Fetal Weight And Length Measurement Chart For You To Keep Track

It is important to keep track of whether your baby is growing normally or not. Your baby’s growth and development need to be normal in order to have a normal childbirth. A baby scan offers to let you know that you are having a normal baby with the help of fetal health scan. Of course, there is an established measurement that is deemed as normal.

Fetal Weight

 

Fetal weight can be measured during the fetal health scan. In this scan, the all-over health and the measurement of the fetus are taken into account. But this scan can be done only from week 16 to week 42. So we will give you a chart of normal fetal weight from week 16 to week 42 to keep track of. Keep in mind that numbers are only averages. It can vary slightly from the given measurement.

Fetal Length

 

Along with the weight, the doctor keeps a record of the fetal length as well. The given below chart is a rough guide of the fetal length from week 16-42. The process of measuring the length of the fetus is to measure it from the crown to the bottom. This is due to the position of your baby where the legs remain curled up against the torso. So it is difficult to measure the length from head to toe.

 

16 weeks     11.6cm
17 weeks     13cm
18 weeks     14.2cm
19 weeks     15.3cm
20 weeks     25.6cm
