Any tips on creating writable PDFs as downloadable worksheets?
I'm working on Adobe Pro DC and creating documents that can be accessed and written on a smartphone. The font size has to be pretty big to be easily legible, though - 24pt - and (as far as I've been able to work out) can only be written to on a phone if it has the right email client and/or the Adobe app downloaded.
The downside with PDFs is that they are not designed to change size based on the browser (unlike mobile-friendly web pages for example). The only way I can think of to achieve what you want is to create your original file (in Word or whatever software you use) and make the font bigger. You could also change the size of your document to match the common mobile devices formats so that it display nicely. Personally I also find reading PDFs on my cell phone to be a pain and I usually move over to the iPad or the computer.
