Grid Readers 

To make grid readers, download PDF of grid reader you want and print onto clear transparencies. Make sure your printer is set to print page as "actual size" or set to 100% scaling. Failure to do this may result in a grid reader that is not accurate. Laminate all grid readers with a .5ml sheet.

Center punch all corner grid readers in the corner so you can use grid readers with your pencil. Make center hole in all protractors and attach a string to make protractor easier to use.

Please contact LISAR if you would like us to make you any of the grid readers provided below. Email here
