Football sizes range from Size 1 to Size 5. Each size fits a specific age group and playing level. Knowing the right size helps players develop faster and play safer.
What Are the Official Football Sizes?
Official football sizes go from Size 1 to Size 5. Size 5 is the full-size match ball. Sizes 1 through 4 are used for younger players and skill training.
Size 1 Football — Mini and Skills Ball
Size 1 footballs are the smallest available. They measure around 18 to 20 inches in circumference. Kids under age 4 use them, but adults also use them for foot skill drills and juggling practice.
These balls are lightweight and easy to control with one foot. Many coaches use mini footballs to improve touch and close control. Brands like Adidas and Nike sell Size 1 balls as gift sets and promotional items.
Size 2 Football — Toddler and Training Ball
Size 2 footballs measure 21 to 22 inches in circumference. They weigh around 250 grams. Toddlers between ages 3 and 6 are the primary users.
This size is also used for street football skills and freestyle training. It is small enough for young hands but still round enough for basic kicking patterns.
Size 3 Football — Young Kids Ball (Under 8)
Size 3 is the smallest match ball used in organized youth games. It measures 23 to 24 inches in circumference and weighs between 300 and 320 grams. Players under age 8 use this size in the USA.
U6 and U8 leagues across the country follow this youth football size standard. A lighter ball at this stage helps young players develop proper kicking technique without strain.
Size 4 Football — Youth Ball (Ages 8–12)
Size 4 footballs measure 25 to 26 inches in circumference. They weigh between 350 and 390 grams. This is the standard ball for players between ages 8 and 12.
Size 4 is also the official futsal ball size used globally. It is smaller and heavier than a Size 5, which improves control on indoor courts. US Youth Soccer recommends Size 4 for U10 and U12 age groups.
Size 5 Football — Full Size Official Ball (Ages 13 and Up)
Size 5 is the official match ball for all professional and adult competitions. It measures 27 to 28 inches (68 to 70 cm) in circumference. The weight sits between 410 and 450 grams with a pressure of 8.5 to 15.6 psi.
FIFA mandates Size 5 for all official match play including the World Cup and MLS. Every player aged 13 and above should train and play with this size.
Football Size Chart by Age Group (USA Guide)
Matching football size to age is the most important buying decision. Using the wrong size slows development and increases injury risk.
Football Sizes for Toddlers and Kids Under 8
Children under age 8 need a small, light ball. Size 3 is the go-to for U6 and U8 leagues in the USA. Size 1 and Size 2 work well for backyard play and early skill building.
A lightweight ball protects young joints. It also makes first touches easier and builds confidence on the ball faster.
Football Sizes for Youth Players Ages 8 to 12
Players in this age group use Size 4. It fits their body size and strength level. US Soccer and US Youth Soccer both confirm Size 4 as the correct youth match ball for this bracket.
Moving to Size 4 at age 8 prepares kids for structured league play. It also builds the passing and shooting habits needed for the next level.
Football Sizes for Teens and Adults Ages 13 and Up
Anyone 13 and older plays with Size 5. This includes high school, college, MLS, and amateur adult leagues. It is the universal adult football size across all skill levels.
Most training sessions at this level also use Size 5. Occasionally, smaller sizes are used for warm-up drills and technical work.
