A pretty standard program is similar to what you are doing:
Mon: chest/tris
Wed: legs
Fri: shoulders
Sun: back/bis
However, the schedule doesn't determine whether you're going to put on size or not. It's how much you lift and number of reps that count.
Your schedule seems as good as any. If you're looking to bulk up, I'd do a search on this board for "mass" or "bulk", "bulking".
