Rick,

If the CLOB is <4KB and stored inline with the table, then it takes up only as much space as it needs - much like a VarChar2. If the CLOB is stored out-of-line in a LOB segment, it takes at least one, possibly many more, Oracle DB Blocks, depending on your specification of "Chunk" in the Create Table command.
