See the full list of photo requirements on travel.state.gov/photos:
However, on travel.state.gov/photos, I don't see a clear list of photo requirements. There are some "Tips for Submitting your Photo", but it's incomplete e.g. they don't mention that the eye level must be between 1 1/8 to 1 3/8″ (28 and 35 mm) from the bottom of the photo. (https://i.stack.imgur.com/W1w5P.png from https://visafoto.com/us-passport-photo also mentioned that the eye level must be between 1 1/8 to 1 3/8″ (28 and 35 mm) from the bottom of the photo).
Where can I see the list of all the requirements for the photo for DS-11 (US passport photo)?
The official photo checker https://tsg.phototool.state.gov/photo doesn't mention what they check beyond the cropping and compression.
