When you buy custom notebooks and planners in bulk, understanding paper weight isn’t just a technicality—it impacts the look, feel and durability of your product. In most of the world paper is described in grams per square metre (GSM), while in North America it’s common to see pounds (LB or #). There are also points (PT) to express thickness and millimetres (MM) for precision measurements.
