Screen size is important

Jakob Nielsen has something new to say about mobile devices. He’s written in the past on the problems of reading on mobile devices, and in today’s newsletter he expands on new research.

His article is worth reading in entirety, so I’ll just summarize it here.

Someone did a study that compared how well participants understood the privacy policies of 10 popular websites: eBay, Facebook, Google, Microsoft, Myspace, Orkut, Wikipedia, WindowsLive, Yahoo!, and YouTube. The testees were split between a group that read on a desktop size screen and a group that read on an iPhone size screen. The 2 groups were tested to see how well they comprehended the privacy policies. The second group did significantly worse.

  • Desktop screen: 39.18% comprehension score
  • Mobile screen: 18.93% comprehension score
