How to Choose a Menstrual Cup That Fits Your Body - Size Guide and Chart
Choosing a menstrual cup that fits your anatomy is key to avoiding leaks, insertion difficulties, and even discomfort caused by the wrong size or a cup that’s too firm.
Criteria for Choosing the Right Menstrual Cup
Based on Your Anatomy
The most important factor is having a cup that’s the right size to prevent slipping and leaks.
Your size will depend largely on your anatomy.
Here’s a general guide:
- Teenagers or Virgins ➡️ Very small size, specially designed for teens.
- Under 25 years old without vaginal birth ➡️ Small size (Size S or Size 1, depending on the brand).
- Over 25 years old or after vaginal birth ➡️ Large size (Size L or Size 2, depending on the brand).
Based on Your Menstrual Flow
Depending on whether you have a light, medium, or heavy flow, your menstrual cup size will also vary.
If you’re unsure about your flow, you can check out our flow calculator in this article (click on the link).
Here’s a general guide:
- Light to Medium Flow ➡️ Small cup (Size S or Size 1)
- Medium to Heavy Flow ➡️ Large cup (Size L or Size 2)
- Heavy to Very Heavy (Hemorrhagic) Flow ➡️ A menstrual disc may be a better option.
Based on Your Cervix Height
Menstrual cups aren’t always the best choice if you have a low cervix.
They may not position correctly, leading to leaks and discomfort.
If you have a low cervix, we recommend:
- ➡️ Using a smaller cup, preferably without a stem.
- ➡️ Or switching to a menstrual disc, which sits higher and adapts better.
Based on Your Physical Activity
If you’re very active or have a strong pelvic floor (perineal muscles), a standard cup might shift during movement and cause leaks.
In that case, we recommend choosing a firmer menstrual cup, which will stay in place better during sports or intense activities.
Cup&Co Menstrual Cup Size Guide
Cup&Co menstrual cups are available in two sizes:
- Size S: Recommended for those under 25 or with a strong pelvic floor.
- Size L: Recommended for those over 25 or who have given birth vaginally.
Our menstrual cups are made from soft, flexible silicone, making them extremely comfortable to wear.
They are ideal for managing light to heavy flows.
Common Questions About Choosing the Right Menstrual Cup Size
Which Size Should I Choose with the Cup&Co Applicator?
Both of our cup sizes are compatible with the Cup&Co menstrual cup applicator.
You can even use it with other brands of menstrual cups and discs!
If you find it difficult to insert the cup with the applicator, you can always use a little water-based lubricant to make it easier.

Can I Change My Menstrual Cup Size for Free?
Usually, no ! Most brands require you to buy a new cup if you need a different size.
But at Cup&Co, it’s different!
If you purchased your menstrual cup within the last 90 days, you can contact our team by email and request a free size exchange.
What Should I Do If I Still Have Leaks Despite Using the Right Size?
If you’re still experiencing leaks even with the correct cup size, there could be other reasons: poor positioning, a low cervix, blocked suction holes, and more.

Does My Cup Size Change Over Time?
Yes, it can!
A cup that fit you perfectly a few years ago might not fit anymore.
Major body changes, like after giving birth, can affect the way your menstrual cup fits.
In that case, you might need a different size or consider switching to a menstrual disc, which works similarly but adapts differently to your body.
