Which size?

How do I know which size Mooncup to buy?
The Mooncup is available in two sizes: size ‘A’ and size ‘B’. 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.

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’ Mooncup 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.

It's important to buy the right size, as we cannot exchange once the Mooncup is dispatched.

The first time I used my Mooncup, it took a few days to get use to folding and inserting it properly, but I'm so glad I persevered! It's so much more comfortable and cleaner to use than either pads or tampons, so long as you make sure it's sealed properly. No emergency shop dashes; no panic-stocks cluttering up my handbags; and, best of all, no horrible bodily irritations! It's been especially brilliant for me as an avid gym nut, jogger and dancer, and would recommend it to absolutely anyone! I love feeling in control of my body and appearance, and not having to sacrifice doing what I love as a result. I don't know how I've managed to survive so long without a Mooncup. I wish I'd known about this product sooner; it's been an absolute revelation!
