Please provide some sort of explaination with your answer, and if possible an equation or algebriac expression as proof that your theory works.

1/2 their height
Because the angle of reflection equals the angle of incidence.
It does not matter the distance you are from the mirror.

It depends on how far from the mirror you are willing to stand. To see your whole body in a mirror when you are 0m from the mirror it would have to be as tall as you are. The smaller the mirror the further from your body it will have to be before you could see your entire body. There is no limit to how small the mirror can be as long as you can move it further away. To be functional of course, a mirror has to be much closer so a person can see the image well, which means it cannot be much smaller than the body. Which makes sense if you think logically. Most full body mirrors are almost six feet tall and we stand about two or three feet from them.

All has to do with focus. At a given distance a mirror the size of a pinhole could reflect the entire human body. Would depend on how many pixels the minimum was to portray/reflect the body. How pinhole cameras work? Can portray entire scene including total body when moved a certain distance from subject. While it might take a large number of pixels the actual area required could be microscopic.

It depends on the shape of the mirror and the distance you are standing away from it. A convex shaped mirror will distort your immage in such a way that you can be really close to the mirror and see your intire image. It works like a telescope but in reverse.
If the mirror is flat, you can step further away from the mirror to see more of your body. Of course if the mirror is very small, you will be so far away that you will not be able to make out the image, but someone standing next to the mirror will be able to make out your entire image easily even with a very small mirror.

Truth is, the question is not a fair question. Since people come in all lenghts and sizes there is not a specific minimum that can be set. And you did not specify an adult or child. I am only 4'9 so I would not need a tall mirror. Yet others are on average 5'7, their minimum would be totally different than mine.

The length of the mirror will vary inversely as the the distance from the mirror. In other words, the smaller the mirror, the further away you will need to be.

If the person is 5'5" tall, then a mirror that is 5'6" would be great to see the whole body IF the mirror was sitting on the floor... Much would depend also on how far back you stood and many other variables.

it really depends on how tall you are, where the mirror is positioned and how far away from the mirror you are standing.
the bottom of the mirror should be level to the floor you are standing on, and say you are standing 1 metre away from the mirror, it can be 1 metre shorter than you are and you will be able to see your whole body.
