He was tall. Plenty tall. You can look at photos all you want, but an inch is nothing to a guy of that size. Plus there's posture, camera distortion, anything closer the camera looks bigger. So unless you have a a photo with the right MM lens taken from the right distance with the subject standing perfectly straight, a next to known object for scale with a way to validate the position of the know object, this is a futile exercise. Just as an example. Take your phone out and take a selfie. Now go into the mirror and look at your face. Now tell me, how big is your nose? You think the mirror or the phone selfie is telling the truth?
