May 3, 2023 | 2 min of reading
The soccer ball is the fundamental object that accompanies fans of this sport around the world. Used in millions of games and tournaments, the soccer ball has undergone evolution and refinement over the years. In this article, we will explore the secrets behind its creation, discovering the materials and components that determine its shape and performance
.- Outer shell:
- The outer shell of the soccer ball is what is perceived by the players and gives it its shape and texture. Traditionally, the outer shell was made of leather, but over the years it has been replaced by synthetic materials such as polyurethane or PVC. These materials are durable, waterproof and offer greater resistance to abrasion during use on different types of gaming surfaces.
- Inner layers:
- Inside the soccer ball there are several layers that give the ball its shape and its rebound characteristics. The first layer is usually an inner lining made of fabric or synthetic material, which helps maintain the shape of the ball. Above the lining, there are one or more layers of fabric or rubber that provide the desired rebound and reactivity .

- Air chamber:
- The air chamber is the element that gives the ball its main characteristic: internal pressure. The inner tube is usually made of latex or rubber and is inflated through a valve placed on the outer shell. Air pressure may vary depending on tournament preferences and specifications, but is usually around 0.6-1.1 bar (8.5-15.6 psi
).
- Stitching:
- The seams of the soccer ball are one of the most important details in the manufacturing process. Traditionally, soccer balls were sewn by hand, but today most balls are sewn using high-precision machines. The seams serve to join the outer shell and provide greater strength and durability. Usually, modern soccer balls have seams that form a hexagonal or pentagonal structure , creating a distinctive pattern.
- Weight and dimensions:
- According to official rules, a soccer ball should weigh between 410 and 450 grams and a diameter of 68-70 centimeters. However, the weight and size may vary depending on the age of the players and the type of competition. For example, the balls used in youth games may be lighter
