      • well that doesn’t seem right since i have yuuki 1 and its safe capacity is 14ml and the whole capacity is 24ml and in the chart it is 25ml. where did they get that from? yuuki measures are even noted on yuukicup site.

  • Awesome comparison chart, so useful as I’m needing a new cup after having a baby and it allows me to compare measurements with my current cup.
    Just noticed one thing – I think you’ve got the sizes round the wrong way for the mooncup uk – as the A is wider than the B by 3mm. Confusing because most other brands are round the other way!

  • OrganiCup has had an update on sizing!

    Size A –
    Diameter: 40 mm
    Total Height: 65 mm
    Stem: 15 mm
    Capacity: 25 ml

    Size B
    Diameter: 45 mm
    Total Height: 70 mm
    Stem: 15 mm
    Capacity: 30 ml

  • There is a mistake on the diameter of the Monthly cup Size M (or “Normal”).
    These are the measurements of the official website:
    43 mm diameter
    65 mm total length
    55 mm without the stem
    up to 22 ml in capacity

  • i noticed you dont have the cup i use “EVE cup” by Femfulness… its quite short, with a flattened stem and tapered end, and quite firm. . (my whole cervix seems to fill/sit right in the cup—-long thin cervix… is that a thing? AND cervix sits quite low, some times….)

  • Do all cups have the measurement on the side? (if not which dont- i need the measure lines)
    If the measure lines are there, how often are they metric? old?(imperial)… perhaps its just the made in USA ones using the old fashioned measure units?

    thanks in advance

  • i’m assuming length given IS without stem… and there’s a separate column for stem, and it includes stem length 😉

  • I think you should differentiate the firmness of the cup at the top/rim vs. the body of the cup. The two can be very different and both are a consideration!

  • Hello, I’ve been using the Lily Cup One for a while. Now is my third cycle with it and I’ve been stuggling a bit. The only days I could feel the suction everyone is talking about were at the end of my first cycle using it when I had a lighter flow. The quiz suggested the Lunette Cup and it is the same lenght as the one I’m using now. Does that mean that I can continue to struggle to get the hand of it and there is no point in changing?

    My stuggles so far:
    – leaking
    – when inserted feels loose, it doesn’t turn or flip but I can role it with my finger
    Otherwise no discomfort when inserting or removing.

    I would really appreciate your support! Thank you!

  • When you don’t list the cups due to ethical reasons, is one of those reasons political? Not trying to start anything, just wondering since ethic differences covers a wide range of issues.

    • Political reasons haven’t been a consideration. Because cups are an internal device, we do our best to make sure all of the brands we list have been tested to meet safety standards, either by the FDA or a similar governing body in other countries.

  • Hello, I’m living in korea right now and there is a lot of brand that are not listed XD I know it’s probably not interesting for you if the cup are not available worldwide but maybe you could search a bit more about the option present in different area of the globe ~

    I actually just bought my first cup and was trying to use information on here to buy the possible right one but most of the cup listed here are not available to me …

    for information I just bought a cup named ‘withcup” , there are two size from what I could find size S(total lenght 7.1 cm, lenght of the stem 2cm, dia 4.2 cm and capacity of 20ml) size L (7.3cm, stem 2cm, dia 4.6 cm , capacity 30ml)

    apparently it’s made in korea (south XD) But that could help people living in korea and wanting to start using cups ~ thank you for your website ~ it’s still helped me figure out how to choose my cup in hope it will fit XD

  • There seems to be a mistake on the diameter of Organicup A. On the product’s website they state that the diameter of size A is 40 mm while the diameter of size B is 45 mm.

  • The capacities for the XO Flo mini cup is wrong. According to their website’s sizing chart, it holds 31 ml to the air holes (and presumably a little more to the rim, although the website doesn’t give a number). This guide says 25 ml to the air holes (and 31 to the rim).
