In basketball, a double-double is a single-game performance in which a player accumulates ten or more in two of the following five statistical categories: points, rebounds, assists, steals, and blocked shots. The most common double-double combinations are points and rebounds for big men and points and assists for guards. Reaching double figures in steals or blocks is extremely rare. When a player reaches double figures in three of the five categories, they have achieved a triple-double. Nearly all triple-doubles consist of points, rebounds, and assists.

For those unfamiliar with basketball terminology, a double-double is a statistical achievement in which a player achieves double digits in two different statistical categories during a single game. Usually, this refers to points and rebounds, or points and assists, though it could also involve blocks or steals. Hitting double digits in one category alone is an impressive feat, but achieving two in a single game is even more noteworthy. One of the most common double-double combinations is points and rebounds. However, steals can also play a crucial role in achieving a double double.

In summary, a double-double in basketball is when a player accumulates ten or more in two of the five statistical categories during a single game. The most common double-double combinations are points and rebounds for big men and points and assists for guards.
