What is the normal birth weight range for a newborn?

The normal birth weight range for a newborn is generally considered to be between 2500 to 4000 grams. This range reflects the average weight of healthy newborns at birth and is crucial for assessing the newborn's growth and development as well as identifying potential health concerns.

A weight below 2500 grams is categorized as low birth weight, which can be associated with increased risks for health complications. On the other hand, a weight above 4000 grams falls into the category of high birth weight, which can also carry risks during delivery and for the newborn's immediate health. Therefore, the correct range encompasses the typical weights found in healthy newborns, making the choice that includes 2700 to 4000 grams the most accurate based on common pediatric health standards.

While the other options might present reasonable ranges, they extend beyond the more commonly recognized parameters where signs of concern may arise, thereby influencing the assessment of neonatal health.
