Choose a Coil Size / Diameter

Now choose your coil diameter for your page capacity. You can use the capacity chart here to help choose the best size based on your stack thickness or an estimate of your sheet capacity. Finding how to choose the best coil size is easier than you may think with our capacity chart. There is also a general rule with 3 simple steps to get the proper fit for any kind of binding that works as well: ① Take the book being bound and lay it flat on a table. ② Don't compress the paper and measure the thickness of the binding edge. ③ Take the measurement and add 1/8" - that will be the size of the binding element recommended for your document thickness.

* You will also see that we offer a "sheet capacity" rating above. Using this method of size selection may be less accurate, as it was calculated using all 20 lb. bond paper, with no covers and no other paper stocks. The actual sheet capacity will vary depending on what paper stock and covers you are using. For this reason, we recommend you use the stack capacity for a more accurate fit. All of these capacities are approximations.
