Menstrual Disc Size FAQ

Which size menstrual disc should I pick? Disc sizing is determined by your cervix height. Not sure where your cervix is located? Watch your  How to Measure Your Cervix  guide.

One Size Fits Most | Regular sizes will fit almost everyone with the exception of people with a low cervix. If you have a high cervix you can wear a One Size menstrual disc but consider one with a removal loop or tail.

Medium | Small | Short sizes are meant for lower than average or very low cervix heights. Sizes Small or Short are very small diameter options and should only be used if you have a low cervix. 

Consider taking the  Period Nirvana Quiz  when choosing your menstrual disc to be matched with the style and size most likely to work for you.

Menstrual Cup Size FAQ

Menstrual cup sizing refers only to the cup's rim diameter, and to pick the size best for you the determining factors are based on your age and pregnancy history (primarily.) Other fit factors include your cervix height and the shape/firmness of the cup. It can be tough to find the perfect fit on your first try; let us take the guesswork out of the process by taking our menstrual cup quiz.

Teen | Mini | 0 | XS sizes are best for first time users, and geared toward teens. These have the smallest diameter.

Small | Medium | A | 1 sizes are best for first time users who are under 30 and haven't had a full term pregnancy. This is a general guideline and not a rule - exceptions to consider would be if you are very active or have a hypertonic pelvic floor. These sizes have a smaller diameter.

Large | Regular | B | 2 sizes are best for users who are over 30 and/or anyone who has had a full term pregnancy. These sizes have a larger diameter to stay in place when pelvic floor muscle tone is more lax. 

Other factors to consider for cup sizing include the length (corresponding to your cervix height), shape, and firmness. We suggest taking the Period Nirvana Quiz for help selecting the right size/shape/firmness for your unique anatomy.
