Which size?

The Mooncup and MCUK are available in two sizes:‘A’ and ‘B’. Size A measures 46mm in diameter and 50mm in length. Size B measures 43 mm in diameter and 50mm in length. Both sizes have a pull stem 21mm long, which you can trim to the length that is right for you.

Sizing is based on pelvic floor tone, not menstrual flow, and it’s important to get the sizing right to get the best from your Mooncup or MCUK. Pelvic floor tone will vary according to your age, childbearing history and what sort of exercise you do. Corrective surgery to the vagina will also have implications. Check the guidelines to see which size you need:

Size Table

Size Size A

Because vaginal and pelvic floor tones naturally reduce with age, the size ‘A’ is recommended for women aged 30 or over. The difference between the ‘A’ and the ‘B’ is only small (3mm), but it is crucial!

Size ‘A’ is also recommended for all women who have given birth vaginally, regardless of age.

Size Size A

Designed for young girls and women under the age of 30 who have not given birth vaginally. It may also be suitable for women over the age of 30 who have had corrective surgery to the vagina, or who are advanced in tone-maintaining activities such as yoga, dance or pilates.

Testimonials

I've contemplated buying one of these for years, and now I finally have, I wish I'd bought it years ago. It is absolutely brilliant! I've gone through 3 periods so far and the only leak I've had is when I didn't quite seal it right! It's even been abroad on holiday with me and wasn't a Faff at all. You just get into a routine with it. I'm going camping in a few weeks and even though I'd originally thought about taking tampons with me, I'm not going to bother. It's mooncup all the way from now on with those horrible, uncomfortable tampons nowhere to be seen! Can't say I miss the leaking or the discomfort! Thanks for a fantastic innovation!
