![]() Since the pixels are now set to the same resolution, it is the image, or document size, that shrinks or expands to fit. ![]() The picture below has too few pixels and so have resized to the point where the pixels are larger than the monitor dots and the image looks either bad, or even useless as in the 12 x 8 pixels image.įigure 2 Although blown up to the same size as the previous image, this image is made up of only 120 x 80 pixels and now we are starting to see the actual pixels, which is called 'pixelation.'īelow are the same images as before but resized so that the pixel resolution is 72 dpi to suit the monitor. The image above has a pixel size smaller than the monitor dots and so looks good. The aim is to have enough pixels, which when resized to fit the image size, are smaller than the monitor or printer dots. ![]() So while both 'image sizes' may be the same, the resolution of each is clearly different.įigure 1 This image is made up of 1200 x 800 pixels and looks to the eye like a scene might look in reality. But each copy is made up of a different number of pixels which just expand in size to fit the image size. Below the same image is shown twice, both times at the same image or document size. Pixels have no set size, they just expand or contract to fill the space available.
