What is the Series of a Staple?

Why do staples have different series and what do they mean?

In short, there is no meaning to the number that they are given. Companies create these numbers as a reference to the type of staple that they supply. For example, the 80 series is larger than the 71 series, and the 140 series is larger than both of those. However, the 50 series staple is roughly the same gauge as the 140 series, but they vary in crown sizes.

The Crown is the 'bridge' that connects the two legs of a staple together.

See the chart below for the variations of staples sizes.

Note: Finishes of staples have varying available leg lengths.
