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.
Visual Menstrual Cup Comparisons
Seeing your current cup side by side with MeLuna sizes can make choosing easier. To help, our comparison visuals use color-coded MeLuna cups. (Of course all models are available in all colors):
- Standard Length MeLuna: Sapphire Blue
- Shorty MeLuna: Amethyst Purple
All cups are arranged from smallest to largest diameter. If a competitor’s cup matches a MeLuna size, you’ll see them side by side.

Thumbs up!
i started having issues with my previous cups due to some pelvic floor changes and thought I would have to stop using menstrual cups altogether… I’m so gladI gave MeLuna a chance! It’s so comfortable and stays in place well.

I got my first cup 10 years ago. I know my body has gone through changes since then, so I headed over to the live chat to express my concerns and got a recommendation. This cup is a better fit and having one with color is nice too.

a cup that fits!
I was a long-time user of a different menstrual cup that I always struggled to get the right fit without feeling it. I took a quiz that suggested I try MeLuna's low cervix cup, and it fit so well, I honestly forgot it was in. I had to keep reminding myself to empty it throughout my period! Super comfy and easy to use. No spillage, either!

Perfect fit
Just got a new one to replace the one I had been using for the last few years. The old one worked so well for me, I replaced it with the exact same cup.

What to Expect When Switching Menstrual Cup Brands
If you're moving from a silicone menstrual cup to a TPE (thermoplastic elastomer) cup like MeLuna, you might notice a few small differences. These changes are normal and completely safe.
1. A Softer, Gentler Unfolding
TPE cups open more gently than silicone cups. You may not feel the same firm “pop open” sensation, and that’s perfectly fine; it’s simply how the flexible TPE material behaves.
✨ Just insert as instructed and enjoy the smooth, comfortable unfolding. No noticeable pop required!
2. Adapts to Your Body’s Shape
While silicone cups tend to hold their original molded shape, TPE cups naturally adjust to your anatomy. The vaginal canal is more like a soft, flexible hose than a rigid tube, and TPE cups conform beautifully to that environment.
Your MeLuna may take on a slightly oval or bean-like shape once inserted, that’s exactly how it’s meant to fit your body.
Important: These differences do not affect performance. Leaks are almost always related to placement or sizing, not the material. TPE simply offers a more adaptable, body-conforming experience.
