Not Much Fits

The average height for a man in the UK is 5ft 9.

The average height for a woman in the UK is 5ft 4.

So you could say any height above these could be considered tall.

Stastically speaking you are considered tall if you are a woman over 5ft 10 and a man over 6ft. As the heights get taller you belong to a smaller group of people. For example there are alot less people 6ft 6 than there are 6ft 4 and far fewer still over 7ft.

I found some interesting US figures on being tall here.

It appears that from about 6ft 4 upwards tall people are statistically ignored.

“When allocating space for car, bus, train and plane passengers, and considering life-jackets or other emergency equipment, people over 6ft4 are ignored completely.”
