Choose a Coil Pitch

Once you have chosen the length of your coil bind spine, choose your pitch. What is a binding pitch? Pitch refers to the holes per inch, or the hole spacing. They are reflected in a ratio that includes the number of holes:inch...for example, 4:1 means there are 4 holes per inch and 5:1 means there are 5 holes per inch. 4:1 pitch binding coils are by far the most popular, as it is the standard spacing for coils in the US. About 98% of our customers order 4:1 pitch spiral bindings. The 5:1 is a specialty spacing that is manufactured primarily for print shops who have specialty equipment for punching the pattern. You will want to check your spiral binding machine for compatibility.
