For your Hello Cup Size Guide, please see below…

Our Hello Disc™ comes in an easy ‘one size fits most’.

It’s worth remembering that we don’t recommend buying your cup based on your flow alone. Instead, our sizing is based on fitness and age.


STEP 1. Use our cervix measurement guide to find out where your cervix sits. We have Hello Cups available for all cervix heights: Low, Average and High.

STEP 2. Take our size quiz to work out which Hello Cup best suits you. 


Our S is our smallest, softest cup. It’s the perfect choice for teenagers, petite users or those who prefer a ‘mini’ tampon.

Our M is our ‘one size fits most’ menstrual cup. We recommend it for users under 35–regardless of whether they have had children or not.

Our L (L for ‘Lovely’) is best for those over 35 who feel their pelvic floor is not what it used to be. It’s worth noting that we find physically fit people are often best suited to the S/M regardless of age.

If you’re uncertain, Hello Double Boxes are a great option to help you find which size works best for you. Many people find they can wear two sizes.

The Hello Disc is another great option as it comes in an easy 'one size fits most' option.
