I tend to agree with the comment that judging height and weight is really impossible for most people... Or maybe just being honest about it is. I can’t tell you how many guys I know that are around 5"10 and claim to be 6 feet tall or more.
Without shoes I stand 73 inches, so if I'm talking to you and the crest of your head reaches my nose then don’t tell me your 6 feet tall.
The same goes with weight. I weight 286 lbs as I haven’t been inside a gym in a few years consistently. When I stand sideways and look in the mirror... and don’t suck it in… the peak of my now distended belly sticks out to the same level as my chest. Granted I can still bench my weight but I don’t feel as good about it as I did when I weighed 265 and pressed 285. Yet I again know guys who not only have much larger guts, but they have "spread out" a good deal across their whole bodies and still claim to be less than 250lbs.
Anyway the point was that most people really can’t measure very well or can’t bring themselves to be honest about what the measurement says.
