Weight Charts… Press The Easy Button

Weight charts are probably one of the easiest ways to get an estimate of what you should weigh, although many of them don’t take in all the factors that should be considered such as age, height, sex, muscle to fat ratio and bone structure frame.

Imperial Chart

Metric Chart

Are You Small, Medium Or Large??

Your body frame size or bone structure is determined by your wrist circumference in relation to your height. To determine your body frame size, measure your wrist with a tape measure and then use the chart below to determine if you have a small, medium or large bone structure. After finding out what size your bone structure is, use the imperial and metric weight charts to see what category you fall into.


Height under 5'2"

  • Small = wrist size less than 5.5"
  • Medium = wrist size 5.5" to 5.75"
  • Large = wrist size over 5.75"

Height 5'2" to 5'5"

  • Small = wrist size less 6"
  • Medium = wrist size 6" to 6.25"
  • Large = wrist size over 6.25"

Height over 5'5"

  • Small = wrist size less 6.25"
  • Medium = wrist size 6.25" to 6.5"
  • Large = wrist size over 6.5"


Height over 5'5"

  • Small = wrist size 5.5" to 6.5"
  • Medium = wrist size 6.5" to 7.5"
  • Large = wrist size over 7.5"

Multiple Methods Available

There are so many ways to assess the actual composition of your body these methods include hydrostatic (underwater) weighing, bioelectrical impedance and skin fold testing. One of the most accurate, preferable methods is the hydrostatic weighing this method is usually found at universities in their athletic department.

BMI: body mass index this method is a very simple measurement, it compares a person’s weight and height. It does not take into account the person’s chest, waist or hip measurements. See below for calculating the BMI Formula in imperial and metric systems.

Imperial system: the persons weight in pounds, multiplied by 703, divided by the square of their height in inches. See the example below.

  • Weight: 121 pounds
  • Height: 66 inches
  • 66 x 66 = 4,356
  • 121 multiplied by 703 divided by 4,356 = BMI of 19.53

Metric system: divide the person’s weight in kilograms by their height in meters squared. See the example below.

  • Weight: 90 kilograms
  • Height: 1.9 meters
  • 1.9 x 1.9 = 3.61
  • 90 divided by 3.61 = BMI of 24.93

BMI recommendations

  • BMI is less than 18.5: underweight
  • BMI is between 18.5 and 25: healthy weight
  • BMI is between 25 and 30: overweight
  • BMI is between 30 and 40: obese
  • BMI is over 40: very obese, morbidly obese

Spot On Perfect… Try This Recommended Method

Keep in mind that the figures in these weight charts are just rough ballpark estimates, if you want to be spot on perfect with your new weight loss journey, I recommend finding a university that has the capabilities of hydrostatic (underwater) weighing.
