Buying a basketball seems simple, until you have to choose between size 5 and size 7, rubber or PU, indoor or outdoor use, and whether or not you need a pump. Many balls look the same in photos, but can differ in how they play and how they need to be cared for.
When comparing options, look out for these three common pitfalls:
The official basketball size depends on age, competition and hand size. Use this table as a starting point:
| Size | Circumference | Typical use | |---|---:|---| | Size 3 | approximately 57 cm | Young children and learning basic ball skills | | Size 4 | approximately 65 cm | Young players, often around 5 to 8 years old | | Size 5 | approximately 70 cm | Young players and juniors, often around 9 to 12 years old | | Size 7 | approximately 75 cm | Adults and players aged around 13 and over |
Age recommendations don’t replace the rules of a club or competition, so check the requirements set by the coach or governing body too. A size 5 basketball may be suitable for a child’s training, while a particular youth competition may require a different size.
For children around 5 to 8 years old, a size 4 basketball often feels more comfortable to hold. A youth basketball should be easy to handle above all: children should be able to dribble, pass and shoot without constantly having to adjust the ball with both hands.
A rubber basketball is a practical choice for tarmac, concrete, a driveway or a park court. The material is generally more hard-wearing on rough surfaces and easy to clean. A textured surface with grooves and dimples can help with control, particularly when the ball gets damp.
Check that the ball is designed for extended use on rough surfaces. Even a durable basketball will wear out faster if you use it every day on coarse tarmac. Avoid storing it in direct sunlight or extreme heat for long periods too.
An indoor-outdoor basketball offers flexibility if you switch between a sports hall and an outdoor court. PU, composite leather and microfibre leather often feel softer than standard rubber. The product description should clearly state which surfaces the ball is designed for.
Don’t automatically use a ball with a softer cover outdoors only. Check the surface specifications and follow the manufacturer’s recommendations. Claims about moisture absorption, grip or improved bounce come from the brand’s product information and shouldn’t be treated as an independent performance guarantee.
Some models are described by the manufacturer as a water-resistant basketball or as having a surface suitable for wet conditions. According to the product descriptions for Longsail models, some rubber versions are water-resistant and designed for use on outdoor courts and by the pool, among other places. This doesn’t mean you should leave the ball under water for long periods.
Wipe a wet ball with a damp cloth and let it dry before putting it away. Check the valve area too, as dirt and moisture around the valve can make it harder to inflate.
Size and circumference
Don’t just look for “full size” in the title. Check the stated size in inches or centimetres. A size 7 basketball is around 75 cm in circumference; a size 5 is around 70 cm.
Outer cover and grip
A textured surface, deep channels and a butyl bladder are useful product details. They tell you more than the word “professional” on its own. For outdoor use, hard-wearing rubber and a scuff-resistant finish are practical features to look for.
Air retention and delivery
Some models are delivered deflated. Check whether a basketball with pump, needles and possibly a carry bag are included. The product descriptions for several Longsail basketballs say they come with a hand pump, two needles and a carry bag. The stated 48-hour air retention is a claim from Longsail’s product information and applies under the conditions specified there; check the current product page for details.
Care and storage
Use a suitable pump needle and don’t force it into the valve. The product descriptions recommend cleaning the ball with a damp cloth and storing it in a cool, dry place, away from prolonged heat and direct sunlight.
Why it suits this player: This size 5 ball is aimed at young players and recreational use. The included pump, needles and carry bag mean you’ll need to buy fewer extras to get started.
The product information gives an approximate circumference of 70 cm, identifies rubber as the outer material and states that the ball is delivered deflated with a pump. This makes its size and intended use clearer than a general “full size” label.
Size 5, rubber outer cover, textured surface, and accessories for inflation and carrying.
Why it suits this player: This size 7 ball is designed for adult players who value a softer cover and want to play indoors and outdoors.
The product page specifies the material, size and indoor-outdoor use. Do check which cover applies to the version you choose.
Size 7, PU, microfibre or rubber option depending on the version, and deep channels for ball control.
Why it suits this player: This size 7 ball is designed for adults and more frequent recreational play on different surfaces, including outdoor courts.
The description specifies a rubber outer cover that is water-resistant and scuff-resistant. This makes it better suited to rough outdoor use than a court ball with no stated surface details.
Size 7, rubber surface, deep grooves, pump, needles and carry bag, according to the product description.
We’ve put together a complete, up-to-date list of products that meet these strict selection criteria and the applicable European safety regulations.
Always follow the pressure specified on the ball, packaging or product page. Some models list around 7 to 9 psi. Inflate it in small steps, then check the bounce. A ball that’s too hard may feel less comfortable, while one that’s too soft may bounce unevenly.
That depends on the material, playing surface, how often it’s used and how it’s stored. A rubber outdoor basketball can handle rougher use, but tarmac will still cause wear. Clean the ball after use, avoid prolonged exposure to heat, and check the valve and shape regularly.
Yes, especially if you want to start playing straight away or don’t already have a pump and needle. Check that the set really does include a pump, needles and a carry bag. Accessories vary between models, so don’t rely on the product photo alone.
