Netball The objective of a game is to score more goals than the opposition. Goals are scored when a team member positioned in the attacking shooting circle shoots the ball through the goal ring. The goal rings are 380 millimetres (15 in) in diameter and sit atop 3.05-metre (10.0 ft)-high goal posts that have no backboards. A 4.9-metre (16 ft)-radius semi-circular “shooting circle” is an area at each end of the court. The goal posts are located within the shooting circle. Each team defends one shooting circle and attacks the other. The netball court is 30.5 metres (100 ft) long, 15.25 metres (50.0 ft) wide, and divided lengthwise into thirds. The ball is usually made of leather or rubber, measures 680 to 710 millimetres (27 to 28 in) in circumference, and weighs 397 to 454 grams (14.0 to 16.0 oz). A normal game consists of four 15-minute quarters and can be played outdoors or in a covered stadium.
Each team is allowed seven players on the court. Each player is assigned a specific position, which limits their movement to a certain area of the court. A “bib” worn by each player contains a two letter abbreviation of indicating this position. Only two positions are permitted in the attacking shooting circle, and can therefore shoot for a goal. Similarly, only two positions are permitted in the defensive shooting circle; they try to prevent the opposition from shooting goals. Other players are restricted to two thirds of the court, with the exception of the Centre, who may move anywhere on the court except for a shooting circle.
