Internal length

This field type is the length of the field when it is stored in a file. This is the number of bytes used to store a field in a file. Fields with decimal positions are entered as total number of digits, number of decimal places. For example, for a field to contain 999.99, the length would be 5.2.

See the chapter "Maintaining Your Data Model" for more information on defining a field type with differing lengths between external and internal fields.
