Inkjet printer paper comes in various weights, typically measured in pounds (lb) or grams per square meter (gsm). The weight of the paper affects its thickness and durability. Lighter paper, around 20 lb or 75 gsm, is suitable for everyday printing tasks. Heavier paper, such as 28 lb or 105 gsm, is ideal for documents that require more durability or a more premium feel, such as presentations or marketing materials.
