Google recently made its search box larger which in turn displays larger text suggestions as searchers type in their queries.
From the Official Google blog:
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.
By enlarging the most important piece of real estate on its homepage, Google has taken one more step toward insuring it remains the preferred search engine of America’s aging population.
