Model measurements

Size labels are easier with real numbers.

MonthlyCup publishes measurements for Mini, Normal and Plus. This page organizes those documented figures and explains how to read them without turning them into a guaranteed fit formula.

A

How to read diameter.

Diameter is one of the physical measurements you can compare between models. The supplied MonthlyCup guide advises comparing measurements alongside individual flow and preferences.

B

How to read length.

Cup length and total length are not the same in the published figures. Total length includes the stem. MonthlyCup also instructs users to release the seal before removal instead of pulling the stem alone.

Do not reduce size choice to one life detail.

MonthlyCup’s guide says age or childbirth alone are not a size rule. The guide also says no model is guaranteed to fit everyone. A more careful approach is to compare the published measurements, your flow and your personal preferences before deciding.
