finding the actual size of a download for us folk the have a limited amount of data

   I would like to know how to find the size of a download?  And if I really need it for my security and to see if I want to take that risk.  It is a I need to know and it should be post under the download itself, not just a button that says install now with no other information shown?????    Why you ask?  Again!  it's ON a need to know basis what the download size is, for us folk that have a limited amount of data!  Size matters. Numbers are nice too!   So, if you would please help me out here.
