The Phablet (/ˈfæblᵻt/) is a class of mobile computing devices designed to combine or straddle the size format of smartphones and tablets. The word phablet is a portmanteau of the words phone and tablet. Phablets typically have a diagonal display measurement ranging from 5.5–6.99 inches (140–178 mm) — a range that complements screen-intensive activity such as mobile web browsing and multimedia viewing. They may also include software optimized for an integral self-storing stylus to facilitate sketching, note-taking and annotation. Because of their size, phablet use may require two hands.
