Was TARP too large or too small ?

It was neither large or small but did its work partially. Troubled Asset Relief Program was to give relief to Troubled assets now if we think of
Troubled Assets = (CDO and toxic assets which banks held + Average American home ).
First goal ( not in that order tough)was to stabilize financial institutions and to get banks lending again and prevent a systemic collapse and it did that. It was always thought of as a temporary thing and folks were supposed to return the money when markets stabilized and it worked.
Second goal was to keep folks in their homes , so far that is clearly not the case , housing market is a clear indication of that goal and its failure to stop the foreclosure crisis calls for some serious contemplation
Verdict : Depending on which goal we value more our verdict on TARP size and goal can go either way
