Size Guide

How do I know which size should I get?

The Aunt Flo Cup comes in two sizes –  S (small) and L (large).

Our S is recommend for users under 25 or for those who have not endured child birth although there are some instances wherein beginners or women who are thinking of transitioning to a sustainable period journey would prefer to start with the small cup and get used to it. It’s worth noting that we find physically fit people are often best suited to the S regardless of age.

Our L is best for those over 25 or for women who have endured childbirth at any age, and for those who feel it’s a bit more roomy up there.

We do understand that finding the best size for you can be a bit of a trial and error and so if you would like to try both of them, you can proceed to this link Special price and get both sets at a special price. 

The diameter of the S is 44mm and the overall length including the toggle is 71mm. It holds 20ml (to the holes).

The diameter of the L is 47mm and the overall length including the toggle is 75mm.  It holds 25ml (to the holes).
