Computing Guide: Resizing Documents for Law School Printers

A guide to computing at Berkeley Law.

Resizing Documents for the Law School Printers

US Letter (8.5" x 11", 215.9 x 279.4 mm, or "ANSI Letter") sized paper is the only paper size available for printing at the Law Library printers.

If your document is formatted for A4-sized paper, our printers should automatically convert it to US Letter, though it may appear slightly differently on the page due to the size differences between the two (A4 paper is taller and narrower than US Letter).

If your document is formatted for any other paper size, such as US Legal, or not consistently sized at all, then Pharos/MobilePrint will not allow you to print the document. You will need to resubmit a properly-sized file to Pharos/MobilePrint in order to print it. You are not charged for these print failures due to paper size.

The MobilePrint website does not perform any resizing, so while you may be able to upload the document, you will not be able to print it out at a release station and will receive an error message when you try. MobilePrint does try to warn you about some file sizes upon upload, but it will not catch everything.

Here are a few options for resizing and printing non-US Letter/A4-sized documents:

  • print from the Computer Lab (using File->Print) instead - the print menu should already have the options selected to scale the pages for you. Don't forget to type in your CalNet username and a name for the document in the Pharos popup!
  • reformat your Word document:
    1. Open and then select your entire document (type Ctrl+A on Windows or Cmd+A on a Mac)
    2. Click on the Layout menu
    3. Select Size -> [US] Letter
    4. Make sure you're still happy with the layout of your document before saving (or saving as a new copy) and uploading to MobilePrint
      • If you are not happy with the changes in the layout, do not save the file. Consider creating a PDF of your original document instead, which can be done through the Print menu (Macs) or the Save As menu (both Macs and Windows). Then follow the instructions below to resize it.
  • resize your PDF and save a new copy:
    • MAC:
      1. Open the file in Preview (if it is not your default PDF viewer, right-click/ctrl+click on the file and choose Open With to select it)
      2. From the File menu, click Print (or type Cmd+P)
      3. Click Show Details if necessary, then ensure the paper size is set to US Letter and one of the Scale To Fit options is selected.
        • While Scale is not the correct option to select, you'll also notice that the scale percentage will probably change to be something other than 100% - this indicates that the file is being resized!
      4. In the bottom left corner of the window, click on the PDF dropdown menu and select Save as PDF (you can either overwrite your current file or save as a new, resized PDF)
      5. Upload the new file to MobilePrint
    • WINDOWS:
      1. Open the file in Adobe Acrobat (NOT Acrobat Reader, which does not have the same functionality). If Acrobat is not your default PDF viewer, right-click on the file and choose Open With to select it.
        • If you do not have Adobe Acrobat, you are entitled to install a free copy while you are enrolled at UC Berkeley. We have more information about installing it here on our Software page.
      2. From the File menu, click Print (or type Ctrl+P)
      3. In the Printer dropdown menu, select Adobe PDF (or other PDF printer option)
      4. In Page Setup... (bottom left), make sure the size is set to [US] Letter
      5. Select the Fit option, then click Print. You will be asked where to save your new (resized) PDF, and the creation process will begin.
        • For long PDFs, this may take some time to complete.
      6. ​Upload the new file to MobilePrint

​​​You can also choose to bring your own paper in other sizes to the computer lab and print on this paper with the help of lab staff - you must provide your own paper to do this.  to do thisdfasfasdfasdfsdfsd
