Lumma Cup is a new line of menstrual cups, from the makers of Lumma Disc. This menstrual cup comes in a staggering ten size models to fit nearly all bodies.

Lumma Cup Features
The firmness is the same for all the Lumma cup sizes and styles – they would be best described as “Average firm.” The cups also feature indentations around the base that help to break the suction during removal. The stems on the Lumma are hollow.
How to Find Your Lumma Cup Size
The sizing system appears complicated at first, but let me break it down for you:

S, M, and H: Sizing by your cervix height.
- S = “short cervix” / “low cervix”
- M = “medium cervix” / “average cervix”
- H = “high cervix” / “tall cervix”
Within these categories of Cervix Heights you have further sizing options.
- By default, S, M, and H sizes are “small” meaning the cup has a narrow diameter designed for those who are under 30, haven’t given birth, or for anyone who feels they should have a smaller diameter.
Lumma Cups with “B” in their size coding have a larger diameter designed for anyone who has a less tone pelvic floor, due to the natural aging process or due to a full term pregnancy.
- B = “over 30 and/or have had a full term pregnancy.”
Lumma Cups additionally adds another sizing attribute, rounder bottomed cups in their “Medium” and “High” cervix cups that give the wearer a higher capacity. Cups that have a + in their sizing code have a higher capacity.
- + = “Heavy Flow” cups.
How to crack the code: A Lumma Cup MB is for someone who has an average height cervix and is over 30/ has had a full term pregnancy and with a light-average flow. An H+ would be for someone with a high cervix, under 30, and has a heavy flow.
Yes it’s a lot to take in at first! It took me some time to understand their sizing code and options but when you know your body well this system is extremely exciting! You can narrow down your needs to the perfect cup for you.
Hopefully this guide will help you find just the right cup for you. PN will have a Lumma Cup review in the future.
I have a high cervix,can heavy flow and a narrow canal. But Silicone and Latex cause too many rashes. Do you think Lumma might ever make their cups in medical grade TPE?
I don’t think that is a likely scenario. I don’t know of any TPE cups on the horizon or out currently that might fit the bill as a high cervix option, unfortunately. The narrow/high cup that exists, JuJu Model 3, is silicone also.
Can u still cut the stems off??
Yes, the stems can still be trimmed even though they’re hollow. The base is solid
I’m 14 and i want to try this cup, do you recommend this cup for a starter teen?
It could be a great starter cup in size. Saalt Teen, Organicup Mini, Hello XS are also good teen cups
Thank you for this chart. I WISH they’d implement it on their site. The shapes that work best for my body are not what they recommend for me in their “quiz” and having a list that doesn’t correspond to ANY photo is so annoying. You are doing the absolute best thing here!
