How to grow 2 cm taller or 3 cm taller

If you want to find out how to grow 3 cm taller in a safe and effective manner, then listen up.

There are all kinds of dodgy height programs and regimes out there, but the truth is that growing 3 cm taller is far from complicated.

But at the same time, we need to be honest and say: Not everyone is capable of getting 3 cm taller.

Can you grow 2 cm or 3 cm taller in a week?

Is it possible to grow 2 cm or 3 cm taller in a week? No, it’s not possible to grow 2 cm or 3 cm taller in the space of a week because human bones don’t grow this fast.

Even when a child is going through rapid physical development during puberty, they can’t increase their height by 3 cm or even 2 cm in a week. It’s just not possible to shortcut the growing process.

Now, if you’re a fully grown adult, then it’s highly unlikely that adding 2 cm or 3 cm to your height—by way of bone growth—is possible. More on that later on.

Is it possible to grow 3 cm in a month?

Is it possible to grow 3 cm in a month? No, in the vast majority of cases, it is not possible for a person to grow 3 cm in a month or a similarly short timeframe.

Now, if someone has the genetics to be really tall and is currently going through a growth spurt, then it might be possible for them to get 3 cm taller in a month.

But, for the average person, a 3 cm height increase in just one month is not possible because their bones simply won’t lengthen quickly enough to achieve such a height gain.

How can you actually grow 3 cm taller?

Now that we’ve established that growing 3 centimeters taller takes quite a bit of time, how do you actually go about getting 3 cm taller?

Well, first of all, you probably need to be going through some kind of growth spurt.

Sure, some people grow much later than others, but few people are true late bloomers in that they grow into adulthood.

If you’re in your early or mid teens, then growing 3 cm taller (and perhaps even more) is very much possible. 

But since both your rate of development and your height potential are governed by genetics, there’s not much that you can do right now to get 3 cm taller.

That said, eating a nutritious diet, sleeping properly, and getting plenty of exercise—when combined—can definitely have some impact on your height.

But if you’re an adult, then you won’t be able to get 3 cm taller or even 2 cm taller because your growth plates will almost certainly have closed.

How long does it take to get 2 cm or 3 cm taller?

Presuming that you’re going through puberty, you can grow 2 cm taller or 3 cm taller in a matter of months.

Now, height growth isn’t linear, hence the term growth spurts. So don’t measure yourself every day expecting to see an increase, because any amount of noticeable height gain is certainly not going to happen overnight.

Of course, if you’ve stopped growing, then you’re not going to get 2 cm taller or 3 cm taller in any timeframe.

The only plausible way that an adult can “get” 2 cm or 3 cm taller is by improving their posture significantly (and presuming that it was terrible to begin with). 

But even a big improvement in posture is unlikely to result in more than a centimeter or so of height gain.

In summary

As with virtually any amount of height growth, getting 3 cm taller pretty much comes down to making the most of your physical development during puberty.

It might not be the answer that you were hoping to hear, but once your growth plates have closed, you can’t lengthen your bones and gain additional height.
