A parking lot painting template for determining the location of successive parking stall stripes or curb stripes accurately and subsequently painting a straight line in the desired location includes a main member, a rail member, and a pair of curb members. The main member and the rail member combine to form a frame which is of a length corresponding to the width of the parking stalls such that a user may align an end of the main member with a stripe and accurately determine the proper location of the next stripe. The main member and the curb members combine to form a frame designed to slide securely along a corner edge such as an existing curb and accurately paint in the proper location.
