What is the approximate height of the average 4-year-old child?

• A. 0.75 m
• B. 1.0 m
• C. 1.2 m
• D. 1.5 m

Answer: (B)

Four-year-olds are growing steadily, but not as quickly as in the early years. The typical height at this age is about 102 cm, which is just a bit over one meter tall. Saying roughly 1.0 m matches this common average, since 1 meter equals 100 cm and 102 cm is very close to that. In other words, many four-year-olds are around 40 inches tall, or about 1.02 m, so 1.0 m is the closest approximation. The other heights are noticeably shorter or taller than the usual range for a 4-year-old.
