Assuming given space is >= 4 GB ...
I personally first set the sizes of swap (2*RAM if RAM <= 256 MB,
else about RAM + 256 MB), / (about 65% full), and /usr (about 50%
full).
I try to keep the sizes of / (100 - 135 MB) & /usr (500-600 MB) such
that there is room to expand w/ each, at least, minor release, w/o
wasting space. Purpose of the two partitions is to contain base
system specific files only. X does not come in this yet.
Next comes the partition which will contain at least /home and non
system files (/usr/local, /usr/X11R6, /usr/ports, /usr/src).
If i can squeeze in ~2 GB partition, then
${MAKEOBJDIRPREFIX:-/usr/obj} & $WRKDIRPREFIX---see comments in
/usr/ports/Mk/bsd.port.mk---go there (where ports & system compilation
occur).
Now, the remaining amount of space decides if /var goes on a separate
partition. Low space in /var will very likely make /tmp to be created
as a memory file system. If the amount of the remaining is too low (i
decreed it to be <465 MB during my last installation) for /var,
everything will go either on the partition containing /home or the
compilation partition.
Currently in ~22 GB slice & FreeBSD 5.3 installed, i have ...

Mind that above is my own brand of fuzzy logic to partitioning a slice
for personal use; besides the / & /usr partitions sizes, everything is
subject to major changes.
After doing quite a number of installations, i am still not satisfied
w/ the layout. I thought i was quite done w/ 4.x, but 5.x changed
that being bigger in size, especially /. And the partitioning
menu/screen, reached via sysinstall->Configure, sometimes does not
allow some of the values (causes "Partition too big" error message)
causing some partitions to be bigger/smaller than desired.
Oh well.
