Depends where in the EU you are?
In Germany, the biggest standard off-the-shelf condoms at neighborhood pharmacies are "Durex King Size", which are 215mm x 64mm --- however, the 'ring' at the base is just 57mm, with the lower part of the shaft area narrower still, at 54mm!

This is still an improvement over 'standard condoms' in terms of length, but not really in terms of girth.
However... there are lots of other options online... but it would be useful to know which nation you are in to respond to this more fully.
Also be aware that Trojan Magnum condoms can no longer be sold (legally) in the EU, as they are 'not recognized as a condom' under EU guidelines.
So unless this situation is rectified, once currently available stocks are gone, that'll be it.. unless you import your own from the US. [
