Are you measuring the SCL (length of the carapace/top shell from behind the neck to above the tail and not including the curve of the shell)? The preferred size for a year-old RES can be anywhere in the range from 2 - 3.5 inches, so there is some latitude in size for a healthy turtle.
If your turtle is healthy--- is active, basks, and eats well, then it doesn't sound like you should be overly concerned. What are you feeding your turtle, how much at a feeding?
You could concretely see if your turtle is growing (or not) by weighing and measuring him monthly (at the same time each month, a small kitchen scale can be used to determine his weight) and keeping a record. You want to see slow, steady growth.
