David Letterman’s height is 6 feet and 2 inches. The funnyman was born on April 12, 1947 in Indianapolis, Indiana. Prior to going into stand-up comedy, he worked as a weatherman on local Indiana stations. In 1982, he hosted his show Late Night with David Letterman on NBC; however he left the network in 1993 and got another show on CBS called Late Show with David Letterman. The reason behind the move was that David was passed over as host of The Tonight Show, in favor of Jay Leno. Since then the two have been rivals in the late-night wars. In 2009, he married his longtime girlfriend Regina Lasko, the couple has a son Harry, who was born in 2003.
