Does baby length indicate height?
The increase in adult weight per relative birth weight category was greatest for infants who were both heavy and long at birth. Conclusions: Birth length is perhaps a better predictor of adult height and weight than birth weight, and should be considered as a possible risk factor for adult morbidity and mortality.

In the first trimester, doctors measure fetal length from crown to rump, or from the top of a baby’s head to the bottom of his bottom. Crown to rump measurements are made using an ultrasound, and are only used early on in pregnancy (until about 14 weeks), while the fetus is still in more of a curled position.

What is the average length of a pregnancy?
About 90% of pregnancy will naturally last between 37 and 42 weeks, and because of this that it is referred to a normal term pregnancy. Naturally about 5% (1 in 20) pregnancy will last less than 37 weeks and 5% (1 in 20) will last more than 42 weeks.
