In Europe textile engineers often use the unit tex, which is the weight in grams of a kilometre of yarn, or decitex, which is a finer measurement corresponding to the weight in grams of 10 km of yarn. Many other units have been used over time by different industries.
Some yarn retail stores try to help the customer choose yarn by attaching a sample knitted square to the shelf holding each display of a particular weight of yarn, sometimes provided by the manufacturer. These samples are knit in the industry standard four-by-four inch / ten-by-ten centimetre gauge. Samples help the buyer by showing them the texture and thickness of the finished knit fabric.
