Things You'll Need:
- A scale
- A calculator to find your ideal weight for height
-
Step 1
Start with a constant. Height and weight charts would put the ideal body weight for a 5 foot man at 106 pounds.
-
Step 2
Determine how many inches over 5 feet you are. If you are 5'8" you are 8 inches taller. an ideal weight calculator would multiply this difference by 6 pounds additional pounds of ideal body fat weight if you are a man. In other words in the 5'8" example you would multiply 8 times 6 to get 48 more pounds on a healthy weight chart.
-
Step 3
Add the amount in step 3 to the amount in step 2. If you're a man, an ideal weight calculator would add 106+48=154. For a man with a medium frame, seeking to find what is my ideal weight, your ideal body weight is 154.
-
Step 4
Take into consideration the size of your frame. If you have a small frame, you will subtract 10% of the average body fat weight. An ideal weight calculator for the man in this example, 154-15=139 pounds. If you have a large frame, you will add 10% of the average body fat weight. For the man in this example, 154+15=169 pounds.
-
Step 5
Determine the size of your frame. Put your index finger and thumb of your right hand around your left wrist. If the fingers overlap, you have a small frame so an ideal weight calculator would subtract the 10% as shown above. If your fingers touch, you have a medium frame so you can skip 5. If your fingers don't touch, you have a large frame, so add the 10% as shown above.
-
Step 6
This formula, like any ideal weight calculator, has no way of differentiating your fat/muscle ratio. The ideal body fat weight in athletic people is higher. If you are very athletic and you're wondering what is my ideal weight, you may be heavier due to muscle but still have average body fat or even ideal body fat. It only determines ideal body fat by presuming your body fat weight based on height and weight charts. You can get a body fat analysis for a more accurate reading on ideal weight for height if you are athletic.
