The restricted area in basketball is a semi-circle arc painted just under the basketball goal that outlines the area on the basketball floor where secondary, off-ball defenders are restricted from taking charges.

The restricted area is a semi-circular arc under the rim. Its primary purpose is to enhance player safety by limiting collisions between offensive and defensive players under the basket. Any secondary defenders who attempt to draw a charge in this area will automatically get called for a blocking foul.

The restricted area, also known as the “no-charge semi-circle”, is a semi-circular zone underneath the basketball hoop. Its purpose is to limit collisions and injuries near the basket, affecting offensive and defensive fouls.

The restricted area is marked on the floor with a two-inch wide half-circle with a radius of four feet from the basket. Although defenders are not allowed to defend from within the restricted area, secondary defenders are permitted to stand, jump, and absorb contact inside the restricted area without incurring a blocking foul.
