one pixel is the size of a pixel, the size very's for all pixels sometimes pixels can be

huge

and sometimes they can be

tiny

(I hope this kind of answers you question, if not someone else probable knows)

 <From Wikipedia, the free encyclopedia>

In digital imaging, a pixel, pel,^[1] or picture element^[2] is a physical point in a raster image, or the smallest addressable element in an all points addressable display device; so it is the smallest controllable element of a picture represented on the screen. The address of a pixel corresponds to its physical coordinates. LCD pixels are manufactured in a two-dimensional grid, and are often represented using dots or squares, but CRT pixels correspond to their timing mechanisms and sweep rates.

Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color image systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black.

In some contexts (such as descriptions of camera sensors), the term pixel is used to refer to a single scalar element of a multi-component representation (more precisely called a photosite in the camera sensor context, although the neologism sensel is sometimes used to describe the elements of a digital camera's sensor),^[3] while in others the term may refer to the entire set of such component intensities for a spatial position. In color systems that use chroma subsampling, the multi-component concept of a pixel can become difficult to apply, since the intensity measures for the different color components correspond to different spatial areas in such a representation.

The word pixel is based on a contraction of pix ("pictures") and el (for "element"); similar formations with el  for "element" include the words voxel^[4] and texel.^{[4]   never mind this is a bunch of monjo jumbo, this is most likly useless}

I think every 1000 pixels are about 10^3 pixels big.

I hope that helps.

The volume of a pixel is ZERO.  a pixel is a 2 dimensional construct thus has no volume.

Actually I was looking in the source to see how many bytes a pixel is (class Element). I'd have to do sizeof() though which means that I'd have to compile TPT. Ew.
