Google decided to supersize the search box on homepage and on search results pages "The new, larger Google search box features larger text when you type so you can see your query more clearly. It also uses a larger text size for the suggestions below the search box, making it easier to select one of the possible refinements. (...) Google has always been first and foremost about search, and we're committed to building and powering the best search on the web — now available through a supersized search box," explained Marissa Mayer.
