Discover the best menstrual cup for you!
If you are exploring this page, it’s likely your first menstrual cup experience has been frustrating, and you are looking for better menstrual cup options.
First off, Thank you! for persevering. There are other options, and we hope to guide you towards your perfect cup on this page. At the bottom of this page, you will find our popular side-by-side photo comparisons of cup brands, making it easy to compare the different options.
At the very end, you also have the option to submit a questionnaire and receive personalized feedback regarding your choice of menstrual cup.
The first brand to be widely available was Diva Cup. Many of the brands following, like Lunette, Lena, Saalt, etc., followed the system established by Diva menstrual cups.
Most of them are designated as no-births and post-birth sizes or labeled as over-age 30-cups, etc. Remember that bodies tend to be more complex than these factors, so it is no wonder that many menstrual cup users do not fit perfectly into these categories.
An ill-fitting menstrual cup can lead to leaking or pain and offer a frustrating, unreliable user experience.
To make it easier to find your MeLuna size, we have included the most common competitor’s brand, Diva, in our lineup here:
We are using Diva cups 1 and 2 in this illustration simply because most other menstrual cup brands that followed modeled their sizing after the Diva cup and are similar or even identical in diameter.
In other words, brands like Saalt, Lunette, and Lena have almost identical sizes in terms of diameter. The Diva sizing will apply to so many!
Is your menstrual cup too long?
If your current diameter seems to work out well, but the cup protrudes or is uncomfortable at the vaginal entrance, you may be a great candidate for a low cervix cup. Learn more about them here.
Generally, we recommend going a size up if you are switching to a shorty. For example, if you are coming from a Diva 2 that’s too long, your best choice may be the Shorty XL, as it is significantly shorter while at the same time being just a tad wider.
Is your menstrual cup diameter too wide or too narrow?
When only 2 or 3 diameters are offered, it takes work to find the match that fits you best, which can be challenging. Insufficient diameter (too narrow) is the most common cause of menstrual cup leaks, while a cup diameter too wide can make it difficult to unfold or be uncomfortable to wear.
Some Tips for Switching Menstrual Cup Brands
If you have worn your menstrual cup of a different brand for quite some time and it generally worked well, we do not recommend going down in size, even if our general recommendations for new cup users suggest it.
For example, if you had less than two vaginal births, the new user suggestion for MeLuna would be size Large. If you have worn the Diva size 2 for several years and want to switch, a MeLuna large would have a slightly smaller diameter than your existing cup.
In that case, a MeLuna XL could be a better choice to avoid leaking due to insufficient diameter, the most common cause of leaking. Our blog post has more info.

Visual Menstrual Cup Comparisons
Many customers who are unhappy with their current cup find it helpful to see it next to a MeLuna.
To make it easier to differentiate, we used all Sapphire blue MeLuna menstrual cups when standard length cups are shown and all Amethyst purple MeLuna menstrual cups when SHORTY MeLuna are shown.
We are organizing the cups in the smallest to largest DIAMETER sizes.
If the competitor's diameter is the same as MeLuna's, we place the competitor's cup first. MeLuna cups come in four sizes (Small, Medium, large, and XL), so you will see four MeLuna cups in each lineup.

What to Expect When Switching Cup Brands
For customers switching from silicone cups to TPE cups, two things are frequently noticed:
1) TPE cups like the MeLuna have a softer snapping open action than silicon cups. This does not mean they're not working. It's simply a different material working a different way. There's no need to panic. Insert the cup as instructed and enjoy a gentler unfolding experience.
2) Unlike silicone cups that always try to regain the round shape they were molded in, TPE cups like MeLuna work by conforming to their surroundings. Since the vagina is shaped more similarly to a compressed hose than a round pipe, it is normal for TPE cups to take on an equally compressed oval or bean shape.
IMPORTANT: None of these factors contribute to leaking. The different materials' properties create a different user experience.
