Wire Binding MachinesIf you are shopping for a wire binding machine (found here), you may have come across two or perhaps even three different hole patterns. While wire binding looks great, it can often be difficult to settle on any one wire hole pattern. So which pitch (aka hole pattern) is best? This article will cover all hole patterns and their benefits.

The three hole patterns used in wire binding are referred to as 2:1 pitch, 3:1 pitch and 19-ring. The most common wire binding hole pattern used today is 3:1 pitch. The pitch is the hole pattern, specifically the amount of holes per inch. A 2:1 pitch machine punches two holes per inch and a 3:1 pitch machine punches three holes per inch. A 19-ring hole pattern, often called Spiral-O, consists of 19 total holes along the 11″ side of a sheet of paper.  You can find all our wire binding supplies here.

3:1 Pitch Wire Hole Pattern3:1 Pitch Wire – The 3:1 pitch hole pattern is the most common hole pattern used today for many reasons. To begin with, it has a very tight look because there are three holes per inch of paper. It ends up being about 32 to 33 holes along the 11″ side of a sheet of paper. They can be used to bind up to 9/16″ of paper, which is about 120 sheets. This is very popular for reports and presentations.

2:1 Pitch Wire Hole Pattern2:1 Pitch Wire – The 2:1 pitch isn’t as popular as 3:1, but is very poplar with people that need to bind over 9/16″ of paper. The 2:1 hole pattern can bind documents up to 1 ¼” thick. This style of wire binding machine punches two holes per inch and has a wider look than the 3:1 pitch wire.

19-Ring Spiral-O Wire Hole Pattern19-Ring Wire – The 19-ring Spiral-O pattern was developed to take advantage of existing comb binding machines that used the same hole pattern. The idea was to market a wire supply that could be used with a comb-binding machine. All you would need to purchase would be a separate wire closer to complete the process. A 19-ring pattern looks very similar to a 2:1 pitch pattern. This type of wire binding is not very common.

So what do you do if you like both 2:1 and 3:1 wire bound documents? What you have to do is use a combination binding machine (found here). These are machines that are built with a 2:1 and a 3:1 pitch wire punch. This allows them to punch paper in either hole pattern and is a very useful machine. Our most popular combination wire binding machine is the Akiles DuoMac (found here).

When shopping around for entry-level to mid-level wire binding machines, I recommend keeping an eye open for Intelli-Bind and Akiles. When shopping around for high-volume machines, I recommend Akiles and Renz. You can find our entire selection of wire binding machines here.
