Cervical dilation - interactive tool

Click and drag the slider bar to view cervical dilation.

If you have previously delivered a child, your cervix looks slot-shaped at 0 centimeters, not round.

During early labor your cervix dilates from 1 to 5 centimeters. Mild contractions, about 60 to 90 seconds in length, occur generally every 15 to 20 minutes.

You've entered the active stage of labor, which means your cervix is dilating from 5 to 8 centimeters, contractions have grown stronger and more insistent. They are occurring once every 3 minutes or so, and last for about 45 seconds.

Near the active phase of labor you arrive at the transition phase; your cervix dilates from 8 to 10 centimeters.

At 10 centimeters, your cervix is fully dilated and you are ready to start pushing with every contraction.
