The overall dimension of the field is specced as +4.0/-0in. and the tape is specced to trisect this area. This means that +1.33in. should be the tolerance for the size of each zone. Additionally the field and carpet stretching as mentioned by other posters above may cause additional deviation from this measurement that is very difficult for FIRST/event staff to do anything about.

If 1 inch honestly effects your autonomous:
1. You have a pretty solid PID running, it should be trivial for your team to tweak the value to fix your auto
2. It is unlikely your robot will score many goals in teleop this season unless you are using automatic positioning. A driver cannot achieve inch accurate positioning from 30+ feet away. Even with auto positioning any defense at all will cause a deviation of substantially more than an inch.
