 ```HI, This is just a free comment, not an "answer" to your question, which only a G-A Researcher with a blue user name can post. Do I understand correctly that you are asking about maximum field of vision, how many degrees from straight ahead one can see right/left, up and down? My own estimate is ca. 110° L/R and 80° U/D, but that is only rough, and only individual. I am sure it varies. "And how can vision/perception be a tool of measurement in architecture?" Can you explain a little what you mean with this question? Are you asking about ways one can estimate dimensions of/in a building just by "eyeballing", or maybe with the use one's hands, or a 90° or 45° angle (sheet of paper) to help estimate dimensions? (For example, by sighting along the lines of 45° angle, bottom horizontal, top to a point on the building, that point will be roughly one's distance from the building plus the height of one's eye from the ground.) Let us know?```

 ```Here's a Wikipedia article that says you can see 180 degrees, but only 140 degrees with binocular vision: http://en.wikipedia.org/wiki/Field_of_view```

 `However, women have 360 degree vision.`
