Standard printer paper typically weighs 20 lb (pounds).
This 20 lb designation refers to the weight of a ream (500 sheets) of paper cut to its basic size (17 x 22 inches). It's important to note that this is a basis weight, meaning it's not the actual weight of the 8.5 x 11 inch sheets you use in your printer, but a standardized way to compare different paper stocks.
Here's a breakdown:
- Basis Weight: The weight, in pounds, of a ream (500 sheets) of paper cut to a specific basic size for that grade of paper. For bond paper (like printer paper), the basic size is 17 x 22 inches.
- Common Printer Paper: 20 lb bond paper is the most common weight used in offices for everyday printing and copying.
- Other Weights: While 20 lb is standard, other weights exist. Heavier paper (e.g., 24 lb or 28 lb) is often used for important documents, letterheads, or when a more substantial feel is desired. Lighter weights may exist but are less common for general printing.
Therefore, when referring to "standard" printer paper, the weight is generally understood to be 20 lb (basis weight).
