I've put together a draft for a "how to find your cup size" guideline. It's based on my experience with my own anatomy and what I've read in this community. Please comment and let me know whether your cup experiences correspond to it!

Guessing your cup size:
1) Reach up into your vagina during your period and find your cervix. (Ideally, do this a couple of times at different points in your period, because some women's cervixes move a lot during their cycles.) If you can easily reach your cervix without bearing down, the Diva will probably be too long for you. If you can't reach your cervix at all, get a cup with a long stem and don't cut off the stem before you try the cup.

2) See how many fingers you can fit in your vagina. If you can't fit three, get one of the smallest cups (small Lunette or Lady Cup). If you can fit three but it's uncomfortable, you might be able to handle a medium-width cup (small Diva, Miacup, Keeper, Mooncup UK) but shouldn't get a large, and you'll probably be better with a small cup if you have small fingers. If you can fit three fingers easily, a large cup might be workable.

What I'm basing this on:
I can reach my cervix fairly easily with my middle finger, and find the Diva slightly long--my cervix actually fits inside the cup, and the bottom is RIGHT at the entrance to my vagina even with the stem cut off. I can fit three fingers in my vagina but find it a bit of a stretch, and the Diva is mostly okay width-wise now (after a year) but felt too wide when I started using it (removal was painful).

I have short fingers with average width-to-height proportion. My ring size (right ring finger) is about 6.25 to 6.5 (M 1/2 to N in British sizes: see converter). I'm 25, no kids, a virgin but *ahem* otherwise physically experienced, used O.B. tampons in regular through super plus sizes from age 10 on. If I get a second cup at some point, it'll probably be the small Lunette--I have a feeling the shorter length and slightly narrower width, but without seriously reduced capacity, would make it the best cup for me.

2 doesn't apply for me at all. I can't fit 3 fingers in, but I use a large Lunette just fine.

It's the same for me, actually. The large Lunette has never been a problem, but three whole fingers? That's a tight fit.

haha, none of those guidelines would work well for me because it all varies greatly on a number of different things

Nope, doesn't apply to me either.

Hmm. So far, it seems I've struck out. Is it just the fingers/width guideline that isn't holding true, or is my Diva/cervix suggestion off as well?

yeah, none of those apply to me either. :-/

You know, if finding guidlines like this is even possible, I think a survey would be the best option. Some possible questions:

What cup do you use? (if you use more than one, pick the one you like best)

When you try to find your cervix during your period, how far in do you have to put a finger?
a. less than an inch
b. 1-2 inches
c. 2-3 inches
d. 3 inches... I can just barely reach it!
e. I can't feel it at all

How many fingers can you fit in your vagina? (this should be with *some* stretching, but not painfully so)
a. none; yikes, it hurts too bad!
b. 1
c. 2
d. 3
e. 4 or more

Any other questions that y'all can think of? Obviously this will require a lot of people who currently use cups to go in the bathroom and check on these things, lol. But I think we have a strong enough membership to do it. I can't make a poll (no paid membership), but I am pretty good with numbers and stuff and am willing to work through the data we collect and see if I can make any sense of it.

Just an idea....

Thanks, this idea seems like a good one. I'm going to be super busy for the next while, though, so I don't know if I'll have time to make the survey.

Hahahah, your basing it on your vagina and your fingers,... unless you have had your hand in other people's vaginas at various times of the month then, your information is flawed,... Just saying.

P.s. none of this applies to me,.. I can't get half a hand (3 fingers) in my vag and I can feel my cervix and am very familiar with it at varioud times of the month and I can use a Diva cup just fine.

Great beginning though and yes, perhaps a poll would help,.. :D

Its a good thought but too bad it doesn't work for a lot of people, but yeah...maybe a poll would be in order, as someone upthread suggested.

My cervix is very low during my period, and I can only fit two fingers easily, but I use the Diva without a problem. But later in my period, my cervix goes up quite high again, and when not on my period, I can't even reach my cervix, so the Diva tends to ride pretty high up there on some days, and a shorter cup might get a little lost some days. The poll idea is great, and it's cool that you're trying to form some guidelines for this (not sure if it will end up being possible, though, as it could be different for everybody.)

Determining the height of the cervix works well but the 1-2-3 finger method really only measures how much one can relax the PC muscle, not the muscle tone of or what will feel comfortable in the vagina itself. The size and strength of the "door" doesn't necessarily have anything to do with the size and strength of the "room" it leads to.

You have taken on a difficult challenge. Picking an appropriately sized cup might prove to be more of an art than a science.
