Increase Page Size Using Adobe Acrobat

Adobe Acrobat includes built-in crop and page geometry tools that allow you to expand page dimensions just as easily as you can reduce them.
In Acrobat 10 or newer, select 'Tools' from the top menu, navigate to 'Pages', and click on 'Crop'.
Double-click anywhere on the PDF page to open the Set Page Boxes dialog window.
Locate the 'Change Page Size' section at the bottom of the dialog. Select 'Custom' and enter your new, larger dimensions for the width and height.
Choose whether to apply these new dimensions to a specific page range or 'All Pages', then click 'OK' to add the white space.

Adjust Margins Using Adobe InDesign
If you have the source file, use Adobe InDesign to enable layout adjustment and change margins natively before exporting the PDF.

Frequently Asked Questions
Will adding white space to a PDF distort the original text or images?
No. When you increase the page size or add white margins using a professional PDF editor, the existing content remains untouched. It simply expands the canvas, retaining the original resolution and aspect ratio of your content.
Can I add white space to only one side of the PDF page?
Yes. Most PDF editors allow you to specify custom margins for the top, bottom, left, and right sides individually. In the page settings, you can adjust the offsets to add space exactly where you need it.
How do I ensure the added white space is applied to all pages?
When using the Change Page Size dialog in Adobe Acrobat or similar editing tools, look for the 'Page Range' section. Select 'All Pages' rather than the current page before clicking OK to apply the new dimensions uniformly.
