What is the ideal weight for a person who is 5' 6'' tall and in the fourth grade?

Age is usually not used to determine ideal body weights. Normally we start with women at 100 lbs and men at 110 lbs, and add 5 lbs for each inch over 5 ft in height. Note that this is often at the lower end of a healthy weight, as active individuals may be able to healthy at 10-20 lbs over this figure. Also women could add 10 lbs and men an additional 20 lbs for increased musculature, if applicable. Sorry, "big-boned" doesn't count.
