To get the skeleton:
skelImage = bwmorph(binaryImage, 'skel', inf);
to find the number of pixels in that:
theNumberOfPixels = sum(skelImage(:));

Here are the link gives the both real image and skelton image
real image : http://imageshack.us/photo/my-images/401/0mbt.jpg/
after skelImage : http://img36.imageshack.us/img36/1989/csg8.jpg
I got number of pixels as 1193
If we compare the both real and skel image,
the horizontal and vertical lines were different in widths with respect to each other
My doubt is why don't we get the width as same as the real image in skel image ?
How can I know the horizontal and vertical line length in pixels from total number of pixels (1193 pixels) ?

Skeletons are only one pixel wide - that's the definition of them. Perhaps you were thinking of the binary image, like
binaryImage = realImage > 30; % or whatever value you want.
This will have some width to the lines.
