Measure your shadow length
Once you are all set with the location of the sun, measure your shadow in inches from the toes to the top of the head with the help of measuring tape.
Dividing height by length
After taking the two readings and noting them, divide the measured height by the length of your shadow and note the number you get. This number will be the proportion you will use for calculating the impossible height.
Multiplying shadow length with obtained proportion
After measuring the length of the object’s shadow a measuring tape, multiply it with the proportion or number you calculated in the fourth step.
The required height calculated
Upon multiplying, you will get the height of the object in inches. To find the height in feet, simply divide the number with 12.
