A printer tray extension kit which allows a printer to hold and receive longer pieces of paper is provided. The printer tray extension kit includes a base, an extension arm, a support stand, and a crossbar. The base provides a structural platform in order for the printer tray extension kit to hold pieces of paper. The extension arm provides a lengthening element in order for the print tray extension kit to hold longer pieces of paper if the base is not long enough. The support stand provides a structural reinforcement which maintains the printer tray extension kit in a raised position from a table surface or similar. The crossbar provides a structural reference bar which is used to attach the support stand to the base.
