In you pic,  and using the trailer as a measure  (standard height is 13' 6")  that tractor is approx.  6.5 feet at the bottom of the windshield and windows,  and the top of the cab near 9.5 feet.   The body side to side can be anywhere from 6 feet to 8 feet,  depending on the maker and body style.    

Stopping distance can vary depending on load weight and distribution,  type of load,  speed,  and road surface to name a few things.     For instance,    a  truck with an empty trailer of any type is more apt to slide the trailer than one loaded moderately,    thus load distribution can be important in holding the rear of the trailer down.  A heavy truck , or a light one on wet roads, will need even more room to stop.     Some loads are mobile,  such as livestock,   bulk, and liquids,   and can move inside the trailer if you try to stop quickly,  causing unexpected motions that thwart efforts.  

Because of the high locations and dependency on mirrors,   there are blind spots on all sides of a large truck.   Biggest are on the right and directly behind,  with smaller ones along the both sides of  the unit and directly in front under the hood.   Please,  give the large trucks plenty of space on all sides,   use your headlamps in all reduced visibility conditions,  and make sure you are able to see both headlamps in your properly adjusted rearview mirror before moving back  over in front when passing.
