A window shade cutting aid includes a hollow sleeve consisting of a front wall, a rear wall, a top wall and a bottom wall and a ruler located on the bottom of the sleeve that has a scale for measuring length. The sleeve has a cutting slot on one side vertical to the bottom wall and running through the top wall, front wall, rear wall and bottom wall. The ruler has a recess corresponding to the cutting slot. The ruler enables users to measure the length of the cutting portion of a window shade. A cutting tool can be placed in the cutting slot to finish cutting operation of the window shade by one pass. Skewing of the side edge of the window shade after cutting can be prevented. The window shade cutting aid may be used repeatedly after the cut window shade is removed.
