The cervix itself is only about 1.5–2.2 inches long, but most people asking “how many inches deep is the cervix?” really mean “how far inside the vagina is the cervix from the opening.”

Quick Scoop

  • From the vaginal opening to the cervix is usually about 3–4 inches when a person is not sexually aroused.
  • There’s a normal range: roughly 2–5 inches from the opening, depending on body size, age, childbirth history, and hormones.
  • The cervix itself (the neck of the uterus) measures around 1.8–2.2 inches in length.
  • During arousal, the vagina lengthens and the cervix moves higher up, so it can feel “deeper” and harder to reach.

So in everyday terms: many people will feel their cervix with a finger at around the second knuckle, but for others it may be noticeably closer or farther.

A bit of storytelling to picture it

Imagine the vaginal canal like a short, flexible tunnel that can stretch and change shape. At the far end is a small “door” with a tiny central opening – that’s the cervix, the gateway to the uterus. For some, that door is closer to the entrance of the tunnel (low cervix, maybe 2–3 inches in), for others it’s farther back (high cervix, closer to 4–5 inches in).

Why the depth can change

  • Menstrual cycle shifts (the cervix can sit higher or lower at different points in the cycle).
  • Pregnancy and childbirth history.
  • Level of sexual arousal (the cervix tends to move up and back).

If you’re asking because of pain with sex, using menstrual cups, or trouble reaching your cervix, it’s always best to talk with a healthcare professional who can check your individual anatomy and give tailored advice.

TL;DR: Most people’s cervix is about 3–4 inches inside the vagina, with a normal range of about 2–5 inches, and the cervix itself is around 2 inches long.
