Rubber Band Size Chart: Dimensions in Inches and Millimeters

When procuring rubber bands for your business operations, understanding exact dimensions is crucial for selecting the right size for your specific applications. This comprehensive rubber band size chart provides precise measurements in both inches and millimeters for Alliance Rubber Company's most popular sizes, helping procurement professionals make informed purchasing decisions.

Quick Answer

Rubber band dimensions are given as flat length by width. Common Alliance sizes are #19 at 3-1/2 by 1/16 inch (89 by 1.6 mm), #32 at 3 by 1/8 inch (76 by 3.2 mm), #64 at 3-1/2 by 1/4 inch (89 by 6.4 mm), and #84 at 3-1/2 by 1/2 inch (89 by 12.7 mm). Measurements are taken flat and unstretched.

Understanding Rubber Band Size Numbers

Rubber band sizes are designated by numbers that correspond to specific length and width measurements. The size number system was established decades ago and remains the industry standard. Each size number represents the unstretched dimensions of the rubber band when laid flat.

The two key measurements for any rubber band are:

• Length: The distance from end to end when the band is cut and laid flat
• Width: The measurement across the band's width
