A mini basketball is a smaller, lighter version of a standard ball designed for compact hoops and casual play. It’s great for tight spaces, younger players, and over-the-door or arcade-style hoops.

• Typical sizes: About 5–7 inches in diameter, including size 1 (around 5 inches), 6-inch balls, and size 3 (about 7 inches).
• Common materials: Rubber or PVC for realistic bounce and durability; foam for quiet, safer indoor play.
• Where it’s used: Mini hoops, indoor games, pool play, and youth practice.

On Walmart.com, you’ll find options labeled for indoor, outdoor, or “silent” play, plus singles and multi-packs. Matching ball size to your hoop helps keep play fun and frustration-free.

Mini basketballs come in a few popular sizes, so it’s smart to match the ball to your hoop and player.

• 5-inch (often called size 1): Common for many over-the-door mini hoops and younger kids.
• 6-inch: A step up for a little more heft and grip, still compact for indoor play.
• 7-inch (size 3): Often used for youth training and some arcade or outdoor mini hoops.

Product pages on Walmart.com typically list the diameter or size number. If you’re unsure, check your hoop’s description for a recommended ball size, or measure the rim and choose a ball that comfortably fits through with room to spare.

For indoor play, look for features that keep things fun and low-impact.

• Material: Foam or “silent” balls help reduce noise and are softer on walls and furniture. Rubber or PVC offers a livelier bounce but can be louder.
• Size match: Confirm the ball size (5", 6", or 7"/size 3) matches your mini hoop.
• Grip: A textured surface can help smaller hands control the ball.
• Use case: If you’re practicing layups and bank shots, a rubber/PVC ball may feel more realistic; for late-night play, foam tends to be quieter.

Filtering for “indoor” options and reading product details can help you find a ball that suits your space and play style.

It depends on the hoop. Many over-the-door mini hoops are designed for 5-inch balls, but some arcade-style or youth rims work better with 6–7-inch (size 3) balls.

• Check your hoop’s listing: Look for a stated compatible ball size (e.g., “5-inch” or “size 1”).
• Measure the rim: If specs aren’t listed, measure the hoop’s inner diameter and choose a ball that passes through with comfortable clearance.
• Match materials: Foam, rubber, and PVC balls of the same size can feel different; pick the one that suits your play.

Confirming compatibility on the product page can help avoid trial-and-error and keep shots swishing instead of rattling.

You’ll find plenty of standalone mini basketballs and accessory bundles on Walmart.com.

• Search by size: Try terms like “mini basketball 5 inch,” “6 inch,” or “size 3 (7 inch)” so it matches your hoop.
• Look for bundles: Some listings include a hand pump and inflation needle; others sell multi-packs of balls.
• Choose material: Foam for quiet indoor play; rubber/PVC for durability and bounce.
• Check product details: Confirm diameter, intended use (indoor/outdoor), and what’s included in the box.

Using category filters (like Kids or Indoor) can help narrow options. Verifying size and material up front makes replacements feel consistent with your current setup.
