How Heavy Is a Basketball? Weights by League, Age Group, and Training Use

How heavy is a basketball? An official NBA ball is reported at about 22 ounces, or roughly 1.4 pounds.

Other leagues and youth levels use lighter balls, and weighted training balls run heavier. The figures here come from published pages and are approximate.

How Heavy Is a Basketball in Official Play?

Published pages on the topic agree on one headline figure for the top professional level, and the rest of this article builds outward from it.

How Heavy Is a Basketball Used in the NBA?

Published sources report that an official NBA basketball weighs about 22 ounces, which is roughly 1.4 pounds or 624 grams. Its circumference is listed at 29.5 inches, as reported by CBS Sports, and the standard cover material is leather.

The word about matters. Sources give the weight as an approximation, and exact manufacturing tolerances are not stated in the material reviewed for this article.

Players moving from a casual outdoor ball to a leather game ball often notice a change in feel. How much of that comes from weight and how much from the cover is not something these sources separate.

How to Read the Figures in This Article

Statements introduced as reported come from published pages on the topic. Statements introduced as general understanding are widely repeated explanations that those pages did not back with a source.

Gram and kilogram values are converted from the reported ounce and pound figures, so they are rounded.

No figure here has been checked against a league or federation rulebook. Anyone who needs an exact specification for a purchase or a competition should confirm it with the governing body.

The pound and gram columns are calculated from the reported ounce values and rounded. NBA basketball weight and WNBA basketball weight are the two figures people most often compare, and the gap between them in this table is about 2 to 4 ounces.

The WNBA range of 18 to 20 ounces matches the league playing rules, according to the WNBA.

Notes on the Figures

Figures Given as Ranges

The NCAA, WNBA, FIBA, and youth weights are reported as ranges, not single values. The sources do not explain why.

Different ball models, tolerances, or age categories are plausible reasons, but that is general understanding, not something the sources confirm.

What the Sources Do Not Specify

The reviewed pages give no age brackets for youth balls, no circumference for the FIBA ball, and no numbered ball sizes.

Parents buying for a child commonly check the size printed on the ball or its packaging, since the published pages say little about age brackets.

Why Basketball Weight Matters

Handling and Play

Published sources report that a ball that is too light may not bounce properly, while one that is too heavy is harder to handle and shoot. That is general understanding, and none of the pages supply test data to back it.

The reported lighter youth weight is described as making the ball easier for small hands to grip and shoot, and coaches of younger players commonly move to a smaller ball for that reason.

Consistency Across Competition

Using the same specification across a competition keeps results tied to player skill, a point made in the published pages. Recreational leagues often settle on a single ball for every game for much the same reason.

Inflation Pressure

Published sources give a recommended pressure of 7.5 to 8.5 pounds per square inch, checked with a small pressure gauge and adjusted with a standard pump. The NBA equipment rule lists the same range, according to NBA Official, though it words the unit as pounds pressure.

Pressure is a separate specification from weight. A ball that has sat unused for weeks often feels flat when picked up, and a gauge reading is the usual first step before play.

Weighted Training Basketballs

How Heavy Weighted Basketballs Are

Reported weights for weighted basketballs run from 2.8 pounds to 4 pounds, about 1.3 to 1.8 kilograms. The low end is described as twice the weight of a conventional ball.

They match a regular ball in size and have a similar look and feel, though cover materials vary. One commercial training ball is listed at 3 pounds with a synthetic leather cover.

One source calls the weight difference modest while also describing the lightest weighted ball as double a standard one. How noticeable it feels is therefore a matter of judgment more than measurement.

What Coaches Say They Are Used For

Two college coaches quoted in a published article describe weighted balls as most useful for passing and ball handling.

Both advise against using them for shooting practice, since shooting is already difficult and the added weight is not needed. Coaches who use them commonly place them early in practice, during skill work.

How to Read the Benefit Claims

Coach statements are opinions from experienced practitioners, not controlled studies. Product listings claim stronger fingers, wrists, and forearms and quicker responses between dribbles. Those are seller claims, and the pages reviewed offer no test results for them.

There is also a trade-off. A heavier ball adds difficulty, and one source cautions that beginners should learn fundamentals before adding extra load.

Who Uses Them and When

Published sources describe weighted balls as useful at any level, from beginners to professionals.

Coaches quoted say regular use matters more than the time of day or season. Players commonly fit one into drills they already run, such as passing lines, instead of building separate sessions around it.

Conclusion

An NBA basketball is reported at about 22 ounces, NCAA and FIBA balls at 20 to 22, WNBA balls at 18 to 20, and youth balls at 14 to 16.

Weighted trainers run 2.8 to 4 pounds. All figures are approximate, so confirm specifications with the governing body.
