Height Comparison Tool: Celebrity Height Difference and More 19

The height comparison tool helps give an appreciation of height differences. It works for a wide variety of people and objects. For example, you can compare celebrity heights. Other height comparisons include presidents, nationalities, hominids, fictional characters, and athletes. And beyond people, other possibilities are animals, buildings, vehicles, and even celestial objects. The height comparison tool can also do custom height comparisons. You input height measurements and perhaps even a custom image.

Press the ‘Next’ button to see another random height comparison. Otherwise, use the forms labeled ‘Left’ and ‘Right’ below to setup your own height comparison. Choose a category and subject to compare and then press the update button. Don’t forget to share your height comparison by using the copy to clipboard button. You can then paste it on social media or anywhere on the web. See below for more information on the height comparison tool.

Using the Height Comparison Tool

The height comparison tool can be used in the basic way explained above. It can also be used to do custom height comparisons. For example, if you want to compare your own height with, say, Robert Wadlow, you can do so as follows: Set Robert Wadlow for one side, and then for the other side select the category ‘Average Person’. Then select either average male or female. Next input your height.

If you want to get a bit more advanced you can use a picture of yourself. It should be cropped so that there is no space above or below your body. You can do this with Microsoft Paint or Word. Next, upload it to a file sharing service such as Drop Box. Finally, get the url for the image and paste it in the image url text box.


You might have noticed the adjustment field. This is to account for such things as footwear, like high heels, and slouching. It is typically set at 1” as that is the approximate thickness of most shoes. But for celebrity height comparisons where women often have high heels, the adjustment can be changed to, say, 4”. To see an example of this, consider the Jennefer Aniston height comparison with Zeng Jinlian, the tallest women on record to have lived. While Jennifer Aniston is wearing what look to be about 4″ heels, Zeng Jinlian is hunched over with her scoliosis and so is given a -4″ adjustment. The adjustment field can also be used for other objects such as, say, a flag pole or antennae on a skyscraper.

Length Comparison

The height comparison tool can also compare lengths as follows: If the width of an image is much greater than the height, the length data is also provided in the output. The length data is secondary as it is dependent on the image proportions, and thus may not be as accurate. That being said, subjects like the Titanic and Blue Whale were added with correct length as the priority. To achieve this for a custom image, set the height to the true length multiplied by the image height in pixels over the image width in pixels.

Units for Height Comparisons

You can choose between metric and imperial. The input is then either cm or inches and feet. The output automatically changes to larger units such as m, km, and miles as larger objects are compared.

The Height Comparison Scaling Exponent

You may have noticed the scaling exponent field. This is the power to which height scales with mass by, and thereby volume too. Other height comparison tools assume a cubic relationship, where proportions are maintained as people get larger. This is in contrast to the Body Mass Index, which assumes a square relationship. In actuality, humans scale somewhere between cube and square, perhaps 2.5. That’s why this is the default scaling exponent.

The scaling exponent only comes into play when doing height comparisons that use the default male and female silhouettes. This is because these, unlike the specific images, must scale to a variety of sizes.

With a scaling exponent of 2.5, people get a bit narrower as they get taller. If you increase this number, this will be diminished and vice versa.

Origin of the Height Comparison Tool

The height comparison tool was originally built to give people an appreciation for tall people and height differences. This explains the presence of Robert Wadlow, Zeng Jinlian, and Yao Ming. The project grew from there to look at tall outside of humans. That’s where Chewbaka, the Saturn V rocket, and the Burg Khalafi came in. Going forward, the plan is to include anything noteworthy for height, whether tall or short, as well as interesting for comparisons sake. This includes ancient hominids, presidents, athletes, celebrities, fictional characters, and inanimate objects.


Perhaps you feel like contributing to the height comparison project. The simplest way is to gather some height data, preferably in metric, and send it to TallDotLife@gmail.com.

If you have time, images would be helpful too. Please remove the backgrounds and crop to fit the subject. There are many programs you can do this with, Microsoft Word being just one. If you do provide images, please make sure they can be shared for free, such as with a Creative Commons license (Flickr and Wikicommons are good places to look). Please include the attribution link or html code.

So what do you think of the height comparison tool? Do you have any suggestions?

Please share your height comparisons by using the copy to clipboard button and posting it to social media or anywhere on the web.

    Hi, brilliant tool, just want to suggest to bring the characters close in comparison chart and if possible display lines in the background for better understanding. Thanks.

      it’s reaching here because it is suppose to be a perfect body type which means straight broad shoulders but usually our shoulders sag lower than a perfect illustration.

    • M

      I agree. Something seems way off with this. I did someone who is 6’5 I am dating and I’m 5’7 and it has me way way taller than I actually am next to him even in heels.

        You’re only ~15% shorter. It may seem like a lot relative to how much humans typically very in height, but when you see it on a screen in front of you, 15% isn’t very much.

    Heels don’t add their exact height to the wearer’s height because they slant and people pivot off the heel, not the ankle. Unless the shoes are stacked platforms and you measure the heel height starting from under the heel, then you often lose as much as 2″ off the actual heel height.

  • Celebrity Watcher Review

    Mandy Moore is at least 6′-10″ barefoot or in flats. A true giantess among Wonder Women. She learned to slouch like a pro during her dance-pop era because they tried to turn her into another teen dance-pop girl clone. Fortunately, she was already a pro voice on her own and went off and did her own thing for which we can all be grateful. A true towering Wonder Woman.

    Also, another true towering Wonder Woman, Hilary Duff, is very likely 5′-0″. She just always carried herself tall, well and proud and that seems to add at least another inch to her height. A true giantess among Wonder Women.

    This celebrity couple isn’t the first on the list with a height difference of a whole foot or more and we’re starting to think the old saying about opposites attracting really is true (at least when it comes to height).

  • Lollipops.1606

    This was a good representation for me to see how much of an actual height difference that there is between my significant other and I.

  • Alzie

    I did a comparison on here to see how I looked next to my boyfriend, it said I came to his neck but in reality I only reach his chest? And that’s standing up straight ?
