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 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 35 who feel it’s a bit more roomy up there (possibly thanks to pushing out a small human or two).

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 _____ 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 20mls (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).
