The DataSizer spreadsheet is a tool that helps estimate the size of tables in SQL Server 7.0.

It contains two worksheets, labeled Clustered and Heap. The Clustered sheet gives formulas to estimate the size of a clustered index table and its nonclustered indexes. The Heap sheet gives formulas to estimate the size of a heap table (any table that does not have a clustered index) and the associated nonclustered indexes.

The formulas used in the spreadsheet are exact, but they are not complete (see “Not Covered by the Worksheets” next). Also, the worksheets include detailed information about the space used in each data and index row. You may not need that much detail and can go directly to the Table Size and NC Index Size totals after you have entered the data for your table.
