Ideal Body Weight Calculator

Do you know what your ideal body weight is for a person of your height, frame size, and gender?

Use this accurate body weight calculator to figure out what your ideal weight is.

*Frame Size

To identify your frame size use a measuring tape and the height chart below.

Women

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 than 6″
  • Medium = wrist size 6″ to 6.25″
  • Large = wrist size over 6.25″

Height over 5′ 5″

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

Men:

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″

If you don’t have a measuring tape you can use this simple (less accurate method):

Grip your wrist using your thumb and longest finger.

  • If your finger and thumb don’t touch you are a LARGE frame.
  • If your finger and thumb just touch you are a MEDIUM frame.
  • If your finger and thumb overlap you are a SMALL frame.

Your Ideal Body Weight

Knowing your ideal body weight is a good first step to take before you start macro counting or flexible dieting. This helps you to have realistic expectations and to establish a healthy goal weight.

Understanding your optimal weight can help you with the following aspects of dieting:

  • Allows you to set realistic weight loss goals.
  • Prevents the thinking that weight loss is necessary when it isn’t.
  • Gives you a baseline to use for building muscle.
  • Helps with maintaining a healthy weight for your height.
  • Shows you a goal to strive for if you are underweight.

Why Frame Size is Important

Other ideal body weight calculators don’t factor for frame size and this is an important factor in determining an ideal body weight for a person of your height.

The term frame size refers to the mass of your skeletal structure. Those with more bone mass will weigh more than people with less bone mass who are of similar height. However, this isn’t factoring for bone density.


Example:

A 5’6″ woman who has a large frame size should weigh between 139-143 pounds, whereas a 5’6″ woman with a small frame should weigh 124-128.


This feature is why our ideal body weight calculator provides the most accurate results possible and paints a more realistic picture of what your ideal body weight should be.

How Optimal Body Weight is Calculated

Our calculator uses two well-respected formulas for determining ideal body weight. For women, the Robinson formula is used and for men, it uses the Devine formula. (see the references below)

While these formulas can’t account for all individual differences that may contribute to a person’s optimal weight, they do provide a good estimate of what’s ideal for a person of your height.

Taking This Further

Once you have determined a bodyweight that is in the ideal range for you personally, you can use that information to establish a body transformation goal that’s appropriate.

You can then use our TDEE and macro calculator to determine how much you need to eat in order to achieve that goal. This calculator uses the flexible dieting approach that doesn’t prohibit foods or certain ingredients but allows you to eat what you love as long as they fit your prescribed set of macros.

    I am a large frame. I have not recently been below 200 but I am 6ft. I would like to get down to at least 175, perhaps lower. I few like at this weight people will criticize me for being too skinny but I also think people are biased today against people who are skinny. I think it would be healthier and my BMI would be in a normal range there.

      Hi Laura, It looks like you’re in a healthy weight range for your height. I’d just recommend eating right to build some more lean muscle tissue.

    I am 5’3 and weigh 113. I didn’t have anything to measure my wrists with… so I had to go with the less accurate way which was the longest finger and thumb wrapped around my wrist. The results I got from that was that I am a small frame because I can touch my pointer and thumb perfectly and when I do middle and thumb finger it overlaps. So naturally I am in the right weight category for my height and frame, but the last time I went to the doctor she suggested I lose a few pounds! Not sure if I should because under 113 fr my height might be too low, but then again I guess my doc knows best. What do you guys think?

      Hi Ginger, Your best weight is the weight that you feel the healthiest. Unfortunately, many doctors aren’t trained in areas associated with weight loss or nutritional needs etc. so their own personal preferences and bias can come into play in this area. Based on my experience 113 seems pretty healthy for your height. The only thing that I would check on is to see how much of that 113 is lean mass. Strong muscle tissue is the best as it helps with functional movement as well as keeps your bones and joints healthy. Perhaps your doctor was referring to this?

    Blood vessels stiffen and arteriosclerosis occurs as we age, does this mean we should be as thin as possible to avoid cardiovascular events? Hypertension occurs more often as people age.

      Hi Mark, Being overweight is a risk factor for cardiovascular disease so keeping yourself at a healthy weight is important for overall good cardiovascular health as you age.

    For a woman 72 years old with a large frame, your weight chart is completely wrong. Only If you are attempting a skeleton you are on target!!

      Did you enter your height correctly? If you share that I can double-check your results. It’s usually pretty accurate but you do have to remember that it is showing “averages” You could be a little lighter or a little heavier and still be healthy.

    I was surprised. I’m 56 inches tall (143 cm) and have a medium frame. My ideal range is 108-112, and ive been fluctuating in between those weights lol. Sometimes ive dipped to 106 but only when I’m depressed and dont eat. I ballooned up to 117 lbs when I was severly bloated 2 weeks ago to the point where I had to go to the ER. It went down alot after that.
