0603's are 0.060" x 0.030" (1.5mm x 0.75mm) These aren't too bad to deal with.
0402's are 0.040" x 0.020" (1mm x 0.5mm) These are strating to get
tiny, but are pretty standard on cell phone circuit boards. I solder
these very carefully, and try to ensure I have more than one left
because inevitably I'll breath too hard. These are very hard to find
on the floor.
0201's are becoming more popular Grrr. surface tension of the solder
on the tip of your soldering iron is now a pain.
And as Leon mentioned 01005 (half again as big). Thankfully I've never
had to deal with those.
