Toy Age Suitability Calculator

Work out toy age suitability instantly with clear inputs, formula shown and shareable results.

About Toy Age Suitability Calculator

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.

Formulas

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

Worked example

With the default values below, Toy Age Suitability Calculator returns Suitability of Not suitable yet - below the stated age. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
