When it comes to paper, weight refers to the thickness and stiffness of the sheet. Paper weight is typically measured in grams per square meter (gsm) or pounds (lb), and it can greatly affect the appearance, durability, and uses of the paper. Here are the different weights of paper commonly found:
Lightweight Paper: - Weight: 35-55 gsm (20-32 lb) - Description: Lightweight paper is thin and flexible, commonly used for items like newspapers, book pages, and flyers. It is easily folded and suitable for projects that require frequent or large-scale printing.
Standard or Copy Paper: - Weight: 70-90 gsm (20-24 lb) - Description: Standard paper is the most commonly used for printing and photocopying, found in offices and homes. It strikes a balance between weight, cost, and quality. It is suitable for documents, letters, and everyday printing needs.
Cardstock or Cover Paper: - Weight: 130-350 gsm (80-130 lb) - Description: Cardstock is a heavier-weight paper known for its sturdiness and durability.

It comes in different weights, with heavier options needed for more extensive or water-intensive techniques. The weight determines how much water the paper can absorb without warping or buckling.
