The struts would not determine the height, but the springs could. Here are some questions and recommendations.
1) Are the springs installed correctly? The "pig tail" end of the spring has a slot that it fits into on the control arm, is that lined up correctly?
2) Spring isolators. Are the isolators installed? Are they a matching set between the sides?
3) Has the vehicle been in an accident? Is the control arm bent? Have the spindles been replaced?
4) Take more measurements than just the fender to the ground. A spot on the control arm to the ground. The control arm bushings to the ground. Upper spring perch to the ground.
Answer these questions, and take these measurements. Something will show different in these measurements, and the questions will help you figure out why the measurements are off.
