title_body: Will Kindle 3 Touch cover case fit a Paperwhite?
upvoted_answer: As far as I know, there is no Kindle 3 Touch. Kindle 3 readers have a keyboard and are therefore larger. Their covers will be too large for a Paperwhite.
  
  If you are talking about a Kindle Touch (4th generation): There are non-original covers that claim to fit for both, so your old cover should fit. On mobileread they do however claim that the Paperwhite is slightly smaller:
  
  
    The PW is 4.6" x 6.7".
    
    The K4 (non-touch) is 4.5" x 6.5".
    
    The K Touch is 4.7" x 6.8".
  
  
  An advantage of buying a new (original) Paperwhite cover is that It has magnets inside. These will automatically switch your Kindle on and off if you open or close the cover.
