How to change default size when opening an acrobat doculent

[msapromary]

with Win 10, Acrobat 2017, when I open any PDF, it displays a gigantic version of the document.  How can I change the default size from what it is (probably something like fill the screen so that you can't see it all) to something useful, like 75%?

for example:  instead of opening at this 165%, let me change it to 50 or 75%

Go to File - Properties - Initial View and change the Magnification level.

Also, you can check application preference as well goto Edit Menu>Preference> "Page Display."

And try "Zoom"
