At a Glance Menstrual Cup Selection Guide – Find the Best Cup!

Finding the best menstrual cup for you to start with or to switch to can be hard. There are so many cups. I often receive private messages and e-mails asking for help picking a first cup or switching to a better-suited cup for your body.

I wanted to put something together that’s easy to look at and can be changed easily as new menstrual cups are released. With the popularity increasing…it seems like new cups are constantly coming out!

Here’s an easy to follow guide to find a cup that may be great for you!

Disclosure: You may follow all of the suggestions here and wind up with the worst menstrual cup for your body ever. Keep in mind that these are guidelines. You may be someone under 30 with a super strong pelvic floor who would find that a firm small menstrual cup is best for you and have the best fit with a soft larger cup.

Menstrual cups are a personalized need and I firmly believe that you need to try one to see what’s right for you. Only when you try a cup will you know if it’s too soft, too short, too firm, too long or perhaps not even the right capacity.

Find cups by firmness, length and see how much they hold under each need/category for a cup suggestion!

Let’s get started!

While cups typically come in two sizes, small and large or model 1 and model 2…lengths vary greatly. I suggest figuring out your cervix height before picking out a cup. However, chances are that you know if you have a low cervix. You would have felt it inserting a tampon, with some sort of penetration or figuring out your cervix height on your own or at a GYN appointment.

 

*This is a work in progress, I’m looking for feedback to continue!

 

A note about length – For the purposes of this article, I’m considering:

High cervix cups 2.6″(66.04 mm) and above with stem.

Medium/Average Cervix height cups up to 2.6″ – 2.2″ (66.03 mm – 55.88) with stem. 

Low Cervix cups 2.1″ (53.34 mm) and below with stem (if the cup has one)

Also, keep in mind…if you are willing to go stemless aka cut the stem off a high cervix cup can turn into a great medium and possibly even a low cervix cup based on cup body length!
