The average cervix length is 4 to 5 cm, and it is expected to shorten as you get further along into your pregnancy. One study found that at 24 weeks gestation, the average cervix length is 3.5 cm. When cervical length is less than 2.2 cm, women face a 20 percent probability of preterm delivery. Another study found that when the cervical length measures 1.5 cm or less, the risk of spontaneous preterm birth is almost 50 percent.
