The size of a shadow has everything to do with placement of the light source, the object, and the background on which the shadow is cast. In general, if the light source is close to the object and the background is further away then the shadow is larger than the object. The opposite is true if the light source is further away. Another part of the equation has to do with angles. This is what we commonly observe happining to shadows at different times of the day; long shadows in the morning and evening and smaller shadows around the middle of the day.

Measure height and shadow af a smaller object --- call these h1 and s1 measure the shadow of something larger like a tree. call this s2 its height is the unknown call it h2 use a proportion to solve the problem h1/s1 = h2/s2 substitute in the measured amounts, rearrange the equation (proportion) and find the answer.
