Odd question. Are you asking how big it is, how long it will last, or how deep it is?
It's size is a point of debate, raging from a singularity of practically no size to larger than our solar system depending on the type of "black hole". It should be noted that black holes are simply large gravity wells from which light cannot escape making accurate measurements almost impossible.

To define the lenght of a black hole is nearly impossible to do, at the moment, mainly because you don't have to imagine it as a hole but as a celestial body whose density is so high that it deformates the space and time in shape of a hole. Because the density of a black hole is virtually infinite (Einstein said that the space and time are deformated by a body in proportion to the density of the body), we suppose this lack in the space and time tissue is infinitely long.

A black hole is round.
Typically, black holes are the remnants of massive stars. The hole is a sphere around a mass, such that the radius marks where the speed of light is the escape velocity (Schwartzchild radius).
A black hole has mass, spin rate, and magnetic charge. That's it.

It isn't long. It is around. It is just a very dense mass. No different from a planet or star except it is much more dense. In theory it is infinitely dense. Basically all the mass of a planet or star squeezed into zero volume. Or, if that bothers you, squeezed into a 1 inch ball. I see no important difference between a whole star being squeezed down to 1 inch and down to zero. Even at 1 inch it is so dense as to defy imagination.

Black holes don't have lengths, really. If what you're referring to is the event horizon, this varies with every black hole.

There is a HUGE difference between a star being squished into a one inch ball, and a point with zero mass. A one inch ball has a definable density, which can me measured.. something with zero mass has an infinite density, so even if we could somehow "squish" a grain of sand to have a zero mass.. it's would have an infinite density..

The same length as a piece of string
