There’s no simple way in SQL Server to see the sizes of all the tables and their indexes. Even seeing a single table’s size through SSMS can take a while. The solution below is grabbed from statistics, so there’s no guarantee you’re getting exact numbers. However, exact numbers don’t tend to matter, as you care more that the table is about 1 GB, not that it’s exactly 998 MB.
There are variations of this code floating all over the place, and I tweaked the results to be in the easiest to read format possible.
The only issue I have with this script is that you have to scroll to the next-to-the-last line to filter which tables it’s pulling. Yes, I’m picky, and I don’t like to scroll to see things that change.
