of rubber. A synthetic compound called silicone mimics rubber’s flexibility. Although it is far more flexible than conventional rubber, it is also much more durable.
