How to Determine Optimal Weight

• 1

  Take off your shoes and stand straight, with eyes forward, against a wall. Take a pencil and mark where the top of your head aligns with the wall. A friend or family member might be able to help for a more-accurate measure.

• 2

  Record your height with the measuring tape and write it down.

• 3

  Determine optimal weight based on height and sex.
  For a man, the optimal weight is 106 pounds for the first 5 feet, and 6 pounds should be added for each additional inch of height. For example, a 5-foot 8-inch man's ideal weight would be 154 pounds.
  For a woman, the optimal weight is 100 pounds for the first 5 feet, and 5 pounds should be added for each inch over 5 feet.
