This screenshot was uploaded at a resolution of 1600x1200 in order to represent Doom's native resolution (320x200) at a proper 4:3 ratio without blurring pixels.

1600x1200 is the smallest standard screen resolution in which both the width and height are multiples of Doom's native width and height. Each pixel has been blown up to a 5x6 rectangle in order to properly emulate the aspect ratio in Doom.
