The best capacity for each range of dimensions (highest capacity cups v 2.0)

These are the highest capacity cups. Note: unless you have an extremely heavy flow, there are many other cups to choose from. Most cups have a higher capacity than pads and tampons.

The dimensions are body length x max diameter. The capacity column is to the holes only.

Meluna XL Shorty44x47, up to 59 mmTab, ball or ring. Only the tab can be trimmed/removedU16 mlA vast majority of cuppers can use a longer/higher capacity cup. Three kinds of stiffness

A unique design that prevents the cervix from sitting in the cup.
FemmyCycle Low Cervix43x48, 63 mm7 mm ringU30 ml

Has a smaller ring stem but otherwise identical dimensions. Might not be the best choice for a really low/dangly cervix

Fleurcup Large52x46, 70 mm18 mm tab, trimmableU29 mlDoesn't get shorter inside out. Anecdotally less likely to overflow when full to the holes. The grip rings are dashed but can be filed down

Some of these cups are very similar, but the specific capacity you can achieve depends on your anatomy. It's essentially about finding your limits. It's possible that your best option is to flip one of these cups inside out to shorten it.

U-shape refers to cups with a very rounded bottom. V refers to the more pointy cups, but the difference is very subtle. Elsewhere you may see references to the V-shape that imply the nearly obsolete narrow-bodied shape (Mooncup UK, Keeper, Femmecup).
The U-shaped cups have more of their capacity in the bottom, which is great for a dangly cervix. However, if a cup sits really low it might be uncomfortable (the opposite is also possible).

If you have a very low/dangly cervix, you might need to get a high capacity cup even if your flow is not too heavy (your cervix will reduce the capacity).

The Femmycycle is unusually shaped (the rim diameter is 36 mm). It's generally not recommended to get it as your first cup. Some need to drill holes in the cup to be able to use it (proceed with caution).

Honourable mentions:
-Merula (similar to the Femmycycle, also not the best first cup)
-Lunette 2 - same dimensions as the Fleurcup, stiff, pointy
-SckoonCup, LenaCup - similar to the Fleurcup but slightly shorter
-Gaia Cup Large - similar to the Yuuki and Meluna XL
