You’re probably wondering what the human height calculator is and if it really can work out yourmaximum natural height?

Well it’s true! It does exists.

Let me explain. Over the years extensive and thorough scientific research studies have been carried out all over the world to try and determine if it’s possible to predict a persons maximum natural height based upon a number of factors including their grandparents heights.

The results of these studies have told us that according to the human height calculator, the average height of a given male is the equivalent to the average heights of his grandparents and biological parents, which is then multiplied by a factor of 1.08 to give the answer.

Although studies have also highlighted that 95 out of the 100 males maximum natural height prediction is below the sum of their natural height plus three and a half inches.

The human height calculator also applies to females too. It shows that in the cases of women, the average height of a female is shown by the average height of their parents plus grandparents, which is then multiplied by a factor of 0.92 to get the answer.

This figure will show most females natural height quite accurately. Once again, studies show that 95 out of the 100 womens maximum natural height prediction is below the sum of their natural height plus two and a half inches.

So now I bet you’re wondering if the human height calculator can work for you right now?

Well give it a go and find out. To find out your maximum natural height you will need to know the average heights of your parents and grandparents, then use the formula shown below to work out your answer.

- Your father’s height = F cm (inches)
- Your mother’s height = M cm (inches)
- Your father’s father’s height = FF cm (inches)
- Your father’s mother’s height = FM cm (inches)
- Your mother’s father’s height = MF cm (inches)
- Your mother’s mother’s height = MM cm (inches)

If you are a male, with 95% certainty,

Your Maximum Natural Height in cm (inches) = **(F + M + FF + FM + MF + MM) / 6 * 1.08 + 8.8 cm (3.5 inches)**

If you are a male, with 99% certainty,

Your Maximum Natural Height in cm (inches) = **(F + M + FF + FM + MF + MM) / 6 * 1.08 + 14 cm (5.5 inches)**

If you are a female, with 95% certainty,

Your Maximum Natural Height in cm (inches) = **(F + M + FF + FM + MF + MM) / 6 * 0.92 + 6.4 cm (2.5 inches)**

If you are a female, with 99% certainty,

Your Maximum Natural Height in cm (inches) = **(F + M + FF + FM + MF + MM) / 6 * 0.92 + 11.4 cm (4.5 inches)**

wow. apparently my max height with 95% is about 183cm. so how come i’m only 171.5cm? it could be cos i aint finished growing yet seeing as i’m 18 and apparently guys can continue growing into their early twenties. but still 11.5 cm (4.5inches) seems like i have really missed me maximum height. why do you think this is? is there any way to gain the height i should have gained (but didnt cos of one factor or another)? is drinking alot a bad thing for me to do if i want to grow taller?

This thing really works for me! My maximum height is supposed to be 6’7″, and i am 6’7 1/2. My brother’s maximum height is also soupposed to be 6’7 and he is 6’7″. My youngest brother is currently 6’5, and 16 years old so we’ll see if he gets to 6’7 as well.

My whole family is super short!!!!! I’m 5 foot 2 and besides for my dad and one of my grandpas im the tallest in my family!!!!! I took this thing and laughed when it said my maximum height was 5 foot 1! I knew it was gonna be low! Haha well….I’m still gonna try and keep growing because so far…its been working! 🙂

It took me a while but I finally managed to calculate correctly and according to the calculations my maximum naturalistic height is 191.46457cm/1.9168m. In other words or units my adult height will be 6’3… which is amusing…. last I visited the doctor (my family doctor) she told me I will be expecting three more inches. I was 5’10.5 (5’11) that time, as expected I grew an inch thereby becoming 5’11.5 or in other words 5’12. When I was pondering over it before, I had thought I was only getting two more inches (6’2) now I see I will be receiving another three inches.. ticking off one inch from the four inches. @Dan if you wish to grow taller organically I have heard rumors of a product entitled “Grow Taller 4 Idiots” Check it out as I am sure it will interest you greatly. It’s an honest solution and I myself am contemplating over whether or not to resort to it to quicken my growth rate.

I don’t if this is crap or not, but my maximum height is 6′ 3″?

Am I doing this right? All the heights add up to 402.1 inches so this must be messed up or something? I just turned 17 and currently I am 5′ 9,5″. I’m slightly taller than my Dad and Brother who are 5’9″ and 5’8 respectively. My grandfathers were both relatively tall with my FF being over 6 feet and MF about my height. My grandmothers stood at about the same at 5’4″ both. My sisters height was correctly predicted though.

…. Well i’m supposed to be 6 foot 3 according to this thing, lol! I’m only 5 foot 8 at 14 though.. perhaps not done growing.

My dad is 5’6 my mom is 5’4, my dad’s dad is 5’8 and my dad’s mom is 5’1. My mom’s dad is 6’0 and my mom’s mom (I don’t know her height but I’m assuming 5’4 or 5’1).

It says 74.6 inches or 6’2. I hope to God this is true but maybe not (hopefully though)

If using my parents’ parents info to calculate my height really worked with such certainty then why would my height be so different from my sisters’? I would use the same people for both our calculations, correct? So we should be the same height? My older sister is 5’8″ (or less) and I am 6′ 1/2″. We are both in our 40s and don’t expect to grow any more. My little sister died at age 13 but at the time was already 5’9″ tall. I was 5’8″ at 13 so I guess she would have been taller than me at adult age.

I realize none of these are ever 100% but this one seems way too confident in itself. I know too many people whoses same sex sibling is nowhere close to the same height to make this system 95% or 99% accurate.

According to this calculations, it got my maximum height as 171 cm, I’m 15 and currently 176 cm (5’9.5”) tall, even though everybody in my family is really short, the only tall person I know is my mother’s father, who was about 180-183 cm, but I’m not done growing yet, and my older brother is 181 cm (5’11.5”) tall, even though I don’t think I can get noticeably taller, your height really depends on your parents height, for example; even though my father’s family is short, my uncle’s wife is really tall for a woman (about 5’11” or taller) and their sons are 194 (6’4”) and 186 (6’1”) tall, unlike the rest of the family.
