Rubber band sizes guide & chart
Last Updated on 06/10/2025
Rubber bands are one of the most versatile items of office stationery, used worldwide for everything from bundling documents to sealing containers. But with so many different rubber band sizes, finding the right one can be tricky. This guide and rubber band size chart will help you choose the perfect elastic band for your needs — whether for office, home, or school use.
What is the standard rubber band size?
There isn’t a single “standard” rubber band size. Instead, sizes are defined by their length (mm) and width (mm). For example, a Size 34 rubber band measures 101.6mm long by 3.2mm wide. This size system makes it easier to identify which band is best for your task.

Practical uses of rubber band sizes
Different rubber band sizes suit different applications. As a general rule:
-
Thin, smaller bands (sizes 10–34) → ideal for light office tasks such as bundling envelopes, grouping pens, or keeping small items together.
-
Medium bands (sizes 36–64) → perfect for everyday packaging, holding notebooks closed, or sealing food containers.
-
Thicker, heavy-duty bands (sizes 75–90) → designed for more demanding tasks like keeping shoeboxes secure, holding files, or bundling larger items.
For flexibility, many offices prefer buying rubber band multipacks, which cover a wide range of everyday needs. As one of the most useful office essentials, rubber bands are indispensable for daily tasks at work or at home.
