How high does the lip of a case have to be to protect the camera on iPhone 12?

Hello! I just bought an iPhone 12. I am looking to get a case for it. Some have a raised lip of 1.2 others 1.8 and everything inbetween. I prefer slim cases but also I want to protect the camera. What is the minimum required height of the lip on the case to do so?

Thank you

1mm seems fine !

Just enough to get a screen protector on and when you set it down on its face the glass doesn't touch the surface.
