You need to have an eye on the following:

1. No. of columns included along with datatype of those columns since that would take more size
2. Fill Factor needs to be carefully analyzed for future growth of the table and index.
3. Check whether the index is actually required on the table.
4. Huge No. of indexes on a large table would increase the time taken to insert records into the table as well as update records or delete records.
