Why do they call it 20lb paper? The term "20lb paper" refers to the weight of a ream of paper, which is 500 sheets, in its uncut size before being trimmed to the standard dimensions used in offices. This measurement helps differentiate paper types based on thickness and sturdiness, making it easier to choose the right paper for specific needs.
What Does 20lb Paper Mean?
The 20lb paper designation is part of the paper weight classification system used in the United States. This system measures the weight of a ream of paper (500 sheets) before it is cut to its final size. For example, a ream of 20lb bond paper weighs 20 pounds when in its uncut size, typically 17 x 22 inches. When cut to the standard letter size of 8.5 x 11 inches, the weight per sheet is reduced, but the designation remains.
Why Is Paper Weight Important?
Understanding paper weight is crucial for several reasons:
- Printer Compatibility: Certain printers handle specific paper weights better. Using the wrong weight can lead to jams or poor-quality prints.
- Appearance and Feel: Heavier paper often feels more substantial and professional, making it ideal for presentations or formal documents.
- Durability: Heavier paper is generally more durable and less likely to tear, which is important for documents that need to last.
How Is Paper Weight Measured?
Paper weight is measured in pounds (lbs) using the basis weight system in the U.S. This system can be confusing because it depends on the type of paper and its original size. Here’s a breakdown:
- Bond Paper: Commonly used for office paper, measured at 17 x 22 inches.
- Text Paper: Used for book printing, measured at 25 x 38 inches.
- Cover Paper: Used for covers, measured at 20 x 26 inches.
The weight designation (e.g., 20lb, 24lb) is based on the ream’s weight in its uncut size.

What Is the Difference Between 20lb and 24lb Paper?
The main difference lies in thickness and weight. 24lb paper is thicker and heavier, providing a more premium feel, which is ideal for formal documents and presentations. In contrast, 20lb paper is lighter and more suitable for everyday printing tasks.
Can I Use 20lb Paper in a Laser Printer?
Yes, 20lb paper is compatible with most laser printers. However, for high-quality prints, such as those needed for presentations, a heavier paper like 24lb or 28lb might be preferable.
Is 20lb Paper Suitable for Double-Sided Printing?
While 20lb paper can be used for double-sided printing, it may not prevent ink from showing through to the other side. For better results, consider using 24lb or heavier paper, which is less likely to have this issue.
Why Is Paper Weight Measured in Pounds?
The use of pounds for measuring paper weight is a traditional system that reflects the weight of a ream in its uncut size. This system helps maintain consistency across different types of paper and their intended uses.
How Do I Choose the Right Paper Weight?
Choosing the right paper weight depends on your specific needs. For everyday tasks, 20lb paper is sufficient. For more formal documents, consider using heavier paper like 24lb or 28lb to ensure a professional appearance.
