> ## Maximum number of bytes required by fields of type CHAR and VARCHAR

> In OpenEdge SQL, when you create a field of type `CHAR` or `VARCHAR`, the maximum number of bytes required depends on whether the code page is single-byte, double-byte, or triple-byte. For example, a `CHAR(4)` field requires a maximum of 4 bytes if the code page is single byte, a maximum of 8 bytes if the code page is double-byte, and a maximum of 12 bytes if the code page is triple-byte.

> Note: If you define a field as `CHAR(10000)` and the code page is UTF-8, which is a triple byte, the field requires a maximum of 30,000 bytes of storage.
