Size Guide

Size guide

From our experience, age and childbirth are not relevant factors. We have clients who have had up to three children by natural birth, who are over 40 years of age, and the BLOOM´s short size works perfectly for them. There are also 25-year-old  women, without children, who need the tall size because of their abundant flow. Our recommendation is to choose your size mainly according to your flow.


Diameter: 1.7 in. (4.2 cm)

Height: 2.4 in. (6 cm)

Capacity:  0.7 fl ounces (20 ml)

Color: Blue

We designed a smaller cup than those usually available in the market, which is perfect for women with normal flow and beginners. Its capacity allows many women to wear it for up to 12 hours. A woman with normal flow bleeds approximately 40 ml during each menstruation cycle.

The short Bloom cup is shorter, so it is easier to insert and to remove. It’s so comfortable you won’t even feel it.



Diameter: 1.8 in. (4.6 cm)

Height: 2.8 in. (7 cm)

Capacity: 1.2 fl ounces (35 ml)

Color: Transparent

If you have very strong flow days, the regular size can fill up too quickly. If this is your case we recommend the tall size, as it has 40% more capacity than the short one. It is also recommended for night time, as some women tend to have heavier flow while sleeping.

The tall Bloom cup diameter and height is longer so it might take a little more practice to learn how to wear it.
