This is the logical conclusion of my reset_tempdb and reset_model scripts. It show all of the file sizes and autogrowth settings in the current instance and the code to change them.
The suggested sizes (128 MB for Logfiles and 256 MB for Datafiles) are reasonable for Model, but should probably be amended for other databases dependent on current size and autogrowth history.
--autogrowth_all.sql -- get current settings & create commands to change them select db.Name, case mf.[Type] when 0 then 'DATA' else 'LOG' end [FileType], convert(varchar(50), size*8/1024) + ' MB' [CurrentSize], case mf.is_percent_growth when 1 then convert(varchar(50), growth) + ' %' when 0 then convert(varchar(50), growth*8/1024) + ' MB' end [AutoGrowth], 'ALTER DATABASE [' + db.Name + '] MODIFY FILE (NAME = N''' + mf.Name + ''', SIZE = ' + case mf.[type] when 0 then '256' else '128' end + 'MB);' [ReSizeCommand], 'ALTER DATABASE [' + db.Name + '] MODIFY FILE (NAME = N''' + mf.Name + ''', FILEGROWTH = ' + case mf.[type] when 0 then '256' else '128' end + 'MB);' [AutogrowthCommand] from [master].[sys].[master_files] mf join [master].[sys].[databases] db on mf.database_id = db.database_id order by mf.database_id, mf.[type];
