How Much Air Pressure Should a Basketball Have to Bounce Properly?
Are you a regular basketball player that’s puzzled about why some basketballs bounce better than some others? Yeah right! So, you’re quick to conclude that the bouncing ability of the ball depends on the brand that produces it.
Thus, you think a Spalding is better than a Nike, Franklin, Champion Sports, MacGregor or Fanmats? And some other basketball players think otherwise—choosing the brand they love above others.
It’s typical for you to be biased and support your favorite brand as the best basketball manufacturer in the market. On that note, it will interest you to know that the brand has nothing to do with the bouncing deficiency of your basketball.
But here’s what we found out.
The amount of air pressure in your basketball contributes majorly to the bounce rate of your basketball.
We‘ll be talking extensively, in this article, about how much air pressure your basketball should have—for it to bounce correctly.![]()
Also, we would discuss other vital factors that contribute to the air pressure and bounce rate of a basketball.
Quick Navigation
What Happens When a Basketball Isn’t Bouncing Properly?
The obvious answer, right? If your basketball isn’t bouncing correctly, the first issue it creates is to hinder your game performance. But, beyond that, we need to go deep into the foundation of this problem and find out why your basketball isn’t bouncing correctly.
If you’re like us that recently found out that the amount of air pressure in a basketball determines its bounce level, then, we’re on the same page. But, if you haven’t, it is not too late to join the bandwagon.
Dealing with Air Pressure
The force that pushes air against every solid surface it comes in contact with is the air pressure. In simpler terms, the more air in an enclosed area, the higher the air pressure. If this theory is correct, that means you need an optimum amount of air in your basketball to get the best bouncing result on the court.
Before we move on:
Did you know that air is mattered? You heard, right! The air we breathe? Of course! But, you’re surprised because you have always thought that matter in quote had to be solid. At least, that’s what your science teacher taught you in mid-school—she told you, “Matter is anything that has got mass and occupies space.”
But here’s the cracker.
Air has weight, mass, and volume (You can ask your science teacher). What that means is air takes up space. So, you can see it fits into the definition. We know, it sounds weird to think of air as matter, when you can’t touch or run into it.
Think of it this way. Your basketball, bike tire, bouncing castle or air mattress get their mass and form because of the air and air pressure in them. In this case, it’s the air pressure in your basketball that gives your ball the round shape and bouncy feel.
Recommended Air Pressure Required for a Basketball to Bounce Optimally
The typical basketball requires at least a reading of 8 lbs(pounds by square inch) to get appropriately inflated.
If you’re lucky enough, you can buy a basketball that has the inflation instructions printed by the manufacturer to help you get the default air pressure of the ball.
If your ball is not far from you now, you can quickly go check it out and come back to the article. For instance, you may see something like “Inflate 7 to 9 psi.” You saw that, right? Don’t bother if you didn’t see it on your ball—not every manufacturer prints it on their basketballs.
NBA recommends that the air pressure in a basketball must be between 7.5 and 8.5psi. You can use this standard measurement as a guide to get the required air pressure for your basketball.
A quick way to check if your ball has the proper air pressure is by taking this simple test. Drop your basketball from the height of your shoulder and leave it to bounce. If it bounces up back to the height of your hips, then your ball probably has the appropriate air pressure required to deliver on the court.
Three Factors That Can Affect the Internal Air Pressure of a Basketball
Here are three primary factors that affect the bounce level of your ball.
1. Ball Pressure
When you properly inflate your basketball, you enhance its elastic bladder—making it capable of rebounding when it hits a hard surface like the rim. In essence, the higher the air pressure in your basketball, the higher its bounce and otherwise. But, you have to be wary not to over-inflate your basketball to avoid the bladder breaking, which will negatively impact the consistency of the ball’s bounce or even cause leakage.
2. Environmental Pressure
Most times, the surrounding air pressure around a basketball is equally constant, but you should always consider environmental air pressure as it always comes in play—affecting the bounce level of the basketball.
The air is usually less dense or thinner at higher altitudes. And when the air is less dense, objects aren’t still affected as much by the air resistance going against them—whether they fly or bounce through the air.
What this means is that air pressure from the surroundings will hardly affect your basketball enough to mar your game outdoors.
However, it contributes significantly to the height of your ball’s bounce. That takes us to the next factor.
3. Temperature
A decrease in temperature will result in a decline in air pressure inside your basketball. Plus, the bounce level of a basketball primarily depends on the air pressure inside a basketball—as we discussed earlier.
Thus, when a basketball hits and bounces on the floor of a gym with average room temperature, the force of the bounce impact pushes the bottom surface of the ball while compressing the gas inside it.
But here’s a kicker.
According to Boyle’s law, the pressure of the gas inside the basketball increases, when a ball bounces on a hard surface, especially when you’re playing at the park during summer.
But, it’s a different ball game in winter. The internal air pressure of a basketball decreases when it bounces on a hard surface.
Since the internal air pressure of the basketball decreases at a lower temperature, the impact of the ball with the ground will also have less effect when it hits the ground.
By that, the basketball does not bounce high enough as it does at a higher temperature.
In Closing
It’s wise to use a small pump and pressure gauge when inflating your basketball. A report showed that you need about 12 strokes to get something close to the perfect air pressure, which is around 7.5 – 8.5psi.
Thus, you should avoid using high-pressure pumps designed for cars and bike tires. They can easily over-inflate and destroy your basketball.
Of the three factors mentioned earlier in this article, which one struck you as the most important? Has that factor affected your game before? Have you damaged your ball previously because of over-inflation? Tell us your story; we’re eager to see your comments, suggestions, and feedback.
How Much Air Pressure Should a Basketball Have?
If you have played or watched basketball long enough, does it occur to you how much air pressure should a basketball have? Honestly, if you have not played basketball, you would think that it doesn’t even matter.
But if you have played the sport, you would know that some balls bounce a lot better than others. Is it because of the brand? It could be a factor, but perhaps the most crucial element is air pressure.
Does it Matter How Much Air is In Your Basketball? We hate to answer with a little sarcasm, but aren’t we also concerned about how much air is in the balloons at some kids’ party? Or about how much air should be in our car tires? The answer is, of course, a resounding, yes! It would only be natural to prefer one basketball brand over another, but the main factor contributing to how good (or bad) your ball bounces is the air pressure.
What, then, is air pressure? It is the force or push of the air against anything that it comes in contact with. In this case, it is the leather or the rubber in a basketball. The more air there is inside, then the air pressure increases.
Needless to say, a basketball player should be worried if the ball is not bouncing correctly.
It does slow your performance down, whether we are talking about shooting, dribbling, or the accuracy of passes. A basketball player that feels uncomfortable with how the ball bounces quickly becomes distracted and may even lose confidence throughout the game.
How Do You Measure Air Pressure in Basketball? You can measure air pressure in a basketball by using an air pump with a built-in pressure gauge. The recommended air pressure for a basketball is 7.5 to 8.5 psi (pounds per square inch). That is also the NBA basketball air pressure recommendation. As you can see, there isn’t a fixed air pressure endorsement by the NBA, but you can use this recommendation as a guide to getting the right air pressure.
How Much Air Pressure is in a NBA Basketball? As previously noted, the NBA basketball air pressure instruction is between 7.5 to 8.5 pounds per square inch. Some balls have air pressure recommendations printed in them, and it may state “up to nine pounds,” but obviously, the NBA prefers it to be just a little lower than the maximum allowable air pressure in a ball.
In the case of FIBA, the international governing body for basketball did not specify a pressure range. Instead, it indicates that the ball should bounce between 1,200 to 1,400 mm (47.2 to 55 inches) when dropped at the height of 1,800 mm (or approximately 70 inches). In addition to the “ball bounce” test, FIBA rules also mandate that the balls be subjected to fatigue strength, valve leak, practice, and heat storage tests.
Ironically, even with NBA basketball air pressure recommendations, the balls are rarely measured during games. That is because most pumps that are used do not have gauges, and even if they do, it does not accurately indicate air pressure. From that standpoint, FIBA’s “ball bounce” instructions appear to be a sound and practical procedure in determining the right basketball air pressure.
Will More Air in a Basketball Bounce Higher? Yes, more air in a basketball makes the ball bounce higher. Why? Because as you inflate the ball, the more compressed the air becomes so it can fit inside.
Now, as it becomes more compressed, the air presses the inside of the ball with more force. If you are dribbling the ball, it produces a pushing action even more inside the basketball. The air pushes back, so to speak, with force equal to the amount of air pressure in the air. (This is known as the Third Law of Motion that briefly states: “In every action, there is always an equal and opposite reaction.”) That force is what thrusts the ball back up. If there is more air inside the basketball, it pushes harder back up when the basketball is bounced.
Again, the short answer would be, yes, it makes the ball bounce higher. But then again, it doesn’t hurt knowing the science behind it.
Does Temperature Affect the Bounce of a Basketball?Yes, the temperature can affect the way a basketball bounces. Since we have already talked a little about science, then perhaps, we should continue on with it. It involves what is called the Ideal Gas Law, a combination of natural laws discovered by Boyle, Charles, Avogadro, and Gay-Lussac.
It states that there is a specific relationship between volume, pressure, and temperature in a confined system. To cut the geeky story short, it means that when a basketball is subjected to increased temperatures, the volume of the air pressure inside increases. The opposite is also true: If exposed to colder temperatures, a basketball’s air pressure decreases.
Understanding the concept of the Ideal Gas Law will make you aware of the playability of the ball. From that Law, we can assess that a temperature change of plus-10 degrees Fahrenheit can increase the pressure by a pound per square inch. Conversely, if you played in an environment that is 10 degrees colder, the basketball’s air pressure drops a pound per square inch. In the latter conditions, say, a ball has been inflated to 8 psi. It follows, then, that playing in such circumstances will drop the ball’s air pressure to 7 psi, a tad below the minimum recommended NBA basketball air pressure of 7.5 psi.
How Can You Tell if a Basketball is Pumped Enough?It is pretty easy if you have an air pump with a gauge, but the thing is, gauges are also inaccurate to a certain degree.
That is probably why the NBA gave a recommendation range of 7.5 to 8.5 psi to provide a room for error. All that being said, we think FIBA’s ball-bouncing recommendation should tell you if a basketball is pumped enough if you can’t find a gauge.
Does the Air Pressure in a Basketball Affect Your Shot?This is a tricky question, and while we are inclined to say yes, air pressure does affect your shot, it might not be accurate in all cases. Air pressure may affect the result of the shot, but it should not affect your mechanics as long as it’s not too soft or squishy to the touch. It should not change the trajectory of the ball, either.
Now, how can air pressure affect the outcome of your shot? It’s because basketballs with higher air pressure often bounce farther off the rim while the ball with a lower air pressure has a higher chance to ricochet in or bounce near the basket. So, air pressure may affect how a ball bounces off the rim rather than affecting the shooting mechanics or the ball’s trajectory.
Wrapping Things Up: How Much Air Pressure Should a Basketball Have? A basketball should have the right air pressure for the players to feel comfortable handling it. Many will write off the importance of putting the correct air pressure on a basketball, but in reality, it is an essential part of the game. If the players are not comfortable with how the ball bounces during a live dribble, it can negatively influence his overall game.
There are really no rules on how much air pressure is needed in a basketball. If you’re just playing pickup or recreationally, it may all boil down to the preferences of the players. However, in the NBA, the recommended air pressure is between 7.5 to 8.5 pounds per square inch (psi).
In FIBA, they use a somewhat instinctive rule that a ball should not bounce higher than 70 inches and no lower than 47 inches. In our opinion, FIBA’s rule is a lot simpler and maybe even more accurate since air pressure gauges are not usually around.
If there are gauges lying around, they may also not give the precise air pressure reading.
What many did not know, though, is that temperature can affect the air pressure in the ball. How so? Because of the Ideal Gas Law, it is found that a difference of 10 degrees Fahrenheit can approximately increase or decrease the air pressure by 1 psi. Knowledge of this natural law is essential, especially in the NBA. That’s because playing in certain temperatures can reduce the air pressure of the ball below the league’s recommended range.
Now, if you’re wondering whether the ball’s air pressure can affect your shot, the short answer is no. It should not affect your mechanics as well as the trajectory of the ball. The issue lies in what happens after the shot. Simple physics suggests that a ball with too much air pressure bounces farther from the rim while the ball with the lower air pressure will likely bounce near the basket. All of these factors should be taken into consideration when we’re talking about how much air pressure should a basketball have.

Respect! You can't sit on an inflated basketball and hit it with your feet, like a football, with the force of throwing a ball on a hospital object - as a result of this ball, it quickly loses its shape and comes into disrepair.
Inflate a basketball in the appropriate manner: put 1-2 drops of special oil on the opening of the nipple or the neck, take the ball by the panel, where the nipple is located, insert it into the new neck, inflate the ball to the value indicated in the vice tables.
We strongly recommend vicarious oil. Special oil is not only ahead of valve slippage and nipple walls, but it also makes the material of the nipple more elastic, protecting it from drying out.
The head is also due to a special buti for inflating balls, and the tip of the head is due to buti equal, smooth, without sharp edges and burrs.
ATTENTION! Always vicorate the vowels for the nipple or the ball, in the other case, you risk damaging the nipple and lose it without a ball.
The amount of grip that is recommended for balls made of different materials and in different types of winding:
| Riven gri | Recommended vice (bar) | Recommended vice (psi) |
| Basketball rubber balls, size 5-7 | 0.7-0.9 | 10-13 |
| Basketball rubber balls, size 3 | 0.6 | 8-9 |
| Basketball balls made of natural and synthetic skins, size 7 | 0. 7-0.9 | 10-13 |
| Basketball balls with natural and synthetic skins, sizes 5 and 6 | 0.7-0.8 | 10-12 |
It is recommended to check the vise in the balls after the help of the monometer.
Rolling the ball creates a pressure and over the world stretching tension on the materials, from such preparations of the ball, with which the term of the ball's service is very fast.
Rolling the ball also negatively affects the game characteristics of the ball, first for everything on yoga.
Take care of that sight.
- After skin irritation wipe the ball with a damp cloth. At the time of the strong, vicorist fabric, soaked in a warm miles pink. Do NOT at any time do not beat up abrasive cleaning cats, and also take care of the retailers and aggressive speech.
- Let the ball dry naturally. If the ball is already wet, wipe it with a soft cloth. Dry the ball in a well-ventilated room, give it heat, at a temperature of + 20-25 ° C and a moisture content of 60-65%.
Avoid direct sleepy changes and do not dry the ball nearby, or on the surface of the scorching devices. Trivals of mud, water, increased temperature lead to an increase in the physical powers of the ball and, as a result, its game characteristics, short term of service. - It is recommended to store the balls in a dry ventilated area at a temperature of 5-25 C and an air humidity of 50-80%. The balls are due to protection from falling direct sleepy exchanges, diva, gases and chemical speeches.
- Balls made of synthetic and composite skins should be taken away and transported in a puffed-up look. In the other case, the deformation of the material of the coating and the opening of the panels is possible.
Thank you for the miraculous smile and brilliant wins! :)
Ball inflation pressure
Ball inflation pressure
A properly inflated ball is the key to a good game and durability. If the ball is not sufficiently inflated, then this will entail a low rebound, poor handling, and an incorrect flight path.
If the ball is pumped over, it can burst, change shape, cause pain during the game, and even cause injury.
First of all, when buying, carefully check the ball for mechanical damage, whether the ball is new and how it is packaged. Most often, the cause of the pressure drop in the ball is a damaged nipple. If you purchased the ball in a deflated state, then be sure to inflate it according to the instructions, checking the pressure, and leave the ball overnight. Check the pressure again the next day. If you bought the ball in an inflated state, then leave it for a day and see if it went down during this time. You can also use the "old Russian way" to determine the health of the nipple. To do this, moisten your finger and attach to the nipple. A properly functioning nipple will not form bubbles. We draw your attention to the fact that if you purchased the ball and used it, then the guarantee for such a ball remains only after the provision of an expert opinion.
Back to pressure.
.. The pressure in a ball depends on what sport the ball is for, what size it is, and what level of play it is. Different manufacturers measure pressure in different units, psi (pounds per square inch), bar (pressure unit approximately equal to one atmosphere), kgf / cm² (one kilogram of force per square centimeter), kPa (kilopascal). Pay attention to this!
The pressure in the ball is strongly influenced by the ambient temperature and atmospheric pressure. If we recall physics, then at high temperatures the substance expands, and at low temperatures, on the contrary, it decreases. So if, in winter, we pump up the ball on the street at -10 to the desired pressure, then after we bring the ball into a warm room, the pressure in it will increase slightly. This is true, for example, for soccer balls for games in winter. Therefore, it is better to inflate the ball directly where games or training are planned. If the operating pressure recommended by the manufacturer is not observed, the performance of the ball will be significantly worse and the ball will become unusable very quickly.
