International Volleyball Federation (FIVB) Standards

According to the FIVB, the standard size of volleyballs used in official matches is 65-67cm in circumference and 260-280g in weight.

Also, the internal pressure of the ball is required to be 0.30-0.325 kg/cm² (kilograms per square centimeter).

Balls of this size are used in adult international games and the Olympics for both men and women.



Ball size according to age group and level

  • Youth level (elementary school) : In games aimed at younger players, a slightly smaller ball may be used. This is to adapt to children’s hand sizes and improve playability. For example, in the category of U-12 (12 years old and under), which is elementary school students, we use a ball with a circumference of 63-65 cm and a weight of 200-220 g.

  • Recreation : For recreational and beginner play, balls of the same or slightly larger size may be used. This is intended to make it easier to handle the ball and enjoy the game.



Size of volleyball used by elementary school students


The size of the volleyball used by elementary school students may vary depending on their age and skill level.

Generally, the size is smaller than the standard adult volleyball as defined by the International Volleyball Federation (FIVB).


Volleyballs are generally size 4 or 5 balls. A size 5 ball is the size of a standard adult volleyball, with a circumference of 65-67 centimeters and a weight of 260-280 grams.

On the other hand, a slightly smaller No. 4 ball is recommended for elementary school students, and this size has a circumference of 62-64 cm and a weight of about 230-250 grams, making it easy for elementary school students to grasp and operate. It is designed to.


However, it’s important to check the rules of your team or local league, as the recommended ball size may vary depending on your specific age group or organization.

They may also use balls of special sizes and weights for training purposes.

This is aimed at improving players’ skills, and it is recommended to select the appropriate ball according to the actual match or training.




Size of volleyball used by junior high school students


Junior high school students usually use a size 5 volleyball, the same size as adults.

This size is the standard size prescribed by the International Volleyball Federation (FIVB), with a circumference of 65-67 centimeters and a weight of 260-280 grams.

Middle school volleyball programs and competitions commonly use this standard size ball to help players transition smoothly to high school and adult level competition.


This size 5 ball has the right weight and size and is suitable for practicing skills such as spiking and serving.

Also, volleyballs used by middle school players often have slight pressure adjustments and may be made a little softer to suit training and match needs.


The most important thing for middle school players is to hone their technique and tactics, and choosing the right ball size to use can help develop these skills.

I think it’s a good practice method to change the size of the volleyball you use to match your practice menu.



Size of volleyball used by high school/university and above (adults)


The size of volleyball used by high school students, college students, and adults is the standard size 5 ball determined by the International Volleyball Federation (FIVB).

This size is commonly used in high school, college, professional levels, and amateur adult leagues. The specifications of the size 5 volleyball are as follows:

  • Circumference: 65-67cm
  • Weight: 260-280g


Size 5 volleyballs are the most common size for competitive play and are used for official games for all ages.

This size is designed to help players hone their technique and perform optimally during matches.


In addition, I will briefly introduce the sizes of soft volleyball and beach volleyball.


soft volleyball size


Soft volleyballs differ from regular volleyballs in that they are made of softer and easier-to-handle material, making them easier for children and beginners to play.

Although there are some differences in size compared to regular volleyballs, specific size regulations based on official international rules are often different.


The size of soft volleyballs varies slightly depending on the manufacturer and the organization using them, but in general, most soft volleyballs have a circumference of about 60 to 65 centimeters.

This is close to the standard volleyball size 5 (65-67 cm in circumference, 260-280 g) defined by the International Volleyball Federation (FIVB), but as the name suggests, soft volleyballs have a softer feel and are heavier. It’s also lighter, so you can enjoy it more safely.


Soft volleyball is especially popular in children’s physical education classes and recreational activities.

It is also widely accepted as a sport that can be easily enjoyed outdoors, such as in parks.

Its softness and lightness reduce the risk of injury and make it easy for beginners and children to handle, making it a fun way to learn basic volleyball techniques.


The exact size and weight of a soft volleyball will vary depending on the brand and model of soft volleyball used, so it is recommended that you refer to the specific product information or check the specifications before purchasing.


beach volleyball ball size


Beach volleyball balls have different characteristics than indoor volleyball balls, and have special standards in terms of size, weight, and material.

According to the International Volleyball Federation (FIVB), the official ball size for beach volleyball is 66 to 68 centimeters in circumference and weighs 260 to 280 grams.

This is slightly larger than an indoor volleyball ball, and beach volleyball balls have lower air pressure, which makes them feel softer.


Because beach volleyball is played on sand, the ball is susceptible to external conditions, especially wind.

Therefore, beach volleyball balls are designed to be more controllable and less affected by wind.

The materials have also been specially selected to ensure that they do not absorb water easily and remain durable even in sand and sun.


Due to its properties, beach volleyball balls are optimized for play on the beach and help players perform well even in the sand.

These balls are also suitable for learning strategies and techniques specific to beach volleyball.




Air pressure is also important for volleyball balls.


In addition to the ball size, it is also important to inflate it to the correct air pressure (especially for soft volleyball and beach volleyball).

According to the FIVB, air pressure in volleyballs used in official matches must be between 0.30 and 0.325 kg/cm² (kilograms per square centimeter) or 4.26 and 4.61 psi (pounds per square inch).

By maintaining this precise air pressure, the ball provides the right bounce and control, allowing players to execute techniques accurately.
