In today's world, choosing the right fabrics is becoming more and more complicated, especially when we start thinking about the issue of weight. We often hear about this concept, but we don't always realize how crucial it is when buying fabrics, especially cotton fabrics. The grammage is an important factor that affects not only the appearance, but also the durability and comfort of the fabric. Together, let's discover what cotton grammage means and learn how to make an informed choice so that our fabric purchases meet expectations in terms of durability, comfort and aesthetics.


What does the grammage of a fabric mean?


Cotton gram mage is a precise parameter that plays a key role in determining the characteristics of a fabric. Defined as the weight of the fabric per unit area, the grammage is an indicator of the density and thickness of the fabric. In the case of cotton, one of the most popular types of material, it is a particularly important factor affecting its performance and aesthetic properties.

Grammage is usually expressed in grams per square meter (g/m²) or kilograms per square meter (kg/m²). This method of measurement allows an unambiguous assessment of the amount of material in a given area, which in turn makes it possible to compare the grammage of cotton types.


Effect of grammage on density and thickness


The higher the grammage, the thicker and denser the fabric becomes. This means that there are more cotton fibers per unit area, which affects both the feel and durability of the fabric. Thicker and denser fabrics are often more resistant to wear and abrasion, making them an attractive choice especially in the context of products that expect to last, such as bedding and upholstered furniture.


Grammage as an indicator of quality


Cotton gram mage is an important element in assessing the quality of a fabric. A lower grammage may indicate a thinner and more airy fabric, which may be appropriate for summer clothes or delicate accessories. On the other hand, a higher grammage usually suggests a fabric with greater durability, which works well for workwear, curtains or furniture.



How to calculate the fabric weight?


Calculating the weight of a fabric is a relatively simple process that requires only a few steps. The first step is to accurately measure the area and weight of the selected piece of fabric. Then, using a simple mathematical formula, the grammage, that is, the weight of the fabric per unit area, can be calculated. This formula is represented as a quotient of weight to area, which can be written as:

Grammage = weight of material sample (g) / size of material sample (m²)

This process makes it possible not only to obtain the grammage value, but also to make an informed choice of fabrics, tailored to specific needs and expectations. However, it is worth remembering that the precision of measurements and the use of uniform units of measurement are key to obtaining accurate results.


Division of materials based on material grammage


The division of cotton materials based on grammage reflects the diversity of applications and consumer expectations. Here are the types of cotton by grammage:


Low weight (up to 120 gsm)


Low-weight fabrics are light and airy, ideal for summer clothes, underwear, scarves or lightweight decorations. They can also be used in the production of delicate household items.


Medium weight (120-200 gsm)


Medium weight combines lightness with slightly greater durability. It is suitable for everyday clothing, bedding, curtains or lightweight upholstered furniture. They represent a compromise between lightness and durability.


High grammage (above 200 gsm)


High-weight fabrics are thicker, denser and more durable. Used in the production of sturdy work clothes, bags, furniture upholstery, and for projects where durability is important.


Very high grammage (over 300 gsm)


Very high grammage materials are very thick and strong. They are designed for tasks requiring exceptional strength, such as bags for heavy construction materials, specialized protective clothing or industrial equipment items.


Flexible (variable) grammage


Variable weight materials that combine elasticity with different levels of density. They are used in the production of sportswear, stretch clothing, and thermal underwear, where comfort and fit are key.



Printing vs. fabric grammage


In the context of the production of garments and advertising textiles, printing on fabric is an important element that is inextricably linked to the fabric's grammage. In the following description, we will focus on how grammage affects the quality of prints, paying attention to the durability and clarity of graphics or designs.

The weight of the cotton has a significant impact on the durability of the print. At lower weights, where the fabric is thinner, the print may be more susceptible to abrasion, fading from washing and other forms of wear and tear. High fabric weights can offer better protection for the print against abrasion. Thicker and denser fabrics with higher weights can provide a better surface for printing. When this is the case, the print can be more pronounced and more durable, due to the greater amount of fiber available to accept ink or ink.

Different types of cotton offer different grammage ranges, allowing you to match the material to the specific needs of your project. Some methods, such as screen printing, may be more effective on heavier weight fabrics, while others, such as digital printing, may work better on thinner materials. In the production of garments, especially those worn on a daily basis, fabric weight is also important for comfort. Printing on lightweight fabric can be more flexible and airy, which affects the feeling of comfort, while higher-weight fabrics can offer some thermal properties and durability, which is key in more demanding conditions.

We use a wide range of fabric weights in the production of our printed eco bags. In fact, the decision is made by the customer, when placing an order. Our bags are one hundred percent personalized to customers' needs.



The answer to the question of which cotton weight is good for a given project depends on the desired effect - a lower weight can give lightness, while a higher weight guarantees sturdiness and durability. The right choice of cotton weight depends on individual preferences and the application of the material. It is worth understanding that "more" does not always mean "better," and that there is a wide range of weights from which to choose. An informed choice allows you to optimally match the fabric to your specific needs and expectations.
