How do you determine your ideal body weight?

Question

Does anyone know what the formula is for doing this?

Answer 1

this is old school now,
but say someone is five foot.
Five feet equals 100 pounds plus or minus 10 percent.
So a 5' person should weigh in the range of
90-110 pounds.
Say if 5'6".
5 feet equals 100 pounds.
6 inches equals 5 pounds per inch- equals 30 pounds.
so if 5' 6"
ideal body weight would be plus or minus 10 percent:
100 +30 = 130 + or - 10 % = 117-143 ideal body weight range.
