Padel balls are the same size as tennis balls. However, the air pressure is slightly lower with padel balls. Otherwise, everything is the same: rubber inside, felt outside. That's why padel balls are slower than tennis balls. At first glance, padel balls are therefore hardly distinguishable from tennis balls.
However, you can see the difference when you drop two balls at the same time. The padel ball does not bounce quite as high as the tennis ball.
The standard colour of padel tennis balls is yellow. Of course, a padel ball is also available in other colours, e.g. for training purposes. But for padel tournaments, the official yellow felt balls are used.
The diameter of a padel ball should be between 6.35 and 6.67 cm. The weight of a padel ball should be between 56.0 and 59.4 grams. Of course, this is also all in the Padel rules regulated.
Among the Padel outfitters there are many that also have padel balls in their range.
