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 when you find the right one, and there are better options. 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 — like Lunette, Lena, and Saalt — adopted similar sizing systems, often based on age or childbirth history (e.g., “for under 30/no births” or “for over 30/post-birth”).

But here’s the thing:
Your body is more unique than a simple label. These generalized size categories don’t work for everyone, which is why so many users experience leaks or discomfort with mainstream brands.


MeLuna vs. Diva: Size Comparison

To help you better understand how MeLuna fits compared to popular cups, we’ve included visual side-by-side diameter comparisons — including Diva Cup sizes 1 and 2, which many other brands mimic in sizing.

Fun fact: 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 still help.


Does Your Cup Feel Too Long?

If the diameter is fine, but the cup protrudes or causes discomfort near the vaginal opening, you might benefit from a low cervix (Shorty) cup.

Quick Tip:

When switching to a Shorty, we usually recommend going one size up to maintain capacity.
Example: If you’re using a Diva 2 that feels too long, a MeLuna Shorty XL could be the perfect switch — shorter but slightly wider.


Too Narrow? Too Wide? Why Diameter Matters

Menstrual cups with only 2–3 size options can be limiting.

  • Too narrow = leaks
  • Too wide = trouble unfolding or discomfort

MeLuna offers four diameter sizes for a more customized fit: Small, Medium, Large, and XL — plus Shorty versions for low cervix users.


Switching from Another Brand? Here’s What to Know

If you've used a different cup successfully for a while, don’t automatically size down based on general guides for new users.

Example:
MeLuna’s general recommendation for someone with fewer than two vaginal births is a Large.
But if you’ve been using a Diva 2 (which is larger), switching to a MeLuna XL might make more sense to avoid leaks due to a smaller diameter.


Comparación visual de copas menstruales

Many customers find it helpful to see their current cup side-by-side with MeLuna cups.
To make comparison easier we have 'color-coded' the MeLuna cups:

  • Standard length MeLuna = Sapphire Blue
  • Shorty MeLuna = Amethyst Purple

🌀 Cups are arranged from smallest to largest diameter.
If a competitor’s cup shares a diameter with a MeLuna, we show it first in the lineup.

What to Expect When Switching Menstrual Cup Brands

If you're switching from a silicone cup to a TPE (thermoplastic elastomer) cup like MeLuna, you may notice a couple of key differences. Don’t worry — these changes are totally normal and nothing to be concerned about:

1. A Softer, Gentler Unfolding

TPE cups have a softer "pop open" action compared to silicone cups. This doesn't mean the cup isn’t working — it’s just how the TPE material behaves.

✨ Just insert as instructed and enjoy the more gentle unfolding. No noticable “pop” needed!

2. Adapts to Your Body’s Shape

While silicone cups tend to hold their perfectly round molded shape, TPE cups conform to their environment.

Because the vaginal canal is more like a soft, compressed hose than a rigid tube, your MeLuna may take on an oval or bean-like shape once inserted — and that’s exactly what it’s designed to do.

Important: These differences do not affect the cup’s performance. Leaks aren’t caused by the material — they’re usually related to sizing or placement. TPE simply offers a more adaptable, body-conforming experience.
