Some SIZING GUIDELINES
SizeCharts
sizecharts

Scroll down if you want to jump to the charts.

Don't pick a brand or a size first.  Go by actual dimensions.

EVERY brand says that their Small is for younger users who have not had children that and their Large is for those over a certain age and/or have given birth.  But what they are called doesn't fall within any range of physical sizes.  And of course, every company is going to tell you that their cup will fit you better than their competitors'.

LENGTH is probably your most important measurement.  If you pick a cup that is too long, it will probably shift, leak, feel like it's poking out and be uncomfortable.  If you pick a cup that is too short, your cervix might fill it, leaving very little room for flow and/or you might have a hard time reaching it for removal.

Next period, reach in to feel how long your vagina is.
    If you can reach the end (not necessarily your cervix) easily, it's on the short side.
    If you have to reach really deep or still can't reach it, it's long.
    If it's in between, aim for a medium length cup.

If you're not sure about length, logic says that picking one that's "medium" will have a better chance of fitting than one from either end of the length spectrum.

WIDTH is measured at the rim.
    If you are young and/or new to inserting things into your vagina, you will probably want a narrow to medium width cup.
    If you are comfortable with insertion and/or older and/or have had children, a medium to wide cup will probably suit you.

Once you have an idea of length and width preferences, use the size charts to eliminate the ones you don't think will fit.  And then select the one that calls to you from the ones that remain.

It's not an exact science but getting into the right ball park will increase your chances of success greatly.

The SHAPE of the cup probably has a greater influence than rim width on how "big" or "small" a cup feels so also compare photos of those that fall into your fitment parameters.  A cup's STIFFNESS also plays a role.

Nearly all cups are made of medical grade silicone.  Exceptions are the Keeper, which is made of latex rubber and the MeLunas, which are made of TPE (thermoplastic elastomers.)


Being "tight" is a function of your pelvic floor (PC) muscles.  Cups sit above them. You need to relax them for insertion and removal and then you can go back to holding them as tightly as you normally do.  Above them, your vaginal wall muscles become less elastic as you age and/or have children.

TECHNICAL NOTE:  This chart MIGHT get truncated (cut off) when viewed on a handheld device like a phone or a tablet.  48mm is the widest width and then there is a column of words that describe length.  If you can't see them, then look at it again on a "real" computer to see the whole thing.

If it still gets truncated, try this: Hold the Ctrl button and hit the - (dash or minus sign) to widen your view.  To get back to your original view, Hold both the Ctrl button and the shift button to hit the + (plus sign.) "Ctrl -" to zoom out, "Ctrl +" to zoom in.

There are four width and several length categories as denoted by the gray and white shading.
Note that "Medium" length and width are not in the middle.

Instead Softcups - Are distant cousins to menstrual cups.  The diameter of the ring is about 70mm.

*FemmyCycle Cups are the only cups for which the bodies are wider than the rims.  The body width for each is approximately 50mm.
== Teen --- 31mm rim, appx 50mm body.  38mm cup length, 57mm including the stem.
== Regular and Low --- 36mm rim, appx 50mm body.  43mm cup length, 50mm including the stem for the low, 63mm including the stem for the regular.  NOTE: The difference in overall length between the regular and the "low cervix" models is in the shape of the ring stem, there is no difference in the cup itself.

GENERIC CUPS:
Fellow cupper, Obsidian, has several outstanding entries in her blogs about generic cups.

Keeper/MC - The latex Keeper and the silicone US Moon Cup (which is made by Keeper) are the same cup but are made of two different materials.
Natu/Si-Bell - Are apparently the same cup sold under different names.  There may be other names for these cups as well.

A distant cousin to cups:
Instead Softcups - http://www.softcup.com/

Note: Those appear to be the official manufacturer's sites, not necessarily where you can buy them cheapest.  Please shop around online and in local stores for the best prices because many distributors sell them at discounted prices.


Restrictions:
Until Intellectual Property conflicts are resolved, MPower cups are for South African customers only.
At 20 Euros for shipping, Iris Cups discourages sales to those outside their home country of Spain.
The Chilean MiaLuna and Brazilian MissCup seem to only be available within their countries.
The JuJu site says that their "Products are shipped to all countries except USA and Canada."
UK Mooncups are now known as MCUK when sold to those in the USA.

  • MeLuna Classic/Sport -- Jul 10, 2014

  • Tassaway -- Feb 12, 1981 (defunct brand)

To see the list, search for MENSTRUAL CUP at http://www.accessdata.fda.gov/scripts/cdrh/devicesatfda/index.cfm

All other cups must be ordered internationally.  Just because it claims to be "made of FDA Approved silicone" doesn't mean the cup itself has been FDA Approved.  And just because a cup isn't FDA Approved doesn't mean it's bad or dangerous.  It can still be imported to the US for personal use -- but not for retail sale.
