can you rotate a comment text box

Too bad! After six years of questions and answers, Adobe has not move a finger better it's software... Like Wesley0101 said : "slapping on a few coats of fresh paint every once and a while to keep up the illusion that its not abandoned-ware...."
I guess we'll have to look eslewhere for working software. 

Yes there is. This is my way (using windows OS):

1. Export the PDF to image

2. Rotate the image using Photos application (built-in on windows OS)

3. Import the image to PDF using DC

4. Paste the comment on DC

Thank me later!

In the free Acrobat Reader DC (Jan 2022), I've found that copying the text contents, and rotating the page (Control Shift Plus) and creating a new comment text box while rotated works. Control Shift minus to bring the page orientation back, providing the desired outcome. You can get this down super fast, especially if your commenting tools are already up on the screen while red-lining a document. Unfortunately, you can't just copy - rotate - paste the box. It'll stay in it's original orientation in that case.

I don't have the pro version so I can't comment on that directly. You also may find different results with different types of text editing. Regardless of all of it, imo the paid version is very expensive, and to not even have an easy rotation tool for the text is exactly the reason why I refuse to support this operation. The free competition is very easy to use, so for the paid version I would expect some incredible tools at the ready. Even a little copy/paste and print-to-pdf is all you need half the time.

FYI.... Rotating the page does not work!

The comment shapes from one document have coded memory or something. This is a majot pain in the butt and something so simple! ADOBE PLEASE FIX

Hi Todd,

Currently, there is no option to rotate comments that you add in the PDF in Acrobat/ Reader.

However, you can use the workaround BerndAlheit mentioned above.

Let us know if you have any questions or need any help.
