The length of shadow to your height is proportional to 1/Tangent (sun's altitude). If the sun is low in the sky (10 degrees), your shadow would be 5.67 times as long as your height. The corresponding ratio at 5 degrees is 11.43 . (So an average height person (5.8 feet) would have a 66 foot long shadow).

What time of the day is the shadow longest?
