Dimensions
Look at diameter, cup length and total length. The MonthlyCup guide lists Mini, Normal and Plus with different measurements, so the comparison should be specific rather than size-name based.
Transparent decision support by MonthlyCup
The best menstrual cup is a match, not a trophy.
This site does not publish a fake “winner” list. It helps you compare menstrual cups by criteria that can actually be checked: dimensions, capacity to the holes, material information, supplied instructions and the routines you are willing to follow.

How to compare
Start with your own constraints, then read the specs.
A useful menstrual cup comparison begins with personal requirements: capacity preference, comfort around diameter and length, how often you can empty it, and how comfortable you feel following the cleaning instructions. Only after that do product dimensions become meaningful.
Capacity
Compare capacity to the holes, not vague labels such as “light” or “heavy.” MonthlyCup lists 15 ml for Mini, 22 ml for Normal and 43 ml for Plus.
Instructions
Include real-life care: washing hands, emptying according to flow, releasing the seal before removal and following boiling and storage instructions.
What this site means by “best”
Best means best-aligned with stated criteria.
For this domain, “best” does not mean independently tested, medically recommended or guaranteed to fit. It means a cup can be considered more relevant when its documented features line up with what you are looking for.
- If you want a smaller listed diameter, compare the Mini measurement first.
- If you are comparing a mid-size option, look at the Normal dimensions and 22 ml capacity to the holes.
- If capacity is a leading criterion, compare the Plus model’s listed 43 ml capacity to the holes against its larger diameter.
- If you are unsure, use the MonthlyCup guide and support resources before deciding.

Can age or childbirth decide menstrual cup size?
