As I’m sure you know, afootball is the most significant piece of equipment when playing football.

There are many different sizes of footballs and each is right for a various age group. 

For example, you wouldn't want to use a size 2 football when a child of a certain age should have a size 4. 

These reasons are why it's so important to understand how to choose a football size by age.

In this guide, we'll cover the different sizes of footballs by age and teach you how to choose the right one for your youth athletes.

Different Football Sizes by Age 

You may be curious why the size of a football matters. Many shoppers may not know why it matters when purchasing a football. This lack of knowledge might easily lead people to buy the wrong ball. Football balls differ in terms of construction, shape, and height.

Purpose Behind Football Sizes

Let's say we need the ball for practice rather than playing. To accommodate our needs, we should look for balls made for practicing purposes only. The official ball used for the match is way different from the practice ball. In terms of characteristics such as air, form, water absorption, slope, and trajectory, official match balls vary from practice balls.

Similarly, the construction and other features of the indoor, pool, and street balls differ.

Why Size Matters

Knowing the correct size for you or your child is essential. It is necessary because a ball that’s not the right size can possibly lead to injury. If a youth player kicks a size five ball made for adults daily, they are bound to sustain an injury. Only adult players can use a size five ball because of the pressure and diameter. 

It's not all about escaping injuries; a child might want a ball with the right bounce and weight for other required exercises. Therefore, while professional football players play with a size 5 pitch, they also use different skill development sizes.

Besides distinguishing which size best suits your football style, it is important to understand the purpose of each size. Most professional football players don't stick with one size. Instead, they may use a variety of sizes for different practice and skill training. To explain this thoroughly, we listed the five sizes available and their benefits as well as the best time to use them. 

Size 5 Football Age - 12+

The size 5 is the professional football that professional players use. It is an ideal football for players ages 12 and up, including adults. All regular, elite, and international football matches use the size 5 football. The size 5 football measures 27′′-28′′ in diameter and weighs 410-450 grams.

The ball is too big for children to handle, making it difficult for them to move. Also, it’s important to know that the size 5 is not intended for newcomers to the sport.

Size 4 Football Age - 8-12

The size 4 or a "medium" football is meant for an amateur in football games. Size 4 acts as a buffer between the small and huge footballs. Youth football players aged 8 to 12 primarily use a size 4 football pitch. The size 4 ball has a diameter of 25′′-26′′ and a weight of 350-390 grams.

The size reduction is suitable for this age range because it helps players become more comfortable with their skill sets. Any children aged 8 to 12 can technically play with a full-size professional football, but most of them would find it challenging to use a size 5. Therefore, size 4 will help children in this age range continue to train and develop without being hindered by the size.

Size 3 Football Age - 6-8 

The junior-level football games group usually uses size 3 footballs, while other adult professionals use this for skill training. The size 3 ball is an excellent choice because it encourages proper ball handling in children. It is also toned appropriately for most children of this age. This size area is 23-24 inches, while its weight varies between 11-12 oz.

Typically, this size is for children under the age of eight and safe for kindergarten students without any issue.

Size 2 Football Age - 3-5

The size 2 football is also known as a "skills ball" and used as a trainer ball. It is ideal for honing ball control, footwork, and ball-handling skills. Adults also use this size for ball control drills and to test the capability of the players' grip.

The size 2 Football is recommended for kids ages 3 to 5 years old and for older players who wish to use it for drills.

Size 1 Football Age - Toddler

The size 1 footballs are known as mini balls or skill balls. They’re usually used to train players in skill development and ball control. Anyone regardless of age can use this size to train and improve their skills.
