Is it in all schools that tall people dont have as good of a stretch as the short and do the short people seam to be really fast but can be taken down fast with a good kick from the tall person?

and do you think that a person thats 150 lb and 5 ft. 5 in can beat a person thats Weight, 225 lb Height, 6 ft 4.5 in

they are the same age 

the little person has 30 years of martial art training and is a 4th degree black belt and has had many life time achievement award for tkd.. dose Muay Tai Kickboxing to.

the tall person has a wrestling back ground (nine-time world champion) and has done martial arts when he was younger .... 

sorry if this is a bit of an ignorant reply, but ... ???err, what??? :)

I got beat but a little girl that barely came up to my waist she just punched and moved in close, she chased me out of the ring twice. 

It depends on the contest in my mind,  I get beat by some people in no contact that if we had full contact might go down with a single punch and kick by me. 

not always; I'm around the top ten most flexible in my class (beaten by blackbelts and a profesional dancer that takes the #1 slot), though I am very skinny.

I do think that the weight has a bearing on it though, mainly because of the general level of fitness, whereas a person cannot change their height.

A taller person has the advantage of reach, and often power as well as the leg has longer to accelerate, or to push through depending on the kick and range. The disadvantage is that it takes longer to chamber the kicks afterwards, leaving them prone to counters. and it can be very hard if the smaller person gets in close.

and whats with the weird font post; trying to make us work for it?

Who wants the 'win' more? That'd have a bearing on the result

If you mean Olympic sparring, the shorter 1 is definitely capable of winning the taller 1. Just close in and the taller person's kicks dont score.

If you mean real fight, the shorter one also can win - the usual, close in, guard head, kick groin, run.

Looks (quite literally) Greek to me!  Would you be so kind as to repost in the vernacular?:)

Tall and thin is a definite genetic advantage in TKD.  Case in point: heavyweights Kim Je Gyung (1992 Olympic gold, 10 world championships) and Moon Dae Sung (2004 Olympic gold). 

I'm 5'9" and 200 lb; just last week I got a mudhole stomped in me by a long-legged 6'3" kid (30 years my junior).  I just couldn't get inside fast enough to even get a touch.

A shorter player with good explosive speed could stay in tight enough to score on a taller player.  Work the angles!

I don't think size matters when it comes to a match. Skill can change any scenario when compared to size, weight and height. I have seen a large person take down a small and have seen a small person take down a large one. If it mattered that much (size I mean) what good would learning self-defense be? I think if someone wants to win they will.

I find it quite awkward sparring as I'm a really average height for a girl (5ft 4.5in - yes the half is important!) with short legs and a long body.

But even though on paper I shoudl never have bothered with a kick-heavy sport such as TKD, I manage to pull it off with good flexibility and speed (and a great coach).

I've won a few tournaments inc as a yellow tag v a blue tag in the final who was a good three inches taller. Her legs were better, but I got inside her range and used my hands (ITF TAGB rules). I try and get my weight right down so I'm a lightweight so I'm not disadvantaged by my height  - (ie the taller you are, the heavier you tend to be) but in my last tournament I was done by some very dodgy scales that said I'd put on 4kg overnight and was put into middleweight.

I'd been practicing a hook kick to the head to get some extra extension on my short legs but found it wasn't needed - just loads of quick sidekicks under the arm into the waist. So there is a way - its just a case of being flexible in your approach.
