Learn why you should resize a PDF and how to do it online, for free.

Converting to PDF will make it easier for you to work with digital content. However, once you have put a lot of effort into creating, formatting, and designing your document, you may also need to prepare it for publishing. In other words, depending on the purposes for which you intend to use the content of your PDF, you may need to resize it first. We are here to show you how to change the PDF page sizes with the help of our easy-to-use Resize PDF online tool. Let’s see why it is important and how it is done!

Why Should I Resize the Pages of a PDF File?

Paper types differ in many parameters. In addition to the method of surface treatment or weight, paper size also plays an important role. The shape and size of the paper cut into sheets are expressed in paper formats. The formats have been standardized over the years, primarily for trouble-free printing.

When it comes to PDF documents, they come in a multitude of page sizes. PDF resizing is one of the commonly used features: There are many situations in which you will be required to change the page size of your PDF document. When it comes to printing the file, changing the page size is often an unavoidable process.

A couple of examples:

  • You may need to print a document on paper other than the standard size you typically use to print MS Word documents.
  • When you need to submit a file for printing, professional publishers will usually be very specific when it comes to the aspect ratio of the PDF file.
  • Single-page PDFs may be too small or too large for your needs, while multipage PDFs may have some pages scaled in different sizes or sizes that are not any standard size at all.
  • In some instances, you may need to resize or scale the PDF to fit for posting (e.g. a web project).

As you will be able to see for yourself from our resizing tool preset – there are many different page size standards. They are being used across different industries for different purposes.

Paper Sizes (Page Size Series) In Short

Both American and European paper sizes include the ISO standards. However, North America, Canada, and parts of Mexico do not use the international standards (they have adopted the ANSI standard). Standard paper sizes like ISO A4 are widely used all over the world. Generally, paper sizes cover:

  • ISO page sizes:
    1. The ISO A series is the most frequently used page measurement standard.
    2. The ISO B sizes are used for poster printing (books, newspapers, magazines, etc.).
    3. The ISO C is meant for envelopes.
  • American paper size dimensions (e.g. ‘Letter’, ‘Legal’, ‘Executive’, ‘Ledger/Tabloid’).
  • English sheet sizes (formats for writing paper and book printing).
  • Newspaper sizes.


PDF is a print-oriented format with a static layout. That is one of the main reasons for its popularity and wide usage. However, if your PDF document is not of an ideal size and should be resized (e.g. the page size is larger or smaller than the paper size), changing the PDF page size is not as convenient. For people who do not want to install any tool on their computer, using an online tool is a good choice.

So, the question is: Do you want to resize your PDFs quickly and efficiently? If the answer is yes – check out PDF2Go's free Resize PDF tool and choose one of many page sizes which are at your disposal! You can easily convert your PDF to any preferable size. The problem will be resolved in a few clicks, indeed!
