Pdf pages are too big for KDP book publishing. How do I resize in Acrobat Standard?

[DM Simpson]

I need my pages to be 6.125 x 9.25 inches for uploading to KDP. What app do I use?  I have adobe acrobat standard.  I'm not adept at this program.  I tried different apps but all I found is handles that crop the page.  It also reduces the margins, but nothing to actually set the size to specific measurements. Word programs are so much easier!  Please advise if you know how to do this.

In Acrobat Pro you can do it using the Preflight tool, but that is not available in Acrobat Standard.

To do so in that version you will need to use a script, like these (paid-for) tools I've developed:

Of course, the best way to do it is not in Acrobat at all, but in the original file format used to create the PDF (such as Word). It's important to understand that the PDF format is a final one. You're not supposed to edit the file in such an extensive way once it's a PDF. That's why it's much more difficult to do than in a word-processing application.

In Acrobat you can use print to Adobe PDF.

But don't fix it in Acrobat. Fix it in the app you used to make the book, and just export a new PDF. Like Word, presumably!
