What’s the difference between GSM and thread count?

On a technical level, GSM refers to the weight of a towel based on how it’s woven. Thread count, however, is the compactness or openness of the weave, according to Arya. “If the weave is compact then the fabric or thread count will be higher, which is an indicator of the durability of the towel,” she says. The two measurements are related in the sense that a higher thread count can lead to a higher GSM, according to Arya.

How to shop for towels using GSM

In general, a high GSM often indicates a towel that is more absorbent and softer than one with a lower GSM. Below, we break down what characteristics you can expect from a towel based on the GSM range it falls in. The GSM of a towel is often listed in the product description. Keep this information in mind when shopping.

300-400 GSM: These are lightweight towels that are usually very thin and not too soft. You’ll also find that low GSM towels do not dry particularly fast and do not hold up as well after washes. That said, these tend to be cheaper than towels with higher GSM.
400-600 GSM: These are towels with a medium weight and level of absorbency, plushness and abrasion resistance. They are generally more expensive than towels with a GSM between 300-400, but typically less expensive than towels with a GSM above 600. This is a good place to start when looking for a high quality towel with a luxurious feel that is also affordable for a range of budgets.
600-900 GSM: These are heavyweight towels that are considered the most luxurious and plush of all the different ranges of GSM in towels. High GSM towels are soft, highly absorbent and typically dry quickly. These types of towels are usually the most expensive variety you’ll find on the market.

Additionally, Arya recommends buying 100% cotton terry towels with a high GSM that are also woven with a loop design and ring-spun yarn. Terry material is generally prized for its high absorbency, according to Arya. “Since the yarns in the uncut pile of the terry towels have low twist and greater surface area, they absorb well,” she says.
