0805 - 2 X 1.25 mm
0603 - 1.6 X .8 mm
0402 - 1 X .5 mm
0201 - .6 X .3 mm
Currently I buy and hand solder down to 0402s (small quantities).
Down to 0603 is a piece of cake but problem with 0402 is visual
confirmation of proper solder joint and for that I either use a
camera (macro shot) or microscope. Just using a DIMM isn't good
enough.
This is coming from someone who needs glasses in order to read or see
just about anything properly in a 3' radius. Those with younger eyes
will be amazed at how something that appears daunting at first soon
becomes a walk in the park. Many of us can probably recall when
soldering even a 1206 (3.2 X 1.6 mm) seemed like an impossible task.
