The CRL is the measurement between the top of the head to the area above where legs begin and it is done by ultrasound usually up to the 14th week of the pregnancy. Here is the crown rump length chart which helps you analyze your child's growth. This CRL (Crown Rump Length) Chart shows the number of weeks (from 6 weeks to 14 weeks) and the corresponding length of the fetus excluding the limbs and yolk sac.
