Material and Construction

Ping pong balls are typically made from a type of celluloid or similar plastic material.

The construction of the ping pong ball is also designed to ensure consistency and durability, as well as to meet the ITTF regulations.

Color Options

While the most common color for ping pong balls is white, they can also be found in other colors. In competitive play, white ping pong balls are typically used, as they provide good visibility and contrast against the table and the players’ attire. However, for recreational purposes or themed events, you may come across ping pong balls in various colors such as orange, yellow, or even novelty designs.

Alternative Sizes

While the standard size for ping pong balls is 40 millimeters, it’s important to note that there are alternative sizes available as well. For instance, there are larger ping pong balls with a diameter of 44 millimeters, which are commonly used in some Asian countries. These larger balls are known as “Asian” or “Chinese-style” ping pong balls. Additionally, there are smaller ping pong balls with a diameter of 38 millimeters, often referred to as “mini” ping pong balls.
