If you are just starting to play table tennis or just practicing, it’s pretty normal to look for the best ping pong balls. However, to choose the best ball with so many table tennis ball types around is undoubtedly difficult since every ping pong ball seems to be identical to the naked eye.

We have to keep in mind the measurements, weight, diameter, etc. However, no worries, we are here to help you to understand every aspect of ping pong balls and how to choose the right one for your requirements.

Different Measurements of a Ping Pong Ball

Ping Pong balls are available in various colors and even sizes. But most importantly, they are graded by stars; one-star ping pong balls are made for kids or school use since they are much softer than professional balls and available in different colors in 4cm of diameter.

The two-star balls are best for practice and trails and even can be used as a last resort in a game if the weight is correct and has a diameter of 4cm.

And finally, the three-star balls have been used in all international tournaments and the choice of a serious player.

Though these tiny spherical balls look the same, they have precise measurements and sizes to get to the distributors. The ping pong ball’s generally known diameter is 4cm, i.e., 1.57 inches or 40mm.

The dimensions of a ping pong ball are 1.5 x 1.5 x 1.5 inches. Although the old official ping pong balls made of celluloid are 3.8cm or 1.5 inches, Olympics games have changed the celluloid balls to plastic polymer balls since they are not much durable.

Weight of a Ping Pong Ball

The weight of a ping pong ball is an important feature. If there is a slight change in the ball’s weight, it affects the ball’s bounce, and it also determines the force required by a player to get the ball over the net.

All ping pong balls are hollow inside, and they only contain air, which is why they are so lightweight. The ping pong ball’s ideal mass is 2.7g or.095 ounces, and the radius is 20mm, while the volume of a ping pong ball is approximately 33.5cm3.

How Much Ping Pong Balls Could Fit in a Boeing 747

So here comes the fun part. To know how many table tennis balls could fit in a 747 airplane, we multiplied the persons in volume in the plane (which is around 3000) to the 10,368 cubic inches, and that way, we get 31,104,000 cubic inches of space available.

In the case of a ping pong ball that holds three cubic inches, we can divide the available space by the volume occupied by one ping pong ball, and that way, Boeing 747 can have 10,368,000 balls.

But since the spheres do not fit in an exact measurement, let’s take 70% of the answer, and we will get around 7-8 million balls in a Boeing 747.

However, let me put it in a simple way for a quick understanding. Depending on the bus’s size and the size of a single ping pong ball with the volume, an empty school bus is assumed to fit around 1 to 1.2 million balls to fill the entire bus.
