With a few simple measurements, it's possible to estimate heights with some accuracy. Take a look at the figure below. All you need to know is:
1.your distance from the building
2.your eye height
3.the angle between the ground and the top of the building
Use this formula to calculate the height of the building:
Height = ( tan(angle) x distance ) + eye height
Example: Given a building distance of 25 meters, an angle of 37 degrees, and an eye height of 1.75 meters, the formula would be:
Height = tan(37) x 25m + 1.75m
= 0.75355 x 25m + 1.75m
= 20.6m

Believe it or not I too have a formula for working out the height of a building, especially handy should your smart, I phone or laser break down.....count the joints on the down pipes if they don't have down pipes estimate the measurement of the first floor and multiply by the number of floors(pye:bigsmileor scale of the drawing.
