I'm not sure what you are looking for. Are you trying to figure the number of bytes returned from a query? Or the number of rows returned from a query?

I quit worrying about sizing of rows and columns a long, long time ago. It used to be that there were complex spreadsheets DBA's would use to determine the row sizes, which in turn helped them determine values for INITIAL and NEXT. But we quit worrying about that a very long time ago. I have not had to size a row or column in forever....

Look at creating a Locally Managed Tablespace. When you create this tablespace, create it using Automatic Storage Space Management (ASSM).

To change the PCTFREE and PCTUSED values, you do that in the STORAGE clause:

CREATE TABLE foo (bar NUMBER)
STORAGE (PCTFREE 1 PCTUSED 9); HTH,
