For our coil bound planners, you are able to add up to 4 add-ons. However, if you’re choosing a length of 18 months with a weekly inside page layout, you will only be able to add up to 3 add-ons. This is for the sake of binding. 18 month planners get pretty thick, and adding that extra paper pushes the boundaries. A lot of testing has told us that we can do 3 add-ons with that size. Be wary, the 18 month planners are behemoths. They’re great, don’t get me wrong, but heavy, especially in hard cover form. We use some of the best paper in the business of planners, so that paper weight really adds up.
For our sewn bound planners, you are able to add up to 2 or 4 add-ons, as the number of add-ons would have to be even due to the way our sewn bound planners are created to fit within their spines.
