In this case, the doorknob is installed 48 to 54 inches above the floor, specifically to raise the knob out of the reach of small children.

Standard slab doors for interior are 80 inches high. But for doors that are more than one inch or two more or less than 80 inches, some adjustments door knob height are probably better.
