A traditional grid with horizontal and vertical lines is designed to plot Cartesian coordinates where a location is represented with a horizontal and vertical location. Polar coordinates represent another coordinate system where a location is specified by the angle and distance from a fixed point. This graph paper allows you to plot those points.
This graph paper was designed for 11x17 size paper in the portrait orientation with dark gray lines. Tabloid paper, otherwise known as tabloid size paper, is the size of two standard 'letter' size papers. It's handy for large prints.
For reference here is a list and description of all the sizes:
|A4||A4 paper is the most common size paper. It's 210 mm by 297 mm.|
|A3||A3 paper is like putting two A4 papers side by side. It's 420 mm by 297 mm.|
|A2||A2 paper is the size of 2 A3 papers put together. It's 420 mm by 594 mm.|
