choice between 0805 or 0603 ?

When PCB space is not a constraint and volumes are low (

I suppose my stuff is in that category. I've gone to 0603 for space reasons on a few boards, and my board stuffer finds it possible to work with- though he prefers 0805. He screamed when I suggested 0402. He assembles mostly by hand BTW. So I tend to use 0603 for everything new, on the grounds that eventually we'll only have to stock one size.

That is correct. 0603 is cheapest, and easier to work with then 0402 and smaller.

In the volumes you're using, with no space constraints, the 0805 is usually a better solution. Yes, they are marginally more expensive, and use a little more paste (serious considerations for large volume assembly), but the larger parts have fewer assembly problems and will handle a little more power. Rework is easier (therefore cheaper), and visual inspection is easier (therefore more accurate). 0805 parts are marked with the resistance, 0603 usually are not.

Digikey shows a 5k spool of 0603 1% resistors at $36.75, and a 5k spool of

0805 1% resistors at $39.00.

Depends on what you need. If you have high speed signals flying about then 0402 devices have significantly lower parasitics (and are comparable in cost to 0603 when board space is taken into account). If you have something where that's not an issue then 0603 is currently the cheapest solution. That will probably change fairly soon though as 0402 parts become the 'standard' part.

0805 is most convenient size for me to use with home made pcbs. and its still possible to read those resistor number codes.

although I have used 0603, only cos I didnt realise how small they were to start with.
