As the definition of GSM above makes clear, GSM is unit of measurement.

In the case of towels, GSM refers to the weight of the fabric per square meter. The higher the GSM, the thicker and more absorbent the towel is likely to be.

Towels with a lower GSM are lighter and thinner, and they may not be as absorbent. These types of towels are typically used for gym or sports purposes, where a lightweight and quick-drying towel is preferred.

On the other hand, towels with a higher GSM are thicker and more luxurious, and they tend to be more absorbent. These types of towels are commonly used in hotels and spas, where guests expect a high level of comfort and luxury.

If you are interested in the technical process of how GSM is measured and why it is a convenient unit for evaluating fabric, refer to this article by Ordnur, which goes over the math involved in calculating the weight of textiles.

GSM is an important factor to consider when selecting towels because it can affect the quality and performance of the towel. Towels with a higher GSM are:

• More absorbent
• Softer
• and more durable

as opposed to their counterparts with low volumes of material per square meter.

A towel with a high GSM can hold more water, which means it can dry you off more effectively. Additionally, a high GSM towel is more likely to retain its shape and color after multiple wash and dry cycles, which means it will last longer and look better over time.

It’s important to note that a higher GSM also means a higher price tag. However, you are paying for quality. High-end bath towels from brands like Abyss and Habidecor, Matouk Linens, Yves Delorme Paris, and Coyuchi have a starting GSM of around 550. As with most things, you get what you pay for.

Different GSMs of Towels have different weights, feels, absorbency, dry times, and uses. Cotton bath towels with at least 400 GSM are good quality which increases as the GSM increases.

As a general rule:

• 300 to 400 GSM towels: Cleaning and gym towels. Lightweight, thin, and rough.
• 400 to 600 GSM towels: Good beach and bath towels. Medium to high weight. Absorbent and soft.
• 700 to 900 GSM towels: Luxury Towels. Heavy weight, extra-plushy, and absorbent.

High quality bath mats and bath rugs typically have a much higher GSM (usually in the range of 900 GSM) because they are thicker than bath towels and bath sheets.

The only con to high GSM towels is that they take longer to dry because they absorb water very well. If you are wondering about how to dry dense towels more quickly, consider investing in a heated towel rack.

As we have gone over, GSM is a testament to the density of towels, and is an important indicator of quality. However, finding the best bath towels is more complicated than just looking at the GSM. Several other factors determine the quality of towels including materials used, production methods, and stlying. We will go over each of these characteristics more in depth below:

• Towel Quality Determinant #1: Materials Used

The quality of materials used in a towel has a huge impact on how durable, absorbent, and soft a towel will be. Opt for towels that use high quality natural fibers, like cotton and bamboo rather than synthetic towels. Egyptian cotton towels and other types of cotton towels are highly absorbent and don't need fabric softener to be the softest around. 

• Towel Quality Determinant #2: Production Methods

Towels that are made with a high-quality weave, attention to detail, and processed without harmful chemicals are more beautiful and last longer. Look for labels like an OEKO-tex certification to ensure that the towel is made in a conscientious and ethical facility.

• Towel Quality Determinant #3: Style

Frankly, some towels are more stylish and beautiful than others. Choose a towel with a style you love as an investment in your quality of life. Beautiful styles from Abyss and Habidecor, Yves Delorme and Matouk towels guarantee quality and style.
