Required disk space to reindex

Hello,
I would like to know the amount of free space I need to reindex a clustered
index. For a clustered index using 100 GB for example, how much data free
space I need ? (I am not talking about the transactional log) ?
Thanks in advance,
Regards,
VincentVincent
100 GB *2= 200 GB

data) is using 100GB. For that you will need somewhere around 120 GB free space in the database to
rebuild the index. I.e., the size of the index plus some.

To be safe, I would usually ballpark at 1.5x the index size.
