What size menstrual cup is right for me?

Every body is individual, so the size of menstrual cup you need is completely dependent upon your unique body shape. The questions listed here, therefore, are tailored so that you can easily find out what size of cup you need. You can also take a look at asize guide to be sure. There are a few things we can discuss to make the decision easier, and get you a menstrual cup that will fit! 

Not a one size fits all

Although we offer guidance, it doesn’t mean that our recommendations will always work. Someone could have had a vaginal birth and need the size Mini, and another person who has a heavy flow might find the Size A rather than the Size B to be more comfortable, or vice versa. But, as AllMatters offers a size guarantee, there is no risk of losing your money if you choose the wrong cup!

What if it’s my first time using a cup? 

For first-time users, we find that trying a size Mini or Size A is the safest choice. You can start using the cup as soon as you get your period, but menstrual cups require you to be well-versed with your body.

Determining the best size for beginners

When exploring which size menstrual cup is best for beginners, it's essential to consider comfort and capacity. The Mini and Size A are often ideal choices for those new to menstrual cups. Beginners should remember that while a menstrual cup can hold a significant amount of blood — typically more than tampons — the key to comfort isn't just capacity but fit. 

Capacity concerns and adjustments

Understanding how much blood a menstrual cup holds is crucial for selecting the right size. For instance, if you have a heavier flow, you might lean towards Size A or Size B, which hold more fluid than the Mini. However, capacity shouldn't be the only deciding factor. Comfort and fit are equally important.

Signs your cup might be too big

How do I know if my menstrual cup is too big? This is a common concern among users. A cup that's too large may not unfold properly inside, leading to leaks and discomfort. If you're frequently adjusting your cup or experiencing leaks despite having a correct insertion, it might be an indication that a smaller size is needed. 

Remember, the right fit ensures both comfort and efficiency, so don't hesitate to experiment with different sizes to find your perfect match.
