The attached pages are grids that can be useful for perspective drawing and graphing. The images are sized to fit A4 (210 mm × 297 mm) paper with a specific printer. If the image frames will not find into your printer’s limits, allow the printer to crop the edges. Do not resize the image. Doing that will alter the scale of the grid.
Print only the page you need.
The grid interval refers to the spacing between consecutive vertical lines.
On the graph paper, the interval is the spacing between the darkest lines. These intervals are in turn divided into ten subintervals, with secondary lines on multiples of five.
