Football size corresponds to player age, but ball size for youth football leagues can differ by location and league standards—we recommend confirming ball size with your league or association. In general, here are the appropriate sizes for age groups:

• Size 5: Adults (U12+), ages 13+ | 27–28in. (68–70 cm)
• Size 4: Youth (U8–U12), ages 8–12 | 25–26in. (63.5–66cm)
• Size 3: Junior (U5–U8), ages < 8 | 23–24in. (58.5–61cm)
• Size 1: Skills training, all ages | 18–20in. (46–51cm)
