Speaking for myself, I think the picture on my key is quite usable for
ID purposes (although there is some blocking), and it packs the full
240x288 pixels of truecolor jpeg into 2385 bytes. The main trick to
getting the picture this small was replacing the background with a
single color. From that point on I just cranked the compression up
untill I had a small enough file.

Looking at my keyring (contains mainly keys of people who post to the
various mailinglists I read), I see keys from 2KB to almost 14KB
(which I think is a bit over the top), with 3-5KB being the "normal"
