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 *


Your Ideal Weight Range



*Frame Size

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


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″


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.


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 guess I’m at least 30 pounds 5’11 220 pounds medium frame O shape. 90% of fat in my belly legs and arms or butt don’t have that much fat. But says should be able lose weight easy. Younger I was to skinny could not gain weight now I’m 30 or more pounds over hard to believe I got 30 pounds in my belly.

    • Ted Kallmyer (Certified Macro Coach) 4 days ago

      Hi Johnny, That does sound about right. You can also have internal fat which is fat that accumulates around your internal organs. This could be as much as 10 pounds alone. If you want to lose that 30 pounds, I have a lot of resources to help you. You could start by using my macro calculator here: Flexible Dieting Macro Calculator

    None of these formulas take into account waist to hip ratio or body shape. According to most advice, if your excess weight is carried around your hips and thighs this is not as bad as when you have an apple shape. I am 5 foot 5 and weigh 152lb so I am a little overweight according to my BMI. According to your calculations, I should weigh between 126 and 130 lbs which for a pear shaped woman is just ridiculous. In my early 20s I used to weigh 140lb and I could see my ribs.

    • Johnny pratt 4 days ago

      one site at the bottom had wear you could check body,shape,frame and maybe weight. With all the checking I’m 30 pounds over mainly in my belly it was hard to believe but I guess I am. Because I have checked them all frame body shape and weight.

  3. Glenn 3 weeks ago

    Thanks I recently lost 100 lbs from 262 to 162 lbs. I’m 5 ft 11.5 inches. Your calculator say my ideal is between 163 to 167 lbs. So I guess I’m on the right track, I just need to replace some of this fat with muscle.

    • Ted Kallmyer (Certified Macro Coach) 3 weeks ago

      Hi Glenn, Great job, that’s awesome! Yes, work on building and strengthening muscle.

  4. Amy 1 month ago

    All the ideal measure formulas you are using are highly outdated.
    The size of your wrist is not indicative of your frame. That’s ridiculous. I have tiny hands and feet and small wrists, my fingers strongly overlap, but I have a massive ribcage (my bones show at the high end of the normal weight range, wide shoulders and wide hips. This is very unscientific and completely inaccurate.

    • Ted Kallmyer (Certified Macro Coach) 1 month ago

      Hi Amy, This calculator deals with “averages” and since humans have a wide range of traits and characteristics, some people will lie outside the “norms”. In general, this calculator does give a realistic healthy weight based on height and gender and does so based on scientific data that is sourced/referenced. Just because you feel that it isn’t accurate for your unique body-type, it doesn’t mean that it’s unscientific or inaccurate. It just means that you don’t fit within the average range referenced.

    Hey Mr. Ted!
    I’d just like to thank You for all of your effort and giving the opportunity for all of people around the Globe to get in touch with such amazing information, which usualy can’t be accesed easily. At least wasn’t for me! Anyways, I’m very grateful! Thank You once again and God bless You!

      My pleasure! Thank you so much for taking the time to say thanks.

  6. Princess Hoy 1 month ago

    I’m a 50 year old woman and I started my weight loss journey again last year in April.
    I was 195 pounds last year and looked six months pregnant. Now I’m 165 and according to this a medium frame but I still have fat in my midsection which now makes me look three months pregnant. I don’t understand who’s measuring this and how and I to improve on this? BMI is 23 which is supposed to be good

    • Ted Kallmyer (Certified Macro Coach) 1 month ago

      Hi Princess Hoy, BMI isn’t a great measure of health because it can be skewed easily for various reasons. Also, ideal weight is also an estimate based on averages so you have to take both with a grain of salt. You can have your body fat measured and then determine if you are in a range that’s healthy. Based on this you can determine how much more fat you should lose. Here’s my body fat percentage calculator and a chart that shows healthy ranges. Body Fat Percentage Calculator

    Hello i’m an asian. i’m 15, i’m 160cm/5,25, my wrist is 15cm. Currently, i’m 43kg/94,8 lb. Though i think i’m kinda tall and large, this web tells me that i’m small! Maybe it’s because they use Western measurement? Idk, but how much should i weigh?

    • Ted Kallmyer (Certified Macro Coach) 1 month ago

      Hi Yen, This is probably because your bones are still growing. Use the large frame setting.

  8. Gigi 2 months ago

    According to this calculator, I’m a medium frame and I’m 5-10 lbs UNDER Weight! I’m shocked because I dont look underweight at all. My wrist measures 6 inches which puts me at a medium frame. I’m 63″ and 114lbs. I am NOT THIN!

    • Ted Kallmyer (Macro Coach) 2 months ago

      Hi Gigi, 114 would be a bit underweight for a woman 5’3″. Remember that we don’t always have an accurate body image of ourselves. Perhaps work on some strength training and developing lean muscle tissue. It could be a body composition issue in your case.

    Hi I have CKD and need to have lower protein, will this slow my weight loss please

  10. Stacey 3 months ago

    This is for/about my daughter. Age 17, 66.5 inches, wrist under 5.5 inches (quite “fine boned”). Other than determining ideal weight, is there any value in this information to assist with weight loss? Such as, is there relevance between frame size and BMR? I’m guessing that two people of the same height and weight, but different frames would have different needs (considering the difference in bone v. tissue).

    • Ted Kallmyer (Macro Coach) 3 months ago

      Hi Stacey, This does give a good indication that a person is overweight especially since it does take into account frame size. If your daughter is significantly above what is considered an average weight range for her height then she may want to consider some dietary changes in order to get her weight into a healthier range. However, I will add that you also don’t want her to become obsessed with her weight either. I’ve had many clients who have dieted since they were in their teens and had unrealistic expectations for their bodies. It’s important to find a balance and focus on being healthier more so than a number on a scale.

      • Stacey 3 months ago

        Thank you Ted. Unfortunately, she is well over her “ideal weight”, but more than that, is feeling the physical impact of her weight gain. She gained a large amount of weight very suddenly while dealing with some issues, and now that she’s in a better place, wants to work on getting her body back. It really seems that reputable guidelines are mostly aimed at those who are of average/medium build though, which makes it tough to make educated decisions about weight loss when you are not in that group.

        • Ted Kallmyer (Macro Coach) 3 months ago

          Understood! Well, if you feel like she could benefit from some personalized help, I do offer weight loss and nutritional coaching. Here’s my coaching page: Personalized Macros Coaching Since she is a minor I’m happy to send all correspondence through your email.

    Hello I have a question I am 19 year old girl and 180cm/5 10 tall and I have a 17cm/ 6.7in wrist size. How much should I weigh?

    • Ted Kallmyer (Macro Coach) 3 months ago

      Hi Ingrid, According to the calculator given your height and large frame size, you should weight 71-73 kg.

  12. Libby 4 months ago

    I do not understand, this makes no sense. Most of my body is bones, yet it’s saying I’m severely over weight. Lmfao this thing is sooooooo wrong, I’m sorry but it is. I’m 68.5 and 210, only fat on my body is on my breast(I’m an F cup going up to g cup!). My hips are literally no fat on them, 50 33 50!! My wrists are small yet my frame is not, your wrists has nothing to do with the size of your frame. I’m sorry but this isn’t right one bit, maybe it just doesn’t work for someone like me. I don’t work out much, but enough to have some big thighs and butt! Idk this is just so way off from what’s healthy for someone like me. If I was 170 or under I would be dead!

    • Ted Kallmyer (Macro Coach) 4 months ago

      Hi Libby, I don’t think you understand body composition. Most of a person’s body weight isn’t bone. There wouldn’t be any health standards that would support the notion that 210 pounds is a healthy weight for a 5’8.5″ female or even a man at that height.

  13. Wood hughes 8 months ago

    My bath scale senses and uploads various info to my Apple Health app, but it doesn’t offer any way to adjust for frame size. I’m 6‘4” With a 7.75” wrist size, so all the body fat percentage, BMI, etc. seem to be calculated for medium.

    Do you know of and recommend any sensor scales that offer frame size adjustments?

  14. Debbie 9 months ago

    I’m trying out find out my ideal went for a female my age, 70 years.

    • Ted Kallmyer (Macro Coach) 9 months ago

      Hi Debbie, The calculator should give you a good idea, but people are different so take it with a grain of salt. The calculator can’t account for every factor.

  15. Anonymous 9 months ago

    I don’t think this can be correct – I put in height 175cm, large frame (my wrist is 17cm) and female, and it gave me a weight of 68-70kg. If a person with a large frame isn’t supposed to be higher than the middle of the healthy BMI range, who is?

    • Ted Kallmyer (Macro Coach) 9 months ago

      I’m not exactly sure what you’re asking but BMI isn’t a great measure of healthy weight. There are a lot of things that can negatively skew it like muscle mass and frame size.

    what formula is used for considering body frame and Ideal weight calculation

    • Ted the Macro Coach 10 months ago

      Hi Henel, The formulas are from the studies linked to in the references at the bottom of the page.

  17. Tanya Mendez 11 months ago

    Thanks for the reply Ted. I’m not familiar with the term Macros. Can you put that in Layman’s Terms for me please? Also how can I calculate (or keep track of it)? I’m not good at Math. The only macaroons that I know of are the colorful French sandwich cookies. Lol. Yeah I know it’s spelled differently.

    • Ted the Macro Coach 11 months ago

      Hi Tanya, Macros are protein, carbs, and fat. I encourage you to read the article I mentioned which explains things and you can use our calculator which does the math for you. Flexible Dieting Macro Calculator

      I want to lose some weight. I am 5 ‘ 1 and I weight 113 pounds. Am I fat? How can I loose weight without dieting or anything related to food? What is the best excersise to do?

      • Ted the Macro Coach 9 months ago

        It seems like you are in a healthy weight range for your height. You probably want to focus on strength training and build stronger muscle tissue. This will tone everything up.
