How to Measure Your Cervix Height For A Menstrual Cup

There are lots of things that go into finding the best menstrual cup as we discuss in our "Choose A Menstural Cup" article. One of the important factors is your cervix height. 

For many (myself included) measuring cervix height is a new thing. Your cervix can actually move in your vaginal canal through our your monthly cycle with many people finding it lower in the vaginal canal at the start of your period. For this reason it is best to check your cervical height on the first day of your period. This can be a bit messy but you only really need to do it once and then you'll know.  We recommend doing this in the shower for easy clean up.

If you don’t know what your cervix feels like it feels spongey but firm bit of skin inside your vaginal canal. I’ve seen it described as feeling like the end of your nose.

How To Measure Cervix Height

Many find it easiest to check their cervical position in the shower as they are likely to be relaxed.

  1. Wash and dry your hands
  2. Insert one or two fingers into the vaginal opening. The first thing you will feel are your vaginal walls which will feel soft a bit like the inside of your cheeks.
  3. Higher up you will find your cervix. The cervix will feel different, smooth but with a firmness like the tip of your nose.

It really is that simple!

Please be aware that your cervix position can move throughout your menstrual cycle or with sexual aroused so measure at different points in your cycle at roughly the same time each day.

How high is your cervix?

See our guide image above. 

  • If you could insert your full index finger into your vaginal opening before your felt your cervix or you couldn’t reach your cervix this would be classed as a high cervix. For cups for high cervix you can find suitable ones in our cups & high cervix article. A high cervix needs longer cups.
  • If you reached your middle knuckle when you reached your cervix this would be considered an average cervix height and you will most likely find that you can get on with most regular cups.
  • If your finger barely reached the first knuckle on your index finger then you will need a shorter cup suitable for a low cervix and can find the best menstrual cups for you in our cups & low cervix article. Low cervix need shallow cups.

Is it also alright to check your cervix height on the second day of your cycle to find a menstrual cup size, in case I forgot to check on the first day?
