Google increased the size of page contents like text, buttons and other touch targets to give quick access to specific types of results like Images, Videos, Places, and Shopping.
"As part of our effort to evolve the Google design and experience, we"ve improved the www.google.com search experience on tablets. We"ve simplified the layout of search results pages and increased the size of page contents like text, buttons and other touch targets to make it faster and easier to browse and interact with search results in portrait or landscape view," Google said in its blog.
Google said that for image results, they've focused on improvements that enhance the viewing experience such as enlarged image previews, continuous scroll, and faster loading of image thumbnails.
Users can experience the improved layout on iPad and Android 3.1+ tablets in coming days. Stay tuned for more updates.
