4 Steps To Choosing A Menstrual Cup

# Step 4: Cup Comparison Charts

If you take a quick look at the charts below, you’ll see:

•  a column labelled (Length/mm)
• a row labelled (Width/mm)
• menstrual cups organized by their length and width

*The lengths of the menstrual cups in the charts are from the rim to the base.The stem length has not been included in this measurement since it can be trimmed to obtain a personalized fit.*

## How To Use The Charts

After completing Steps 2 & 3, you should have a measurement for your available cup space in millimeters.

Using my measurement as an example:

I have 50 mm of available cup space. Go to the first chart and find 50 mm on the column labeled (Length/mm).

After finding 50 mm on the chart, I can then choose a cup  between 40 - 49 mm long.

Remember that 10 millimeters is only 1 centimeter, which is not a drastic difference in length, unless we’re talking about the reverse scenario.

After 50 mm, the menstrual cup can’t go any higher, so if I unknowingly choose a cup that’s 10 mm longer, all of a sudden that extra 1 centimeter starts to feel a whole lot longer.

Visualize the cup rim pressed against your cervix while the base of the cup tries to poke a hole in the seat of your underwear, even after completely removing the stem. Not the most comfortable feeling...

So to be on the safe side, my recommendation is to choose a cup that's 1-10 mm shorter than your cervix height. This will allow you to have space between the cup rim and your cervix, while keeping the base of the cup within easy reach

Once you know your cervix height:

• use the first column labelled (Length/mm) to find your cervix height in the charts below
• See which cups are 1-10 mm shorter than your cervix height
• then click on your cup or cups of choice to be taken to the product page

Example:

My cervix height/available cup space is 50 mm. After finding 50 mm on the chart, I’ll subtract 10 = 40 mm

I can now see which cups fall between 40 - 49 mm on the chart, and click on the cup of my choosing.

Low cervix: you have to be a lot more selective in your cup choice. MeLuna offers the best variety for ladies with very low cervixes.

Medium cervix: any of the cups above can work, simply choose one that is shorter than your cervix height and avoid cups that are longer than your available cup space.

Most of the cups are narrow in width. An extra narrow cup is best for teenagers and virgins. Because MeLuna’s cups are on the shorter side, they offer wider options to help increase the amount of fluid the cup can hold.

If you have a high cervix, the sky is the limit since technically most cups on the market will fit. Your biggest challenge will arise if you pick a cup that's too short. A shorter cup can work it’s way up your vaginal canal, making it difficult to reach the stem, especially if the cup is 15 or more millimeters shorter than your cervix height.

Remember all those “OMG I can’t reach my cup!” stories you may have read, that’s why... the cup was too short. Choose a cup based on the rim to base length as shown in these charts. You should be able to easily reach the base of the cup so you can pinch it to break the seal and remove it.

If your cervix is somewhere between the middle and last knuckle, any of the cups below can work for you. Simply choose one that is 1-10 mm shorter than your cervix height.

## Cup Widths

For your first cup, I’d recommend choosing either a narrow or medium width cup. There really isn’t much difference between the diameters in these cups. It's best to first learn how to easily and comfortably remove the rim of a narrow or medium cup, before venturing into the wider cups.

The exception to this suggestion, would be for women with low cervices (i.e. can touch your cervix after inserting your finger up to the first knuckle). To truly benefit from the 8+ hours of protection you may need a wider cup to increase the holding capacity.
