Work out toy age suitability instantly with clear inputs, formula shown and shareable results.
Suitability requires the child to meet the stated minimum age and, for under-threes, every part to be larger than the 31.7 mm small-parts test cylinder diameter. Age labels exist mostly for choking risk, not skill, which is why a part narrower than 31.7 mm rules a toy out for a child under three regardless of ability.
Age check
suitable on age when child's age in months >= toy minimum age in months
Small parts check
for children under 36 months, any part smaller than 31.7 mm across is a choking hazard
