Shadow Length Calculator

Shadow length calculator is an essential online tool which calculates the length of the shadow projected by an object due to the Sun. The tool uses the angle of elevation to find the length of the shadow of an object. 

To calculate the shadow of an object, the angle of elevation is also required. The shadow length increase and decreases depending upon the time of the day. The shadow is formed on the opposite side and the following formula is used to calculate its length.

L = h/ tan α

Where,

  • L = Length of the shadow
  • h = height of the object
  • α = angle of elevation of the sun

Example on Shadow Length Calculation:

Consider a pole of length 10 m projecting a shadow. If the angle of elevation of the sun is 45° then, the length of the shadow will be,

L = 10/ tan 45°

Or, L = 10 m

Thus, when the sun’s elevation is 45°, the length of the object will be equal to the length of its shadow.
