Understanding paper weights can be challenging due to the diverse range of paper stocks available. This guide will clarify different paper weights, their applications, and how to choose the best one for your notebooks. At Interwell, we're here to help you find the perfect notebook paper weight and answer any related questions.
In the paper business, standard methods are used to quantify stock. Here we introduce the concepts of pounds (sometimes written as "#" or "lb"), points (often written as "pt"), and GSM.
Lightweight papers, while versatile, face challenges, especially in opacity. High-opacity papers allow minimal light passage, preventing print bleed-through.
Medium weight papers, such as cover stock sheets and card stocks, typically range from 65 to 80 pounds (or 170 to 216 gsm).
Card stocks in this category are much thicker than those in the medium-weight group. Their weight is best compared to a greeting card. Weights for heavy paper range from 80 to 200 pounds.
Lastly, card stocks weighing 111 pounds or more fall under the Extra Heavy Weight category; this is almost the same weight as a cereal box but isn't quite as stiff. Again, test printing is required on these paperboards. Some of the papers in this group are double thick, making them as substantial and sturdy as a sheet of chipboard.
