Size guide

Every brand fits differently. An Adidas size 42 is not the same length as a Puma or Li-Ning size 42. To be sure of your choice, the most reliable method is to measure your foot and compare in centimeters.

How to measure your foot

  1. Place a piece of paper on the floor against a wall and stand on it, with your heel against the wall and wearing the socks you play in.
  2. Mark the tip of your longest toe.
  3. Measure the distance between the wall and the mark in centimeters. Do this for both feet and keep the longer measurement.
  4. In the brand's size chart, choose the size that is equal to or just larger than your measurement.

💡 Between two sizes? Go for the larger size: in basketball, your foot swells during exercise, and you play with thick socks.

💡 Already know your US size? That is the most reliable reference across brands.

Little Kids (3 to 7 years) and Babies

Jordan little kids' sets are indicated directly by age (3 years, 4 years...) and baby bodysuits in months (0-6 months, 6-12 months). If the child is tall for their age, choose the next size up.

Basketballs come in several sizes. Playing with the right size helps with dribbling, passing, and shooting, especially for young players.

Standard club sizes (FFBB categories):

Category Age Boys Girls
U7 (baby basket) 5-6 years Size 3
U9 (mini-poussins) 7-8 years Size 5
U11 (poussins) 9-10 years Size 5
U13 (benjamins) 11-12 years Size 6
U15 (minimes) 13-14 years Size 7 Size 6
U17, U20 and seniors 15 years and up Size 7 Size 6

💡 Summary: Size 5 for children up to 10 years old, size 6 for 11-12 year olds and for girls and women, size 7 for boys from 13 years old and men.

Differences between sizes

Size Circumference Weight
Size 5 approx. 69-70 cm approx. 470-500 g
Size 6 72.4-73.7 cm 510-567 g
Size 7 74.9-78 cm 567-650 g

Sizes 6 and 7: FIBA official regulation dimensions.

Indoor or outdoor?

  • Indoor (gym, parquet): leather or composite balls, better touch and grip. Avoid on asphalt, as it wears them out very quickly.
  • Outdoor (playground, asphalt): rubber balls, more resistant to wear.
  • Indoor / outdoor: versatile balls, a good compromise if you play everywhere.

Properly inflating your ball

  • Respect the pressure indicated on the ball, near the valve. It is usually between 0.5 and 0.6 bar (about 7 to 9 PSI).
  • The bounce test: drop the ball from about 1.80m high (eye level). When properly inflated, it should bounce back to between 1.20m and 1.40m, or about hip height. This is the official FIBA rule.
  • Use a moistened needle (a drop of water is enough) to avoid damaging the valve.
  • Do not overinflate: a ball that is too hard bounces too much, is hard to control, and wears out faster.
  • A ball loses some air over time: check the pressure regularly.

Maintenance

  • Clean with a slightly damp cloth, without harsh products.
  • Store at room temperature: not in a car in direct sunlight or outdoors in winter.
  • Do not sit on it or kick it: it can become deformed.
