The size selection of children’s PVC baseball should take into account the child’s age, physical development and motor ability to ensure safety and user experience. The following are specific suggestions for size selection:
First, classify the size by age and body type
Young children (3-6 years old)
Suggested diameter: approximately 6.5 cm to 7 cm. This size is smaller and lighter, making it easier for children to hold and reducing the risk of dropping the ball due to its excessive size.
Suggested weight: Approximately 100 to 120 grams. Lightweight design can reduce the difficulty of hitting and avoid muscle strains caused by excessive weight at the same time.
Design features: Anti-slip textures can be added to the surface or soft PVC material can be used to enhance grip stability.
School-age children (7-12 years old)
Suggested diameter: Approximately 7 cm to 7.2 cm. This size is closer to a standard baseball, which helps children gradually adapt to the formal game ball.
Suggested weight: approximately 120 grams to 140 grams. Moderately increasing the weight can enhance the feedback of hitting the ball and help children master the power generation skills.
Design features: Maintain a medium-hardness core, balance elasticity and durability, suitable for daily training and light competitions.
Second, adjust the size according to the usage scenario
Enlightenment training
Suggested diameter: 6.5 cm to 7 cm. The small-sized sphere is easier to control and is suitable for beginners to practice basic movements such as throwing, catching and hitting.
Suggested weight: 100 grams to 120 grams. Lightweight design can reduce the error rate and enhance children’s self-confidence.
Advanced training
Suggested diameter: 7 cm to 7.2 cm. Gradually transition to the standard size to help children adapt to the flight trajectory and hitting feel of the match ball.
Suggested weight: 120 grams to 140 grams. Moderately increasing the weight can enhance the training intensity and prepare for the official competition.
Third, considerations of safety and durability
Material selection
Outer layer material: Soft and impact-resistant PVC material is adopted to prevent children from getting injured due to collisions.
Core material: Select materials with moderate elasticity (such as cork + rubber composite core) to ensure that the rebound force will not be too strong when hitting the ball.
Structural process
Sewing process: High-density sewing thread is used for reinforcement to prevent the ball from cracking or the inner core from being exposed.
Surface treatment: Add anti-slip texture or coating to enhance grip stability and reduce the risk of dropping.
Fourth, comprehensive suggestions for size selection
Dynamic adjustment: Based on the actual usage feedback from children (such as grip comfort, hitting difficulty, etc.), adjust the size and weight of the ball in a timely manner.
Professional guidance: Choose the size under the advice of a coach or professional to avoid sports injuries or technical deviations caused by improper size.
Gradual transition: From lightweight and small-sized spheres for young children to standard-sized spheres for school-age children, helping children improve their skills step by step.
