Sizing and Selection of Silicone Reusable Menstrual Cup

Most brands have a smaller and a larger size. The smaller size is normally recommended for women under 30 who have not given birth vaginally. The larger size is normally recommended for women over 30 or who have given birth vaginally. The menstrual cups with the smallest size diameter are recommended for teenagers, as well as women who are more physically fit, as those with stronger pelvic floor muscles may find a larger cup uncomfortable. Length also needs to be considered: if a woman's cervix sits particularly low, she may want to use a shorter length cup. Capacity is important to women who have a heavier flow; however, all of the menstrual cups currently available have higher capacity than a regular tampon.
