ABSTRACT:
An apparatus for standardizing typewriting margins comprising a front sheet having lateral and longitudinal edges which has a window, and a back sheet attached along a seam adjacent three edges to the front sheet which leaves an opening along one edge. A leaf of paper is placed between the front and back sheets along the seam for holding the leaf in place. The window is of a certain given size such that the portion of the leaf showing through the window is the portion to be typed upon. The predetermined margins on the leaf of paper, both lateral and longitudinal, are covered by the front sheet. A scale is disposed adjacent a lateral edge to indicate the number of typewriting spaces remaining before a predetermined margin is reached. Graduations are disposed adjacent both longitudinal edges for indicating the number of lines remaining before a predetermined margin is reached.
