Is it possible to get a good estimate on how much space a feature class will take once loaded into ArcSDE from how big they are in a FGDB? I have some feature classes in a FGDB, where some are a few GB's.
I'm using Oracle/ ArcSDE 9.2

you can get the same information here - How to get the size of a file geodatabase feature class on disk?
enable the Size column in the Customize menu -> ArcCatalog Options -> Contents tab
i hope it helps you...

On disk is fine, as that is what I'm doing at the moment, I want to find out whether from the file sizes in the FGDB I can estimate the size before I load it into ArcSDE.– MapManCommented Jun 7, 2012 at 8:25

3Estimate, sure. It will generally be larger on SDE because there are more metadata tables and different storage types may be less efficient space wise. Why not do a test? Put up a small feature class and ask your DBAs to figure out its size (hopefully they will know how, it's not a simple matter). Compare the two and extrapolate from the difference for your real feature classes.– blah238Commented Jun 9, 2012 at 3:10
for ArcSDE run the script below in MSSQL Manager Studio. Then save it as csv, open in excel and sort / sum ...
SELECT
t.NAME AS TableName,
p.rows AS RowCounts,
SUM(a.total_pages) * 8 AS TotalSpaceKB,
SUM(a.used_pages) * 8 AS UsedSpaceKB,
(SUM(a.total_pages) - SUM(a.used_pages)) * 8 AS UnusedSpaceKB
FROM
sys.tables t
INNER JOIN
sys.indexes i ON t.OBJECT_ID = i.object_id
INNER JOIN
sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
INNER JOIN
sys.allocation_units a ON p.partition_id = a.container_id
WHERE
t.NAME NOT LIKE 'dt%'
AND t.is_ms_shipped = 0
AND i.OBJECT_ID > 255
GROUP BY
t.Name, p.Rows
ORDER BY
t.Name
