Buying GuideSafetyJune 15, 2026

Choosing the right ball pit balls might seem straightforward — but there are actually several factors to consider if you want a safe, durable, and vibrant play space. Whether you're setting up a commercial indoor playground, a daycare center, or a home ball pit, this guide covers everything you need to know.

1. Size: 55mm vs 70mm vs 80mm

SizeBest ForCoverage per 1000 ballsAge Range
55mmSmall home pits, sensory bins~1.5 m²3+ years
70mmStandard commercial pits, daycare~2.5 m²2+ years
80mmLarge commercial playgrounds, deep pits~3.5 m²1+ years

Recommendation: 70mm is the most popular choice among indoor playgrounds. It's large enough to prevent choking hazards yet small enough for dense coverage. For deep ball pits (60cm+ depth), 80mm provides better float and visual impact. Browse our full product collection →

Frequently Asked Questions

What size ball pit balls should I buy?

55mm suits small home pits and sensory bins for ages 3+, 70mm is the standard choice for commercial ball pits and indoor playgrounds, and 80mm works best for deep pools where you want fewer balls to fill the same volume. ViviBalls supplies all three sizes in Macaron, Candy and Pearl colour collections.

Are ball pit balls safe for toddlers?

Yes, provided they are made from virgin HDPE and certified. ViviBalls balls are BPA-free, non-toxic HDPE with CE, ASTM and EN71 certification. All three sizes are larger than 42mm, so they are not classified as small parts for children under 3.

Which certifications should I look for when importing ball pit balls?

For the US market ask for CPSIA plus ASTM F963 and a Children's Product Certificate (CPC). For the EU ask for EN71-1/2/3 test reports, a Declaration of Conformity and CE marking. ViviBalls supplies the supporting test reports for both markets.

How many ball pit balls do I need?

As a rule of thumb allow 500-800 balls per square metre at a 30cm depth using 70mm balls. See our quantity calculator article for an exact table by pit diameter.
