Which length would be within the normal full-term AGA range?

• A. 18 Inches
• B. 20 Inches
• C. 23 Inches
• D. 21 Inches

Answer: (D)

For a term newborn, length is expected to fall within about 19 to 21 inches (roughly 48 to 53 cm). Choosing 21 inches fits squarely inside that typical range, so it reflects a normal length for a full-term infant classified as appropriate for gestational age. An 18-inch length would be shorter than expected for term, and 23 inches would be longer than typical for a term newborn. A 20-inch measurement is also within the normal window, but 21 inches is a representative example that clearly lies within the usual range.
