A few weeks ago I created a custom, ‘paper size’ to print PDFs of articles on the web. The paper had the dimensions of a mobile screen instead of an A4 sheet.
The results are striking. The same article appears very differently on each paper size. Left is A4, right is my custom size.
Here’s how I calculated the dimensions of the paper in cm based on screen size in pixels.
And here’s how I select the custom paper size when printing
It’s one of those things I should have done years ago.
