I have the same requirements as yourself, just a separated /home
partition for fat and painfless re-installs.

What I have alwyas done since Ubuntu came out, and appeared to work
well in practice (at least for me ! ;-) :

- around 10 GB for '/'. A default install takes about 2.5 GB, so that
leaves lots of space for the system to "breathe" (package cache,
logs, /var, god know what else ;-), and for you to add as many
applications as you might want.

- 99.5% of the remaining space of the disk for /home.

- The last remaining bit, for the swap partition. Although I have
plenty of RAM never run out (according to the system monitor at least),
the kernel still wants to put a bit of stuff on it, go figure.
As a guide, give it between one to too times the amount of RAM on your
system. I have 1 GB of RAM, so I put 2GB of swap. The swap costs not
much disk space compared to home, and it can save your bacon if the
system doe srun out of memory for some reason. So, it's not worth
cutting corners here... better put a bit more swap than a bit too
few ;-) So let's just say twice the amount of RAM.

So to sum it up, with a 100GB drive:

10 GB for '/'
88 GB for '/home'
 2 GB for 'swap'

HTH ! ;-)
