3-6 needs about 12 a day
6-12 needs about 9 a day
12-14 needs about 8 a day
15-18 needs about 7 a day
18-50 needs minimum 5 a day
50-90 needs about 9 a day

Although this can vary from one person to another, some doctors consider four hours of sleep to be the minimum in order to function normally during the day and remain in a position to conduct work related tasks. Nevertheless, determining the minimum amount of sleep necessary is not a precise science, as this really depends on the individual in question. Getting only four hours of sleep for a prolonged period of time may, however, really wear down your system, leading to illness, general fatigue and other health problems.

Ideally, you should get a minimum of 7.5 hours of sleep every night, while getting 8 or even 9 is much preferable. The average Briton sleeps 8.1 hours each night, according to a UK-based survey. Nevertheless, some political leaders have boasted about how little sleep they get, yet how well they are able to function. Former British Prime Minister Margaret Thatcher, for example, claimed that while in office, she got by perfectly well on 5 hours of sleep.

The bottom line, however, is that you should try to sleep for about 7 to 8 hours each night, but that the "minimum" amount of sleep necessary depends on what kind of tasks you wish to perform during the day, and how your body works.

It really depends on the individual. Some people thrive on just cat napping, or 4 hours or so, while others need more, like me, at about 9 or 10 hours. Most people sleep best for 7 to  8 hours though, hope this helps.

It is an individual thing. Most of us need between 7 to 9 hours, but there are many who thrive on 4-6 hrs.

Sleep, as we know, is important to us because it helps restore tired organs and tissues in our body. But how much sleep do we actually need?
For most of us, eight hours seems to be about the right amount. Yet we know that there are a great many people who get along perfectly with less sleep and some who may even need more. A great deal depends on the way we live. But a good general rule to follow is to sleep as long as we have to in order to feel happy and be able to work at our best when we awaken.
There are actually different levels of sleep. There is a deep sleep and a shallow sleep. In a shallow sleep, our body does not get the same kind of rest it gets in a deep sleep, so that after eight hours of a shallow sleep we may still feel tired- But a short, deep sleep can be very restful.
Alexander the Great was able to get a deep sleep whenever he needed it. Once, during the night before an important battle, he remained awake longer than anyone else. Then he wrapped himself in a cloak and lay down on the earth. He slept so deeply that his generals had to wake him three times to give the command to attack!
Normally when we go to sleep, our "sleep centre" blocks off nerves so that both our brain and our body go to sleep. One prevents us from wanting to do anything, and the other makes our internal organs and limbs go to sleep. But sometimes only one goes to sleep and the other does not. A very tired soldier can sometimes fall asleep (brain sleep) and keep on marching, because his body is not asleep!

For a fully grown adult, it is an absolute minimum of 8 hours of sleep. For a small child/baby it is about 17 hours, for an older child it is around 12 hours and around 13 hours for a teenager.

Some people can get away with 6 hrs of sleep, but most experts say you should get 7-8 to be fully rested

According to Professor Jim A. Horne, a leading researcher affiliated to the Sleep Research Centre at the Department of Human Sciences at Loughborough University in England, a leisurely snooze on a Sunday morning does not amount to anything, as it makes no sense to stay up all night or sleep late at night on the weekdays.

Lack of sleep is an open invitation to various health risks including depression and stress and leaves you feeling groggy and irritable the next day. Hence, people who do not get their full quota of sleep at night are usually bound to be unproductive and cannot get too much work done the next day. Working on the night shift is not an excuse to become an insomniac.
An adult person ideally needs six to eight hours of sleep everyday. People who smoke, eat or drink too much, do not get enough exercise or generally neglect their health tend to adopt a casual approach towards their sleep as well. In fact, Napoleon Bonaparte, the exiled French general, once said something to this effect, but of course, in a lighter vein: a man should ideally get about six hours of sleep, a woman should try to sleep for about seven hours and a fool should sleep for about eight hours.

Recent studies suggest mass sleep periods are detrimental to a person's health and can perhaps cause cancer. REM sleep is the only stage of sleep with any regenerative value; thus, one should take 4 or 5 20 min naps throughout the day or simply use brain entrainment to adjust the brain waves for like periods. Or simply switch to a no calorie diet..calories are bad.

The younger one is, the less time is needed for sleep in order to function normally. However, cognitive function will definitely drop if such short duration sleep is continued. When I was 14, my classmates and myself occasionally slept for 4~5 hours.

6-8 hours of sleep are recommended. 6 hours for those 40+ and 8-10 hours for younger folks.

Its extremely unhealthy to be sleeping less than 6hrs a day although you can it would be a very uncomfortable day and you would probably take a "day nap" during the day, you should be sleeping 7 hrs in order to have a nice relaxing day

I have heard many scientists sleep very little but sleep of 6 hours a day is sufficient and necessary for normal functioning..
  More sleep could make you again drowsy...

As per my elders suggestions, the minimum sleep required by a man is eight hours continuous sleep. But nowadays many people are more interested in other activities than sleep. But we will be very much more active, if we have a good sleep of 8 hours.
