Buying a basketball: how to choose the right ball for indoor and outdoor play

Buying a basketball seems straightforward, until you have to choose between size 5 or size 7, rubber or synthetic leather, and a ball on its own or a complete basketball set. Marketing copy often uses terms such as “all-weather”, “extra grip” or “durable construction”, but they only mean something if you know which specifications are behind them.

The most common buying mistakes come down to three pitfalls:

  • The wrong size: a size 7 basketball is suitable for many adult players, but can feel too large and heavy for children aged around 9 and over.
  • Material that doesn’t suit the playing surface: a soft PU or microfibre covering feels comfortable, but if you’re playing outdoors on tarmac, you also need to consider wear resistance.
  • Missing accessories: some basketballs are supplied deflated. Without a pump or needle, you won’t be able to start playing straight away.

Checking the size, material and playing environment makes buying a basketball much easier.

The key specifications to consider when buying a basketball

1. Choose the right basketball size

The size affects ball control, dribbling and shooting. So check not only the recommended age, but also your club or competition’s requirements.

  • Size 7 basketball: approximately 75 cm in circumference. This is the standard size for adult men and is generally used from around age 13.
  • Size 5 basketball: approximately 70 cm in circumference. This size is intended for young players aged around 9 to 12.
  • Size 4 or smaller: often suitable for younger children, depending on their age, height and playing experience.

A smaller ball is usually easier for children to handle. An oversized ball can make learning to dribble and pass unnecessarily difficult. If you’re looking for a basketball for children, it’s worth checking the size chart on the product page.

2. Consider the material and playing surface

A rubber basketball is a practical choice for a driveway, school playground or other rough surface. Rubber is generally easy to clean and suitable for regular outdoor use. A PU or microfibre leather ball often feels softer and can be a comfortable choice for indoor basketball, but always check whether the product description says it’s suitable for indoor and outdoor use.

An indoor/outdoor basketball is designed for use on different playing surfaces. That doesn’t mean every ball will perform equally well in all conditions. Tarmac and concrete cause more wear than a wooden sports floor. Whenever possible, use the ball for the purpose recommended by the manufacturer.

3. Check the grip, air retention and accessories

Deep grooves can help you hold and control the ball. Also check:

  • whether a pump is included;
  • whether one or more valve needles are included;
  • whether the ball is supplied inflated or deflated;
  • whether the recommended air pressure is specified;
  • whether storage and cleaning instructions are provided.

A basketball with a pump is handy for use at home and on the go. If you’re buying a set, it’s also worth checking exactly what’s included. A basketball set might include a carry bag, pump or hoop, for example, but this varies by product.

Frequently asked questions about buying a basketball

Which basketball is suitable for children?

For children aged around 9 to 12, a size 5 basketball is often a good starting point. Younger children may benefit from a size 4 or size 3 ball. Always check your sports club’s rules and choose a ball the child can hold comfortably.

Can I use the same basketball indoors and outdoors?

You can if the product description explicitly says it’s suitable for indoor and outdoor use. A rubber basketball is a practical choice for outdoor play, while a PU or microfibre leather ball is often chosen for a softer feel. Playing outdoors on tarmac generally causes more wear than playing on an indoor floor.

How long does a basketball last?

Its lifespan depends on how often it’s used, the playing surface, air pressure and storage. Clean the ball with a slightly damp cloth and store it somewhere dry, away from direct sunlight and extreme heat. Check the valve regularly, too, and avoid prolonged use on rough surfaces if the ball isn’t designed for them.
