I'll be glad to tell you what we use but I feel I must warn you that
I don't understand  what you mean by this sentence.

Our 0603 parts (when we are allowed to use them, which isn't often)
use .036 X .040 pads with .061 center to center and a gap of .025.

Our 0805 parts use .059 X .065 pads with .091 center to center and a
gap of .032.

Hope this helps.
