There's a reasonable discussion of this in Ubuntu's BTS at


with lots of links to articles elsewhere. Basically, there are lots of
reported (real and potential) issues with smaller sizes, so we've
picked a larger size by default for the guided partitioning. Feel free
to pick smaller if you like and if it works for you.

(The Ubuntu and Debian UEFI support is broadly similar, sharing a lot
of code and ideas.)
