Fetal growth chart

Babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. This is because a baby's legs are curled up against his/her torso during the first half of pregnancy and very hard to measure. After that, babies are measured from head to toe.

Please use this graph for non-serious estimation (e.g. "How big is my baby today?") and don't freak out if your real number is different. These numbers are just averages. Babies grow at different rates, so your baby's numbers may vary substantially. If you have any concern, please talk to your doctor. I am just a doctor of philosophy, not a real doctor.
