MemHandleSize or MemPtrSize.

Fields grow their allocations as text is added. Currently, they grow by 1/5th of the total size or by 16 bytes, whichever is larger, up to the maxChars value set by FldSetMaxChars. You can use FldCompactText to tell a field to trim any unused space out of it's allocation, so that the NULL at the end of the field text is the last byte in the text-related part of the allocation.

Fields are "smart" about growing--you can grow a field that is in the middle of a database record, and the field code will grow the entire record, moving non-field data after the text if necessary.
