Finding the right menstrual cup can take some trial and error. The good news is that you can avoid that wasted time and money by narrowing down your choices based on a few personal factors with the help of some unique menstrual cup comparison tools we’ve created for you!
Menstrual cup manufacturers tell you to buy a smaller size cup if you’re under 30 and have never given birth vaginally. This is based on the belief that if a person is under the age of 30, they may not have had any pregnancies or children, and/or have stronger pelvic floor muscles (PFM).
If you’re older than 30 or have delivered a baby via the vaginal canal (i.e. not through a cesarean section), then they say to get the larger size. This is because of the assumption that those who are over 30 are more likely to have a weakened PFM and/or have had pregnancies or children.
However, an often overlooked factor that can make a big difference in the comfort and effectiveness of a menstrual cup is the position of your cervix – that is, how high or low it is in your body. This varies from person to person and moves throughout your cycle.
What’s a Cervix?
The cervix is the lowest part of the uterus. It’s sometimes referred to as the neck of the uterus, similar to the neck of a bottle. It is tubular in shape and is the passage between the vaginal canal to the uterine cavity.
While the uterus cannot be seen, the cervix can be seen and felt from inside the vagina.
During your period, the endometrium (mucous lining) is shed from the uterine walls and menstrual blood flows out of the cervix.
How to Locate Your Cervix?
- Personal Lubricant specifically made for use inside of the vagina, if needed.
- Very low to Low: If your finger only goes in an inch or so before it comes into contact with the cervix, it is considered low. Tip: You can measure this at approximately the first knuckle or knuckle line closest to your fingertip.
- Medium or Average: If your cervix is easy to reach but not especially low, it is considered medium or average height. Tip: You can measure this at approximately the middle knuckle on your finger.
- High to very heavy: If you can insert your complete finger before locating the cervix or can’t reach it at all, you have a high or very high cervix.
You cervix can move during your period. As mentioned, the cervix may be hard to reach or completely out of reach depending on where you are in your cycle. If your cervix moves drastically, you may want to purchase a two-pack of menstrual cups that offer both a small and a large-sized menstrual cup. This will allow you to use whichever cup is more comfortable and/or easier to reach for you when your cervix is at its different heights.
Which Menstrual Cup Goes with Which Type of Cervix?
Let us Help you Choose a Menstrual Cup!
If your cervix is located at average height (middle knuckle), any standard large-sized menstrual cup may be comfortable for you. However, if your cervix is on the lower or higher side, it pays to check the length measurements to find a cup that will be more comfortable or easier to reach for you.
The cup’s length measurement is particularly important for finding the right cup for your cervical height. We provide a very handy comparison tool that sorts the many menstrual cup brands from large to small. This allows you to select your preferred length, which is heaven for the detail-oriented shoppers among you!
1. Very Low Cervix Menstrual Cups
If you have a very low cervix, we suggest trying a menstrual cup that’s shorter in length because if the cup is too long, it may not fit comfortably during use.
2. Medium to Low Cervix Menstrual Cups
If you have a medium to low cervix, you can use the small size of almost any brand. You can also look into cups that were designed to be shorter than the “average” small-sized cup, often indicated by labels such as teen, mini, shorty, or low cervix.
A bell-shaped cup might be more comfortable for you because the base of the cup is rounded off. This makes it a bit shorter and it doesn’t have the pointed base like V-shaped cups do, which may protrude out of the vaginal opening.
Furthermore, a bell-shaped cup with a flared rim tends to ride up and sit higher in the vaginal fornix. Again, this keeps the base of the cup away from the vaginal opening.
3. Medium to High Cervix Menstrual Cups
If you have a medium to high cervix, using a cup with more length might be easier for you to reach when the time comes to remove and empty it. It may be the larger size of a specific brand or a cup that is V-shaped. A V-shaped cup normally has more length, even in the smaller size. This will allow you to reach your cup with less difficulties.
4. Very High Cervix Menstrual Cups
If you have a high cervix, we suggest looking into menstrual cups that are longer in length. If the cup is too short, it’s not going to be as easy for you to remove and empty it.
Features to Consider
Although the cup’s length measurement is particularly important, here are some other features worth taking into consideration.
- Stem length – Because most of the cup stems can be trimmed, it is best to check the cup’s total length with and without the stem to find the best fit.
- Cup diameter – Although the vagina can expand up to 200 times is normal size, some people may find a narrower cup more comfortable to wear. These may include (but are not limited to) teens, new users, and those with no experience inserting items such as tampons.
- Cup Softness/Firmness – It may help to compare the softness/firmness of each cup model. This will give you a simple at-a-glance view of the essential features of every cup.

No single menstrual cup is going to work for every person! You can, however, increase your chances of finding the perfect cup if you take the time to check your cervical height. We wish you luck and hope this website is a valuable tool in your search!
