Read diameter and length together
Diameter, cup length, total length and capacity describe different things. Looking at one number alone can make the decision feel simpler than it is.
Editorial menstrual cup guidance by MonthlyCup
Cup Atlas
A clearer way to compare menstrual cups.
This site turns product data into plain-language guidance: what measurements mean, which questions are worth asking, and where to find current MonthlyCup instructions before you buy or use a cup.
Source-aware, not hype-led.
We use manufacturer-published product details and avoid invented tests, rankings, medical promises or universal-fit claims.
3 modelsMini, Normal and Plus measurements are summarized from MonthlyCup’s published guide.
12 hoursManufacturer guidance says to empty according to flow and no later than 12 hours.
No guaranteesFit is individual; age or childbirth alone is not treated as a size rule here.
Use the data
Measurements are useful when they stay in context.
Cup choice is not a personality quiz. It is a small product decision shaped by dimensions, capacity, flow, comfort preferences, and the instructions supplied with the cup.
Compare flow and routine
The MonthlyCup guide advises comparing measurements with individual flow and preferences. It does not present a single model as guaranteed for everyone.
Follow the supplied instructions
Basic use and care guidance includes washing hands, releasing the seal before removal, boiling as instructed, drying fully, and storing with air circulation.
Verified figures
