The size of scissors is usually indicated in inches.
The short ones are 4.5 inches, and long ones are up to about 8 inches. Size is selected depending on the cut techniques.
Shorter scissors are more suitable for detailed work, and longer scissors are more suitable for powerful work. Cutting accurately in a straight line is the basic of the blunt cut and, therefore, the 5-inch size is the mainstream. In Asia, where the longer size is more popular, tends to be appreciated due to the greater power and different hair characteristics. The characteristics of long scissors enable efficient work because more hair can be cut at one time, and a higher flexibility can be achieved depending on the method of use.
