The power forward (PF), also known as the four, is one of the five positions in a regulation basketball game. It has also been referred to as the "post" position. Power forwards play a role similar to that of center. They typically play offensively with their backs towards the basket and position themselves defensively under the basket in a zone defense or against the opposing power forward in man-to-man defense. The power forward position entails a variety of responsibilities, one of which is rebounding. 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.
In the NBA, power forwards usually range from 6' 8" (2.03 m) to 7' 0" (2.13 m) while in the WNBA, power forwards are usually between 6' 1" (1.85 m) and 6' 4" (1.93 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. Some power forwards often play the center position and have the skills, but lack the height that is usually associated with that position.
