Does 20 Pound Printer Paper Actually Weigh 20 Pounds?
No, 20-pound printer paper does not weigh exactly 20 pounds. The weight refers to the weight of a ream of paper.
The measurement is based on a standard bundle of paper, typically consisting of 500 sheets. Specifically, 20-pound paper is intended to weigh 20 pounds for that bundle, but each individual sheet may weigh less. Hence, paper weight classification helps determine the thickness and sturdiness of the paper rather than its actual weight when unbundled.
How is the Weight of Paper Measured in the U.S.?
The weight of paper in the U.S. is measured using a unit called “basis weight.” Basis weight refers to the weight of a ream, which is 500 sheets, of paper cut to a standard size. For most types of paper, this standard size is 17 x 22 inches. The weight is given in pounds to indicate the total weight of the ream. For example, 20-pound paper means that a ream of that size weighs 20 pounds. This measurement system applies to different types of paper, such as bond, cover, and writing paper. Each type has its own standard size and weight classifications. Therefore, understanding basis weight helps consumers compare and choose the right paper for various uses.

Why Do Different Types of Paper Have Varied Weights?
Different types of paper have varied weights due to differences in their composition, thickness, and intended use. The weight of paper is primarily determined by the type of fiber used, the density of the paper, and how it is manufactured.
According to the American Forest & Paper Association, paper weight is measured in pounds per ream (500 sheets) of a specific size. For instance, bond paper typically weighs 20lb, while cover paper may be rated at 80lb.
The variation in paper weight arises from several factors:
- Fiber Composition: Different types of trees or recycled material produce fibers that have varying densities. This affects the overall weight.
- Thickness: Thicker paper will naturally weigh more than thinner varieties. Paper thickness is often referred to as “caliper,” which is measured in thousandths of an inch.
- Manufacturing Process: The way paper is made, including the amount of water used and the pressing process, influences its final weight.
- Uses and Applications: Certain papers are designed for specific functions, such as photo printing or legal documents, impacting their weight.
Technical terms like “basis weight” help quantify the weight of paper. Basis weight is the weight in pounds of a ream of paper cut to a standard size. For example, bond paper is measured at 17 inches by 22 inches, while cover paper is 20 inches by 26 inches.
The mechanisms involved in determining paper weight include the raw material’s pulping process and how it is dried. During production, the pulp is formed into sheets, pressed, and dried. The moisture content can affect the final weight.
Conditions that contribute to paper weight variations include the type of machine used in the papermaking process and the desired end use of the paper. For example, photo paper is often heavier due to a higher density and coating to enhance printing quality. Conversely, tissue paper is lightweight for easy packaging and disposal.
In summary, the variations in paper weight stem from fiber type, thickness, manufacturing practices, and specific applications, all of which combine to create the wide range of paper weights available in the market.
How Does Paper Thickness Influence Its Weight?
Paper thickness significantly influences its weight. Thicker paper typically weighs more than thinner paper because weight is determined by both the paper’s density and its size. Density refers to the mass per unit volume of the paper, while size refers to the dimensions of the paper.
To understand this, consider the following steps:
-
Thickness Measurement: Paper thickness is measured in mils or points. One point equals one-thousandth of an inch. Thicker papers will have higher point measurements.
-
Weight Calculation: The weight of paper is often expressed in pounds based on a standard ream (500 sheets) of that paper size. For example, 20-pound paper means a ream of that size weighs 20 pounds.
-
Density Connection: Denser fibers in thicker paper contribute to greater overall weight. As the thickness increases, the amount of fiber material increases, resulting in higher weight.
-
Practical Example: If comparing two papers of the same size, but different thicknesses, the thicker paper will weigh more. For example, a 20-pound bond paper is thicker and heavier than a standard 16-pound bond paper.
In summary, the relationship between paper thickness and weight hinges on density and size. Thick papers contain more material, leading to increased weight.
