Firstly, what is GSM? GSM stands for grams per square meter. In the textile industry, this number is used to measure the density of a fabric. A fabric’s GSM varies by 3%. Hence, a material of 300 GSM can range from 291 to 309 GSM. The gsm of a fabric can be measured using a weighing scale or balance. However, it is possible to perform an analysis of fabric by yourself by applying a simple formula.
The full form of GSM is grams per square meter. The measurement is useful when choosing the right fabric. In terms of thickness, the higher the gsm, the thicker the fabric. A cotton T-shirt with a GSM of 90g/m2 will be thicker than a rayon shirt. Conversely, a rayon-based shirt with a GSM of 100g/m2 will be thin and lightweight.
Another common mistake people make is assuming that GSM and thread count are the same. Neither of these measurements is accurate. Thread count refers to the number of threads per square inch. A 160gsm fabric, on the other hand, requires two meters. Increased GSM is not as useful as the higher thread count. In fact, GSM and thread count are not comparable. The higher the GSM, the more expensive the fabric.
A higher GSM number indicates a more durable fabric. For example, a linen shirt with a GSM of 180-200 would be thick and heavy, while a cotton shirt with a GSM of 100-110 will be light and airy. Similarly, a cotton shirt with a GSM of 100-110 is made for promotional purposes. This type of T-shirt is not suitable for the winter as it is prone to fading.
The fabric weight is a key determining factor in quality. A good T-shirt has a minimum GSM of 180 and a maximum of 200 GSM. GSM does not determine the quality of a T-shirt; it also depends on the type of cotton, the mix, the knit, and the season. Combed cotton is a popular fabric used in t-shirts, and is the most durable.
GSM stands for grams per square meter. It refers to how much fabric one square meter weighs. It is used by manufacturers as a quality control tool and helps consumers determine which weight is best for their needs. Further, it tells consumers how heavy a fabric is compared to another of the same weight. This can be useful when buying hoodies. Similarly, hoodies that have higher GSM use thicker fleece and will keep you warm.
T-shirt fabric weight is also an important factor. Fabrics of this weight are often more expensive than lighter weight ones. So, it is crucial to choose the right fabric based on the intended use of the garment. For example, a heavyweight cotton may range from 300 to 900 GSM. Moreover, the GSM will help you select the best product for your needs. If you are buying T-shirts for your children, you may want to select lightweight ones.
