Compare dimensions
Diameter, cup length and total length affect how a model compares on paper. They do not guarantee comfort for every person.
Published measurements
Cup size is a measurement question — not a personality test.
Mini, Normal and Plus are easier to compare when you can see the numbers. The MonthlyCup guide advises comparing measurements alongside individual flow and preferences.

No single rule
Why age or childbirth alone is not enough.
The MonthlyCup guide advises comparing measurements and individual flow and preferences. It also indicates that age or childbirth alone are not a size rule, and no model is guaranteed to fit everyone.
Consider flow
Capacity to the holes is one measurement to compare with your flow and emptying routine. MonthlyCup still states emptying should be according to flow and no later than 12 hours.
Keep preference visible
Some readers prioritize a smaller diameter, others focus on capacity or length. Preference is part of the comparison, not a footnote.
What the MonthlyCup Normal Pink product page states.
The listed Normal model has a 43 mm diameter, 55 mm length without stem, 65 mm length including stem, and 22 ml capacity up to the holes. The manufacturer lists medical-grade silicone and manufacture in Sweden for this product. It is supplied with a fabric storage pouch and an instruction manual.
