Find the Best Menstrual Cup for Your Body
Struggling to find the right menstrual cup? You’re not alone, and you’re in the right place.
Whether your first experience with a menstrual cup was frustrating or you’re just not quite satisfied, we’re here to help guide you to a better fit.
First of All: Thank You!
We appreciate you sticking with it. Menstrual cups can be life-changing once you find the right one. This page is designed to help you discover your ideal fit with visual comparisons and personalized guidance.
Why So Many Cups Feel the Same (and Why That Might Not Work for You)
The first widely available menstrual cup was the Diva Cup. Many brands that followed, such as Lunette, Lena, and Saalt, adopted similar sizing systems based on age or childbirth history (for example, “under 30/no births” or “over 30/post-birth”).
Your body is more unique than a simple label. These general size categories don’t work for everyone, which is why many users experience leaks or discomfort with mainstream brands.
MeLuna vs. Diva: Size Comparison
To help you understand how MeLuna fits compared to other cups, we’ve included visual side-by-side diameter comparisons, including Diva Cup sizes 1 and 2, which many brands mimic in sizing.
Menstrual cup diameter comparison: Diva Cup vs MeLuna
“Brands like Lunette, Lena, and Saalt are often nearly identical in diameter to the Diva Cup, so if you’ve tried one, this comparison can help you find your MeLuna match.”
Does Your Cup Feel Too Long?
If your cup’s diameter feels fine but it pokes or feels uncomfortable near the vaginal opening, a low cervix (Shorty) cup could be the answer.
Fit tip: When switching to a Shorty, size up to maintain capacity.
Example: If your Diva 2 feels too long, try MeLuna Shorty XL. If Diva 2 also felt too wide, try Shorty Large.
Too Narrow? Too Wide? Why Diameter Matters
Menstrual cups with only two or three size options can be limiting. MeLuna offers four diameters: Small, Medium, Large, and XL, plus Shorty versions for low cervix users, giving you a more precise and comfortable fit.
- Too narrow: May cause leaks.
- Too wide: May be difficult to unfold or feel uncomfortable.
Switching from Another Brand? Here’s What to Know
If you’ve used another brand successfully, don’t automatically size down based on general new-user guides. For example, MeLuna’s general suggestion for someone with fewer than two vaginal births is a Large, but if you used a Diva 2, a MeLuna XL may be a better match to maintain a proper seal.
Suggested MeLuna sizes based on the common cup issues with Diva Cups, also considering your flow: light, average or heavy.
“The Diva Cup stands out because it’s much taller than most cups, even in the teen size. We’ve created a separate menstrual cup problem and solution chart for cups with a more standard height, such as the Saalt Cup. If you’re using another brand that offers two sizes, its dimensions are likely similar to the Saalt Small and Saalt Regular, so the solutions in the chart below should fit your cup as well.”
