How Your Baby Grows From Week To Week

From early pregnancy, babies grow at different rates, so the following information is only averages. The actual length and weight of your baby may vary greatly. Do not worry if an ultrasound scan shows that your child is much smaller or taller. (Your doctor will tell you if there is any concern about the size of your baby). When fully grown, your baby can weigh only 2500 grams or more than 4500 grams.

If you have a question about our calculations, read our article ""How BabyCenter Calculates Your Pregnancy Week.""

Week 8 through Week 20: Peak to Rump Measurement

Until week 20, peak to rump (crown-rump length, SSL) is measured. Your gynecologist may also call it CRL, derived from the English word crown-rump-length. This is done because the baby's legs are close to the body during the first half of pregnancy and are therefore difficult to measure.
