Factors To Consider

We would like to preface this guide by stating that all women are different with different physiologies and comfort levels. So though we generally advise women to choose their Suci Cup according to the following guidelines, we do want you to understand this is not a definitive sizing chart. 

Choosing the size of a cup is something we wished was easy and definitive, but at the end of the day, it does require a bit of experimenting. Every woman is different, and just like skincare, bra sizes or disposable pad types, there are many factors that can lead to the most comfortable fit for each of us.  

Choose a size based on the guidelines and, if there is no pain, try it for at least 2 cycles to find if it really suits you.

Length of Vaginal Canal

One of the best ways to know which size cup would best suit you is to measure the length of your vaginal canal during your period. In order for a cup to really work for you, it must be able to fit inside entirely.

You can measure your vaginal canal by locating your cervix during your period. Do this by inserting a clean finger into your vagina until you can feel your cervix which feels a bit like the tip of your nose. Take note on how far your finger goes: until the first or second knuckle or more and measure this. 

You should choose a cup height within this measurement for an optimal fit. If you are not able to feel your cervix, this means you have a high cervix and you can use any size cup without fear of it not fitting entirely.

Therefore, if you:

  • Have a vaginal length within 51mm, choose Suci Cup A
  • Have a vaginal length within 61mm, choose Suci Cup B

Strength of Pelvic Floor Muscles

If checking the length of your cervix is not something you are comfortable with, you can choose the size of your Suci Cup based on the strength of your pelvic floor muscles.

The pelvic floor is a group of muscles that are found at the base of your pelvis or torso. When you relax these muscles, you are able to pass urine, faeces and wind and when you contract them, you are able to hold all of it in until you find a convenient and fitting time and place to release. They are also important for sexual functions and to provide support to the baby during pregnancy. 

The muscle tone of the pelvic floor can be affected by:

  • Age – some research has suggested that the strength of the muscles can decrease as women age. However, this does not mean all women start having : weak vaginas: after they hit 30! There is no such thing as a saggy or loose vaginas! It simply means that there is a higher likelihood that as we age, our pelvic floor muscles become more relaxed and will be able to accommodate a larger sized cup. 
  • Pregnancy – some research has shown that women who have become pregnant and delivered more than once may have more relaxed pelvic muscles and would be able to accommodate a larger sized cup.

Therefore, if you:

  • are 30 years of age 
  • have delivered more than one child, 

we would advise for you to try the Suci Cup in Size B.

If you do not fit the criteria above, you may choose Size A.

Your Period Flow

Another factor to consider when choosing your cup, especially if you are familiar with menstrual cups already is:

  • Whether or not your period flow is heavy. 

If you 

  • are already a menstrual cup user 
  • want the ability to keep the cup in for longer between emptying
  • have heavy flow 
  • have a vaginal canal length within 61mm

you can consider getting the Suci Cup in Size B.

If you do not fit the criteria above, you may choose Size A.
