Which cup size to choose?
Perhaps you’ve decided to try a menstrual cup but are not sure which cup size is ideal for you? Here’s the answer.
Cups sizes are indicated by numbers.
Size number 1 is a small cup for young girls and women who have not yet given birth.
Cup number 2 (bigger cup) is designed for any woman who has already given birth, as well as for women
with a regular sex life and women over the age of 28.
The size can be found on the upper edge of each cup (opposite the Yuuki logo) and is marked as either
number 1 or 2.
To get a better idea you can compare the sizes of both cups.
Cup No. 1 (smaller)
cup length including stem: 67 mm (49 mm excluding stem)
cup width (diameter): 41 mm
total volume of cup: 24 ml
safe volume of cup: 14 ml - up to safety ring
cup volume up to air vents: 17.5 ml
Cup No. 2 (larger)
cup length including stem: 75,4 mm (57,4 mm excluding stem)
cup width (diameter): 46 mm
total volume of cup: 37 ml
safe volume of cup: 24 ml - up to safety ring
cup volume up to air vents: 28 ml
Of course, it is not possible to specify the size each woman needs. The figures are approximate and depend
on a range of factors.
If you’re unsure, we recommend buying the bigger cup. If the cup is too big, you can save it for the future
and buy the smaller cup.
Unfortunately, for reasons of hygiene we are unable to exchange a used menstrual cup, as we’re sure you’ll
Our range includes two types of cup - Classic and Soft. We have started selling the Soft cup in response
to customers who found the Classic cup unsuitable.
