4:1 Pitch Coil Bindings

The standard pitch in the United States for the plastic coil is 4:1. Pitch refers to the holes-per-inch or the hole spacing. It is reflected in a ratio that includes the number of holes, a punctuation colon, and then the inch measurement. For example, 4:1. This ratio is read aloud/pronounced as "four to one" and means four holes for every 1 inch of length. 4:1 pitch binding coil spines are by far the most popular, as it is the standard spacing for coils in the United States. About 98% of our customers order 4:1 pitch spiral bindings.

 

Plastic Coil is a great way to add color when binding your book. Measuring at a 12" or 36" length, the pitch for spiral coil bindings can be 4 or 5 holes per inch, with sizes ranging from 6mm (1/4 inch) to 50mm (2 inches). Being both durable and flexible, you'll be able to lay your documents completely flat or wrap around. Our coil supplies keep their shape and come in a variety of colors. If you don't see your color, we will be more than happy to custom PMS match it for you! Get simple, flexible, affordable, and professional spiral coil binding spines right here at SpiralBinding.com.
