title_body: Calibre to Kindle Book Transfer I just bought a Kindle Paperwhite. I am having troubles transferring books from calibre to Kindle. The major problems that I face are as follows:
  
  
  Font size even after changing the PDF format to either MOBI or AZW3 format remains so small that I am not able to read the book.
  Whenever I transfer books from Calibre to Kindle, the dictionary disappears every time. I have downloaded the dictionary five times so far.
  
  
  Could somebody help me with that?
upvoted_answer: Increasing font size and spacing is a frequent problem for PDFs, especially for tablets that are 6 inch. PDFs are supposed to be printable documents, and so font size and other things tend to be fixed proportionate to the document size. 
  
  Merely converting to .mobi will not solve this. 
  
  If your original book were .epub, this is less likely to be a problem because it is based on HTML which is reflowable. 
  
  My recommendation is to try to read the PDF on a mobile PDF app instead of doing another conversion. Also, the larger the tablet size, the easier the PDF will be to read anyway. I have a 9 inch device where PDFs are generally easy to read. 
  
  Another idea (if you are desperate) is to try to copy the text in the PDF to a MS Word file, and then do the conversion from MS Word. Those kinds of conversions tend to produce significantly better results in Calibre.
