Plastic Coil Binding FAQs
What coil bind pitch do I need?
The most common binding pitch for Plastic Coils (by far) is the 4:1 pitch, but some industry-specific customers use a 5:1. As you get into bigger sizes, you might want to switch to a 3:1 so it makes inserting the coils easier (call for more details).
What is the largest book a coil can bind?
If you're talking about sheet size, then the limit of size will depend on your machine. Plastic Coil is stocked in a 36" length (in addition to the standard 12" length), so you can bind a book up to 35" long.
If you're talking about book thickness, then the answer is about 375 sheets or 750 pages (20 lb. bond copy paper) using the largest coil available, a 50mm.
Why is the coil longer than my book?
Plastic Coils are 1" longer than the intended binding edge length to allow for cutting and crimping-in each end. This leaves 1/2" on each side of your page; smaller extensions can be more difficult to handle. For example, standard coils are 12" long and intended for a letter-size paper that is 11" long.
How do I know what coil size I should get?
The most accurate way to determine the best coil size for your book is to lay all your pages on a desk (including covers and any inserts) and measure the stack's thickness, then add 1/8" to that. Ensure you are not pressing your pages down when you measure them; allow them to lay loose. If you press down, you may end up with a coil size that is too small to allow your pages to turn freely.
Another way to determine the best size is by sheet count. Bear in mind; however, that sheet count is determined using all 20 lb. bond copy paper, so if you are using thicker stock, have covers, tabs, or anything else, this may not be accurate.

Is the coil size the outside or inside diameter?
Coil binder measurements are the inside diameter, or "ID."
Can I buy smaller packs?
Our coils are pre-packaged in packs of 100 or 50, depending on the size. We cannot break down packs to offer smaller quantities.
Can I buy assorted packs?
Currently, we do not offer assorted colour or assorted size packs.
Is coil binding better or worse than wire and comb?
All binding methods have their pros and cons. Coil, however, is consistently wonderful- which is why it is our best-selling binding supply. It is flexible, editable, allows books to open flat and rotate 360 degrees. But a lot of times it is user preference that plays the biggest factor in what binding method to use.
What colours are available?
We stock 8 colours of Plastic Coil (Black, Blue, Clear, Forest Green, Navy, Red, Reflex Blue and White), but there are over 50 colours available to choose from that we produce in our Manufacturing plant in Toronto. You can check out the colour variations by ordering a free colour chart.
Is it possible to coil bind without a machine?
Having a Plastic Coil binding machine will give you the most variety of binding, as you will be able to punch any paper stock you want. It is possible to insert coil binding without a machine, but it takes a long time and you will still need the proper crimpers to make sure the coils do not fall off your book.
How much do Plastic Coil Binding Machines cost?
