Well, the correct procedure is to allways, allways, look at the datasheet. Of course, I do not follow that procedure. A good point (but not the best) is to take care of it with some space between the IC and other parts. So, a new component would have the biggest dimension found in the market for that footprint. I prefer to make a new footprint, because I dont like the style of the silkscreen of the ICs on the PCB library.
