How do you know the right cup size for you?
Menstrual cups are available in two sizes: small (size 1 or A) and large (size 2 or B). Some brands offer a wider range of sizes, including options for teens and those with a low cervix. Generally, the size refers to the cup’s width rather than its liquid capacity.
Several factors are important when selecting the right menstrual cup size:
- Menstrual Flow: Lighter flows usually require smaller cups, while heavier flows need larger ones.
- Cervix Height: Measure your cervix height by inserting a finger into the vagina to find the cervix. A high cervix requires a longer cup, while a low cervix needs a shorter cup.
- Cup Capacity: Small cups hold 25 millilitres, while larger ones hold about 30 millilitres. Capacity matters for those with heavy flows.
- Cup Length and Diameter: The cup should fit comfortably inside the vaginal canal. Diameter size depends on factors like age and childbirth history.
- Pregnancy: Pregnancy and childbirth can affect pelvic floor muscles, influencing cup size. Smaller cups are recommended for those without childbirth history, and larger ones for those who have given birth.
- Age & Fitness: Smaller sizes are usually for those under 30, while larger sizes are for those over 30. Some brands offer sizes specifically for teens. Active individuals with strong pelvic floor muscles might prefer smaller sizes.
How do you know if the cup fits you well?
Menstrual cup sizes are not standardised across brands. A comparison found that diameters for small sizes range from 39 mm to almost 49 mm across different brands. Typically, small sizes are for people under 30 without a childbirth or pregnancy history, while larger sizes are for those over 30 or with such a history. Some manufacturers also base size on menstrual flow heaviness. Finding the right fit may require trying a few different brands. Most brands offer detailed size guides based on lifestyle and personal factors.
The right size allows for easy insertion and removal and feels comfortable once in place. If the cup is too small, it might leak and be hard to remove. If it is too large, it could cause discomfort.
