We Know How Tall You Will Be (Sort of)
It is normal for minors and teens to wonder how tall they will get when fully grown up. But the thing is that there are not many reliable ways to figure that out. Here, we have an online tool that estimates your future height based on affecting factors, such as genes, family background, lifestyle, etc.
Our quiz is among the most precise tests on the internet. But you should know that there is no scientific method to tell how tall a person would be in the future. However, we used the most recent data and researches to provide you with the most exact prediction possible. (More on this below).
How Does Our Accurate Height Calculator Work?
According to 2017 research, genes determine 86% of your height. The other 24% is affected by environmental factors such as lifestyle, food, and bone structure health. This is how our test answers “how tall will I be?” considering all the said influencing elements.
Genetics
Analyzing all your genes through an online quiz is impossible. But when finding the answer to how tall you will be, we look for clues. So, you are going to face some questions about the appearance and physical features of your family members. That will help us predict if you have proper genetics to be a tall person or not.
Lifestyle
Our How Tall Will I Be quiz investigates your lifestyle as well. That is because there is a 24% chance that your height will change due to environmental factors. For instance, people who sleep less than 6 hours a day during their growth age are more likely to be short—because most of our growth happens while sleeping. So, you should answer some questions about your daily routines, habits, and behaviors to help us estimate your future tallness or shortness.
Hormones
Another factor that makes any estimation difficult is hormones. For example, in boys, high levels of estrogen result in slower growth speed and short height. Our test offers questions that reveal any clues if you have high levels of female- or male-related hormones.
Things to Know Before Asking, “How Tall Will I Be?”
We all wonder what type of body will we have in our 20s or 30s. But that should not become anxiety or unnecessary worry. Here are things you should know before taking our quiz.
No One Has a 100% Accurate Prediction
As of 2021, only 800 height-affecting genes have been discovered. Even scientists claim that your tallness is a monogenic matter, meaning all your genes are probably involved. So, it is impossible to find out how tall you will be exactly. And that is because there is no way to analyze your genetic structure, figuring out how it influences your height.
You Keep Growing Until the Age of 26
There is always hope. Even if the How Tall Will I Be quiz claims that you might be a short person. According to the most recent data, humans continue growing up to 26 years old. So, you might still get taller while you think your puberty is over.
It Is Not All About Your Parents Height
Do not predict your future tallness by looking at your parents’ height only. There are other factors involved as well. It is pretty common for humans to grow taller or become shorter than their father and mother.
Medical Height Calculator Is Not What You Think
The only accurate medical method to calculate your tallness is bone age analysis. It includes inspecting your bone structure via X-Ray, estimating how it will grow in the upcoming years. But it is not a recommended technique for kids as it exposes them to unnecessary X-Ray.
How to Guess How Tall You Will Be Without a Test
Okay, not everybody trusts an online quiz to calculate their future tallness. And it is completely understandable. Here, you find three other methods and formulas to manually estimate your child’s height without a test.
Method #1: Horace Gray (1948)
If the target is female, reduce the father’s height by one-thirteen (first multiply it by 12, then divide it by 13). If the target is male, increase the mother’s height by one-twelfth (first multiply it by 13, then divide it by 12). Finally, combine the output with the other parent’s height and divide the outcome by two. The result shows how tall the target will be. However, bear in mind that Gray’s method is +/-4 inches inaccurate. So, the person might grow four inches less or more than your estimation.
Method #2: Simplified Gray Technique
If you are like, “how tall will I be?” and you are also in a hurry, this formula is the best bet. Combine your parents’ height and divide them by two. If you are a girl, reduce the outcome by 3 inches. And if you are a boy, increase it by 3 inches. The number you get is your estimated tallness.
Method #3: Determining Child’s Height by Age
Double an 18-month-year-old girl’s height to come up with her possible tallness. If the child is a boy, wait until he is two years old and follow the same steps to come up with an estimation.
