Buying sports balls for children and adults: how to choose without making the wrong purchase

Buying a ball sounds simple, until you have to choose between different sizes, materials and intended uses. For children, a ball that is too heavy or too large can be difficult to control. For adults, a soft children's ball may not be suitable for serious training. Playing outdoors also places different demands on a ball than playing in an indoor sports hall.

Pay particular attention to these three common pitfalls:

  • Choosing the wrong size: a size 7 basketball is intended for older children and adults, while younger children have better control with a size 3 or size 4. Footballs follow a similar sizing system.
  • A smooth surface with limited grip: especially on tarmac, wet grass or a playground, you will quickly notice whether the ball has enough texture.
  • Incomplete sets: some balls are supplied uninflated and do not include a pump or needle. Always check exactly what is included in the packaging.

Which sports ball size is right for the player?

The right size depends on the sport, the player's age, hand size and level of play. Age recommendations are a useful guide, but if you are buying for a club or competition, also check the relevant regulations.

Basketball sizes in practice

  • Size 3 basketball: approximately 57 cm in circumference. Suitable for young children.
  • Size 4 basketball: approximately 65 cm in circumference. A practical choice for younger players.
  • Size 5 basketball: approximately 70 cm in circumference. Designed for children and junior players.
  • Size 7 basketball: approximately 75 cm in circumference. The usual size for boys from around 12 or 13 years old and adults.

A rubber basketball is generally suitable for outdoor use, for example on concrete, tarmac or a driveway. An indoor basketball may have a different surface and grip. If you want one ball for several situations, look for a model specifically described as an indoor and outdoor sports ball.

Football sizes for children and adults

  • Size 3 football: approximately 58.5 to 61 cm. For young children and developing basic ball skills.
  • Size 4 football: approximately 63.5 to 66 cm. Commonly used by players aged around 8 to 12.
  • Size 5 football: approximately 68 to 71 cm. The standard choice for older children and adults.

A waterproof football, or a football with a seamless foam-rubber outer layer, can be practical in wet weather. However, pay attention to the difference between water-resistant material and a claim about prolonged use in water. According to Longsail's product information, the outer layer of the footballs mentioned is designed not to absorb water. This is a product claim made by the brand; performance and wear may vary depending on the playing surface.

Checking the material, grip and air pressure

1. Outer layer and grip

Rubber is popular for outdoor basketballs because it can withstand rough surfaces. A textured surface with grooves can help with ball control. In wet weather, however, grip also depends on the condition of the ball, your hands and the playing surface.

For footballs, TPU, synthetic materials and foam rubber are commonly used. A soft outer layer feels comfortable when passing and receiving the ball, while a sturdy construction is better suited to intensive use on grass or artificial turf.

2. Air retention and valve

A ball that regularly loses air is inconvenient and can lead to extra costs. Check the following:

  • whether it uses a butyl or latex bladder;
  • whether the valve has a double construction or extra sealing;
  • whether a pump and needle are included;
  • what air pressure the manufacturer recommends.

According to Longsail's own information, limited air leakage over a period of 48 hours is intended for various models. This is a claim made by the brand and does not guarantee that every ball will retain the same pressure in all conditions.

3. Accessories and storage

A basketball with pump or football with pump is useful when you want to start playing straight away. A carry bag or net keeps the ball from being left loose in the shed and coming into contact with sharp objects. Many models are shipped uninflated. After receiving your ball, first check the valve, the included needle and the condition of the surface.

Store a ball somewhere dry, away from direct sunlight and not next to a radiator for prolonged periods. Clean off mud or sand with a damp cloth. Do not use harsh cleaning products.

Frequently asked questions about sports balls

Which sports ball is suitable for a 5-year-old?

For football, size 3 is usually the obvious choice. For basketball, you can consider size 3 or size 4, depending on hand size and the recommendation on the product page. A smaller ball may be easier to hold.

Do sports balls always come with a pump?

No. According to the product description, some Longsail basketballs and footballs are supplied with a pump, needle and bag. The adidas Tiro Club is supplied uninflated and requires a separate pump. Check this before buying.

How long does an outdoor sports ball last?

Its lifespan depends on the playing surface, frequency of use, air pressure and storage. Tarmac and concrete generally cause more wear than grass or a sports floor. Keep the ball out of strong sunlight, prevent contact with sharp objects and do not inflate it beyond the recommended pressure.
