Size varies a bit at the end. Not all babies are born exactly average. Some are bigger .. some are smaller. Just like normal people. Your due date can be something completely different from how they're measuring.
Think of the measurements as size percentages instead. Baby has a head that's measuring bigger, and would be the 75% for size/gestational age. So for that to be average size .. the baby's head would have to be 2 weeks older than estimated.
Example of a typical U/S: 32 weeks gestaion.
Legs = 32w5d
Arms = 33w4d
Abdomen = 34w1d
Head 32w5d
After that they average everything together and baby would be estimated to be measuring approx 33 weeks. Due date wouldn't change.
