Human Height Has Its Limits

[LoLeL]

In fact, Nature imposes a fundamental stature-cap: Mammals in general load their bones to about a quarter of their breaking strength during routine activities. If you doubled height, bone cross-sectional area would increase fourfold (radius squared), while weight (volume) increases eightfold (2 x 2 x 2)! Our bones would be overloaded, and breaks would be commonplace.

Bad as this sounds, things would actually be even worse, says LaBarbera: 12-foot-tall humans would be prone to collapsed arches, bad knees and excruciating back problems; 18-foot tall humans would be immobilized.
So, height limits, absolutely. But fat chance we've already peaked in body girth.

John Wass, a specialist in acromegalic gigantism at the University of Oxford, reckons it would be impressive to survive for long if you grew taller than 9ft.

First, high blood pressure in the legs, caused by the sheer volume of blood in the arteries, can burst blood vessels and cause varicose ulcers. An infection of just such an ulcer eventually killed Wadlow.

With modern antibiotics, ulcers are less of an issue now, and most people with acromegalic gigantism eventually die because of complications from heart problems. "Keeping the blood going round such an enormous circulation becomes a huge strain for the heart," says Wass.

I think the natural limit of average height will be around 6'4

[Pahli]

Don't think you can reach more than 2.5m before things start to really fuck up.

I think about 6'4 to 6'6 is the limit before you suffer adverse health issues because of your height

Only with extreme sexual selection and breeding for it over time like what happened in Netherlands. The height in the US has peaked in the 1950's and remains unchanged today.

I think 6'1 or 184-187 cm is enough/ideal for the men. Even 173-177 is OK.

Nah, probably around 7 ft 1 in (2.16 m), just look at Shaq, he was pretty much normal and a lot more athletic than the average person. I think people like him are atypical, but you can reach that height without any negative consequences.

We will probably get shorter due to all the filthy mexicans that are like 5'4'' average in height.

In reality, 5'5" is the ideal male height. Anything more than that, your center of gravity is too high, your limbs are too long to pack any meaningful muscular surface area without steroids, and your mechanical leverage is bunk. Doctors refer to this as "pushover's disease".

the decline could be attributed to worsening nutrition standards for poor Americans, the New York Times reported. But they said immigration from countries with shorter citizens could also have played a role.

Seems legit.
