Rule of Thirds

The rule of thirds is a design rule for the composition of a frame in graphic design, UX/UI design, traditional painting, film, or photography. This design technique was first written down by John Thomas Smith in 1797.

The rule of thumb is to divide the frame into nine evenly spaced parts; the image is separated by two equally spaced horizontal lines and two evenly spaced vertical lines. It is proclaimed that arranging the visible objects within the frame along those vertical and horizontal lines creates a more visually appealing composition.
