GSM stands for grams per square meter and is the most common way to describe how heavy or dense a fabric is. In terry towels, GSM is often used as a quick indicator of pile weight and feel, although construction, yarn type, and finishing also affect how a towel performs.

Ounces per square yard (oz/yd²) expresses the same idea in imperial units. Because buyers in different markets quote weight differently, converting between the two is a routine step when comparing specifications. The GSM to Ounce Calculator handles this conversion directly.

Towel weight and fabric weight are usually estimated from GSM and surface area. Multiply GSM by the area in square meters to get an approximate weight in grams. Finished weights can differ from calculated figures because of pile construction, borders, hems, and finishing.

Fabric consumption estimates how much material a product or order needs. It typically starts with the dimensions of one piece, adds an allowance for wastage or trimming, and multiplies by the order quantity.

Textile measurements and unit conversion come up constantly, with yards and meters for fabric length and inches and centimeters for product size. Converting carefully helps avoid specification mistakes, especially when working with suppliers in different countries.

Basic textile costing combines material cost, production inputs, and quantity to reach a cost per piece or per meter. It is a useful starting point for comparing quotes, though actual pricing depends on many commercial factors.
