There's a growth calculator here:
To adjust it for your preemie, simply subtract the amount of time that he was early. For example, my son is 8 months old, and he was 2 months early. So if I were using the calculator, I'd probably check using 6 months, to see how he's doing for his adjusted age.
Hope this helps!
