The power forward (PF), also known as the four, is one of the five traditional positions in a regulation basketball game. Traditionally, power forwards have played a role similar to centers. When on offense, they typically play with their backs towards the basket. When on defense, they typically position themselves under the basket in a zone defense or against the opposing power forward in man-to-man defense.^[4] The power forward position entails a variety of responsibilities, including rebounding, screen setting, rim protecting, and scoring.^[5]

Many power forwards are noted for their mid-range jump-shot, and several players have become very accurate from 12 to 18 feet (3.7 to 5.5 m). Earlier, these skills were more typically exhibited in the European style of play. Some power forwards, known as stretch fours, have since extended their shooting range to three-point field goals.^[6]

In the NBA, power forwards usually range from 6' 8" (2.03 m) to 6' 11" (2.11 m) while in the WNBA, power forwards are usually between 6' 0″ (1.83 m) and 6′ 3″ (1.91 m). Despite the averages, a variety of players fit "tweener" roles which finds them in the small forward or center position depending on matchups and coaching decisions.^[7] Some power forwards, such as Draymond Green and even 6' 5" (1.96 m) P. J. Tucker, have played at the center position, possessing the skills, but lacking the height that is usually associated with the position.^[8]

Power forwards who have been inducted in the Naismith Memorial Basketball Hall of Fame include Vern Mikkelsen, Dirk Nowitzki, Karl Malone, Kevin Garnett, Dolph Schayes, Kevin McHale, Charles Barkley, Dennis Rodman, Elvin Hayes, Bob Pettit, Jerry Lucas, Dave Debusschere, and Tim Duncan.
