Average Height for 14-Month-Old Babies: What's Normal?

The average length of a 14 month baby is between 28 and 31 inches (71.1 and 78.7 centimetres).

At this age, most boys are between 28.3 and 31.1 inches (72.0 and 79.0 centimetres) in length, while most girls are between 27.6 and 30.3 inches (70.1 and 77.0 centimetres) in length.

However, some infants may be longer or shorter than average, as each infant grows at their own unique pace. If you are concerned about your baby's growth, you should talk to your baby's doctor.
