Is a shadow on the ground, cast by sunlight, the same width as the object that cast it?

Obviously, the length of an object cast in the morning or evening sun accounts for nothing in measuring how tall an object is—but what about side-to-side measurements?

I am trying to measure a building by satelite imagery and have only a ground measuring tool (Google Maps) and shadow cast by the morning sun to go by. The roof is too vague and complex. But I can measure the shadow, side to side. (the length is obviously shorter)
