Paper weight and thickness.

Paper weight and thickness refer to the measurements of a piece of paper. Paper weight is measured in grams per square meter (gsm) or pounds per ream (lbs), while paper thickness is measured in micrometers (μm) or points. The higher the paper weight, the heavier and thicker the paper will be. Paper thickness can also affect its stiffness and opacity. It is important to consider paper weight and thickness when selecting paper for various applications, such as printing, packaging, and crafting.
