What is the nominal size for a swap partition with 14.1?
I have read rules of thumb that run from 1x to 3x of memory. What is currently suggested for 14.1?

The old rules for swap have been negated by the increase in default RAM. The old rule of thumb was 2X RAM, but that was when 256MB or 512MB RAM was the standard.

If you plan to have your machine hibernate, the swap partition should be more than the amount of RAM, as hibernation saves RAM to swap. Otherwise, if you have more than 4GB RAM, a swap partition of 1GB should be sufficient. On the P4 box I'm using right now, I have 4GB RAM, uptime is more than four days (a power failure forced a restart), and I'm using about 1MB of 2GB swap.

Depends on how much ram you use, and how much ram you have, what you're using the computer for.

For example, if you want to hibernate to disk often, and a running desktop session uses about 2GB ram, it would be wise to have at least 3GB swap space.

There isn't really a suggestible amount, if you have free space, it doesn't hurt to use more than you might need.
If you have limited ram (a small amount) most people would use x2 the amount of ram for their swap space.

i have 8 gigs of ram and 1,85 gigs of swap, never run into problems.

In the early days of computers, hard disks were not that much slower than real memory, and real memory was incredibly expensive. Nowadays we find that hard disks have really only sped up by a small factor, whereas memory has sped up by millions of times, and memory is pretty cheap too. The usefulness of swap (aside from hibernation) no longer exists. If your system got into a state where it really started using more memory than you have and started to page out/in, your entire machine would grind to a slow death. Your expectations of program performance would dip so fast you'd be better off just restarting the machine and maybe adding more real memory.
