A phablet (/ˈfæblət/) is a class of a mobile device designed to combine or straddle the form of a smartphone and a tablet. The word phablet is a portmanteau of the words phone and tablet.Phablets have screens that measure diagonally 5.5–6.99 inches (140–178 mm), a size that complements screen-intensive activity such as mobile web browsing and multimedia viewing. Phablets may also include software optimized for an integral self-storing stylus to facilitate sketching, note-taking and annotation.
