Hello there, I'm a seasoned expert in the field of paper and printing materials. It's a pleasure to share my knowledge with you. When discussing the weight of paper, we're often referring to its thickness and durability, which are crucial factors for various applications, from business correspondence to personal use.

The weight of paper is typically measured in pounds, and this is often abbreviated as "lb." The term "lb" stands for "pound," but in the context of paper, it refers to the weight of 500 sheets (a ream) of paper. The standard weights for paper can vary widely, but as you've mentioned, fine business papers, printer papers, and personal stationery generally range from 20 lb. to 32 lb.

The most common paper weight today is indeed 20 lb. This is a versatile weight that offers a balance between affordability, durability, and a professional appearance. It's suitable for everyday use, including printing documents, letters, and reports. The 20 lb. paper is also known as "standard" or "book" weight, and it's what you'll typically find in office supplies stores.

One important aspect to consider is the relationship between paper weight and its physical properties. As a general rule, the heavier the paper, the thicker and more durable it is. This is important to keep in mind when choosing paper for specific purposes. For instance, heavier paper might be preferred for documents that require frequent handling or for printing high-quality images.

However, it's also worth noting that paper weight is not the only factor that determines the quality or suitability of paper for a particular use. Other factors such as the paper's finish, brightness, opacity, and the presence of any coatings or treatments can also significantly affect its performance.

When selecting paper, it's essential to consider the intended use and the desired outcome. For example, if you're printing a document that needs to convey a sense of professionalism and quality, you might opt for a heavier weight paper. On the other hand, if you're printing a large number of copies for internal use where the paper's weight is less critical, a lighter weight might be more cost-effective.

In conclusion, while 20 lb. is the most common paper weight, the "normal" or "standard" weight can vary depending on the context and specific requirements of the project. It's always a good idea to test different weights and types of paper to see what works best for your needs.
