Guide to Padel Balls: Speed, Medium or Slow - and When to Use Each

You go to a sports store. There are three different brands of padel balls on the shelf. The price is roughly the same. You grab one on the right and assume it'll be fine.

It might not be. Padel balls are not all the same - and the wrong ball can do you a disservice, especially in cold weather or if you're at a specific skill level.

Here's what you should actually look for.

Speed, medium, or slow - what's the difference?

Most ball manufacturers make three types: speed, medium, and slow. The difference lies in the balls' internal pressure and the thickness of the felt layer.

• Speed balls have higher pressure and thinner felt. The ball is faster and bounces more. Suitable for players with good technical control, for indoor courts, and for warm weather.
• Medium balls are all-round. These are what most people use for daily practice. They perform broadly and are relatively predictable in most weather conditions.
• Slow balls have lower pressure and thicker felt. They allow more time to react. Suitable for beginners and for outdoor play in cold weather.

As a rule of thumb: the colder the weather, the slower the ball. Below 15 degrees Celsius, a slow ball is almost always the right choice.

Temperature and padel balls - an underestimated factor

A padel ball is filled with gas. Cold compresses the gas and the ball loses pressure. Heat expands the gas and the ball bounces more. This is physics - not a product defect.

What this means in practice:

• If you play indoors in winter with speed balls, you risk the ball behaving uncontrollably and quickly.
• If you play outdoors in summer with slow balls, they may feel heavy and sluggish.
• A 10-degree temperature difference can be equivalent to a whole level in ball tempo.

If you play outdoors in winter and the balls feel dead? They are probably not defective. They are cold. Keep the balls in your pocket before playing and warm them up. It helps.

Indoor vs. Outdoor - two different worlds

An indoor padel court is warm, dry, and controlled. This favors speed balls and medium balls. The game is fast, and the balls behave precisely.

An outdoor court is a different matter. Temperature, wind, and the surface of the court change the balls' behavior. Here, slow balls are a better choice in winter, and medium in summer.

Many players use the same ball type all year round. This is rarely optimal.

Which brands are most used in Denmark?

There's a difference in quality. The most used padel brands are:

• Head Pro - popular tournament ball, good durability, and consistent pressure
• Wilson - standard and reliable all-round ball
• Bullpadel - good pressure and fine felt durability
• Adidas Tour - used professionally, good for faster play

Brand is rarely crucial for recreational play. The most important thing is to choose the right type for your level and the weather. That makes a bigger difference than the brand.

When should you change your padel balls?

A padel ball typically lasts 4-6 hours of active play. After this, the pressure drops noticeably, and the felt begins to wear down.

You'll notice it by:

• The ball bouncing lower and more irregularly than usual
• The rebound from the glass being harder to predict
• You need to use more force to generate the same effect
• The felt looks thin and uneven

Most teams change balls approximately once a week with regular training. Tournament balls are changed even more frequently - professionals change after nine games. The reason is always the same: pressure loss.

What does it cost to play padel - and how to save

A can of 3 padel balls typically costs 60-80 DKK. If you play 3 times a week and change balls once a week, you'll spend 700-900 DKK per month - on balls alone.

That's a lot. And most of the balls are discarded not because the felt is worn, but because the pressure has dropped.

Pressurebox Pro automatically maintains the original pressure and gives you balls that play like new - session after session. It typically pays for itself in 1-2 months for an active player, and you can save up to 80% on your annual ball budget.

What happens to the pressure in padel balls - and what you can do about it

The rubber of the balls is porous. Air slowly escapes with each hit and with simple storage - whether you use the balls or not. It's inevitable, but it can be significantly slowed down.

Practical advice for your next ball purchase

• Check the temperature on game day and choose the ball type accordingly
• Always store balls indoors - not in the car boot
• Warm balls in your pocket before playing outdoors in winter
• Start with medium balls if you're unsure - they work in most situations
• Use a pressure container and refresh the balls instead of discarding them

Frequently Asked Questions about Padel Balls

Can I use tennis balls for padel?
Technically yes, but it is not recommended. Tennis balls are slightly larger and behave differently against the glass. Always use padel balls for padel.

What is the difference between indoor and outdoor balls?
It primarily concerns temperature and surface. Indoors it is warmer and faster - speed balls are most often relevant. Outdoors, it depends heavily on the season.

Can I refresh balls that have already lost pressure?
Yes. A pressure container like Pressurebox can restore pressure in balls that are not yet completely flat. The sooner you put them in after play, the better the result.

When is the ball too worn out anyway?
When the felt layer is visibly worn and the ball feels slick. Pressure won't help then. But most balls are discarded long before that point - solely because the pressure has dropped.

Should I buy expensive or cheap?
For recreational play, expensive brands are rarely necessary. Choose the right type (speed/medium/slow) and store them correctly. That yields better results than buying more expensive balls.
