Planner insert sizes: a chart of every refill size

Planner inserts come in a dozen sizes that rarely match a standard paper size. This chart gives each planner insert size in millimeters and inches, the hole or disc spacing, and the printer paper it prints on. Every size is a preset in the Notebook Maker under Planner or binder, with the holes marked on the page.

Measuring your own planner

Makers differ by a millimeter or two, and older covers can be tighter. Measure a page you already own: width and height to the nearest half millimeter, and for ring binders the distance from the top of the page to the first hole centre. In the maker, choose the closest system, then correct the width or height under Page size if needed; the hole pattern stays centred, so a page cut 1 mm shorter still lands on the rings.
