A slight difference (1/2 inch) is is acceptable but if it is too much, then something could be wrong somewhere.
The struts and springs are the main possible cause. Other components to check would be the control arms, stabilizer links, strut mount and even could be a body problem.
When the front left sags, it might not be from the front. Check the rear to see if the right is higher than left. When rear right height is higher than left, it would push front left down.
