Choosing Size Guide


Light to Medium Flow
Medium to Low Cervix

  • Lower capacity for a light to medium flow, discharge, and spotting.
  • More comfortable for a medium to low or tilted cervix.
  • The narrower body might be easier to insert for teens, virgins, or new users.

Although the small has a lower capacity – 22ml to the air holes and 29ml to the rim – this size still holds approximately 10% more than the average small size menstrual cup.  That equals to 5 regular absorbency tampons!


High Capacity for Heavy Flow
Medium to High Cervix

  • High capacity for heavy flow and/or clotting.
  • The extra length will be easier to reach for a medium to a high cervix.
  • Extra inner ring for easy opening.
  • Can be worn with a lighter flow to extend wearing time to up to the full 12 hours.

The large size has a capacity of 38ml to the air holes and 47ml to the rim – approximately 30% more than the average large sized menstrual cup and is equal to 9 regular absorbency tampons!
