The Acrobat X Standard do have the options for the crop pages.
Please try a different file and check whether it is enabled. If you still have the issue, try repairing the Acrobat.
I have tried Multiple PDFs. Nearly 100 of them. Some that were even already cropped. The PDFs that I have created directly using this version of Acrobat all behave the same way. The ONLY way to crop a PDF is to use the goofy and inaccurate "draw a box and double click" method.
I have "Repaired" the installation of the program, I have uninstalled, wiped the registry in Win7 of all things Adobe (reinstalled flash and other browser plugins) and reinstalled the Acrobat X, and it still behaves this way.
I very much like the headers and footers features. But if the Crop tool will not work as designed, I am going to very much hate this program all around.
I have another problem that keeps displaying my created PDFs that have white area with a grey and white checkerboard, but thats another thread for now.
Please provide a more advanced answer than the basic "here's how its supposed to work - RTFM" response.
I am also frustrated by the same problem. I am running a fresh install of Windows7 and Acrobat X Standard. My HP Officejet Pro L7680 has a legal size scanner that I use extensively. Previously with Acrobat 8 Standard I had no problem using the crop tool as needed to resize an entire document from legal size to letter size. I paid for the Acrobat X Standard upgrade assuming this function would still be there. But the option to crop to a specific size is greyed out. Is this a bug will be fixed at some point, or has this function been permanently withdrawn from Acrobat X Standard? Please let us know.
I have received no new information from anyone yet. No updates have been made for this product and nowhere else on the internet does any useful info exist. This is chock full of suck too because I have presets for different printers for which the tool is useful and I cannot use it. I have to estimate carefully and Im getting better but its stoooooopid.
If you are stuck with this problem, try PDFill PDF Tools 8.0. It can be downloaded for free from www.download.com. It includes a simple utility that can crop all the pages in a document to a specific size. It is working well for me. I still can't believe that Adobe would fail to include this function in Acrobat Standard. It doesn't make sense!
