What Size Is Your Cervix

The cervix is the lowest part of the uterus. It’s a small passageway connecting the vagina to the uterine cavity, about 1–1.5 inches or 2.5—3.8cm long (1).

What is the average size of the cervix?

The cervix is usually 2 to 3 cm long (~1 inch) and roughly cylindrical in shape, which changes during pregnancy. The narrow, central cervical canal runs along its entire length, connecting the uterine cavity and the lumen of the vagina.

How do I know my cervix size?

  1. Measure while on your period (the cervix moves throughout your cycle)
  2. Insert a finger and feel for the cervix (feels like the tip of your nose)
  3. Measure the length that fit inside using a ruler for the most accurate results.
