there's no fixed answer, but my rule of thumb is
if RAM < 1 GB, set swap = 2 x RAM (or bigger)
else
set swap = 1 or 2 GB
Swap only really allows your system to take longer to grind to a halt if there's a runaway process.
Most of your progs should fit in RAM with a bit in swap. The more swap you use, the slower the system.

The rule of thumb for swap was RAM x 1 1/2 or x 2 as stated.

If we are talking a new system with 1gb of ram or more 512mb is more than enough, unless running heavy scientific math programs then bumping the swap up would be smart. The rule was set when pc's had a very small amount of ram, this is not the case with newer systems.

follow the ram=swap unless your, video editing (dvd movie? may need larger swap, re mastering liveCD = more swap, ie; 4 gig LiveDvD 2-4 gig swap or temporary swap file. if you make 700mb liveCd and you have 1gig swap + free space for ISO then don't worry. I just don't know the reqs. for a web server.
