Double-Double and Triple-Double in Basketball, Explained

Watch a broadcast late in a close game and you will hear the announcers start counting: “He needs two more rebounds for the triple-double.” A player suddenly starts crashing the glass or hunting one last assist. The chase is real, and it is one of the few individual milestones basketball tracks live, in front of everyone.

What the terms mean

Basketball keeps five main counting stats in the box score: points, rebounds, assists, steals, and blocks. A double-double means a player hit double digits (10 or more) in two of those five in a single game. A triple-double means double digits in three.

The word “double” refers to a two-digit number, not to doing something twice. So 12 points and 10 assists is a double-double. Add 11 rebounds and it becomes a triple-double.

Most triple-doubles come from the same three categories: points, rebounds, and assists. That combination rewards a player who scores, controls the boards, and sets up teammates. Steals and blocks reach double digits far less often, so triple-doubles built on defense are rare.

How the counting works

Stat line	Result
22 points, 11 rebounds	Double-double
10 points, 14 assists	Double-double
18 points, 10 rebounds, 12 assists	Triple-double
30 points, 10 rebounds, 10 assists, 10 steals	Quadruple-double
9 points, 15 rebounds, 15 assists	Not a double-double (points fell short of 10)

The threshold is a hard 10. Nine of anything does not count, no matter how strong the rest of the line is. That is why you see players push for a single extra rebound or assist in the closing minutes.

Why the milestones matter

A double-double is a solid, common marker of a productive night, especially for big men who routinely score and rebound. Guards more often pair points with assists. Over a season, “he averaged a double-double” is shorthand for a player who reliably produces in two areas every night.

A triple-double carries more weight because it signals a complete, all-around game. Filling three columns usually means a player affected the game in scoring, rebounding, and playmaking at once. It became the signature of point-forwards and versatile guards who handle the ball, finish, and rebound their position and then some.

Still, the stat can mislead. A quiet 11-10-10 triple-double is not necessarily better than a dominant 35-point, 14-rebound double-double. The triple-double is a threshold, not a measure of impact, and a player can pad assists or chase rebounds to reach it. Coaches care more about winning the game than about which columns hit 10.

A note on the quadruple-double

Double digits in four categories is almost mythical. Because steals and blocks were not tracked as official NBA stats until the 1973-74 season, the quadruple-double has only been officially credited a handful of times. It usually requires an elite shot-blocker or ball-hawking defender having the game of their life, and even then it slips away by a single stat far more often than it lands.

If you want to understand a box score beyond the milestones, it helps to know how the underlying stats are defined. A rebound, an assist, and a steal each have specific rules for when the scorer awards them, and those definitions are what make a double-double or triple-double official rather than a matter of opinion.
