What is Paper Grammage?
Paper grammage, also known as basis weight, refers to the weight of paper per unit area. It is expressed in grams per square meter (GSM) or pounds per ream (a ream is typically 500 sheets). When you hold a sheet of paper, its grammage determines its density and thickness. Just like how different fabrics have different weights and textures, papers with varying grammages possess unique characteristics.
At MailerBoxFactory, we specialize in producing high-quality packaging solutions using various paper grammages. Our website, mailerboxfactory.com, showcases our wide range of customizable boxes, mailers, and packaging materials.
How is Paper Grammage Measured?
Measuring paper grammage is a precise and crucial process that involves specialized equipment and techniques. Manufacturers employ sophisticated instruments to ensure accurate measurements and consistency in the production of paper.
The measurement process begins by obtaining a representative sample of the paper. This sample is carefully cut to a specific size, ensuring it covers a known area. Next, the sample is placed on a highly sensitive balance, capable of measuring even the slightest weight differences.
Once the sample is in place, the balance records the weight accurately. This weight is then divided by the area covered by the sample, resulting in the grammage value. For example, if the sample covers one square meter, the recorded weight represents the grammage in grams per square meter (GSM). Similarly, if the sample covers one square foot, the grammage is measured in pounds per ream (500 sheets).
To ensure precision, manufacturers often take multiple samples from different areas of the paper reel or stack. These samples are then averaged to obtain a reliable and representative grammage measurement.
The measured grammage value provides essential information about the density and weight of the paper. This information is vital for various applications, such as printing, packaging, and determining the appropriate paper for specific uses.

What is PT?
PT, or paper thickness, is a critical parameter in the world of paper manufacturing and usage. It refers to the physical thickness of a single sheet of paper and plays a significant role in determining the tactile and visual characteristics of the paper.
Measuring paper thickness requires precision instruments known as micrometers. These devices are designed to provide accurate measurements in micrometers (µm) or thousandths of an inch (mil). The micrometer consists of a movable spindle and an anvil, between which the paper is placed for measurement.
To measure the thickness of a sheet of paper, it is carefully positioned between the spindle and the anvil, ensuring that the pressure applied is consistent. The micrometer is then gently closed, and the reading on the device’s scale indicates the thickness of the paper.
Paper thickness is an essential factor to consider in various industries and applications. For example, in the printing industry, the thickness of the paper affects the quality and durability of printed materials. Thicker paper can withstand more handling and provides a substantial feel, making it suitable for business cards, invitations, and high-end brochures.

Understanding Thickness
When we talk about the thickness of paper, we are referring to the physical measurement that determines how thick or thin a sheet of paper is. Paper thickness is an essential characteristic that influences its durability, functionality, and overall quality.
To understand thickness more comprehensively, let’s explore the various aspects that contribute to this parameter.
- Fiber Composition: The type of fibers used in the papermaking process affects its thickness. For example, papers made from long fibers tend to be thicker than those made from shorter fibers. Additionally, the presence of additives, such as fillers or coatings, can also impact the thickness of the paper.
- Manufacturing Process: The way paper is manufactured plays a crucial role in determining its thickness. During the papermaking process, the pulp is spread onto a mesh screen and compressed to remove excess water. The pressure applied during this step affects the density and thickness of the resulting paper.
- Calendering: Calendering is an additional step that some papers undergo to enhance their smoothness and finish. This process involves passing the paper through a series of rollers that apply pressure and heat. Calendering can influence the thickness of the paper by compacting its fibers and reducing its thickness slightly.
- Weight and Density: The weight and density of the paper are closely related to its thickness. Heavier papers with higher grammage tend to be thicker, while lighter papers with lower grammage are thinner. This relationship between weight and thickness is an important consideration when selecting paper for specific applications.
Understanding the thickness of paper is vital for making informed decisions in various industries. For instance, in the printing industry, the thickness of paper affects the overall appearance and feel of printed materials. Thicker paper lends a sense of quality and durability to items like business cards, brochures, and packaging inserts.

How Does Grammage Relate to PT and Thickness?
Understanding the relationship between paper grammage, PT (paper thickness), and overall thickness is essential for choosing the right paper for specific applications. Let’s delve deeper into how these factors are interconnected.
Grammage, as mentioned earlier, refers to the weight of paper per unit area, usually measured in grams per square meter (GSM) or pounds per ream. It provides information about the density and weight of the paper.
When we consider grammage in relation to PT and overall thickness, we find that there is a direct correlation between these parameters. Higher grammage indicates a denser paper with more fibers packed into each square meter. This increased fiber density results in a thicker sheet of paper. Conversely, lower grammage signifies a less dense paper with fewer fibers, leading to a thinner sheet.
To better understand this relationship, let’s imagine two sheets of paper, one with a higher grammage and the other with a lower grammage, but both having the same physical dimensions. When we hold these sheets, we can feel that the one with higher grammage is thicker, while the one with lower grammage is thinner. This is because the higher grammage paper contains more fibers per unit area, giving it a greater overall thickness.
It’s important to note that the relationship between grammage, PT, and overall thickness is not linear. For example, doubling the grammage doesn’t necessarily double the thickness. The density and arrangement of fibers, as well as the manufacturing process and paper composition, contribute to the complex relationship between these parameters.
Understanding this relationship is crucial when selecting paper for different purposes. For applications that require sturdiness, such as packaging materials or business cards, higher grammage paper with greater thickness and PT is often preferred. On the other hand, for applications like writing or internal documentation, where weight and thickness are less critical, lower grammage paper may suffice.
At MailerBoxFactory, we offer a wide range of packaging solutions using papers with varying grammages to meet diverse customer needs. Our expertise allows us to recommend the most suitable grammage and thickness for your specific requirements, ensuring optimal performance and aesthetics.
