Why Do Soccer Balls Lose Air?

As active football players and fans, we often get so immersed within the game that we tend to forget to look after about some of the vital components that make the beautiful sport what it is.

Today’s article shall pay particular focus to the soccer balls that get kicked and rolled on the pitch, with special emphasis on why their condition slowly deteriorates.

Let’s start with a short answer summary on why these objects lose air pressure over time.

Soccer balls lose pressure over time because they are not air tight. The inner bladder and valve components of a ball leak air gradually over its lifespan and, improper aftercare such as playing on unsuitable surfaces; inflating the ball to the incorrect pressure and failing to deflate when storing also contribute to gradual air loss.

Let’s now look at these things in more detail.


Ball material is not air-tight

Footballs have an internal component called a bladder which is used to hold the air together inside it.

I’ve gone into greater depth about this within my best soccer balls article which you can check out.

But the quick gist of things here is that butyl and latex type bladders are both unable to keep all the air trapped inside for the entire lifespan of the ball.

Although it must be said that the former material is more adept at air retention than the latter.

So, as a result of there being greater air pressure inside the ball than outside of it – due to inflation – there is a battle for equilibrium which plays out.

As the ball is not air tight, stabilization and balance are ultimately achieved by the ball passing out that inflated air over time.


Valve leakage

Additionally, footballs are known to have a valve opening which is used as a pumping mechanism.

I’m sure you’ve heard of a famous movie quote that goes something like…

“What goes in must come out”.

Well, this is actually true when it comes to soccer balls losing air.

The valve which allows for air to make its way into the football is the same valve that gradually lets air exit from it too.


Keeping your ball in good condition

Now I’m sure you’re probably wondering…

How do I stop a ball from deflating?

So, I’ve outlined a couple of extra tips in this article that – if followed correctly – should prolong the lifespan of any football you buy.

Let’s get down to it!


1. Deflate the ball when storing

Whenever you don’t intend to use the football for a couple of weeks, it’s a good idea to leave it in a deflated state as this relieves the pressure and keeps it strong for the times when it’s actually needed.

By using a pump, you simply place the accompanying needle into the valve and let the ball pressure leak out.

2. Use the ball on suitable surfaces

Don’t be one of those people that plays with a soccer ball on concrete, gravel or asphalt!

It certainly won’t do your ball any good.

Stick to surfaces like grass and artificial turf, as these are the kinds of terrain that your soccer ball was designed for.


3. Inflate to the correct pressure

A lot of manufacturers use fine print to indicate how much air needs to be inserted for optimal ball performance.

So, have a keener eye and take a look at the stated pressure level on your soccer ball.

FIFA’s own regulations specify that a size 5 ball should not exceed 15.6 pounds per square inch (PSI).

But I’ll also drop a brief video where you can see things in action for yourself:


4. Try some soccer ball sealant

In a case where your ball has a tiny puncture and you’ve identified the opening by submerging it in water, you can use a ball repair sealant to fix the air leakage.

Spray the sealant into the ball through the valve and allow for an even distribution of the liquid throughout the bladder by bouncing the ball a couple of times.


5. Ensure proper valve care

The needle that is usually inserted into the valve is slightly sharp and if the opening is not smooth enough to penetrate through, the outer material of the needle can puncture the inner lining of the valve.

Therefore, you’ll want to make sure that the valve opening is well lubricated with silicone or glycerine oil whenever you’re attempting to inflate it.



This article should have educated you on why soccer balls lose air.

In case you didn’t manage to pick up on that, I’m going to leave you with a short summary that should be easy enough to remember…

Soccer balls lose air pressure over time firstly because the outer material construction is not air-tight, meaning that over a certain duration of time the air will gradually seep out. More so, air leakage occurs due to the presence and nature of the valve opening, which is used to inflate the ball in the first place.

If you don’t want to extend its use by re-inflating, then just consider recycling it.

On a separate note, the topic of how long your soccer ball will last without losing air is pretty much dependent on your own playing experience.

And you can can maintain its combined pentagonal and hexagonal look for even longer with the right aftercare.

However, if you have a dog that likes to play soccer, you could be looking at a much shorter lifespan for your soccer ball.
