I am learning openGL and I have a question. Why when I have a square size 4x4 does changing the z value by 2 change the size of the square so drastically? I am using gluPerspective() with fov 90 correctly and I am using glMatrixMode(GL_PROJECTION) and glLoadIdentity() before it. Any help would be appreciated.

Thanks.

This isn't really related to your problem, but doesn't a 90 degree fov seem a bit extreme? I found around 60 to be much nicer looking IMHO.
