Have you ever spent ages crafting a PDF document, agonizing over the text and images to get it ready for printing, only to print it and find that half the content is… missing? A document that you had intended to print on one page has just been printed on four different pages instead?
It could be a scale issue.
It's likely that your content doesn't fit because you've created the document in one size but you're trying to print it in another. Fear not! You don't need to start again from scratch. Simply scale PDF documents using an online tool like UPDF with ready-made document sizes (A4, A3, B4 and more), automatic scaling (scale to fit and shrinking oversized pages), or custom percentage scaling.
Read on to find out more about how to scale a PDF document.

Why You Need to Scale PDF Documents to a Specific Size
There are a number of reasons why you might need to scale or resize your PDF document.
Firstly, you might need to scale a PDF so that the document is ready for printing. If you're printing in a large format, for example a poster, magazine or banner, then you'll need a larger PDF scale. On the other hand, if you're printing small flyers or brochures then you'll need to scale down PDF documents for this purpose. Scaling your document before printing will help to reduce your paper wastage and save you money on printer ink!
You might also need to scale a PDF for its digital purpose. If your PDF is going to be primarily viewed on a mobile phone or tablet, then you might need to scale up so that so that it's easy for readers to view. You might also want to do this to make the document more accessible to those with a vision impairment or disability.
Another reason why you might need to scale PDF documents is when you're integrating your document into another method of presentation, for example a slide show presentation or video. In these cases, it might be helpful to scale up the document to make it easier to integrate.
Lastly, if the content in your document exceeds the paper edges when printing, you'll need to scale down the document to make it all fit on one page. This means you can save money on your printing by not using pages and ink that you don't need.
