Start with dimensions
Diameter and length are concrete. Use them to compare models rather than relying only on labels such as small or large.
Model facts
Menstrual cup sizing works better with measurements than myths.
This page summarizes MonthlyCup’s published model measurements in plain English. It does not tell you which model will fit you; no model is guaranteed to fit everyone.
Published MonthlyCup model measurements.
The following figures are attributed to MonthlyCup’s published guide. Capacity is stated up to the holes. Check the current guide before making a purchase decision.
| Model | Diameter | Cup length | Total length | Capacity to holes |
|---|---|---|---|---|
| Mini | 37 mm | 45 mm | 55 mm | 15 ml |
| Normal | 43 mm | 55 mm | 65 mm | 22 ml |
| Plus | 47 mm | 55 mm | 65 mm | 43 ml |
How to think about size without over-simplifying it.
A sizing page can become misleading when it turns personal factors into rigid rules. MonthlyCup’s guide takes a more measured approach: compare measurements, your flow and your preferences.
Consider flow
The guide says to compare individual flow. Capacity can matter for planning, but it is not a guarantee of experience.
Avoid one-factor rules
MonthlyCup’s guide says age or childbirth alone are not a size rule. Personal preference also matters.
