In this general setting, it is possible to set a limit on how many characters both Style Name and Itemsize name can have.
You can use this if you need to make sure that users don't make too long names on Styles or the Itemsiezes.
Just type in the number you need.
Remember that spaces will count as a character.
Once such a limitation is set - the user will not be able to save Styles with a style name that is longer or save ItemSizes with a name that is longer than the given limit.
