Body Type Calculator

body type calculatorDetermining your frame size and body type (are you an ectomorph, mesomorph or endomorph?) will help you find out your ideal weight and determine the best exercise and diet plan to transform your body.

Calculator Instructions

Determine your frame size using the body frame size calculator. First select your gender. Then enter either your wrist size or elbow breadth. Lastly, enter your height in meters or feet and click calculate.

Determine your wrist size by measuring your wrist just below your wrist bone with a tape measure. This is the smallest point of the wrist.

body frame calculatorTo determine your elbow breath extend your arm forward such that it is horizontal and parallel to the ground. Then bend your elbow such that your forearm is at a 90º angle to the ground. Place your forefinger and thumb of your other hand on either side of your elbow joint. Then use your forefinger and thumb as a gauge to determine your elbow breadth by measuring the gap between them with a ruler.

body type calculatorbody type calculatorDetermining your frame size will help you set realistic weight loss goals (use the ideal weight calculator, which takes your frame size into account). We do not all have the same size of frame; some people have a smaller and lighter frame, while others will possess a heavier build. As such, if you have a large frame size you cannot expect to weigh the same as someone with a small frame.

This is a very rough method of determining frame size and is mostly about getting you to understand that we aren’t all built the same, can’t all look the same (even if we try), to help you set more realistic goals, to focus less on a number on a scale and focus more on having a healthy body composition. As you can see this calculator determines frame size only from one measurement (upper body), it does not take the lower body into consideration. However, upper and lower body frame size is not necessarily the same. The upper body of a pear-shaped women for example may be small framed (delicate hands and wrist), while her lower body might be larger framed (heavier ankles).

Rating scales such as the body mass index, do not take the size of your frame into account, which means that is lacks accuracy in determining whether or not you fall within a healthy weight range. For example, a mesomorph tends to be medium or large framed and also carries a good amount of muscle mass. You can’t compare this persons weight when in shape with an out-of-shape ectomorph whose skeleton is slight and at the best of times carries little muscle mass.


  1. This is very helpful thanks alot !!!!.)

  2. Very helpful!!!!!

  3. I am confused. My wrist is 13 cm, my height 1.64m, and my elbow breadth is 7cm. So according to my wrist, I have a small frame, but according to my elbow a large one?! I held my elbow bones on either side, did I do something wrong or is my body simply weird 😀

    • You didn’t do anything wrong and your body isn’t weird! Elbow breadth is rather difficult to measure, especially compared to taking a wrist measurement. And precision really does matter for the elbow measurement. With regards to elbow breadth, the difference between a small and large frame is 0.7 cm! In your case for example, at your height (1.64m) a small frame would have an elbow measurement of under 6.0 cm, a medium frame between 6.0 cm and 6.7 cm and a large frame a wrist size of over 6.7 cm. You can see measurements have to be incredibly precise. Therefore, stick with the wrist measurement, that’s more likely to give you an accurate result, as there’s less likelihood of error during measuring.

  4. Does race have an effect on how much you should weigh? Being a black girl, isn’t it harder to measure the frame considering our hip bones ten to be farther apart than maybe some other races?

    • Hi Eva. Race could possibly have an impact in so far that research shows that African Americans tend to have slightly higher bone density and muscle mass, which could increase weight a little (the ideal weight calculator does give a weight range for a given frame size). However, it’s difficult to generalize for an entire race, especially one that is so ethnically diverse. There is no stereotypical African. For example, North Africans look nothing like South Africans and West Africans (e.g. Nigeria – mesomorphic body type) look nothing like East Africans (e.g. Somalia – ectomorphic body type). In terms of tracking weight/ body composition, you can always go by body fat percentage, as it will be more accurate.

      • So glad you said that admin! as a black girl myself, this stereotype that black women are apparently supposed to weigh more than other races really angers me. If you look a black and African women all around the world you see that their bodies vastly differ. I think if you want to really know what an African women’s body weight is, look in africa. most women there are very slim. this stereotype that black people are supposed to weigh more is something that originated in america, because here black people tend to be more obese due to things like poverty and lack of education. Black women are not supposed to weight any more than any other races!!!

      • @ Denise
        i think you miss understand what admin is saying here. as a black woman also I understand that physically i do not have to differ in SIZE from my non african american counterpart, but due to bone density & muscle mass i could, in fact, WEIGH MORE while looking equally thin. If you were to take a thin african woman from Somalia and put them next to a thin caucasian woman from the U.S while they may be the same size (including height & age) the Somalian may weigh more than the American due to bone density & muscle mass. I hope this makes sense. Because in reading this i remember other articles that would suggest i should weigh the same as my caucasians counterpart, when in actuality i’d have to have a lower body fat percentage than her to weigh the same because my bone density & muscular mass are slightly higher.
        we are all unique in our makeup. fearfully & wonderfully made!

  5. According to the calculator I have a small frame my wrist measurement was 6 inches. I am 5 feet 7 inches and I am very muscular. I have done karate, cycling, cheerleading, soccer, and pretty much every other sport that requires muscle. I am 19 and was recently married. I have moved around like crazy over the last year and I have gained weight. I now weigh 155lbs and I feel out of shape. I am trying to find an ideal weight for me because I have a small frame but muscles. Is there a calculator for that?

    • Hi Megs,

      The body type calculator gives a general idea of weight range based on frame size. If you have a small frame and put on muscle easily, a weight at the upper end of the range the calculator estimated may be okay. However, since you’ve done a lot of sports and probably gained quite a bit of muscle, it could be higher than that. The scales don’t differentiate between muscle and fat. The best way to track weight loss is through body composition analysis, which is the best way to see what’s going on, especially if you are an athlete. Hope this helps. Good luck!

  6. jennifer doerflein

    is it possible to be small framed and a mesomorph.im 5ft. 3in. and my wrist is 5.75 in. around.i fit the description of a mesomorph but i saw that they are usually medium boned..:)

  7. jennifer doerflein

    i also wanted to add my fingers only touch when i wrap them around my wrist? showing im a medium frame but when i measure it im a small frame lol

    • Hi Jennifer, sorry for the delay! From what you’re saying it does sound like you’re a mesomorph, especially if as you say, you fit the general description. Also, frame size is just one of several mesomorph characteristics.

  8. Hi! Thank you for this website, it’s so helpful! I have a quick question though, i can easily overlap my middle finger and thumb around my wrist, like they touch over an inch…but..
    I wear size 8-10 in pants.
    I’m a 36 B
    and i’m 5’8 and 132lbs.
    I have a more of an hourglass figure, but i usually gain weight easier on my thighs and have a very defined collarbones and neck. I’ve always struggled with this and trying to find my ideal figure and losing weight because i don’t have that much to lose, but i’m like a size 10 :/ And even that sometimes you can see my hipbones.

    Any guess as to what “frame size” or “body type” i am? Would help greatly. Thank you!

    • Thanks! It’s difficult to make a judgement without seeing you, but I think you’re more worried about body shape than anything else. It seems you that may be pear-shaped. Mischa Barton is a good example of someone who is quite skinny on top, but has a lower body disproportionately larger compared to her upper body. A lot of women are pear-shaped. It’s just more marked in some than others. The problem with losing weight, is that you can’t decide from where you’re going to lose it and the area around the thighs tends to be troublesome for most women. If you’re happy with the size of your lower body, you could try resistance training targeting your upper body to create more balance. I hope this helps!

  9. hey.here stated that i am in the small frame catogary but i was wondering how do you get a small waist and how do you get rid of the fat under the armpit and the back area? and get rid of the love handles too!i actually know i’m skinny but some areas hasn’t made me satisfied.can you tell me what to do please?thanks! :)

    • Hi Charlotte,

      Unfortunately, you cannot spot reduce. In other words, you can’t choose from where you want to lose body fat. If you’re skinny fat, you can make big changes through resistance training to build muscle. The problem with being skinny fat is the lack of muscle. If you lack muscle, then no matter how slim you are, you still won’t have a firm body. Read more about skinny fat here.

  10. My wrist is 6.25 which makes me a small frame but my elbow is 3 (if I did it correctly) and says im a large?
    I’m 5’7 and 173 lbs so does that play a role? I know I’m mostly fat, though.

    • Hi Renee!

      It’s probably best to get your body fat percentage measured. This will give you a much more accurate picture of what’s going on and what to aim for, especially if you have a lot of weight to lose. Also, the elbow measurement has to be incredibly accurate (see earlier answer to question in which the difference between a small and large frame is 0.7 cm). Weight is not the best way to track weight loss or even know if someone is healthy. Research has shown that you can be normal weight, and even underweight, but still have dangerously high levels of body fat.

  11. I was told I have a small frame. I’m not a “small” girl (5’6″ 145lb) but I guess now I have the possibility to be skinny enough.

  12. kinda confused i know i have small frame but i look larger because of my lower body…i store more fat on my legs and thighs and this is my biggest issue. i want slimmer thighs and legs.

  13. I have a small frame, my wrists and elbows are tiny, but I am also really short. I am 5’1″ but I carry the little height that I have in my legs and have an hourglass body shape. I believe I am a mix of ectomorph and mesomorph but I am not sure. I am also fairly athletic and gain muscle easily in my lower body but not my upper body (abs and arms). Help please.

  14. So if I have a large frame does that mean I’m overweight or not healthy

    • Having a large frame does not mean you’re overweight or unhealthy. Having a larger frame simply means that you would expect to weigh more than someone with, say, a small frame. Not because you have more fat, but because your frame is heavier.

  15. Very interesting, just have a question. The small frame is equal to the ectomorph? I’m not sure how the frame size plays out for the body types. Which one goes to which?

    • Hi Jessica,
      Frame size is just one of several characteristics (such as muscularity, propensity for weight gain, etc) that help determine body type. Ectomorphs tend to have a small frame. However, most people are a mixture of body types and therefore have a mixture of characteristics. If you have a small frame, are lightly muscled and would find it difficult to become overweight in terms of BMI, then you’re probably an ectomorph. Hope this helps!

  16. Hello,
    Has there been any research done with regards to body type and those with short torsos? I almost feel as if my body falls into all three categories because of what I like to call “short torso syndrome” and wonder if there are others out there who can relate! Here is my body description:

    1) I am 5’4 and 127 lbs. I carry a lot of muscle and am athletic.
    2) My measurements are 35 – 26 – 36. However, I only have about 2 1/4″ between my hip bone and my ribcage, so the narrowest portion of my waist is just a sharp indent, giving me what I would call a false hourglass image. My rib cage also seems unproportionately large to the rest of my body
    3) I do not carry a lot of fat on the lower portion of my body, have no cellulite and nice legs with good muscle definition. I also do not carry fat in my arms or shoulders. I am a C-cup.
    4) Since I have such a short torso, I seem to gather weight at my belly when I gain weight and even when slim (when you can see my rib cage and hip bones) can never get a flat belly regardless of diet and excercise (I am a long distance runner, weight train, stick to a diet, etc).
    5) I have very small wrists, fingers and ankles, but have a short neck

    Eventhough I wear a size two pants and wear a small shirt size, I always seem to look heavier or bulkier than those with longer torsos but wear a larger pants size. I believe this is because my torso does not have the space to “narrow” out.

    Are there any specific articles or excercises for those with my type of build? I have tried to do research about this and do not find a lot which makes me feel so odd about my body type!

  17. Thanks for a good article.

    Im 6.1 with a large frame (a little over 8″ on the wrist) but my upper body is very long and legs are 32″ inseam, somewhat short.

    Based on BMI or the calculations here I should be somewhere between 168 and 192 but at 168 or with 10 pounds of that Im a very unhealthy looking person with all skin and bones. At 185 to 195 I would be healthy but my muscle mass numbers would have to be lower to accomidate this range which I dont want to do.

    10 years ago I was roughly 200 with 8% body fat and could stand to gain another 10 ponds of muscle.

    25 years later Im not looking for my college weight but how do I accomidate my upper body size, reamin healthy and still fall within the range that the medical and insurance industry calculate as idea?


    • Hi there,
      sorry for not getting back to you more quickly. You’re tall and you have a large frame. That means you should really focus on your body fat percentage, not your weight (ideally everyone should do that!). The problem with weight/ BMI is that is does not differentiate between muscle, bone and fat. If you concentrate on your weight, you run the risk of trying to lose too much weight to fit some mathematical algorithm invented by the insurance companies. If you’re naturally muscular and have a big bone structure, it’s unlikely that you’ll conform to those charts. Arnold Schwarzenegger for example would probably be classed as overweight or even obese judged by BMI, and even George Clooney has been reported to be overweight by BMI standards. Clearly, both of these actors are incredibly fit and healthy. Most important is that you have a healthy body fat percentage. Also, you sound as though you have a body type that will respond amazingly to training and healthy eating. Do that through almost daily cardiovascular exercise (to lose fat), at least 3 strength training sessions a week (to maintain/ gain muscle) and a healthy diet. Your results should be pretty awesome!

  18. Hi. . I know someone has already asked almost this exact same question but the answer didn’t quite get to what I was wondering about. By measure of my wrists I have a small frame. By measure of my elbow I have a large frame. You had said earlier that even the slightest mismeasurement could put you in another category but what I was wondering is can you have a combination of two frame types? I have broad shoulders and hips and tend to get larger muscles when I am in a working out phase but then I also have very tiny wrists and ankles. I am 5′ 8 1/2″ tall.

    • Hi there,

      Yes, you can be a combination of body types. In terms of frame types, I guess it may be possible. For example, pear-shaped women often appear to have delicate hands and wrists (small frame), but have much bigger ankles (large frame). Read about the different body type characteristics here. Also, frame size is just one of several characteristics of body type. You can be a small-framed mesomorph/ a combination of ectomorph and mesomorph.
      Knowing your body type mainly helps if you are struggling to achieve the body you want: either it helps you realize that you have to adapt you expectations/ goals or it helps you change your training/ diet to help you achieve your goals. I hope I answered your question!?

  19. I am a small frame by my wrist, but I don’t fit any of these 3 body types. I’m 5’4, 135lb, 32 age. I’m a skinny fat girl. Is there a 4th body type out there? My shoulders are smaller than my hips, muscle gaining is hard for me. I’ve always have been a size 4 and I’m trying to keep myself at a 4.

    • Hi Chas,
      You sound like you are an ectomorph (small frame, lack muscle mass) that is prone to some weight gain. Most ectomorphs are not “pure” ectomorphs, but a combination of two body types. Ectomorphs will often turn into endomorphic ectomorphs (ectomorphs prone to fat gain) with age, as even their super fast metabolism slows down as they get older. It also means that muscle gain becomes easier.
      You say you’re skinny fat. People who are skinny fat often are ectomorphs. The problem with skinny fat, tends to be mainly one of lack of muscle mass. To solve the issue of skinny fat, you need to focus on resistance training to build muscle. You can read an article about skinny fat here.
      Ectomorphs, especially skinny fat ectomorphs, need to be aware that even though they appear to be skinny, they can still have a unhealthily high body fat percentage and suffer with the dangerous type of fat around their organs (visceral fat). The problem with ectomorphs is that even though they look skinny, it doesn’t mean they really are “skinny”. Basically, ectomorphs can’t skip on eating healthily and exercise, just because they look skinny. Some studies have found some underweight people to have a body fat percentage that classifies them as obese! That’s not to say this is happening in your case, just something to bear in mind. Hope this answers some of your questions!

  20. This website is very helpful!! I’m happy I found it. :)

  21. Hello! I found, like several other girls on here, that my wrist size indicated that I was of medium build (mesomorph) but my elbow size indicated I was ‘large’. Currently I am carrying excess weight due to lack of exercise and a lax diet, but even when I was at my fittest (I was a personal trainer for many years) I would have considered myself to still be ‘soft’- therefore endomorphic. (By that I mean I wasn’t really muscular looking even though my body fat percentage was about 17-18%- except perhaps in my legs and back, both were pretty muscular in appearance) However, my weight is distributed fairly equally, and I am definitely not fortunate enough to be a pear or hourglass, I was constantly working to get a bottom! My shoulders are wider than my hips without doubt, and I have long arms and legs (for my height, Im only 173cm). The more fat I lose the less ‘curve’ I have, but I wouldn’t say I lose weight with ease at all! And I feel I definitely have to ‘try’ if I want to look lean and muscular, but I am naturally strong. Now, here is my question (finally!), I struggled throughout my teens and well into my 20’s with an eating disorder, and my weight has fluctuated up to 12kg about 4 times. Do you think its possible that I am in fact an mesomorph but my battles with eating have effected my metabolism and that is why I share some of the attributes of the endomorph (sluggish metabolism, easily gained muscle but not great definition, gain weight fairly easily) but physically in many ways I tend towards the mesomorph?

    I hope that made sense! Great info by the way, Ive been curious about this for a while!

    • Hi June,

      Thanks for your question. The main thing is to keep healthy. We live in an age where people are larger than they ever have been, but the models/ role models etc are smaller than they’ve ever been. So I think that creates a sense of confusion of what we should look like and what is healthy. I like body types because it gives people a sense of what they can achieve for their body. In terms of body shape, you do seem to be an inverted triangle shape (i.e. lower body smaller than upper body). Most people are a combination of body types. You sound as though you might be a combination of mesomorph and endomorph. Women are unlikely to be pure mesomorphs, even if they are naturally muscular, but tend to have some degree of endomorphy (it’s part of what makes you female). Also, with age, metabolism naturally slows down so we all become more endomorphic and have to work a little harder to maintain a healthy weight. But with healthy eating habits and regular exercise, you’ll look more mesomorphic (gain more muscle) and less endomorphic (fat loss). Hope this answers your question! :)

  22. Wonderful website, but how do I figure out if I am an endomorph or mesomorph? I have qualities of both.

  23. Makes me feel much better about never shedding significant pounds, it’s because I am not overweight!!!
    Thank you :)

  24. Hey, really appreciate this website!
    I can’t get the calculator to calculate my body frame? I think I am a mesomorph though, because I gain muscles easily!

    I type female gender, wrist size 17cm, elbow breadth 7cm and height 1.74 meters.. I click calculate, and then it just aska me to “please type “either” a wrist, “or” elbow breadth”
    What does that mean?? It bothers me I can’t calculate my body frame..

    15 year old girl from Norway

  25. Nevermind! I sorted it out, I am a medium frame :)

  26. If I have a medium frame size, does that mean that I have the body type mesomorph?

    • Hey there,
      Frame size (in your case medium) doesn’t determine body type, but is one of the characteristics of body type. For example, endomorphs and mesomorphs tend to have medium or large frames, while ectomorphs tend to have a small frame. Frame size is also useful in making sense of your weight. If you have a medium frame, you are more likely to weigh more than someone with a small frame. Basically, body weight isn’t a great way to determine health, because it doesn’t differentiate between frame size (a larger frame will weigh more than a smaller frame), amount of muscle mass or body fat.

      Read this article on the mesomorph body type for the characteristics of a mesomorph. If you are athletic and gain muscle easily and lose body fat relatively easily you may be a mesomorph.

  27. Weird, I’m 5’3, 112 pounds and have 20% body fat, but according to this and my 6″ wrist I have a medium body type and according to my 3″ elbow breadth, I have a large body type but I wear size 2. Obviously, as this is based on wrist or elbow measurements, it does not take into account buff arms on a petite girl.

  28. So because I have an endomorph frame size does that mean that I can’t get slim or get toned and have a nice body that I will like and feel comfortable in??

  29. Also I know this might not have to much to do with this but I am quite fit do sport every day but I just can’t seem to get rid of my extra weight. I have a belly and extra fat on my back plus on my thighs and two chunks on either side of hip bones! It’s really frustrating that I can’t get rid of it what should I do! I’ve tried everything! I just can’t seem to find a way that actually works!!!

  30. helo,
    my body type is ectomorph but i dont seem to know why i have knocking legs anytime i’m walking my legs seems to be knocking,pls do you knw any excercise that would help in keeping my legs apart while walking..

  31. Hi, is it possible to be a mix of body types? I have some characteristics of ectomorphs such us small bones, long arms and legs and linear appearence but I also have a tendency to gain muscles mainly on my legs which would make me a mesomorph. I used to be super skinny when I was around 12 years old but then I joined the track team (sprinter) and gained a lot of muscle. I’m confused as to which body type do I fill into and what would be a proper exercise program to achieve a slimmer and skinnier appeareance (little muscle). Thanks
