Read below to find out more about the required and recommended upload specifications for your PDF file on Paperturn.
Required Upload Specifications
Must be a .PDF file - any other file formats are not accepted / compatible
The entire PDF file must be a single page spread (If using a PDF file with both single and double-page spreads, your pages may look distorted when converted into a flipbook & linking will not work correctly)
Pages must all have the same width and height
Maximum file size is 512MB. You can have an unlimited number of pages, as long as the file is 512MB or less.
Optimal Upload Specifications
TEXT SIZE: Documents designed for web use should generally have larger text than for print, with the gold standard being viewing your design on an actual device; however, we recommend an absolute minimum font size of 14px (visible only when using the zoom function), with optimal size being 22px for easy reading without using the zoom function.
FORMAT: The dimensions of your flipbook is a matter of personal preference; however, the optimal dimensions for best viewing experience on monitors with standard aspect ratios of 16:9 and 16:10 is 1047px (width) x 1200px (height) (per page). In layman’s terms, a horizontal format page which is longer than it is tall.
