The 2016 Kindle is 11% thinner and 16% lighter than the previous version, making it easier to hold in one hand. It comes with special offers that are displayed on the lockscreen along with the bottom of the home screen and library while not in use. Aside from these advertisements, the Kindle delivers several other useful features that make reading more fulfilling, such as a dictionary – if you don't know a word, just tap on it and a definition will appear. There's also a Time-to-Read function that estimates how much time it will take to finish a chapter or book. Moreover, you can adjust the font size, line spacing, margin, and more to provide a more comfortable reading experience.
