Printable Polar Graph Paper (Free PDF)

The grid has 14 concentric rings spaced exactly a quarter inch apart, giving a 7 inch circle, with every fourth ring drawn darker so each full inch stands out. Radial lines run from the center to the outer ring at your chosen interval, and the four axis lines at 0, 90, 180 and 270 degrees are drawn heavier so you can find the quadrants at a glance.

Choose the radial spacing to suit the work: every 30 degrees for quick sketches and pie-style layouts, every 15 degrees for general plotting, or every 10 degrees when you need to read angles closely — that last one gives 36 spokes. Whichever you pick, the outside of the circle is labeled every 30 degrees from 0 to 330, measured counter-clockwise from the right, the standard mathematical convention.

Use it for polar coordinate plots, roses and spirals in a maths class, antenna radiation patterns, wind roses, radar charts, circular knitting and crochet charts, mandala layouts and clock faces. The sheet is a single vector page with no form fields, so it is meant for pencil, pen or a stylus in a PDF annotation app. Print one copy per plot, or merge several copies into a single file if you want a small pad of them ready to go.
